Replacement subs for Cerwin Vega PS-215B
I have just acquired a pair of these 2x15 sub beasties from a friend of mine for silly money for doing house parties. (They were taking up room in his kitchen...)
Apparently 2 of the 15's are blown and need reconing. Also the cabs need to be sanded down and re-sprayed (pref Trimite). However they look and feel very solid.
The drivers are PS15-16, (16 ohm, 400 w rms) have no thiele small params just this link. http://www.cerwinvega.com/products/professional/ps215b.html
Also not impressed with the 30-45hz O/P from above link.
I am considering two main alternatives:
A) Recone 2 blown drivers @ cost of recone £65 inc vat per driver (Wemb Loudspeakers)
B) Sell the 2 working drivers AND Replace all four units with either FANE, Beyma,RCF,B&C,PD. (Thinking Eminence's would want bigger enclosure). Lowering enclosure impedance from 8 ohms to 4.
Ideas/Suggestions anyone ?

Problem is, most woofers will have the same response in this box, because they will have to live with the tuning frequency that Cerwin Vega already chosen.
If you go with woofers with higher efficiency than 95 dB/W/m, then it will be louder.

After considering the above, messing with various TS parms in WinISD, considering costs and "googling", I have decided to replace all units with one of the following models,
a) Eminence Delta 15 (450 W RMS)LF £54.95 new
Cheaper but not as sensitive as kappa, 2.5" alu voice coil, 14.5 BL , happy in 6 ft cu area it needs to fit (with proper porting), will give enough 35hz with plenty equ & big amp, and will be replaced later with rolls royce driver when revenue returned. For some reason F3 seems better than kappa !?
b) Eminence Kappa 15 LF (600 W RMS) £74.95 new
More expensive than Delta , 101 db sensitivity, Higher power handling, 3" copper voice coil , happy in 6 cu ft, low'ish Qt, respected on the net, probably won't ever upgrade.
Suggestions/Comments/Experiences anyone ?
