Advents were cheap and the sum was 3 times the peformance of a single pair. Everyone had advents and so did your buddy, instant stacked advents.
Others speakers have varying degrees of improvement.
Naysayers will talk about comb filtering. It is a thing that decreases the overall performance of the Double Advent Loudspeaker System.
Try it if you have the speakers (SD 10s) available. No reason not to if wired so your amp can drive em. I don't know the impedance of those speakers.

As to why this particular speaker: many have traced the Stacked Advent to a reviewer, I believe from a magazine, who stated something to the effect that stacking the Advents eliminated some of the Advent's faults and elevated them to a very high end capability. Some have suggested the distance between the woofers on the stacked Advents caused this effect; if this is the case the effect for the OLA's and NLA's would be different as their woofers are located differently in the baffles. I would be surprised if no one eventually chimes in with the names of the reviewer and the magazine and a link to the review. (I have the information somewhere, I just can't find it)

Back in the early 1980s i ran stacked Daisy chained Klipsch Cornwalls for fronts and stacked Daisy chained Klipsch Heresy rears in my quad system for quite a few years with spectacular results ,only I stacked the top pairs right side up ,stacking the top pairs upside down presented bloated mids & schreeching highs with 8 mid horns and 8 tweeter horns at ear level ,having the woofers at ear level was alot of fun with insanely high SPL from the system.

Here is a copy of The Absolute Sound article about stacking advents: http://www.classicspeakerpages.net/...s-as-reviewed-by-the-absolute-sound-magazine/

Stacked Advents powered by a PL700 even! Wow ... Those guys let their hair down back then I guess.
My buddy Mike had three pair stacked for a bit - all on their sides. He swore by it.

I’ve heard stacked inverted DQ10’s, pretty dang good too.

That must be quite a balancing act
(actually I assume they build some sort of frame)

Uhhhh....
I've stacked two pairs of Marantz Imperial Sixes. That was quite a "wall of sound", and lotsa fun while watching Star Wars.

Yes there was a very well integrated frame, kind of a test mule. A good friend has some stacked OLA’s on specifically built risers he’s running off a Sansui 8 that sounds great.
Another good friend and fellow AK’er stacked two mirrored pairs of Dynaco A25’s that are fun to listen too.

Harry also blew several tweeters with that configuration. Which may be why the later New Advent tweeter was ferrofluid cooled. He also tried triples with two side-by-side with the third inverted centered between the two.
Years ago, he visited Atlanta when I still lived there and heard my doubles of the New flavor. He wondered how they would sound in a modern cabinet eliminating the diffraction. In my current garage, I used to run doubles but use singles now as they image better. I mitigated diffraction by running them sans grill using felt furniture pads around the tweeters. And drive them safely with a 300 watt/channel amp.
