I bought two of these. Dual VC subs from Fi, called the X (2in VC, as opposed to Q that has the 3in so should be a tamer version with better SQ?)
12 DUAL 4
Fs: 25.7 Hz
Re: 3.9 Ohms/coil
Vas: 104.1 l
Spl: 88.6dB 1W/1m
Bl: 20.0 N/A
Sealed box: .9-1.3 cuft
Ported box: 1.6-2.2 cuft
Sub OD: 12.500
Cut ID: 11.125
Mounting depth: 5.750
I wasn't sure if I want these in the same cabinet or not, and originally these were recommended to me by another member for an SVS clone (their tripple ported dual 12 sub). I may or may not do that later, but for now I want each in their own cab so I can use them under my mains for both aesthetics and speaker stands. Also I would like to run them in stereo once I get a good amp (or two monos).
Here's what I came up with as a best compromise for space v. curve.
Vented: 110L, 19hz, 1x 4in port of 20 inches.
This sub seems more cut out for vented boxes, though I'm still leaning sealed. It does drop a bit quick, but I'm assuming with room gain it'll even out a few dB. The difference in SPL between sealed v. ported doesn't look like a lot, though the group delay is insane for vented! I read as much as I could about it, though nobody has any concrete
info on what Hz v. ms is audible, but I think i'd rather have the quick response of the sealed box down low. I like to believe I can hear that kind of stuff.
Whadya guys think?
Ps. looking for a good amp as well. Doesn't have to be 2ch, but it does have to be inexpensive. E-bay?
