That will depend on what net volume and tuning frequency you choose.

ok well i guess ill be going behringer.....so could you tell me whats the best options in running my setup-by that i mean the greatest power output with the lesser of all risks-fi Q's come in D1 & D2 coils and im gonna be running both of the single 2500.
Found the samson pg2200 here for a bit more to your door. UPDATE: I had a second linked company, Musician'sBuy.com, but a BBB check showed sketchy history (and address changes) with the company: advise HTS'ers look it up for yourselves. The first, SamAsh, had an excellent rating.
The pg3800 can be had for $50 more here, which I think may be better suited for you since you're running a pair, I don't know. How much RMS power is optimal for a Fi 18" speaker? (Or the Mal-x? not trying to thread steal) The samson's have a 3 year warranty if they are authorized dealers (I have to check). Anyone ever seen any test results on the samson pg2200 or pg3800?

Re: amp option

i mean..that say the amp runs better on 8ohms per channel for 600watts(just reference..not real specs)..will that be good..so from there i can choose the coils for the Q's-but im going with a 18 cubic ft box and i wanna port around 20-24
i was just looking at the ep 2500 tests on [email protected] 2 ohms/channel-it puts out 819 rms however @ 4ohms/channel the output is 633 rms so i was thinking since 2 ohm kinda pushes the amp to limits and going frorm 633 - 819 rms wont make a difference in spl...whats the point..maybe dual 2's in series per channel is a good idea......do you think the Q's will run well on 633 rms?

Re: amp option

I don't understand. The EP2500 is perfectly stable in 2ohm stereo. "pushing its limits", what do you mean? Every amp is pushed when it's near its capacity, but that doesn't matter as long as it works and doesn't overheat. The EP2500 bridged in 4ohm, or stereo 2ohm doesn't get too hot, it works.

It's designed for that.

Re: amp option

Wiring a pair of D1's for a 4 ohm load would allow you to run the amp in bridged mode which is 2400 watts.

The EP2500 gives at least 2000 watts continous in 4ohm bridged mode, see this:

(bridged here: http://www.avsforum.com/avs-vb/showt...5#post10755565)

Notice the distorsion, it's very low. You get more watts, but at higher distorsion.

Re: amp option

Actually it's more like 825w per channel into 2ohms and an estimated 1650w at 4 ohm bridged as tested in the link above. We are talking about bass here. 1khz is a field day for any amp. Look at the 20hz results. It kept popping fuses when the 4ohm bridge test was tried. BTW this is not a bad showing for it. It should be quite a bit better when actual program material is used.

That's true , sinus waves puts the maximum amount of pressure on the amps, it's nowhere near program material as you say.

And still a great showing for the amp that sells for so cheap.
