I just got an EP2500 that I'm going to use to power my center until I can get the funds for IB drivers but had a question about racking it. I currently have a pair of front rails that go floor to ceiling. Up top I have some power conditioners, my BFD, and a DI800. Down low I have a Crown XLS 402D powering my mains. It looks like the air flow of the EP2500 is opposite that of the crown so I'm concerned about how close to space them. Also, right now I only have front rails, is that enough support for the ep2500?
Thanks!

Yes the air flow is opposite. I think you'd need to be pounding these things pretty hard before you'd have a problem with the 2 amps.
Were it me I'd use some kind of support for the rear of the amp.
Rails themselves are pretty inexpensive. Can you install a set of rear rails?

Yeah I think I could add some rear ones. I just have them screwed to some 2x4s. The guys at the local pro shop assured me that the crown didn't need them so I opted for just fronts.
Thanks!

Hi brussell, I would have to say I agree with Thomas W here. I made my own mobile rack (images are on my build thread), using 2"X4" for the uprights, and secured my EP 2500 front and rear. These amps are very heavy, and I did not feel comfortable with only front support. Now, fan noise, that is another issue to be resolved shortly  Cheers, Jim. |

I have 7 amps that are front mounted. I think this is standard practice for most pro equipment even though the manual will tell you otherwise. The only problem I've had is a couple of threaded rail holes have stripped from over tightening. A nut on the back solved this problem though.

Thanks for all the input. The amp arrives tomorrow and I guess I'll see just how loud it is and if it causes a problem. I do have it mounted in another room so I'm keeping my fingers crossed!
Thanks!
Brad

Jeez goofus, Who in their right mind, really needs 7 amps? ( besides Thomas). You are making me feel really inadequate here ;D I know, I know, you got them cheap, but sheesh, spare a thought for the less fortunate here  I am just insanely jealous, but I will get over it  I am sure your setup, when complete, will bring the house down, hopefully not literally  Cheers Jim. |

I'm like that old lady with all the cats. I don't need them, but they comfort me. Plus my amps don't stink up the house as much.
On a related note, a funny thing happened last night. I was making a change to my rack and stripped out another hole. The amp had two screw holding it on top and one stripped on on the bottom. I thought the stripped one would hold for a second while I picked up the last screw to install it, but no luck. I sat there with my hands under it for a bit and it was fine, but as soon as I turned around the back of the amp dropped pushing the screw out. The top screws saved it, but they were bent to hell.
Rear rails definitely make these heavier components easier to install safely.

I know this thread is quite old now, but for future reference I wanted to add that rack shelves are quite cheap and I have used them upside-down with excellent results to support Dell servers without rear rails. Our Dell servers are heavier and much deeper than my Behringer EP2500. As an added benefit the shelves make it easier to place equipment while trying to screw it in. The only downside is that an upside-down shelf takes a couple rack units below the equipment.
