What ???

That is what I get for posting and talking to my wife at the same time.

I meant they are pretty efficient and low power requirements. So you can run quite a few of them off a modest amp.

Ok, thanks. Still trying to get my head around the IB thing and couldn't fill in the blank myself. Do you think an EP1500 could power 4 of these or would you need an EP2500?

Ok, thanks. Still trying to get my head around the IB thing and couldn't fill in the blank myself. Do you think an EP1500 could power 4 of these or would you need an EP2500?

I modeled 4 IB15s in WinISD. Using an 18hz high pass and they reach max excursion at 20hz with 563 watts using a 16hz high pass they need 430 watts. Pretty sure an ep1500 would be over kill. But it gives you room to grow. You can power all 4 of them from one channel, and if you want to add 4 more later the other channel of the ep1500 can handle them You could probably power all 4 of them from an O-audio or pe 500w plate amp.

Depending on how tight your budget is will determine what amp you want. Don't forget with a pro amp like that you'll need something to act as a high pass filter. The plus side of the AE IB15s is for a pretty good response you don't really seem to need an eq, although I'm sure it would help alot to make up for in room dips. That is the nice thing about the plate amps, they usually have a high pass built in. But the negatvie is alot of them have low end boost that can change the cone excursion down there. You could buy my o-audio 500w bash amp, wanting to upgrade to an ep1500 :bigsmile:

You can also post over in the AE forums, Simon5 and John are pretty helpful. You can give them your specific goals, room layout, budget etc and they can give all sorts of details about how the IB15 will perform and what gear will bring the most out in it for you.

Hey, thanks alot for the detailed info. I'm just starting my build to complete my HT system (Dynamic 2CC and a pair of 1Ss to complement my mains). The IB will come after that but I'd like to try and sort out what my best solution might be for LFE, so all advice is greatly appreciated. I realize a lot more detail will have to be provided about my specifics for anyone to go into detail, but just understanding the general concepts around a good IB setup will help me make a few choices as well as satisfying my curiosity.

I'll continue to lurk and learn and once I have more of my goals and budget nailed down, hopefully, I can ask the right questions.

If you haven't checked out the Cult yet, head over to http://ibsubwoofers.proboards.com/index.cgi.

LOTS of IB information.

 

[ripcard]

Yes, thanks. I've been lurking around there as well.

I can't seem to find a definitive answer about what parameters to look for when choosing a subwoofer for an IB system.

and you will never find it.

humans are not intelligent enough to know an answer to a question like this.

individuals can know the answer but not people on the whole.

same thing with economy - it may be obvious to somebody like me but good luck trying to convince the masses.

i will probably be dead already and people are still going to think that high Q is what makes a good IB woofer.

good luck.

Hmm Vas, you sound a little down on humans...I don't blame you. Bad night though? I mean I think it, I just usually don't say it out loud LOL!

 

[tibuan]

The information i just needed. Been searching for a good woofer for quite sometime. Thanks for the help!
