Design Acoustics DA-20 sub: specs?

Hi all,

I found a Design Acoustics DA-20 sub (sadly without matching DA-10s). Cosmetically rough but it looks like it's been refoamed at some point. I could easily refinish the wood and reskin with new cloth and it would look like new.

I can't seem to find any specs at all on this unit, e.g. what was the crossover optimized for, safe power input, etc..

It works fine in a non-biamp configuration with an old Marantz 2015 and a pair of Polk RM satellite speakers I have laying around, but they don't seem like a good match for the subs crossover (or maybe they are just too bright for the old 2015).

(Also I note that it seems to be designed for use on carpet, testing on my workshop floor (painted cement) resulted in some travel. It's apparently got a tilt to the left...)

Da-10??

Was there a model DA-10 or were the PS-10 meant to be used with the sub??

the PS-10 were the square cabs with the mid/tweet on the front and the 10" woofer on the bottom.
 
You should see if the yahoo Design Acoustics group is still active, those guys would know.
 
Thanks for the reply.

On the DA-20, the connectors say "output to DA-10", and searching the threads here I read references to this setup as a DA-30, e.g. -

So, It looks like the DA-10 were small bookshelf sized units, and well made to boot.

I moved the sub to my basement office area and have connected it to the same Polks and a little Teac CD/receiver (roughtly 15-20 watts capable) and it seems to drive the sub pretty loud before the amplifier itself runs out of breath (I don't push the old Marantz as it still has all it's original caps). At normal listening levels its pleasant enough, but for certain the Polks are a mismatch in being too bright, I suppose they are a bit more efficient.
 
Ha! It needs current, more than the dinky Teac tabletop unit can deliver.

I pulled a Sherwood Newcastle R-525 out of the dustbin and it's much better now.
