Replacement subs for Cerwin Vega PS-215B

Archived from groups: rec.audio.pro (More info?)

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 units are PS15-16, (16 ohm, 400 w rms) have no thiele small params

specifications

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 ?

The enclosure is two sealed units, so approx 170 cu ft per driver, with
two ports approx 5" dia per driver. Don't think there is any port tube,
so port length is approx 3/4". Will probably have to lengthen each port
to get f3 about 37hz. (Havent collected boxexs yet, going by memory)...

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, 24 BL ? Respected
on the net, probably won't ever upgrade.

Suggestions/Comments/Experiences anyone ?
