As I understand it a sub woofer, by definition produces subsonic sound, i.e. lower frequency sound than the human ear can hear.
No, that's wrong. You can hear 20 to 40 Hz.
I'm mainly interested in music (which to me does not include the Eagles) So, if all we are talking about is vibration, I can live without it.Okay, church organs then. Or Jazz from Holly Cole. There's lot of music with low frequency content. Don't be a snob about it.

What is "DACS"?
DACs? Digital/Analog Converters.
I'm surprised you are having such a hard time. The speakers are set to "large" right? (I know it's a stupid question). My La Scala's sound great to me on a mid-fi harman/kardon avr 325. But I've not found of any fake surround modes. I listen to plain stereo for CDs and only use the rear speakers on music for DD or DTS encoded sources (no SACD or DVDA yet as my older DVD player doesn't output them).

Sorry... And I thought I was on to something.

I think it would probably take a pretty hefty subwoofer to beat the bass response of the Cornwalls.
It's surprising what a sub can do.
Play "Finding Nemo" chapter 25 where the little girl Darla taps the aquarium. Does your house shake?
Play The Eagles "hell Freezes Over" DVD in DTS. Does the kick drum hit you in the chest?
Cornwall I's do 38Hz-20kHz±5dB, which is a bit lower than my La Scala's 45 Hz but it's still high compared to a sub. There's lot of sound below 40 Hz in movie track (and even on more music). I added a Hsu STF-3 sub (-2 dB at 25 Hz) to my system and it really adds depth to 2-channel music. As far as movies, it's a new experience altogether. I set my fronts to Large on the receiver so they get the full frequency spectrum, set my sub to crossover to 80 Hz and send all materiel below 80 Hz to both the fronts and the sub (LFE + L/R). Sounds great to me.

It's got to be a store. Why else would the pictures be blurry, e.g. hurried. If you lived there, you'd have all the time in the world to take great pictures.

Found it!

Sorry I didn't think to tell you either. I just now made the connection that you needed something like this.

If you have been following this thread, you may remember that I have been trying to figure out a quick way to mount the woofer from the front. Here is what I have worked out to try. There are 4 10-32 drive in inserts installed from the front. The hole for the inserts extends all the way through the motor board so that 10-32 X 2 inch screws can be installed from the back through the inserts. Then some metal plates are installed and held in place with wing nuts. The strap across the bottom of the woofer gives a lip to hold the woofer in place until the wing nuts are tightened. I still have to get some small springs to go under the 4 metal plates that will hold them forward against the wing nuts to position them out of the way (turned sideways) to ease installation.
Bob, there was a subwoofer thread recently in which a URL was provided to a sub built under the HT room (in the basement). The sub consisted of many 15" woofers and they were held in the hole using a similar arrangement, but using C-shape d pipe holders. I should find the link because my explaination sucks. But I think it would work.

I have a product catalog from the Canadian distributor dating from ca 1980. The catalog has both my Klipsch and Nikko Alpha 220 power amplifier, which reminded me how I was introduced to Klipsch: The store where I got my amplifier had Klipschorns, La scala's, cornwall's and Heresys in the same room!
Anyway, the catalog has two pages on Klipsch, including the mcm 1900 (huge thing with 2 15" drivers yielding 124 dB at 3 meters outdoors), La Scala Industrial and Heresy Industrial (looks like a stage monitor). The specs on the La scala are numerous, but i'll summarize with:
SPL 96 dB at 1W and 3 meters (Note this is much further away than the typical 1 m)
SPL 119 dB at full power (200W) at 3 meters.
Frequency response:
42 Hz -- 17000 Hz +/- 5 dB measured indoors
60 Hz -- 17000 Hz +/- 5 dB measured outdoors at 10 meters, 1 meter above ground level.
Drive components:
Woofer: 15" K-43
Midrange: 0.7" K-55 (K-400 horn)
Tweeter: K-77 horn tweeter
Hope this helps. I could scan the pages and email them to you if you want.

Well, the look-a-like thread I started a while back lead to a long-ago reply from PWK himself. And I wasn't even aware this was already issue 30 years ago. I guess that problem is here to stay.
I for one won't be saving a few bucks to get the cheap imitation. The initial temptation to save a few dollars is gone. I'd rather buy used than do that.
Thanks for the post Trey! It was indeed informative. I'm not sure I would have removed the initial thread though. I think it's good to leave a google trace for potential buyers of the look-a-likes to find so they can be better informed.

The bottom right cabinet will have a half width 15 bottle U-line wine fridge. I could put a half width fridge in the left side, but I don't know if I want to, seeing as the kitch fridge is 30 feet away.I'll have to reevaluate the situation after I get some use out of it.David
Sweet David! I was half-kidding you know!
That's a very nice looking setup you have there, congratulations!
-
Well, that's some more incentive for me to get my 31 year-old LS crossovers in BEC's hand...
-
Ok, last one. One more picture of the dry bar.David
That dry bar needs... refrigeration!
Add that to your list of future upgrades! (Although that would be noisy...)

I don't care about the physics involved (so far all of it posted is correct).Put 30 feet of wire on your left channel and 5 feet of the same wire on your right channel.After doing this, please try to tell me that you did not have to adjust the balance control ever so slightly toward the left to get the image in the middle...Physics is great but we must all be good observers as well...
And you're not kidding? You have to touch the balance control for 25 feet of wire? Then replace that 28 AWG and put in some 12 or even 14 AWG.

Even if I don’t totally agree, that is what is in all the literature and I don't have a better number so I used it.Second, yes we are saying different things. DM is saying that a -3db difference in SPL represents a 1/10 the power going into the speaker. I am contending that the db measurements in SPL and wattage work the same or that a 3db reduction in the SPL is produced buy a 3db wattage decrease. Putting it another way, I am saying the relationship between the wattage going to the speaker and the resultant SPL is linear while DM is saying it is logarithmic.DM, in case you would like to look it up -- third paragraph, first sentence.
----------------
Hmmm. I thought that when he was saying "It's -10x the power, 1/2 the loudness from the reference (0db)." he was refering to your "-10db is usually considered half as loud.". Those statement would be the same.
The dB scale is for sound, and thus you can't technically say 3dB more Watts even though we all understand what that means. That might be the source of the misunderstanding?

It's -10x the power, 1/2 the loudness from the reference (0db).DM
----------------
DM, you are not saying anything different from Scriven. He is correct. A 10 dB difference is ten times the power, consequently a 3 dB difference is double the power. A 10 dB SPL difference is considered to be a factor of 2 in loudness, but it always seemd bigger than that to me.

No prices?
I'm not really in the market, but I see so few La Scalas in Canada, and I do need a center speaker... Maybe my brother would be interested too.
-
Wow. I'm glad I asked!
I'll decide soon enough, but I will do something. :-)

I haven't decided what to do yet, mostly because of all the good options people have given.
The current crossovers are AA.
A likely scenario will be either shipping them to Bob for inspection and fix-up. It would be good to know the sonic differences between Dean's and ALK's crossovers. I'm using an h/k 325; not high-end tubes.

There's no way I'm putting a La Scala over my 52" TV. That would look silly. Even a pair of Heresy's will look silly when I eventually gather the funds and find some close to me (next to impossible in this part of Canada).

It would be reasonable to mention other brands in threads, but perhaps not to begin a new one with a non-Klipsch topic such as
Help me decide which SVS sub to buy!
Right?
BTW, I agree that Klipsch needs a heritage center speaker!

S'lut l'oreille,
Ben manque que j'comprends ca. J'ai du La Scala pis j'm ben ca aussi.

If you put 4 volts across a 20 Ohm resistor, 0.2 amps will go through it.
How do you plan to limit it to 3 or 4 mA?

I like my h/k avr-325 on my La Scala's, and I got it at a reduced price since it's a 2003 model. It's heavier (at 40 lbs) than the newer units, which can't be bad. Has an OSD. It has 7.1 and I also only use 5.1, but I can always say that the extra 2 are really my unused zone II rather than my unused 7.1.
