I mirror imaged one of the 1st pairs of these we had thru the store (even before the idea was mentioned anywhere). You'll need to flip the midbass baffle to keep the piezo in the right place. The backsides of the array also benefit from liberal use of ductseal.

The bass units are offset (both the same way) so major surgery would be required to completely mirror image them or is it completely neccessary.

Old timer war stories. My reaction to the DQ10 was the same. The only other speakers which came close were big Maggies, the Acoustat X and the Snell Type A.

Dahlquist DQ-10 loudspeaker
By J. Gordon Holt • January, 1977

The Dalhquist DQ-10 loudspeaker has not as yet been formally submitted for review. (The designer tells us he is still working on the low end.) We auditioned a pair at the one local dealer we could find who had the DQ-10s on demo, and were immensely impressed. Obviously, Jon Dahlquist is on to something that other speaker designers have been overlooking, for, despite the multiplicity of driver speakers in the system, the DQ-10 sounds like one big speaker. There is no awareness of crossovers or separate drivers (except at the low end, about which more subsequently), and the overall sound has a degree of focus and coherence that is surpassed only by the Quad full-range electrostatic, which don't go as low at the bottom or as far out at the top.

Any criticisms? Mainly about the low end which, although well-balanced with the rest of the range, seemed somehow unrelated to it. Bass was a bit loose and flabby—which the upper range was not. The designer is acutely aware of this, and has been working to improve the bottom—here we go again!—which is why, we are told, we have not yet received our own samples for testing. Even as it stands now, though, the Dahlquist DQ-10 is near the very top in its price class, and is stiff competition for the no-holds-barred (and cost-no-object) Class A "Recommended" speaker systems.

In our opinion, the Quad still does a tiny bit better what the Dahlquist does extremely well, but the Quad is a very difficult load for many amplifiers, and won't put out anywhere near the sheer volume of of the Dahiquist. A tough choice.

Me says:
DIPOLE BASS MAN! THAT IS WHAT HE WAS LOOKING FOR. GO CLONE!

Bass unit isn't as critical...we just left it as is. A new baffle would allow mirror imaging (or a new bass cabinet)

That reminds me that Dalquist was using a Large Advent woofer... useful to know if you need woofers.

Its the same thing. You just flip the mirrored channels. If sidewalls are too near in your room, you position the speakers with the domes to the inside, so to moderate early side reflections.

Here's a mirror-imaged pair (improperly refoamed) taken from the Dahlquist Yahoo! Group:

More information can be found there including the original patent, crossover schematics, owner's manuals, pictures, owner's discussions and so on.
