Technical insight regarding that specific modification of a Chorus. http://www.nutshellhifi.com/MLS/MLS3.html Results not applicable to the La Scala, but the article does a good job shedding some light on the level of component interaction when one delves into modification.I'd try this - it's very inexpensive and has a large bang for buck.

Well, it can be a can of worms if you don't fully understand what is taking place and/ or are attempting to do so with a passive x-over network in-place. I didn't suggest you try it in this in your instance. I just mentioned it, to bring to light that there are significant, non-invasive methods of extracting every drop of performance, out of the design, that don't require physically modifying them. Bi-amping can be a BIG step in that direction, for minimal outlay, with certain set-ups (like 2-channel analog). Room treatment can be another fruitful option.It's easy to consider a horn, tweeter, or network swap for a Klipsch Heritage because everything is out in the open, everyone appears to know something about their alleged shortcomings, and the candy store is brimming with product, but that doesn't mean you should. Suggest swapping out the woofers to a B&W 800 series owner, for example, and they'll ya, "Get bent!" But that type of suggestion flies rampant in the Klipsch community. Stick around here long enough and I'm sure someone might have you convinced you need a HerFLaJub-Khoru.
Baby steps bro...baby steps. If it's any consolation, I've found more discrepancy in my electronics (levels, response, phasing, processing, grounding) than in any other part of my system. Impressive results, all without touching my speakers...aside from the dust cloth.I am suddenly going far deeper into this project than I ever imagined.

+ 2[Y]Hi BillyBob,
You are not alone. I too, visit the Tube, from time to time. It's a great source of entertainment; especially for classic videos and DIY instruction.
-
Agreed. And the best bang-for-the buck 2 channel addition, for the La Scala, is to Bi-amp them, in my professional opinion (no modifications required).My honest, and sometimes unpopular, opinion is to defer the upgrades.
-
Bingo.You'll be able to tick-off the neighbor good and plenty before that combination runs out of gas thanks to the RB's generous sensitivity. It won't get your clothes flapping, but it'll certainly be loud, even at 40W playing music with a 10 dB crest factor.Doubling power output to the speaker increases the sound level by about 3 decibels

Problem was, who was going to buy them? It's just like the 2008-10 Chevy Cobalt SS turbo. People that bought them, neglect them. People that would truly appreciate what a marvel it was beyond its packaging, didn't believe the manufacturer when they were being produced. Likewise, 6-8 years from now, models in good repair will be very desirable. It's purely a matter of the consumer taking the product seriously while it's still available to the market. I didn't find out about the XR series until well after production ceased. It's a great excuse to always keep your ear to the ground when it comes to technology. I took a breather from the Hi-Fi market for just a brief time, and almost missed the boat completely.

So get on it! You would if you had access to a good electronics text, some basic diagnostic tools, and you actually built an LC network from scratch. It's quite a learning experience to listen to something you schlepped together. Electronics aren't intuitive, otherwise everyone would be building and fixing their own stuff. Instead of pimping out your home or toy like every other Tom, Dick, and Harry, buy a kit and some used tech gear to help expand your understanding of things that truly mystify you. No one else is gonna force this stuff down your throat, and it is a very gratifying experience once you start to understand the concepts that drive the electronic design. You have to want it for yourself.I wish i understood the mechanics behind crossovers much better than i do.
Boy, if I had a nickel for every time I heard.....[^o)]It is such a simple circuit too
-
How much power is too little? Not enough to hear would suffice me. ;-) As far as blowing out your speakers..how loud is "loud enough" for you? Until you know that number in dB SPL, for certain, power figures will be meaningless, regardless of design or intent.I'm looking into getting a pair of RB-51 IIs, but right now I've got an old reciever rated at 40W RMS per channel. Until I can replace the reciever, do I run the risk of blowing out the speakers? Thanks.
-
My recommendation? NO. Not worthwhile. However, picking up an AS-EQ1 instead, would be very worthwhile. Once you get your DTS-10's signal chain transfer function linear, they'll match up to the La Scala's even better. You will realize upper bass performance you thought you'd lost for good by running a separate sub.My motivation? well, I've been happily enjoying my LaScala's, but last week heard Cornwalls for the first time. They were in 2channel full range, and I was very impressed.....would going to CornScalas be worthwhile in that application?
-
Certainly. I've heard them too. Like listening to a high sensitivity version of Vandersteens. But it wasn't enough to get me to move on them over the La Scalas.I've heard the SH50's, and to be honest, it would take a critical ear to appreciate the advantage over the LaScala.
What is the motivation for your curiosity?I can't help but wonder though about other options...
-
Danley SH-100's, SM-60F's... and the whole gambit of decent satellites from other manufactures. Lot's to pick from. If you do the math...The La Scala bin is about as small as it gets if you prefer to keep things "on the horn" down to 100Hz.I can't help but wonder though about other options...
-
$150? Nice deal you got there. Good find.

I wouldn't recommend a 4 meter span at line level in home, no matter the cable choice. EMI, regardless of shielding, can be problematic in unbalanced runs as short as 3/4 of a meter. 4 meters would make for an excellent antenna. Any chance of keeping the runs under one meter? That would reduce the potential for induced noise quite a bit.
-
Although this makes perfect sense, and will work audibly to some extent. To do so, would not be taking full advantage of the capabilities of a component subwoofer. By high passing the mains, the owner can plunk the crossover frequency in the linear regions of both the subwoofer and mains, opposed to hooking it out on the lower end of the main's bandpass, where all kinds of phase chaos can be taking place. In addition, when boundary loaded and strategically placed, a component subwoofer is very likely to perform better than the mains in the bass range all together. The total components required to pull off a good sub install can be expensive and tedious to implement correctly, but they sound so-darn-good when done right. To recap, although hooking it up and dialing it in where the mains roll off may suffice, in practice, it is far from a better way to hook up a sub to an amp.Why would he need a high pass filter? Just run a full signal to the mains and adjust the crossover on the sub to take up where the mains roll off.

Thanks guys! I fussed around quite a bit to get it sounding this way. From airplanes, trains, neighbors, the cat, my refrigerator, cell phones, the HVAC,...it becomes daunting to get things quiet enough around here to film because the camera picks up everything. Other times, I think I've got the wrap on a cool vignette, but once it's on film, it still doesn't sound right...frustrating yet perplexing to say the least. I understand it's a little quiet. I've been experimenting with that honestly. It's been a ballet when setting the gain structure. ~70dB SPL at the mic, and CD music comes across hush, but Blu-rays with their "take-no-prisoner" dynamics can still overwhelm the audio track when scenes pick up the pace. Inception was recorded at -23 dB from reference and the bass line still saturated the mic

I hear ya..I was there three years ago.I want a bigger sub sooo bad..
-
+ 1In addition, once the subwoofer is connected in that fashion, the mains still require a high-pass filter in the form of an active crossover network, like an old Outlaw ICBM-1 for example. The Signal Processor / EQ I/O's are where you'd insert that device to accomplish that.That wont work for a sub, you'll have to use speaker wire hookup.

If you've got a very good set of cans or ear buds, you'll hear what the video has captured. As one guy on another forum put it, "...I didn't know youtube sound could get that low."
-
Certainly not. :-( It's a compromise given the space constraints of living in a one bedroom apartment. I wouldn't let them sit in storage, so I use them regardless. If the girlfriend ever agrees to flipping the entire living room around, I'd be able to spread them out, but for now this works for me.Is that a temporary setup for your LaScala's or is that preferred to have them side-by-side with each other?
Very nice video of your Cornwalls!! [Y] Looks as though the media moguls got their meat hooks into the second one though..[:@]I'll bite crappy but here they are
-
Sure you do. Just 30 minutes online, and you've already brought the hate along with a nice blanket statement. The build was covered in a thread here: http://www.diyaudio.com/forums/subwoofers/163380-volvotreter-20hz-tapped-horn-build-pics.html For crying out loud, it's a video showing some speakers playing music. If it was solely about cabinet construction or appreciation, I would've titled it "Roy Underhill builds a sub"I don't want to rain on your parade.

Hot off the press. The video highlights the recent addition of an SVS AS-EQ1 linear-phase DSP. Now that I've got all the kinks worked out, time to let it rip on camera! [H]
Notes:
Footage was shot over a couple months, hence the seasonal change of goodies on the end table stage left thanks to the girlfriend.
First scene was filmed using a MiniDV cassette and you can clearly hear the tape transport mechanism onboard. Subsequent footage was taken with the camera plugged directly into my laptop (no tape) using Firewire. It reduced the noise floor so much that in the scene with the music from Hybrid, if you listen closely enough, you can hear the motor in the Blu-Ray disc player.
Cheers,

No. 100W is 20dB in terms of SPL at the speakers. With the Fortes hovering around 98 dB @ 1 watt / meter, unless you continuously listen at deafening levels with your speakers properly placed, the combination will be just fine.is this to much power for the forte's rated at 100w RMS?
-
A woofer is bent pretty good in at least spot. There are no useful technical specifications of the components provided. There is no guarantee of their combined performance. I would avoid it, even at $25 + shipping. Checking out the "open stock" at a mass-market electronics retailer is a good place to find deals along these lines- Quiet_Hollow

+ 1Some of us young bucks figured out finances* and acoustics at a fairly young age. Had a very nice 5.1 HT setup in my own place by 19, and got into Klipsch heritage by 25. All is not lost.P.S. - Watch the primary eliminations on American Idol at least once. You'll see, for example, that not every 17-30 year old has good aural taste or tone recognition by default of youth.That my friendis why they have estate sales.
