Subwoofer using multiple smaller drivers

goldyrathore · 6th February 2009, 02:39 PM

Can someone please point me to subwoofers ( DIY or commercial) made using multiple smaller drivers (5.25" - 6.5")?

The idea of using multiple smaller drivers has always appealed to me and I remember at least one such company carrying a sub in their portfolio but am unable to find it.

Thanks in advance,
Goldy

What is your reasoning behind this? You will get better results by using one big driver, as for the same money lots of small drivers will be cheap ones, against one really good quality big one. Also the small drivers will most likely have lower resonance frequency so need (more) equalisation.

Hi Richie00boy

The reasons are many

1) Its for a line array where the mids start from 500hz. A bigger driver will not be able to go that high.

2) I assume that eq may be used to bring in the desired low end response. 4 (or even 6) 6.5" woofers per side in a stereo setup can take ample power and have quite decent excursion. I am aware that both of these are required in plenty if eq is used.

3)I donot have access to good quality big drivers, whereas mid woofers like wavecor are easily available.

I am looking at existing designs to see how they fare. With room gain I intend to have F3 of 25hz in room response.

Tangband's 6" sub might work

I was about to tell you to look at the 6" subs from DLS for car audio, but then noticed you wish to run them up to 500Hz. Quite high for a subwoofer

I'd suggest rethinking the lower cutoff and going for ~50Hz with a 24dB high pass, and then using a 'conventional' 12" or 15" subwoofer for the bottom end. This allows you a much larger choice of bass drivers and gives you some headroom in your design.
