Just don't forget to build an appropriately sized subwoofer for it

actually i plan on building 2 using this driver

http://www.parts-express.com/pe/pshowdetl.cfm?&Partnumber=295-472&scqty=2

each in a ~4cuft box

http://www.data-bass.com/data?page=system&id=89

was planning on building 1 dual opposed in ~7cuft box like Andrew did here http://www.avsforum.com/t/1435795/f...-looking-to-upgrade-multiple-sealed-18s/0_100, but 2 single will work out better in my space

ive heard his dual caps and cant wait to hear the dual daytons, i actually think he is gonna build 2 more

Great price on a great amp. I have owned one for about 3 years now and it runs two 18" ported subs (8 ohms each) in my small PA system. It barely gets warm after hours of running. Behringer is not known for making dependable electronics like mixers or signal processors, but their power amps are very solid, particularly the EP line. They are ripoff copies of the older QSC RMX series amps. They weigh a ton and are essentially bulletproof. For subwoofer duty you won't find a better amp for 3x the price.

These 'specs' are quite curious.
There is no spec for power into 8 ohms.
There is no frequency response.
No damping factor.
No total harmonic distortion or intermodulation distortion.
No signal to noise ratio.

I don't trust an amplifier with so few specs.

Some specs are available at http://www.behringer.com/assets/EP2000_P0A38_M_EN.pdf
but they are still less than I would like. No dampening factor, or IM distortion, for example.
They just list 'distortion', without specifing frequenct, THD, THD+N, power, or any other important details...

It's amazing what 10 seconds of google searching can find you.

Showing back in stock. $50 cheaper than one we bought through a reseller on newegg last spring. Definitely a deal for a PA quality amp.

 

[Plugers]

Amazon has it again too at this price.

 

[Anubis]

amazon is showing 315 for me

By default yes, you need to select Amazon as the vender.

They are out of stock but will ship shortly.

 

[Anubis]

still not seeing it in cart from amazon is showing $343.36

 

[Plugers]

Wow. It must have just dropped for an hour or so. Back $343 from Amazon.

4000 watts...LOL:

1% THD....sigh.
Also power consumption = 2600 watts

Anyone that's looked into these amps knows this. They have been tested for an honest 1800-1900 watts RMS and at $275 it is a steal, plus they have proven to be super reliable / durable over the last ten years (EP2500 rebadge).

For $300 you could also get a Crown XLS1000, about 1100 watts plus 3-year no fault warranty and very light weight so they can be moved around easy. http://www.parts-express.com/pe/showdetl.cfm?Partnumber=245-500#

-----------------------

No thread-crapping here, just two points of clarification.

First:

If the amp is generating 1% distortion at full power, it's nearly functionally impossible for you to hear it. 1% total THD is about the lower limit of what human hearing can discern as far as distortion (those with "golden ears" excepted). Further, at full power, assuming a speaker with let's just say 89db/1w/1m efficiency, at 512 wpc (conservative output of one channel of the amp), that speaker will be outputting about 116db, or damn near the 120db threshold of pain. If two channels are running it would be 119db through two speakers. 1% distortion output would be well below audible and also, the distortion of the speaker itself (especially a woofer or sub-woofer) will be WAY above 1% at those levels.

Second:

The specs for this amp are all out of kilter. Tell me how it is possible for an amp that draws 2600 watts from the line (120 VAC) to output 4000 watts?? That's a perpetual energy machine. If it does, I'm going to buy a 100 of them and hook them in a loop (output>input) so that at the end, I should have a power-plant in my house with the extra energy that they create above the input.

Also, this amp claims to draw 2600 watts from 120VAC. Impossible on a 15 amp circuit.

P=I*E, so assuming a 15 amp circuit in your house or wherever, the MOST you can draw from a 15 amp circuit is 120V*15A = 1800 watts. On a 20 amp AC circuit it would be 2400 watts.

Another point to note: Amplifiers do not run at 100% efficiency. A class-A amp runs at 25-30%, a class "D" amp around 80%. Presuming it's a class D amp, 1800 watts INTO the amp would only equate to 1440 watts output for BOTH channels (15 amp 120V AC circuit).
--------
Even at rated 575 watts RMS into 8 ohms, it's still a LOT of power for a great price. For those who don't know, you have to DOUBLE the power of an amp to get a 3db increase in the volume of the sound (3dB is generally regarded as something sounding "just a little bit louder"). To get something to sound "twice as loud" requires a 10dB increase in volume, which requires a ten-fold increase in the power of an amp.

So at 575 watts at 8 ohms RMS, you'd have to get to nearly 1200 watts to get it to sound a "little bit" louder and to almost 6kW output to sound twice as loud. (Let me know how your hearing fares on that one, kiddies).

Much love and respect,

Throwing another couple deals in from my Parts Express email -

BASH 300w amp for $112: http://www.parts-express.com/pe/showdetl.cfm?partnumber=300-750

BASH 500w amp for $179: http://www.parts-express.com/pe/showdetl.cfm?partnumber=300-752

I have the 300w on my Sonosub, it's a beast! :awe:

 

[Uhtrinity]

The amps built in circuit breaker is 20 amps, so that 2400 watt draw rating sounds right. I always took the 4000 watt rating as peak. 2000+ watts rms sounds correct. I've never been able to run my amp above 50% as it is "too damn loud", my kw meter showed just over a 1kw draw

I've considered buying a second one to use for our monitor amp, but it looks like it is oos again.

 

[Plugers]

In the test I read they had it connected to 20 circuit. It also said that it pulled 84amps in very short bursts, according to the article too short to trip a breaker. So not playing sine waves under that kind of draw.

That Crown looks good too with the built in crossover. I'd say Crown is a better and more innovative company, but the Europower product line itself is as good a product as a Crown PA amp.

 

[Mongoloid]

Any amp that does not double power with halving of load from 8ohms to 2ohms is weak sauce.

 

[fschris]

Don't over think this here. The price is good. however I use the iNUKE DSP 3000 for my subs. These are good for sub duty. They only need to output large doses of energy in short amounts of time. its not like an Explosion in a movie last 20 minutes straight!

These are good for Home subwoofer DIY on a budget.

They run about $100 more iirc. I may go that direction in the future, but the EP is bulletproof. I couldn't find a whole lot of reviews on the iNukes.

Some people just gotta keep finding the smallest thing wrong with a great product. Let me try this again:

Years ago, Behringer ripped off the design of one of the most reliable power amp lines in history, the QSC RMX. The "EP" series is what they came up with. IIRC, QSC sued and LOST. Something about a technicality of something on the circuit board. (I'm not Googling for the exact thing...you can do that if you're bored). The EP4000 is OLD SCHOOL TECH. You could probably throw it off a roof and it would still work. It weighs more than a boat anchor. It is not a quiet amp (fan). It works well. Period. If you NEED onboard fancy DSP, this is not the amp for you. The EP series gained it's popularity as a subwoofer amp for HT, but they do just as well as a sub amp for a PA system or for mains for that matter. These things have been beat to hell and back and they still work. The EP series amps are the ONE Behringer product that pretty much nobody has anything negative to say about. Sure; there's always the 16 year old "DJ" that connected 42 subs in parallel, outside in the rain, in August and then complains that the amp blew up.

Me personally, I've never run a 2-ohm mono load but some have with no ill results, save the amp got hot. I've run it at 4-ohm stereo and 4-ohm mono, LOUD and all day long with no problem. If you don't want one, don't buy one. If you're thinking about it, just do it. Buy a NEW one, not a used one unless you can verify it's history. It is the best buy in this price range, bar none, particularly for sub duty.

FWIW, my little PA system has an EP4000 for subs (two, 8-ohm 18-inch ported subs, one per channel), a QSC GX5 for mains (two, 2-way, 12 inch tops) an a Behringer A500 for monitors (cheeeeepo no-name 10-inch wedges) when needed. The A500 is underpowered for mains, but it's what I have. I can do PA duty for roughly 150 people with this setup. No complaints so far.

Good to get your input. Glad that it's reliable design.

Just wish amp companies would be honest with their specs. They should be both channels driven and 20hz to 20,000hz and RMS power, not peak or max.

I'd be curious about the warranty on this amp and how well the company stands behind them.
