Anyone used or seen third party measurements on one of these yet?

It's very reasonably priced:

And seemingly well built:

It's got serious potential if you need lots of juice.

I think Bossobass on AVS used the 5050 and had a lot of issues with it; I think it caught fire once.

He's used the 4050 (smaller model) and has 0 issues with it at all.

 

[Allanf714]

caught on fire, yikes!

The 4050 is also very well priced. I'll have to look up that thread.

Looks like a Crest Audio design--look at the attenuaters and rack handles....

 

[Allanf714]

That's what I was thinking (also indicated in another thread at AVS). Check out the internal pics here (post #34)

and compare those to the internal pics of the real CA-18 (post #37).

It's a Crest CA-18 knockoff. Not as good as the Crest from looking at the caps and internals, but for the price it should be solid. I wouldn't call this a EP2500 replacement. It's more expensive and should replace 2 of the Behringers.

 

[Allanf714]

I certainly didn't mean to imply that it would replace the EP2500. It costs right about twice as much and has the potential to deliver right about 2x the power. If it delivers on the bench... it has about the same "bang for the buck" ratio as the EP2500.. but a better fit for those power hungry drivers.

I did skim through Bossobass's thread over at AVS. As of a couple of days ago he was still using his MA-5050 and I didn't see anything mentioned about overheating or catching on fire. He did mention that Marothon recommended a 20 amp line for this amp. Seems kindof restrictive.

I'll have to re-read it (not now, I need to get stuff done), but I thought he switched over to the 4050 from the 5050 due to reliability issues.

But from what he did measure, it went flat to something like 4-5hz, which is awesome. Fan modding would be a must though.

The nerve of some people.. getting actual work done btw the hours of 9-5 :innocent:

I skimmed through the thread pretty quickly but I do recall that he was surprized by how "variable" the fans really were. Not sure if he commented on their overall level though.

I was admiring the price of the MA-4050 via the link above. A good number of the amps in that series could be great buys.

I think it was the American Audio 5001 Bosso had trouble with.........his Marathon 5050 has been fine so far (as far as i know).:huh:

Yep. That's correct. It was either the AA V5001 or the V6001. WOTW's killed them.

We don't know about most other people, but for years we've simply avoided American Audio for any serious (reliable) sound system.

Do you think a 4050 can come closer to meeting specs that an ep2500.

I am looking for a true 1000w/channel at 4ohm

To do what tweeter or sub duty? budget in mind? does the amp need to be reliable since gonna your bread and butter? true 1000 watts a side look at QSC MX3000A 1200 watts a side @ 4ohms tested and can do it all day.

woooow thats pricey. I obviously have a budget or I would not be considering the 4050.

the 550-600 it goes for is a budget stretch

I still haven't seen any third party testing on this unit....so it's anybody's guess. Seems to have a pretty solid build and I confirmed with Bossobass that it was working and holding up pretty well for him.

Used about 700-800$ US not too bad for a good quality amplifier that as a proven performance(got mine for 500$ Can. was extremely lucky), this is why i asked you if that gonna be your bread and butter(the show must go on) or just a home theater.

Other amp to consider Crown CE4000 about 500-700 used really good amp, or you can always get two Behringer EP2000 and bridged them will get you about 1000 watts RMS each @ 4ohms, it all depends how you gonna used them for a live gig the Behringer will probably go thermal which is really embarrassing but home use will not be a problem and would be cheap. Even a used QSC RMX4050HD would be in the price range if you are patient and you do not need to roll the dice on reliability record :T

To me the big draw of the marathon line is the selectable input sensitivity. That is huge.

 

[Allanf714]

Good point. Does the EP sport an input sensitivity adjustment?

nope... I've never actually seen that feature before
