Santa is bringing the bass!
Ok, I am in planning and purchasing mode, I've done a lot of reading here and after much learning much about IB subs here - I have the bug. I have made up my mind to do it and shore up the wall to reduce the vibrations. I will be ordering components near the end of November for a build to start Dec and finish at the end of Dec - My company has a mandatory vacation period one week at the end of the year - so the idea is to spend that week finishing up the subs and be ready for a new year of bass.
My current thoughts on setup are the following based on what I have read here:
- minidsp - was looking at 1124, but minidsp is more....geeky??
- Behringer EP4000 - good old standard with plenty of true RMS power
- 4 Fi IB318 18" drivers (I have over 50 * VAS behind the wall - so I am good there)
- one or 2 manifolds - have not decided - more on that later
This appears to be what many people have gone with in the threads.
My main goal is to have something that is great for both music and HT. I have a Magnepan setup right now and they are not the best HT speakers and blending the Magnepan 3.6 and subwoofers is near impossible. But I have read that IB subs are different in that way. I really hate one note bass and bass heard that is the result of cabinet resonances and do know what a sub is supposed to sound like. My biggest fear with and IB sub is that it is going to shake the front wall badly(just from the air pressure) - and that will affect the sound. The front wall is a staggered stud wall and as such is more prone to vibrations. I will have to do some sort of stabilization of the front wall.
One thing I would like some advice on before I order the drivers(and begin the few weeks wait) is should I get the 2ohm or the 4ohm version of the FI IB318 drivers?: http://store.ficaraudio.com/ib318
Per the driver wiring diagrams on this site I believe I could get 4ohm or 8ohm bridged configuration with either the 2ohm or the 4ohm drivers. It that is true - which is better - is there a difference? I guess there is less windings on the 2ohm version?
Thanks
