Sweet!

I already have 2 Mal-X 18's but Kevin keeps on coming out with even crazier designs that make me want to spend more money:help:

Would a EP2500 be enough for the 21"? I tried running a single 18" off of a PLX2502 which wasn't enough but my PLX3402 matches up great......too bad I don't have another 3402 for the second 18":crying: My room is on the large size though and open to other rooms besides the fact that I am a sub nut.

According to the owners manual, the EP2500 will run 750watts @ 4Ohms per channel. I think Kevin mentioned to me that is plenty by itself, let alone 2500watts bridged. So even if the numbers are fudged a plenty on the amp, it should have enough juice to drive the 21".

Once I get mine built, I'm going to try the 21" on one channel, and my current dual 10" folded horn on the other channel. But I'll probably just bridge the EP and run the 21" alone.

The EP2500 (or the EP4000 that has replaced it) is a great bang for the buck amp...otherwise it wouldn't be so widely used by so many DIY builders.

Maybe in theory that is correct but in practice I need more power. If you have a small to medium sized room that is closed off then less power can be had but if you are trying to energize a large open room the the more power the better.

I was not bashing the EP2500, just mentioning I had the PLX2502 as they have comparable numbers. I think the EP2500 is a fine amp that I listened to at a friends house who I built a sub for. I plan on picking up either a EP2500 or 4000 to see about saving some $$$$ by selling my PLX2502's.

The M-18 ran good with the PLX2502 but I could hear spots were the amp struggled, with the PLX3402 those struggles are gone and the M-18 loves it. I would have to think the M-21 is going to like plenty of juice as well. Somehow I don't think a single channel of a EP2500 will be enough in a sealed alignment for the M-21 especially if any boost is added down low.
