Audio classics.com has or makes shipping boxes for McIntosh gear and we recommend getting a special box for shipping these. I have asked them for a quote on the price for each box. See pics on page 1.

Got mine today, too!!!!

That sounds like a protection circuit activating. That amp has more than enough power at 150 watts/ch. It's hard to diagnose from a post, but I'll bet the tweeter protection is saving your tweeters. Turn down the volume. All things have a physical limit. You've found one.

Feed the Sixes with the preamp outs on your A11 or trade it for a preamp only. Keeping the A11 has more flexibility.

None of that sounds off at all. The PrimaLuna should be excellent and it has plenty of power. It sounds like you may have 2 issues. The woofers are new. Woofers really do need some time to loosen up. After I first heard them, I was disappointed in my new Heresy IVs thin sound. So, I ran dub-step with full bass boost through them for about 80 hours (not too loud). Just shut the door. At 40 hours they were much better and probably didn't change after that. Give that a try. You can experiment with using the 4 ohm speaker outputs, too. Older La Scalas ran about 6 ohms in the woofer's range and I expect the new ones do, too. The other is that the La Scala's don't reproduce the lower 5 or 6 bass notes of a double bass/bass guitar very well. Cornwall's will, but also add some distortion that will "fatten" the sound.

How about a nice pair of Belle Klipsch? In Chicago? Or even 3 for a center-fill?

Heresy driver magnets are not that kind of magnet. Sounds like an ignorant decision made without data.

Magnet too strong?! For what? Who, that was qualified, made that statement? How absurd. Probably you should look at FedEx or DHL and just ship them back to Oz.

I'm working on that. There are some pics in a PDF on page 1 of this thread. I just talked to Gil. He said he'd be glad to go with someone to the location where everything is stored and talk "turkey". You'll need to come with a truck or van for the larger stuff and pick him up where he lives. We will pack and ship the smaller stuff, at buyers expense. Contact him at w.f.mcdermott@gmail.com or PM me and I'll give you his phone number.

No speculation whatsoever!

TTT Keeping interest alive so we can generate Christmas money.

Try this question in the 2 Channel section. You'll get answers there. Have a budget in mind for cartridge and turntable.

Gotta have area for the glue to bond. Try calling Eminence to get their advice on restoring your "K-33-Es".

Except that oil prices are lower and interest rates are falling and your wild speculation is way off base.

TTT. I've talked to Gil a few times and he does want to sell his gear to generate some cash. I'll attach the list here after I find it. The 3 matching Belles are the centerpiece, but the rest is interesting, too. If I understand the situation, opus2k9 has passed and his wife is still storing the stuff in her house. We need to get this into new homes to unburden her, too. Gil inventory.xlsx

Line Array? Do you mean stacking? I don't think that would be needed from a performance point of view. Yes, the mouths are small, but a larger mouth or longer horn is apparently not needed to get lower frequency output. These are kinda odd beasts from the way the ports and short horn interact. I can't imagine why you could not parallel 2 or 3 on one sub out connector, whether they had a pass through or not. I use these to parallel 2 sub's on each sub out. Is that what you're asking?

The practical lower limit of a La Scala is about 60 Hz. A, D, C, G is an extremely common bass line sequence in music including acoustic genres like folk, jazz and Bluegrass. That A is about 55 Hz, D is 73, C is 65 and G is 49. E (41 Hz) and F (44 Hz, "Angel Of Harlem") are a!so quite common. "Beseme Mucho" has a 37 Hz D in it. Properly calibrated, a subwoofer will only add the low notes a La Scala cannot reproduce and you will not be able to detect its presence. I would not be satisfied without subwoofers and I am not a bass head. If I can hear a sub, it's 10 dB too loud.

Here is a group of max output response curves for the new subwoofers. However, it requires some interpretation. They were run in 1/2 space and at 2 meters (I'm glad I wasn't Jesse that day!). You should add 6 db for a 1m rating to compare to most other speakers and another 3 to 6 dB for indoor use, depending on placement and room size/shape. You can see the small one can cover any common music note, even Ao, 2 steps below the open B on an 5-string bass.

A naming contest is a fine idea, if the company is willing. Remember, the British held a naming contest for an underwater drone and got Boaty McBoatface!

I recommend you wait and not speculate on things that are unknown and haven't even been discussed at Klipsch. They will have to be competitively priced with other top performing subwoofers. The finishes have been discussed, but are not even final. The final design of the XL is still incomplete.

I like them quite a lot! But they are about 20 years old and on borrowed time. VMPS is long gone and Brian Cheney was notoriously secretive, so no one knows what parts he used. I now have a folder on my computer named "Deep Roy"!

I think the Medium is not as large as you think. If I remove the 4 VMPS Larger Sub's, I'll have plenty of room for 2 mediums in my 17' x 18' x 10' den. I don't think anyone posted a pic of it. It is about the same size as a La Scala bass horn, though about 6" wider on each side. Now, if intense refers to $s, we'll have to wait until this summer. Wanna buy a pair of Acurus A250s? 😉 This pic is a little dark, but the Medium subwoofer is about the same height as one of my subs and 5" wider.

A lot of stuff in these old receivers is no longer available, the output chips in particular.

This is a play around sysyem and I think tubes would be more fun. I looked at the Dayton hybrids. They're interesting. The sound source will be a laptop, so there's no justification for $5000, and no desire in that system.
