How to Hook Up 4 Dq-10 speakers

I recently acquired a 2nd set of DQ-10s to add into my system of 2 DQ-10s, 2 DQ-1Ws, DQ-LP1, 2 Tandberg Amps plenty of power), 1 Tandberg Controller. I've heard of some who use only 2 amps to do this. I don't know how to hook up my additional 2 DQ10s using only the 2 amps and the electronic crossover; can anyone guide me in this? I see in the crossover manual that it is made to hook up 4 subwoofers with it, but states therein that you need 2 amps just for the subwoofers. Any guidance would be greatly appreciated.

I would be happy to tell you how to use 2 and send the other 2 to my house...if that will help. :) Nice vintage speakers!

I had that set up (Stacked DQ10s/Pair Subs and the Electronic XO)

First you will need "at least" a VERY POWERFUL and VERY STABLE Stereo power amp (or pair of monoblocs) to power just the DQ10's.

That same amp cannot be used for the subs. They will require a separate two channel or monobloc pair to power them.

The DQ10s are 8 ohms and stacking them and running parallel will give your amp a 4 ohm load so they like power, and they like stability (must be stable at 4 ohms and preferably less)

SO to recap:

Each pair of stacked DQ10s will need either a single channel of an amp or a single channel for each DQ10 if you want to biamp the stacked pair.

Each sub will perform best with its "own" channel if you intend to run them stereo. You could run them mono and in get by with a single sub amp if it too was powerful and stable.

I can see how it would get confusing, since there are a lot of options when you begin to consider biamping, stereo/mono subs, etc.

Lots of flexbility here, but one thing for sure, you can't do it all with a single Stereo amp.

Summitav,

Interesting, but how did it sound to you?

If you mean "stacked"; They sounded fantastic!! But that was back in the mid 70's.

System was:

Rabco ST7 TT with straightline tracking
Denon 103 cartridge
Citation 17 Preamp
Dahlquist electronic XO
Pair Bridged Citation 16 amps (for L&R DQ10 Mains)
Citation 16 stereo amp (for Stereo Dahlquist subs)
Stacked and mirror imaged DQ10's for L&R Mains
Stereo Dahlquist Subs.

I hope I remembered that correctly.

I am sure they would sound fantastic today, too.

So can anyone explain why no one tries to stack speakers today?
