Multiple small drivers for large output? - Page 2

anatech · 27th October 2006, 02:02 AM

Hi Curmudgeon,
They didn't have any high, highs either. They just sounded bad. I recall they had a pair of ports and I think a pair of drivers in the rear. Just all the same drivers, no tweeters.

Some people love 'em though.

No XO. 8 drivers to the wall, one toward you.

All 1 ohm drivers wired in series. Nasty electronics to make 'em work.

Cool looking box and groovy stand.

How could they not sell?

Hi All,

First of all, thank you for your responses.

So I guess this is doable. I do not have drivers at hand currently, but was thinking of this type of an implementation. I am not particular about the low freq (will build a separate subwoofer).

If I have drivers 8ohm (or even 4 ohm), and capable of handling 10W output, can I build a system with say 6 of them in series (or parallel) and safely assume this will be capable of handling 60W output?

Thanks
Din

Yes it is doable.

We need more info before we can help. What drivers are you considering?

6 - 8 Ohm speakers: put pairs in series and parallel the 3 "16" Ohm pairs and get 5.3 Ohms - nominal.
6 - 4 Ohm speakers: put 3 in series and put the 2 "12 Ohm" speakers in parallel - get nominal 6 Ohm. Usually ok for most decent amps.

Mount speakers as close together as possible to minimize high frequency comb filtering. For best image and sound stage - I would do vertical stack of 6. Don't expect good bass or treble.

If you use 9 a la Bose 901, then it is a bit more difficult if you don't have 0.9 Ohm drivers - because of the need to use equal power to all 9 drivers. In any case trying to do a Bose is pointless in my opinion. 901s are not good.

This is what I categorically think about "cloning" efforts - Check out this link:

Thanks for you inputs, psych&sound .

I had a look at Bose 901. No I am not planning a "clone" or anything similar to Bose 901.

BTW, real nice video in that link, although I don't remember seeing such an ad on the media here.

Din
