Subwoofers for music- paired not single- recommendations and advice?

[Mr.Ian]

Wjilst you are waiting on cash would download REW and have a play with it. Firstly you can input your listening room dimensions, speaker positions, subwoofer positions and listening spot and it will generate a theoretical frequency. From my experience its pretty accurate. Changing the parameters should give a you good start on what to expect with your speakers and subs in range of different positions.

as for integrating the subs, that is a huge challenge and one that I am not sure I every totally solved.

Using an external crossover and manually equalising the subs digitally gave me a flat response in room down to 15hz but it never sounded that great. Using a DSP dualcore and equalising as 2.2 gave the best sounding results but it came with back ground hiss - I have read minidsp can be the same.

In the end I gave up and put the subs on my av processor and leave the mains to drop off from 40hz.

I am tempted to try again, next time it will be with small (min 10" driver) subs close to the speakers, wired via the high level inputs. EQ wise I am going to stick with REW and manually tweaking response and decay via an analogue parametric equaliser.

It might not be perfect but it should avoid the ADC + DAC conversion and the hiss, then again if a DSpeaker X4 came up at a bargain price....

Hi,

BK electronics do a nice range of affordable subwoofers that i can recommend: http://www.bkelec.com/index.htm (If you can get past the 2002 looking webpage).

They will make modification to the filter circuit if you need it (they changed the low pass frequency and attenuation curve for me).

Do you know the low frequency limit/ modes of your room?
