DD DMF2800 or T2500-1BDCP

[speedyjuarez Premium Member]

I'm looking to buy me a new amp something that can do 2k at 2 ohms for 4th order bandpass subs.

DMF2800 - 400 price tag, I can't find any reviews on this amp and not sure if this does rated power.

T2500 - 1400 price tag, good reviews and does rated.

I like the price tag of the DMF 2800 but I'm not sure on the quality. What other amps should I be looking at?

Thanks

Holy shlt, 1.4k for 2500 watts?! Rockford really has some brass balls.

its overpriced but it does 3k at 2 and 4ohm. most 6kw don't do 2.5kw @ 2ohm 12.8 volts

not even in the same league as far as you can tell. the RF is way stronger and will meter WAY better. if you wire the RF to 1ohm and the DD to two ohm with the DD you would get about 1500 more watts. lol

It does 1500 @4

It does 1500 @4

more like 2kw but it does closer to 3200 @ 2 and 4ohm. so when you are running at 1ohm you are getting a real 3000 not 1100 or so a 3k would give with after rise. i meant to say 1ohm.

yeah 1500 @ 4

The efficiency and reliability of those amps are where they get the price tag.

Although for 1400 you can get a solid deal on some big used amps.

Id pay 800 for it but not much more. they are no doubt ****** though,

The T2500 is around 50% efficiency at 1ohm.

Really? thought it would be a bit higher... That 75% they advertise for must be a @ 4ohm

If they were 800 I don't think there would be any reason for anyone not to have one. Sheeet I'd probably have a few at that price.

Honestly, I'm not sure how they sell because you don't see many people with them tbh.

yeah efficiency for regulated power supply amps s*ck but they produce power.

A lot of nuthuggers run them. You can find them used for 500-800 in my area. I'd have that amp over any korean 5 or 8k anyday if I was only running 1 ohm.

However in that price category i can have a brazilian 15k instead lol.

I really love my T2500-BDCP, but I prefer the power flexibility at different impedances since I change up subs every 6-12 months.... Also granted I didn't pay anywhere close to 1400 for mine.
