Fi q18 infinite baffle

Well thanks to the great deal I managed to get from Sonnie I am getting ready to do 2 manifolds each with 2 18's. They will be installed in a full open basement, I am planning on using a inuke 6000dsp to power them, will this be ok power wise? And what sort of feedback can I get from fellow members about using these in a infinite baffle setup?
I have researched quite a bit and reading over at the cult and many comments and post claim these are better than the ib subs they sell? Any help is appreciated.

Well I was hoping for some kind of feedback. Maybe everyone is busy due to the holiday season.

I don't have Winisd on hand but modeling them sealed in an extremly large enclosure should tell you how much power they need before getting in danger zone. From experience I would say that the Inuke 6000 is probably overkill.

Re: Fi q18 infinite baffle

I'm running 2x18" FI IB3 manifold using the inuke 6000, have been for over a year now, personally I would go with one of these for the money. I compared it to a behringer 4000 I had and they seemed to yield similar output, however the Behringer was bridged, so the inuke offered me 2 channels which I was after, I use the spare channel to run a Quake 10B. I also have a 4x15" FI IB3 in manifold, I run these of a QSC RMX 2450 'bridged'.

I'm sure you've read this but I will stress, positioning of the IB's is key to success. Don't be afraid to run them front and back of your room if this helps with the bass response. This is what I do to great effect, there was no other way of removing the null I was sat in.

Re: Fi q18 infinite baffle

The wife was kind enough to surprise me with a inuke 300dsp. So now I am wondering how I could wire 4 2 ohm subs to get the most power out of this amp. Is it possibble to wire 2 sets of 2 in parallel which equals a 1 ohm load the wire those in series at the amp bridged for a 4 ohm bridged?

Well they are officially built and installed. Just waiting on my cables so we can fire them up. I can't wait. But the wife sure can. Lol

Looking good. Once up and running, are you able to check the bass response from the main listening position using REW?

Sweet. From what everyone says IB is the way to go if you can make it work. I am waiting for a friend or a neighbor to do one so I can listen to one

Orion...if your by chance near Ohio feel free to contact me to check it out.
First impressions are lasting impressions for sure. This has by far exceeded my hopes or expectations. Without any eq or running any room correction it is absolutely effortless. But capable of knocking your on your rear at any given surprising moment.
