AMP Recommendation

Looking for amp suggestions.

Based on several reviews from this site I have decided to use (2)RSS315HF-4 12". Each will be in it's own separate sealed box aprox 2.5ft^3 tuned at about 20-25hz. This will be used for HT and Music.

My question is regarding the AMP: I've been intreged by the reviews of the Behringer 1500/2500 but don't know if they will work well with these sealed speakers. I know there are several plate amps that allow for low level boost etc. Also, the Behringers seem to either have a 30hz or 50hz xover which seems a littler higher than standard plate amps....????

Not sure if any of that matters in the real world.

Re: AMP Recommendation

Hi and welcome the forums

I use a Behringer EP4000 with my sealed sub and it works very well. These amps have selectable 30 and 50hz filters that can be turned off so no need to worry about those being an issue.

I agree, The EP 2500 or the 4000 are the best bang for your buck. I use them and so do many others with great performance.

Re: AMP Recommendation

I'll take a look at the 2000. I was initially interested in the 1500 because it seemed adequate for the money $199. Bridged mono output at 8ohms was more than the my speaker's 400w rating.

I have a feeling the published specs don't quite tell the whole story with the 1500?

Re: AMP Recommendation

EP2000 is just an updated version of the EP1500. There may be a little more power in there, but I haven't seen any test reports on either it or the EP4000 (updated EP2500) yet to know for sure whether Behringer managed to increase power over the older models.

Personally, if I was looking at the Behringers and wanted more power than the EP1500, I would forget about the EP2000 and go for the 4000.

Re: AMP Recommendation

I doubt I would need more power than the 1500 has to offer.

Just came across an actual test of the 1500:
400w at 4 ohm/2 channel .023 THD
800w at 8 ohm mono .016 THD...probably overkill

Re: AMP Recommendation

Dont worry about a little overkill, in fact its a good thing. If your amp has power its not using then your getting a nice bit of headroom. This means your staying out of the amps distortion range and supplying nice clean power to your sub/drivers. The only thing to be mindful of is putting to much clean power into the sub and blowing it. You can employ filters to help protect your sub, but care is still needed if you amp is very powerful.

Have a look at pricing, from time to time deals are floating about. I know a friend of mine who got the EP4000 because at his time of purchase, it was on offer and only about £2 more than the 2500, so couldnt really be refused.

Which ever model you choose, I'm confident they can all supply enough power to get good results from you driver.

Re: AMP Recommendation

Question about the EP 1500/2500.

Read a number of post regarding noisy fans etc. Are the fan on these amps variable speed or do they run constantly? Also, do these pro amps fans run even when just left on???
