Speaker Stacking.

Posted: August 15, 2008 - 10:18am

Hola,

The notion of speaker stacking has always intrigued me. In a way, it's a primitive D'Apollito thing for us dopes who tried it in the 70's before an MTM arrangement actually had a name attached to it.

We're going to use a pair of stacked (the model is a secret for now) speakers for T.H.E. in January, too, so it's been on my mind...

Which lead me to wonder if anyone else plays with this sort of arrangement.

I use a pair of stacked Advents in one system, and used to use a pair of stacked AR 90's before an old girlfriend's cat had his way with them (they are in the garage, waiting to be resurrected.)

I have been looking to maybe get a second pair of La Scalas to try this with. I suspect that may be a synergistic stack.

Anyway, anybody else with some good stacking outcomes?

I used to work with the former Chief Engineer of Dynaco. At the time he was using six Dynaco A25 speakers (10" 2-way) per channel, stacked on their sides, with the woofers on the outside. Although I never heard it, he said it sounded wonderful, very realistic with low distortion at high volume levels.

Yes.

There are some that insist that comb filtering interference will make them unlistenable.

How do you wire that and won't it half the impedance of the speaker?

I'm running two Phase Linear 400 amps, one channel and 8 Ohms per speaker. Many people run them in parallel with a single amp that can handle a 4 Ohm load.

A pic from the moment we got the Advents powered up. They've since come out into the room.

Forgive my ignorance and quick question (I'm new):

Are the doodads in the corner bass traps? Other acoustic treatments? Or what?

Thanks ...

Not at all an ignorant question!

They sure look like smallish bass traps to me.

And Welcome!

Buddha - Where are you going to be at T.H.E.? I had to take some time off from CES but am back on schedule again. It would be great to meet you out there. I LOVE the Alexis Park location....the Venetian setup just stinks.

Anyways....I know Matt Polk has talked about stacking some Polk SDA SRS 1.2 back in the day. It's already an 11 driver beast that stood about 5.2ft tall alone....can't imagine that wall of sound. I've played around with stacking some A/D/S a long time ago and it was neat but not something that lasted. Great pics!

Hola oh wise one,

One of the classics for stacking is the Quad Electrostatic. I was trying to find a picture of Alistair Robertson-Aikman's (head of SME) legendary set-up of stacked Quads driven by Krell MRAs but a quick trawl around didn't turn any up. However I was surprised to find entire websites devoted to Quad stacking!

Hola oh wise one,

In Long Beach CA, in 1975, I listened to a horizontal array of 6 QUAD 57's driven by modded Dynacos. It was rather heavenly!
