Re: A cheaper alternative to the Behringer Amps?

It all depends on how the manufacturer "calculates" their "watts". Do they use the peak to peak of an AC waveform (the WRONG way) or the RMS (70.7%) of 1/2 of the waveform (the correct way). And that is just figuring from a voltage.

But How well does the amp "produce " that voltage- continiously-or on a short peak.

There are all sorts of ways to stretch specs. If it looks to good to be true. It probably is.

The only specs that might could be believed on that amp put it in the range of 70-110 watts.

MUCH less than the Behringer.

ANd BTW Behringer amps are pretty much the cheapest amps out there. Real amps cost a lot more.

Re: A cheaper alternative to the Behringer Amps?

Hey there Ivan...You sure are getting around.


Long story short. No commercially available, affordable plate amp gives the power output of Behringers EP2500/4000. It's been tested at about 830w per channel at 20hz into a little over 2 ohms. Yes it threw the breaker with 4ohm bridged testing at 20 cycles, but real world use is not sustained 20hz sine waves. If it was, I would not consider the increasingly popular burst type amps at all, as they fall flat on their face with that type of continuous full power testing from what I've seen so far. A # of other amps from other manufacturer's including Face and Dayton died on the same test bench, so it's not like the Behringer was the only one to have issues. Some of the budget Crown's didn't fare any better either and some were much worse even (XTI series). The Behringers are not the best amps in the world. Crown, Crest, QSC and a whole slew of other mfg's make much better ones, but they also cost considerably more. The Behringers offer what a lot of DIYers want which is just cheap bulk power.

If that much power is not needed get the Oaudio by all means. It tested well for a plate amp.

Skip that Pyle. It'll be lucky to do 100w like mentioned.

Thanks for all the input. All things considered, I have pretty much decided to go for the OAudio 500w. I think it will have plenty enough power for me in my room, and also has the benefit of being able to be integrated easily into the sub design.

Most would consider the Behringer to be low end, but I think by most standards they are a reasonable value. There is no reason to make comments like this that might be considered demeaning to those that use the product, or that might be considered condescending to others.

I think that the take-home point to this thread is that while the Behringer is certainly not a high end product, it is very powerful for the price, and for subs is probably a good choice for many. The reason so many use it is because there is not much of a cheaper alternative for similar power. So to answer the OP question, I don't know of a cheaper alternative with similar or better performance, unless you happen to find a good cheap used amp. The cheaper alternatives will likely have much less power and higher distortion.




Looking for me, just google my username. I have used the same one for most sites for many years.

Although you'll lose 3db of max spl (and therefore some eq ability to a degree), the flip side of that is your driver will only be using half its rated power handling ability, and in truth its probably capable handling slightly over 1000 watts. The driver will remain so far within xmax it will never ever be an issue, which is a big plus with a DIY sub that has no inbuilt protection circuitry. The voice coil will also enjoy the same headroom, so you know its well covered.

The Behringer amp is a real amp. It's not a fake amp for sure. If I hook it up to my sound system it will provide plenty of power for my needs.

Pro-Audio and Home Audio are entirely different scenarios and for home audio the Behringer does just fine.

FYI a person could build amps for much cheaper than the cost of the Behringer even.

Ive never even considered that option. Where might I start looking into that?

You will need a basic understanding of electronics, but once you have it national makes chipamps that cost 5 bucks each and have a spec for building an amp. I plan to build 6 of them for my speakers someday.

Re: A cheaper alternative to the Behringer Amps?

Its interesting information I'll look into sometime. I would have though a simple mono slave power amp module for a diy sub would be a good place to start?
