Room is 14x35x8 with the HT part kept within 20 feet of the 35 and open to the rest of the basement. Subs are":
4 x IXL 18's in a IB
2 x mal-x 18's
2 x mal-x 21's
2 x FTW 21's

The ib is running off 2 ep4000's, the mal-x 18's have a bridged ep per driver and the 21's have each a channel off the 2 clones. Ep clip light were dancing with both the 21's. the Clones are ummm awesome? lol. I can eq to 15hz with no ill effects with the clones (probably lower but meh), heck they are barely running LOL.

A bridged ep will get you some serious output with the FTW's and only really clips on the heaviest scenes.

Goodtimes. Great times!

N8DOGG, (I'd love to see/hear your setup!!!)

Would 2 of these be overkill in a 17x15 size room?
I have 4x MFW-15 (1 in each corner) now and have a lot of bass but I need more!

I'm thinking the 4x MFW-15 up front and 2x FTW21 in the back.
Is that too much?

Thanks for your advice.

Too much? No such thing.

Guys,

Thanks for the confirmation that's it's NEVER too much!

Now the question is would connecting the 2x FTW21 to a single EP4000 be a waste?
That's all I could do cause the other EP4000 would power the 4x MFW-15's.

Does that make sense?

Thanks

You would be fine.....we all here just like mass overkill and20db's of headroom.

Sorry to ask but what size of cab (sealed) would I need per sub?

You would probably want a clone as an ep isn't going to fully work them out. As bosso is always pushing make sure you have proper amp head room so you aren't clipping.

I'm going to be using 2 ep4000s in bridged mode to power my two sealed enclosures. My room is 18x14. Hopefully, they'll be done by the end of April and I'll let you know how they do.

I agree with the headroom comment, but with so much power on board with the clone, aren't you in danger of driving the sub too hard that may result in damage to the driver?

You will damage it with clipping too.

I bet you would have a hell of a time melting a coil. But if you are worried about over excursion just make sure you plot you signal shaping properly or just know at what voltage thing go bad and never go above that (xmax leaving lots of xmech).

Just setup your system so that they won't get damaged I was messing around with my ep's today and to be honest, even though the clip light dances, they still had enough power to pay well above reference. I only got the clones because I wanted to get rid of my giant stack of amps and simplify my setup a bit.

Anywhere from 6 cubic feet (mine are about 6.2 after driver and bracing) to about 10 cubic feet. IMO the sweet spot is 7 CF. 7 would be as big as I would personally go but I'm also in limited space but don't feel the gains are worth the extra size.

N8DOGG,

Thanks so much for the cab size recommendation.
that's exactly what I wanted to know.

Now would you know if it would be possible to get these subs at 2 ohms or 8 ohms?

Because I'll be driving both connected to one EP4000 ,I'd like to make sure it's 4 ohms total to get the full 2000watts.

Thanks

Steve,

I checked that out and would love to buy one, but it's going to have to wait.
Budget is not allowing me to do so...maybe later on though.

Thanks for your input

I don't know, mine are single 4 ohm but thats what I wanted. You'd have to email Mark and ask him.

Which placement would be better for the horns, A or B?

Probably B due to better integration of like drivers. May raise efficiency closer to the theoretical maximum. And considering the spacing difference I doubt you would notice a very large change in response at bass frequencies.

I was told mine would be the first to ship and that was two weeks ago when he said that. He said he thought the crates would be ready by mid last week but havent heard anything. I'll shoot him an email too.

I just looked back at the last email and it was on the 2nd so almost 3 weeks ago he said they were being packed up and waiting on the crates. I just emailed him again.

Can someone link me to a winisd file that I can just open and model or do I need to manually enter the values. Think I will build the boxes this weekend. My plan is to build 2 boxes that house 3 drivers each and then two identical single boxes.

From the numbers I just plugged into winisd it looks like with 8 drivers and 2 14000 clones ran at 8ohm stereo I can build the boxes at 8 cuft to stay under xmax at 2.5hz.

I would have thought I would need 4 clones but using only two at 8ohm stereo will get me to xmax with 8cuft enclosures. Oh, that would be 9400 total watts or 1175 each from the clone specs.

Should I be modeling these drivers matched with the clones different or do you all think they will put out what they quote at 8ohms?

Its just weird thinking that running two amps at 8ohms stereo for 8 21 inch subs will be anywhere near pushing them to xmax.

Any thoughts guys?
