Ok here is a question. What pro amp would be a good sub amp that is in the price range of 2 or 3 hundred bucks that you don't have to do a fan mod to and has enough power to run a medium sized sub. Or does that not exist?

Get a used Adcom GFA-555 II off of eBay. It will be in the $300 range, and has no fans. It will output around 350 x 2 at 4 Ohms.

But I would suggest the EP2500 and fan mod. It's VERY easy. On the same level as changing a PC fan. In fact, it's the same type of fan, with the same type of plug! It's just a 24V instead of 12V. The EP2500 will be the best sub amp for your price range. No question.

I was just given a Yamaha P5000S for a dirt cheap price, barely used. I actually just tested it out yesterday with my Yamaha S112 IV pro speakers (which the amp is optimized for with the YS processing). Running the speakers in my living room, the fans never even kicked on at nearly unbearable levels. I don't plan on using the amp for home audio but I can say it would definitely work. I detected no noise with no signal present and it has more than enough power for just about ANY home application. :) I especially like the built in crossover for use as a sub amp. I'm surprised these Yamaha amps aren't discussed more.

I would like some opinions on this. http://www.directproaudio.com/images/products/cpxspec.pdf I was thinking of the 900 model for my sub.

Mike I hope you don't mind me asking in this thread......
I have a Crest CC1800 I use sometimes as a monitor amp powering some JBL 15" booth monitors and other times use to power home speakers. My amps kind of rotate though...

Buying the American amps is a good buy right now because of the exchange rate for the foreign stuff. Crest makes good stuff and has been around for a while. Variable speed fan, not too noisey so maybe for a home it wouldn't be bad. The CPX I'm pretty sure is single speed.

Never used it to power bass bins or anything, but, I'm sure it would work well especially in a home.

Thanks, I decided to go with the 2500. I got it for $298 with free shipping from djdeals so not bad. I will order a fan for the mod and I will be all set.

Be sure to get the Panaflo model that is known to be the lowest noise fan known for this application. I don't remember the model number at the moment, but if you don't know which fan I mean, I'll get the number for you.

EP2500? It should serve you well. The Behringer amps are a good value, just avoid their mixers and such (I know that isn't your thing anyways). The service is bad too, but you'll void the warranty by modding the fan anyways. They don't seem to travel well, I've seen a lot fail but I don't think it was due to bad componentry. The Yahamas travel a lot better and I haven't seen any fail, but they don't have the watt/$ of the Behringer.

I own a Behringer Xenyx 802 and it was purchased because not only does it measure as a completely neutral device (unless coloration is being specifically applied) it also is of high build quality. It also seems that the other mixers in this line are of the same build quality. I see no reason to avoid these specific mixers if one needs a high quality, low cost, unit.

It seems highly unlikely that there is a large proportion of EP2500 units that fail unless defective. They have redundant double-soldered joints on double PC boards and use relatively high quality parts as well. While it might be possible for the occasional failure due to extreme abuse on the road, it seems fairly unlikely for them to travel poorly due to their superb build quality. Do you know what the cause of breakage was?

I will use it for my HT so it won't do any traveling. I do have a question, I run a few Rolls mb15's to balance my signals from my Pioneer Elite to the amps but should I do the same with the 2500? I heard that the art cleanbox was messing with low frq's so without a mod it isn't good to use for subs. I am going to call rolls to find out if that model does the same. I don't need,at this time, all the wattage the 2500 will output so does it matter anyway?

For what it's worth I just got of the phone with Alex from Rolls and after asking me to hold so he could check and be sure he assured me that the mb15 does not effect freq's at all and is good to go for sub use. :)

I'm talking about their DJ mixers. Soft faders, poor sound quality, crosstalk. They also have a bunch of stupid features, but that is a personal problem not a technical one. But, I shouldn't be too hard on them because they are cheap.

Mixed bag. Two times I've seen them perform very well and then just quit in the middle of the night. Might be due to being rocked around a bit too much travelling, but I have no idea. For what they cost though I know people that buy them and say "well it'll probably fail eventually but I can buy like three for the price of an equilivent QSC or Lab." A lot of clubs provide the amplification, basically all do, so putting much money in your own gear gets kinda silly unless you do a lot of house parties. They are 2-ohm stable for cheap. I opened a failed one up once and the board was cooked, probably just overheated itself. I'm not sure exactly what the problem was though. My diagnosis was "it smells funny." :D

This is a completely different application though. If you crank the amps up as much as these failures were at, your going to have the cops at your door.

I'm not sure. I'd call Rolls. What do you mean messing with the low frequencies? I have a Whirlwind LM series converter to take my laptop up to +4, and I haven't noticed a problem with the bass. I can't say I've tested it though. I wouldn't expect their to be a problem with the Rolls, I'd call them to double check. They'll probably just tell you it's 20Hz to 20kHz though... apparently that's what every piece of electronic is. ;)

Over at another forum they have a mod for the Art cleanbox to fix the low frequency problem. I guess it cuts out starting at 30hz if I remember correctly. The Rolls does not.

P5000s for me. Sounds overkill... but you'll never "have" to buy another amp again. PLUS you can always bring the Bear's out of retirement and use the 5000 as a sub amp...

I've always tried to get the best I could afford; because I won't typically have to re-buy equipment when/if I upgrade other components and I can enjoy listening more instead of barking about "do I have XXX?"

Now I need a belt for my 8-track player. :D

Rolls is basically the same unit

I'd get the Whirlwind if you are worried about the deep response.

A lot of pro-audio gear isn't as concerned about shooting for 20Hz, as most material isn't much below 40Hz. A lot of pro bass bins, be it scoops, horns, bandpass, are looking for their output 35Hz or whatever at higher outputs. Deep bass down to 20Hz and lower is achieved by "stacking" for the output but it generally uses higher dollar stuff than those entry level Rolls or Arts, or doesn't need a converter at all because its all balanced. For 100 bucks and some change you can get the Whirlwind. Not that Whirlwind is magical or anything, but, I'm pretty sure the output is okay down to 20Hz... at least the manual says it is and I haven't noticed any problems using it and I go down that low.

Peace
