Yes buy a sub I'm of the opinion all Klipsch speakers can benefit from a sub or two. Nice speakers I had a set of those and KLF 30's.

That is really cool!

We lost our house to a fire back in June and most of our art was destroyed. One picture in particular always brought me a lot of joy and I suspect I will look for another copy. This is "Peaceful Feelings" from an Israeli artist named Dorit Levi.

Virtually all speakers benefit from a well-integrated subwoofer.

[bolding and italicizing mine -- GC] 1) As you may know, it is quite literally in your head -- and mine. Some used to think it happened acoustically in the air, but back in the '70s, Scientific American published an article entitled "Auditory Beats in the Brain," using tight fitting headphones. They found that the difference tones indeed happen in the brain, not due to any interaction of the two tones in the air of the room. Monaural signals didn't work. That title was changed from "Binaural Beats in the Brain" at some point. Too bad; they lost the alliteration, which entertained my brain, but there's too much going on in there, anyway. 2)I don't have a La Scala, but I do use a Belle Klipsch as a center channel. Both used to be spec'd down to 45 Hz, but that was in the +/- 5 dB days. And it was in the vinyl days, when mastering engineers tended to roll off bass down there, pretty near 40 or 45 Hz, to save space for needed bass in the fff or ffff sfz finale of Classical or Romantic period music. Sometimes the record companies failed, even then, so my friends and I would crank up the bass along with the volume. Of course, we knew how it should sound, because our traveling orchestra shook the seats and pealed the paint off many walls in many halls. We never blew a really good woofer in a full range speaker, but we blew the woofers in a pair of medium priced speakers with Ben-Hur (1959 version), but we don't feel too bad, because, reportedly, Ted Turner did the same thing, with the same movie, with his good speakers. The Vintage La Scala is now spec'd down to only 54 Hz (+/- 3 dB), and the New La Scala AL5 to 51 Hz (+/-4 dB)... Sooo ... I wouldn't pump up your beloved La Scalas with bass boost, even with the 48 Hz and down choice. 3) I know you don't want a sub, but how about one of those horn loaded DIY ones you could put in a rear corner, Xover at about 60 Hz. They should be clean, tight, and "fast" just like the La Scala.

It is funny because it is true. When I got the HLS installed I found every loose item in my house. The best thing that happened was I had a sputnik style light installed but some of the bulbs were out. When I cranked up the sub it vibrated all the filaments together and the bulbs came back on. Sadly if I want all the bulbs to light I gotta really crank the sub.. I could replace the bulbs but where is the fun in that. @Chief bonehead

We are also auctioning others speakers.

Her name is Chami and she loves that dang ball. She is a good trouble.

More power to you, my friend. I would never have the patience nor skill that you obviously possess to take on a task like this. Your suggestion to remove the tweeter protection diodes and magnetic screws was about as far as I would go in terms of messing about with these speakers. The only other thing that I'm considering other then the possible experimentation with a sub is getting some crossovers from Crites since they're an easy swap in. Other then that, these speakers will remain as is. But as always, I thank you for your comments.

These are my 1976 models stained in cherry with a cherry strip covering the raw ply edges. They have a coat of satin poly for protection and turned out nice, I think. I’ve had them quite some time now and I can’t remember where I picked up the grilles.

Did you look through some of her other pictures in the same series? I think she does some really fun stuff. Music and joy...how can you go wrong? 😃

In my home town there was a straight, almost flat stretch of road that had a posted 25 mph speed limit for about three miles, because there were several schools along the way. I was aware that it was also a speed trap, so I always drove at the limit. One dark evening about 8:00 I was driving this road, and I saw a pair of headlights behind me, coming up fast. The car got so close that I could no longer see its headlights in the mirror. So I slowed-down. The driver refused to back-off or pass, so I slowed-down more. Finally we were crawling along at less than 15 mph when he gave up, floored-it, and passed me. It was a local cop. You can guess what he was trying to do.

Reminds me of a county sheriff I once knew of. Wrecked lots of cars, so they told him he'd have to provide his own car. He drove a Mustang GT and would instigate people to speed and turn the lights on. Glad I wasn't the one dating his daughter.....

Generally speaking, an EQ should be used mainly to reduce peaks, not raise dips in frequency response or try to squeeze output beyond the capabilities of the speaker.

This is the art that is hanging above the left channel La Scala

Mechanical/air impedance by air compression vs. running a driver with no cabinet at all. The difference is measurable and translates to less power draw from the amplifier by way of differential electrical impedance that results in the comparison. Again a total SYSTEMS approach to sound reproduction.

I know it's not the traditional way, but I had mine professionally painted piano black! But love the natural wood look! Did my Cornwalls natural!

Putting wings on a boat LaScala is not designed for bass below 50HZ I added a front firing sub as an experiment I seldom feel the need to use it LaScalas offer the finest human voice reproduction in the industry, IMHO Forcing the LaScala lower may damage the speakers. I would never do it

Although you already have it, I would not think it a good idea to give 14db of boost at 20Hz. Unless you are trying it at night for low level listening. Another option, if you could find one, is to locate a Waves MaxxBass 102. It uses the effect of two frequencies generating the fundamental frequency... Waves quit making them, but they come up for sale every so often. ''' The clever designers of the Waves MaxxBass 102 have figured out how to make physics work for them, using a phenomenon known as the Law of the Missing Fundamental. The Waves MaxxBass 102 convinces the ear that it hears frequencies lower than those a speaker is actually generating. Long used by pipe-organ composers to produce gut-wrenchingly deep notes, this principle states that if you play two closely spaced pitches, the ear perceives a third tone at what is called the "difference frequency." Simultaneously playing a 110-Hz A and a 165-Hz E, for example, creates the illusion of an octave-lower A at 55 Hz. Waves MaxxBass 102 uses this psychoacoustic effect to extend the low end of car stereos, portable music players, and even audio CDs. Waves MaxxBass 102 has also begun appearing in computer speakers such as Waves' own Maxx Home MiniWoofer. It's virtually impossible in the labs to differentiate between physically real sound and MaxxBass-generated output. Furthermore, because these virtual waveforms exist only in your head, MaxxBass speakers aren't nearly as vulnerable to the acoustic effects of room placement.

I guess I'm confused. If you have no wish for "more bass", why do you even want to bother with such a device? No amount of EQ is going to make them go lower. You might only increase output where they already go. But you said you don't want "more". I still contend that you have two choices. (Well three if you count the ported box mod). Live with the bass as is. Add subwoofer(s). Oh, and one more I forgot. Dump them and move on. I assume that's not one you would consider.

Because tubes have a "bloated bass" (greater impedance interaction) and now you have accurate bass (not affected by impedance much if at all, with it's load independence). I replaced an Ayima class D ($80), which favored the top end in a very detailed manner. I don't want to say the bass was thin, but the single PA5 really added so WHUMP to the bass, and only down to 80 Hz. where I cross into the Mono Seismic Sub (which was untouched before or after the swap). So my bass got fatter and your got thinner, but I lost NONE of the mid and high end detail I had. At 106 db sensitivity into 8 ohms, I'm still using less than a watt per channel, yet the way that PA5 just grabbed hold of those Voice Coils and made them do PRECISELY what they were supposed to do, is still an incredible sound, which I enjoyed last night yet again discovering stuff I never heard before on familiar music!

It always happens so I would not fret over it too much. This thread would have died out long time ago with just a few post if it had not deviated from original poster to some degree. The point is the OP probably got an answer to his question early on in this thread. Maybe someone learned something else from this thread which I would not say is a bad thing.

This soooo stole the show though and still remains in so many hearts throughout the world. He was 76. From 1967 WITH the lyics... If you've never heard it "Just Say NO" because it will haunt you forever!

Very sad to wake up to the news of the passing of Procol Haren's Gary Brooker the other day. His voice and piano playing were such a distinct trademark for the band…later adding to his work with George Harrison and Ringo Starr as well. Soooo many great songs "A whiter shade of pale" hands down stole the show. Found this one with drummer Michael Portnoy not only playing but also handling the lead vocals. A great cover!

Modified AA. -6dB setting for the squawker on the autotransformer. He’s selling for cost of the parts, so I would consider this a pretty good deal.

Ok, as always, here comes my very cheap and unfortunately further devalued 2 cents due to inflation. I know, svberger, that you are satisfied with the sound of your Lascala. So it's more a comment than a suggestion. I fitted my Lascala, also from 1977, with new internal wiring 16 years ago, Kimber 4TC. Like here (at that time still with an ALK xover) This may not have been necessary but as part of an overall cosmetic restoration I did it, especially as all the electronics and drivers were removed for the restoration anyway. Originally, the underbody is sealed with a sticky tar compound. 16 years ago, some of this compound was still liquid. After wiring and reinstalling the woofer, I screwed the base plate back into place without doing more, at least I thought it was sealed again which I think, it was because it was a bit liquid. When I reactivated my Lascala more than a year ago, I restored much of it to its original condition as best I could. But unscrewing the base plate 16 years ago has not left me in peace. I always thought that the bass could play with a very little more energy. At least that's how I remembered it from the time before I stored them away. Then I stumbled across other threads here in the forum where people had resealed their Lascala after repairs and so on. So I did the same 5 months ago or so. I used a similar tape to this one with a link to an American dealer: https://www.parts-express.com/Speaker-Gasketing-Tape-1-8-x-1-2-x-50-ft.-Roll-260-542 When I loosened the base plate again for this purpose, the first impression was that this tar compound, which Klipsch originally used, was completely hardened and brittle after 44 years. It was almost certainly no longer an airtight seal. And the Lascala absolutely! needs an airtight seal for the horn to work properly. Now I can't say whether this happened because I had loosened the base plate 16 years ago, or because independently of this, this tar compound simply no longer seals smoothly and flexibly due to the long years, regardless if the plate was removed or not. It is very easy to loosen the screws, but you have to loosen the base plate with a lot of feeling with the help of wide screwdrivers or better with even wider chisels. The tar mass, when it is crumbly and dried out, makes a big mess on the floor, so it is better to lay out some paper first. I used a spatula to straighten out the excess tar a bit, but it doesn't need to be removed perfectly because the new sealing tape that will be applied further in will do the job of sealing anyway. I had a piece stuck under my slippers and I messed up three rooms, to the delight of my wife. When I cleaned the smears on the wooden floor, I had to use some Isopropanol for hours but that's just by the way. Now for the result. As you know, I like to appreciate subtle little changes, but sometimes psycho-acoustically they can have a very positive effect on the overall experience of the sound. It can change the "whole" which, as you know, is more than the sum of its parts. In fact, I experience a difference in sound that is not just imagined because I was sweating and my knees hurt. The Lascala plays subjectively "deeper", as if it were tuned a little differently. As a side effect, the articulation is also better in the high bass frequencies, where the bass joins the squaker. E.g. male voices, a trombone, etc. It might be worth a try to check if the very old tar mass is still doing its job well or not. Of course, physically, the Lascala does not play lower than its construction allows. But my impression is that it plays less deep when the doghouse is not 100% sealed. And this difference can create exactly the impression of whether the ear is even more satisfied. Don´t be confused, you must not remove the woofer. I did it only because the quarter felt stripes shrunk over the years and I added some felt to seal the gaps as well.

It's what we do with every long thread.

You absolutely should. I'll warn you, don't hear it until you are ready to buy. You will have to have one if you hear it blended well with someone that has a clue. If you can pick the sub out easily and it isn't blended, that person did not implement it well.... It can be subtle until calls upon at which point it can head towards violent if you like and bring enough power...

May work well for rugged direct radiators, bad idea for horn loaded woofers with minimal excursion and a short horn. It won't work, I'm sure

Cabo it is! Doing the whales tomorrow although we saw a bunch of them today from the shore. At airport, saw a WICKED zip line. Doing "a" Zipline Thursday, don't know if it's the wicked one I saw or a kiddie line. Dude said it was big but I'll wait and see. I'll be wearing bright clothing should they need to find me

Not as carefully as one might suspect. First mod was getting rid of the AB x-over. The speakers were 30 years old and putting new caps on AB's did not seem worthwhile. I went with the 4500 based on discussions with several member here and with Bob Crites. This move also made replacing the K77 necessary. That was a very distinct improvement in overall clarity. I cannot be sure if it was due to getting rid of the AB, having new caps, the new tweeters or a combination of all three, but it was a nice update. The other changes were due to the fact that I ended up with a pair of absolutely beat to hell LaScalas that I was going to bring back to life and needed more parts. I wanted the Belles to have the newer components so I put the old drivers into the LS and the Belles got the Altas driver and the Kappa 15C. The older K55M and K33 went into the LS. The mid driver did not make much of a change that I could hear. The new woofer seemed a bit more clear and blended a little better with mids. The K77, the K55M and the K33 all still live on in my LS that I use in my warehouse or outside functions and they all still sound great. I added a AA xover with new caps to the mix.

Thank you Nicholas, Dina, Robert, David H and Jeremy Wow, just wow, and a big thank you to everyone who used the option to donate the credit card fees, you would be surprise how $3 here, and there, really adds up and we really appreciate you selecting that option.

Adding that much boost at 20Hz to a La Scala is not recommended as stated in the owners manual for the electronic subwoofer. As it explains the type of speaker to use the device with needs to handle the amount of excursion and also control it or else the results will at best sound bad and at worst destroy the woofer. You like to experiment then go for it and let us know how you make out. Just make sure you are experimenting at very low levels at first and if things sound off then just stop the experiment. If it sounds like the woofer is still in control and you don't hear any strange noises from the speaker very slowly increase the output level but I still not recommend using it at loud levels as you will risk damage. 20Hz is really getting to where you don't hear it and it's more of a feel thing, push air and shake stuff which requires lots of movement (excursion), so you may not even hear your speakers being damaged until it's too late. Wavelength increases as frequency decreases, I doubt the La Scala will sound good with this device and most likely just become boomy and bloated sounding.

Nothing "bad" going on here. It's all Bullshit! But it's GOOD bullshit!!

My wheels are turning.... I like your LaScalas.... there's a guy near me (in Maryland) selling a beautiful pair of Khorns in cherry (2008 AK5). I wonder if there is a way to make something happen.

Felt a little bit nostalgic today and I’m now giving an old favourite album a spin Artist - The Moody Blues Title - A Question Of Balance Album ID - https://www.discogs.com/release/3032878-The-Moody-Blues-A-Question-Of-Balance

Good evening all ! Two of us will be syncing up some vinyl this evening in about 40 minutes at the TOP of the hour (from this posted time). David Gilmour on the UTurn this evening. I believe we are going to join Paul with some Bill Evans if we can dig up the same recordings, but surely Marillion is on the list. Stand by for more 🍷

When the 1812 was released, the cover read "Caution! Digital Cannons," and the interior of the booklet warned the listener that "the cannons of the Telarc 1812 Overture are recorded at a very high level. Lower levels are recommended for initial playback until a safe level can be determined for your equipment." Reviewers also issued cautions: "Just be sure the volume isn't so loud that one of the shots spreads pieces of speaker cone all over your floor," (Digital Audio); and "Its peaks would crack your window panes and maybe your speaker cones, too." (Knight-Ridder Newspapers). The disc became Telarc's best-selling recording of all time, with over 800,000 copies sold, and for well over a decade has been the audio demo disc of choice. source: https://www.vinylgourmet.com/en/music/1540-tchaikovsky-1812-overture-lp-180g-vinyl-cincinnati-symphony-orchestra-erich-kunzel-telarc-records-usa.html Although the dynamic range on this disc sounds absolutely stupendous, it is only about 45dB between the softest and the loudest (bass drum) musical passages. This may seem absurdly low to those of us accustomed to thinking in terms of 110dB fortissimos, but it is roughly 15dB more dynamic range than is on the statistical average of symphonic LPs, and 5dB more than on any audiophile disc we have encountered! When we consider that a 10dB change sounds to our ears like a halving or doubling of volume, it is no wonder that this latest from Telarc sounds like such a blockbuster. Add to that the fact that the loudest parts are cut at extraordinarily high level (higher than on most 78rpm discs) for drastically reduced (by almost 10dB) surface noise, and it becomes obvious that this disc has established a new high for analog-disc information capability. The fact that it will reproduce throughout without breakup (by some phono systems, anyway) is in its turn a tribute to the advances in cartridge design in the past few years. (...) the hard-to-track cannon shots on analog are absolutely lethal on CD—though not hard to track! If your power amp is capable of ripping your woofers apart, the cannonshots will give it the opportunity to do so. Telarc's warning in the booklet (and on the album cover) should be heeded. source: https://www.stereophile.com/content/recording-october-1979-telarc-1812-overture
