  1. How do you get those cool double posts? smile.gif

    John Warren,

    I don't disagree with your assessment of the Heritage line. However, a Wilson WAMM is more expensive than my house. The point is most items are an engineering trade-off between price and performance. I and most of us here have decided the Heritage Line is the best price/performance trade-off in the audio world. I have some ability to modify my La Scalas for better performance. I'm intrigued by djk's suggestion of the Comminity M200 as I had discovered it independantly and thought it might be a good substitute. However, I draw a line at sawing off the K-400 and using bondo to fill the crack (perhaps he omitted the TIG weld). Perhaps if Klipsch produced a horn that would readily accept the M200, I'd be all over it. Until than, ....

  2. I sent you a response curve of a La Scala vs. a K-horn; both were measured in a corner. The Belle will be similar to the La Scala.

    The La Scala uses all of the K-horn components. The Belle's bass horn is wider and shallower than the La Scala so, it has a shorter squawker horn to fit into the shallower cabinet. Those are the two major differences in the Belle vs. the other two. It is said this causes no audible difference. The Belle is easier to place in the room, but takes up usable floorspace, unlike the K-horn.

    I use 2 VMPS Larger Subwoofers below 60 Hz with my La Scalas and am very satisfied. I'd buy the Belles if you don't have open, solid corners at each end of your long wall. Listen to them for about 3 months and then if you're not satisfied, go looking for a high output, low distortion subwoofer. The VMPS New Larger Subwoofer has an attractive finish and fits the bill, but is unpowered. Klipsch has a new powered sub, the RSW-15, that will work well, too.

  3. I have a Sony DVP-S3000 DVD player. I selected it because it has 2 seperate lasers; one optimised for DVD and one optimised for CD. It was built before the DTS standard was set. Such are the risks of the early adopter. It will pass DTS if it is all that's on the disc. Otherwise it will pass anything BUT DTS. Sony says it can't be modified.

    I'm thinking about another *cheap* DTS capable DVD player for DTS only. If I take the digital out to my pre/pro and let it do the decoding, will I lose sound quality? DTS is all about quality and I want that, but I can't see plopping down the big bux for a transport until DVD-A and SACD are settled.

  4. A voltage is positive or negative with respect to a reference point, like positive and negative temperatures. It your reference point is 100V (black lead) and the test point is 80V, you'll read -20V. It's a relative thing and can be used to show the direction of moving electrons

  5. UPS won't let you open a C.O.D. box. However, there is a solution. I use iescrow.com. I give them the money, you ship me the stuff. I get 3 days to test the stuff and they then release the money automatically. If during the 3 days I find a problem an e-mail stops payment, but I can't get my money back until you get your stuff back. Tracking numbers establish the location of the goods at any time.

  6. There's a lot of stuff I can't hear or can't hear easily in the room I use. However, I have seen the Dope from Hope introducing the solder terminal -V and it's response curves. The latest -V is obviously smoother than the previous one and has better output from 4k - 6k. That's why I went to the trouble to find a second solder-terminal driver. I expected to hear something, but didn't. Maybe if I had 2 of each and swapped both at once, I'd hear it.

    Why does Klipsch use such a small throat in the K-400? When I first saw it I thought it looked too small, but I barely understand the physics. Is the small throat a way of getting a horn with a 263 Hz cut-off in the space alotted? If the throat were larger and the length the same (with a small increase in mouth size, perhaps) would the cut-off rise to an unacceptable frequency? Specifically, what does the small throat do to sound (velocity too high?)?

  7. Those ARE the late drivers. I have 2 of those and one of the early K-55-Vs. I can't hear a difference other than the fact that the newest late driver has less output than its twin. I have had the disphragm replaced and found the voice coil was rubbing apparently from abuse.

  8. The factory is good sized, but not huge. The warehouse is stacked to the rafters with new product, even the Heritage Series. The atmosphere is casual and comfortable. QA/QC is turned up very high; miniscule dimples I couldn't see cause cabinets to be destroyed. The people at the factory were very friendly, helpful and eager to help me with a pair of grilles I bought. The people there are excellent hosts, but make no mistake, their passion is fine horn speakers and they take that very seriously.

  9. I can't say if the corssover will work, but the K-400 is too long to fit in a Heresy; it and a K-55-V is just short of 24" long. There is a difference in the K-55-V and the -M. The -M is a little more efficient and sounds different. For years Heresies had K-55-Vs on K-700 metal horns. You might want to go that way.

  10. The input impedance for the sub will be so high there will be no power loss to your La Scalas.

    In order to have a chance of keeping up with your La Scalas, you need the biggest sub you can find. I would not consider less than a 15". I have 2 HUGE subs, 42" tall x 21" square made by VMPS. They have a 12" driver, a 15" driver and a slot-loaded 15" passive radiator that's tunable. They are 12 dB less efficient than La Scalas. Both are in the corners and are powered by an amp that can put out 450 watts per channel. It is rumored NASA used several of these for sonic boom testing (VMPS claims NASA as a customer). They will barely keep up when I crank the La Scalas.

    Both together can do about what one Klipsch RSW-15 can do on 1700 watts peak.

    If you want deep bass when cranked, you need all the sub you can afford.

  11. I'm not sure what you're thinking with "a more modern sound". Speakers are accurate or not. I'm biased because I have 4 La Scalas, but I think they are far better speakers than the RF-3s. Why don't you spend your $1000 on a good powered subwoofer. It will get its input from the speaker outs of your receiver. I normally use the second pair of speaker terminals to "signal" the powered sub and that way I can easily turn the sub off if I want (A+B is normal, A is no sub).

  12. I've got 3 of those hand-woven, garden hose, CAT-5 speaker wires. I did them myself and probably have no more than $50 in them, plus sore fingers and a wife that thinks in certifiable! They improved the detail or clarity on my KLF-C7 a little and did nothing for my La Scalas. My theory is the relative reduction in DCR vs speaker impedance is at work. The La Scalas are 32+ ohms in the midrange, where differences are easy to hear; 1 ohm less in the cable in not much overall change. If the -C7 has a typical impedance curve, 1 ohm less in the cable vs. 7 or 8 in the midrange is a lot of relative change.

    I have always been a doubting Thomas and continue to be one, but I have some fairly expensive Vampire Wire interconnects because I heard the difference and I liked it. It could be nothing more than better mating of the preamp to the power amp, but it works for me.

    I don't believe there is anything but $$$ mojo in the truely high-end.
