I'd be interested in hearing about your impressions when you audition them at home.

Space: Check your other post where you asked about the serial numbers.

J = 1971 KB = Klipschorn "B" style (with the riser between the top and bottom section) MR = ? (possibly "Rare African Mahogony") Are these the ones in the local paper?

Since we're talking tube preamps here, any comments on the units from BAT?

My La Scalas look identical to Killerbees. My label has faded, so I can't read what type it is.

Very Nice! Great work Q-Man!! The Khorn/LS perspective is interesting. What it doesn't show however, is that if you have the corners for them, Khorns are actually easier to integrate into a room. Believe it or not, they take up less space than La Scalas, and probably also less than Cornwalls. It's great how you can tuck such a big speaker in the corner, and not lose that much floor space.

Your La Scalas actually look like they came with the front grill, and the previous owner simply removed the grill cloth and applied a finish (could be the reason there is no logo). The older La Scalas that came with a grill from the factory have that exact same type of trim. My La Scalas, which have the grill look identical (except mine still have the grill cloth).

Dave: I was just adding a little exageration onto that wall dimension. However, I would have guestimated it was slightly more than 21'. 24-25' does seem about right. By the way, your Khorns sure looked big. What were they, about 8' tall or so???

Dave, Are you sure you measured that wall correctly. I seem to remember it being at least 35-40 feet.

I have used a Pathfinder (1992) to transport Khorns in the past. Fold the rear seats down and you can fit exactly one (1) Khorn in the back. It is a tight fit, but a single Khorn will fit in the back. There is no way to fit two Khorns in a Pathfinder (unless it's a convertible)! Rent the covered trailer and bring plenty of old blankets with you.

Sorry to hear about this. I hope everything turns out well.

I hope everything turns out well and that you're able to get back to enjoying Klipsch speakers very soon.

I'm not sure I understand what you mean by "pipe resonances". Can you explain?

The advantage with tube subs, is that the tube portion of the enclosure (not the endcaps) will not resonate like a flat surface will. With a flat surface (i.e. box speaker), the material will actually flex. In a tube design, the only way the material in the circular portion of the enclosure will actually move, is if the material itself stretches. This is not going to happen at the pressure levels were talking about in a subwoofer. Of course the endcaps are flat, so there is potentional for some flex on those surfaces, but overall you're goint to get much less resonance with a tube than with a box. This is the benefit a tube has over a box.

Unless the PASSIVE radiator is actualy ACTIVE, the PASSIVE radiator will displace exactly the same amount of air as the active driver -- no more, no less. Physics dictates this. This is true for every single passive radiator.

quote: Originally posted by m00n: I want to push the speakers to the limit without blowing them. Do you really have a good reason for trying to do this? If you really try to push your speakers/amp to the very threshold of damage, INEVITABLY, you are going to cross that line. If you do try this test, not only will you likely end up damaging your speakers, but you may potentially end up damaging your hearing as well. I don't see what you are going to get out of this. I strongly suggest that you rethink doing this. It is not a good idea.

Thanks dndphishin, very good feedback. It seems like I will want to get some eq as well. I haven't decided how I'm going to power them yet, but I've got some time to work that out. I also know that if needed, there should be some tweaks that can make them go even lower. I'll have to investigate that as I get closer. However, I may decide it's not even necessary. We'll see.

Thanks for the thorough review dndphishin. In regards to the "down side" of these speakers, do you notice their lack of deep bass? I realize these things won't go as low as a true sub, but my gut feeling has been that they will go low enough, and will probably be adequate for my tastes (the reason I finally decided to get them). Maybe it's just me, but I really don't care to get bass so low you can only feel it, but not hear it. I have already received mine, but won't be able to put them to use for a while, so I am still interested in hearing about other's opinions such as the review you provided.

Congratulations Dave. I'm sure you'll be very happy with your purchase.

Barista: I too would love to see something like this happen in the DFW area. There are quite a few on this board that live here. EQ Shadimar held a session at his place a few months ago and a few members showed up. I was unable to attend.

Keith: Apparently I misunderstood what you were saying. Sorry.
