Need one 10" sub for SQ

[JimJ]

IB is not the same as free-air. You are seperating the front wave from the back wave, basically a huge sealed box. Very very efficient, it may be hard getting a good seal though.

Thank you, sir A new poster that understands this...I can't count how many times people confuse these two.

The reason people confuse the two terms is because to most people they do mean the same thing. What ray21 is calling free-air is actually just a test to find the sub's free-air resonance (which is different).

Free Air Resonance - the natural resonant frequency of a driver when operating outside an enclosure.

Free-air and IB are generally interchangeable terms. For example if a guy says he's running his sub free-air, you an be assured its 'infinite baffle', not just the sub sitting on the floor playing without a box.

So to confirm...If im getting a Dual voice coil sub i should get dual 2ohm? SVC 4 ohm?...When running one set of comps and one sub being powered with 160watts.


65Wx4CH @ 4 Ohms
80Wx4CH@ 2 Ohms
160Wx2CH@ 4 Ohms

Yes, to bridge the rear channels to a sub you need a sub with either Dual 2ohm voice coils (if it's a DVC), or a single voice coil sub with a 4ohm voice coil.

Seriously consider an Elemental Designs 11kv2. Their new k series has extremely good sq and should be very efficient in a ported box. Just make sure the box you put it in is tuned low (26-30 hz) to maintain sound quality. Here is their website: www.edesignaudio.com
