Thinking of building my own powered sub (1 Viewer)

[Robert_J]

I haven't used them but a few guys at AVS have. Most upgrade their electrical for 220v which improves output considerably.


Since all of these manufacturers rate their amps at 1khz, they will produce that power for that frequency. The lower the frequency, the more an amp struggles to produce rated power and that is true for all pro amps. I look at the RMS power at 1khz and knock about 1/3 off for the 20hz RMS power to be conservative.


On the other hand, no one needs this much power. My EP-2500 doesn't strain at all and I can create scary amounts of sub-bass.

Hey robert I have a question about the behring eq, how do you hook it up to you receiver and then to your power amp? The eq doesnt have RCA or LFE connections. My Onkyo receiver has LFE and RCA style Pre outs, how would I hook all this up?

The RCA plug goes into the receiver. The 1/4" plug goes into the BFD.

ok I know I ask alot of question but is the benringer dsp1100p as good as the 1124p cause i found one pretty cheap. Is there many differences between the two?

 

[Robert_J]

I didn't know the 1100p even existed. The 1124p is only $110. On the other hand, if it is a good deal then the setup procedure should be at least similar. They look identical on the Behringer web site.

I got a behringer dsp1124 last week from a member of this forum. Now just wanna find a deal on a behringer ep2500 and my sub project is complete.

I also thing sealed system is better in terms of accuracy of the note you hear
