Dahlquist DQ-10


The Phased Array model DQ-10 is a five-way dynamic loudspeaker system.

It's operation is based on patented acoustical techniques which provide very accurate reproduction of source material.

In order to minimize undesirable effects from diffraction, each driver has been separately mounted on the smallest possible baffle, whose dimensions were determined by the frequency range of the passband.

This is directly opposed to the standard practice of mounting the drivers on one relatively large baffle.

The mounting method used in the Phased Array also makes it possible to incorporate time-delay correction through relative front-to-back positioning of each element.

Tremendous quality in a mid 70s speaker. I have the original ( not mirrored and not modified) version. Jazz is especially well appreciated with this set.

Mirrored pair. Forget nonsense about the power needs of these speakers. Mine are well driven by a 50 watt tube amp AND they are on the floor AND close to walls and they sound amazing.

I completely refurbished my pair of DQ-10's that I bought in 1977. Marketed as Phased Array, this is the most accurate & neutral speakers I have in my collection.



re: DQ-10

The chain: Teksonor CD 9 is the turntable, pre Cabre Stradivari, biamplification with pa. Cabre 102 and 202 (mono coupled) crossover Cabre 105.
The DQ 10 with DQ1 sub sound terrific!
The amplification and the turntable are really great.
I will not change them anymore!

re: DQ-10

I was thinking I was going to mirror image mine but then I realized that the non-mirrored image original. Does the subwoofer make a big difference? I don't have one but considering buying one

re: DQ-10

I reformed the woofers, rebuilt the crossovers with new caps and wire, rebuilt the stands and they sound fantastic! Powered by a 160 wpc Rotel power amp, but I have also used a Rotel integrated with good results. If you like to listen at elevated levels, you will need 100 wpc. Very clean and open sound at all levels, if you can find a pair in good shape I would recommend these as a top choice. If you want a project, these can be found in need of repair quite cheaply, and the repairs are quite simple to perform.
