I'm selling these for a friend. It is two pairs of Dahlquist DQ-10's in a D'Appolito configuration. All the speakers are rebuilt, and the configuration is physically assembled very well; super sturdy. He made custom grills that velcro to the speakers.
The price is $1600 OBO

Does stacking speakers like this sound better than a single set of the same speakers properly set up in the room? I've never heard stacked speakers, some am asking for feedback from those that have......not the normal peanut gallery. :'(

2....2...2 nuts in 1.......

Yes they do. The key is the D'Appolito effect. some manufacturers build this into their designs.

I'm sure they sound amazing... but that it THE single craziest spesaker I've ever seem.... the Jackson Pollack-Rube Goldberg-Heironymos Bosch speaker!

@bmwr75, the D'Appolito configuration is actually really common. I think all Acoustic Zen speakers feature a D'Appolito configuration. I won't pretend to know technically what it does, but I feel like these image way better than just a pair of DQ-10's, and they obviously get more volume.
@RuralTom, yeah, they're a little nuts looking haha. I think he built the grills so his wife would let him keep them. If you crack the grill off a DQ-10, that's what it looks like too. They definitely didn't try to make them pretty haha, but I guess that's what grills are for.

It is all good, BJ, again... I bet they sound spectacular! I wish I could hear everybody's rig here, all the permutations.

I wanna know what yer 'secret speakers' are.....

FYI... In many Pro Sound applications they also do this set up... Having the tweeters "stacked" in the middle... (aka - placing one speaker on another) I'm guessing they would sound great! Sorry, too big for my use and too $$$ also! :)
Hope you sell soon...

This brings back fond memories of two stacked systems I ran back in the day as they say. First were stacked large Advents (tweeter to tweeter) and then stacked Mac XR-5's. I was certainly not the first or only person to stack Advents, in fact the dealer might have demo'd them that way in the store. The Macs were designed with stacking in mind and could be partially disassembled and put back together as a single system of two or even three pairs.
The stacked systems always sounded better to me. The upper systems eliminated low frequency floor bounce, power handling increased and SPL went up (as previously noted). Image suffered a bit with the Macs, but image wasn't their strength anyway.

Excellent work BearJew. My cousin Geary did the same setup with his DQ-10's, per the knowledge spilled upon him from Tom(OCCD).
His Dahlquist setup,along with the combination of Audio Research and Sunfire gear sure is impressive. You should have no problem getting that price for your speakers BearJew, simply because they're worth it.
The question that I would like to ask you is, should you even be selling them in the first place ? ???
All My Best, Bill

The guy that owns them upgraded to new speakers and asked me to help him sell these. I think he's just trying to keep a balance on the money end; he just bought two new sets of speakers.

Ah! Stacked Advents, the original lease breaker!
Stacked speakers had a way of sounding better. Even if the speakers were not identical, or not great speakers to begin with. I think that is what made stacking popular is that you got a fuller, dynamic sound. Image was not great as you noted. For some people image don't matter. I'm personally not in that camp.

I think speaker technology has advanced considerably since "back in the day" (my memories go back well over 30 years) and stacking no longer offers the benefits described when compared to modern speaker designs. It does occur to me that stacking emulated the notion of a line source array, if the stack was tall enough. It may also be that we simply had a ton of fun cranking tunes and consuming who knows what to excess-that bigger and louder was better.
I sure wouldn't mind trying stacked Advents again, even if only for a weekend and if for no other reason than to learn if they really sounded as good as I recall. I do agree that my current system images far better (and has lower distortion, wider frequency response and more powerful dynamic range, etc.)

When I worked at Let's Make Music I got to hear alot of high-end speakers but one day I listened to a pair of original Large Advents I just repaired and was surprised at how full and natural they sounded compared to all the new speakers.
The old Advents lacked the sparkle of detail in the highs new speakers had but they made up for it by sounding warmer and fuller.
New speakers just seemed to be lacking bottom end.

MG Most new speakers are designed stacked with the drivers. It is viable for older speakers. Any speaker design that has midwoofers over and under a tweeter counts. Most speakers are designed that way now. It gives new prospective on older speakers. I did the over under large advents before and the result was incredible
-
I'll be the odd man out.....my experience with stacked speakers is no good. Sure they play louder. But its nothing more than a huge wall of disconnected sound. I' ve stacked klh, advents, several diy, even mixed and matched sets. In every case the soundstage was blown to hell.
there was an odd balance to the sound. It was no longer a pin point source but more of a big, fat, incohesive blend of sources.
Sorry..but yuk.
-
at, you don't have to be the odd man out. I'm a loved of single point coaxial speakers, so, OTOH, the idea of that many drivers doesn't appeal to me. OTOH, I see the benefit of the configuration as being similar to the benefit of coaxial. Almost as if the woofer on the top and bottom are creating one huge woofer with the stacked tweeters being the center high frequency point.
That said, it's all just theory because I've never owned four of the same speaker to try stacking them.
-
I think a lot of it just comes down to preference. Obviously the configuration provides a different sound, but whether or not is bed is more or less up to you. What little experience I do have with D'Appolito's sounded really good, and I was actually really close to pulling the trigger on Acoustic Zen Adagios, which (like most AZ speakers) utilizes a D'Appolito configuration. I went another direction for reasons yet to be declared, but they're supposed to be brilliant speakers. I know that Celestion made speakers like mine but with a D'Appolito configuration too. I do know that these DQ-10's sound really good though, and based on all the work that went into making them sound this good, they're easily worth the price.

Bearjew...I'm sorry. I didn't mean to imply these particular speakers sound bad. I've read that the DQ10s stack nicely. As you mentioned it is a personal preference. I myself just don't click with stacked speakers. Back to your friends sale....he might consider unstacking them and selling them on eBay. In typical eBay fashion the final price is all over the place but I saw one set over 800 dollars. Try Audiogon too. I remember first hearing them. They made a huge impression on me. As a matter of fact the two most lasting impressions I have from any speakers are the DQ-10s and the Spica TC-50....you wanna know why? They are both phase correct, time aligned speakers. Nearly every speaker I've owned since then have been time aligned, phase correct speakers. That's an area I am sensitive too and why stacked speakers don't click for me.
That's another soap box for another day. Best of luck with the sale.
