Hi guys, first thread here. About a month ago I scored a pair of cheap and rough Cerwin Vega 316R cabinets. Missing the woofers and one of 6.5 midranges has had the cone poorly and irreparably repaired of two punctures. I kinda toyed with the idea an Econowave conversion for a bit, but the construction actually lends itself a certain amount of difficulty in clearing real estate for the waveguide and the compression tweeter. My thoughts now shifted toward a nuts and bolts restore with original drivers, but those parts are simply not out there to be had, not even a recone kit for the mid from Simply Speakers.
After Sean from SS informed me of the lack of availability for the midrange recone kit, I queried about substituting a Skar Audio FSX65-8 6.5" replacement, as the original driver lived in it's own sealed enclosure (and therefore substitution less critical), while the rest of the cabinet is ported. His answer was an enthusiastic thumbs up, so choice for the midranges is settled....
The original HS-5 tweeters are accounted for
The 8 ohm 15" woofer is another matter, since it lives in a ported cabinet. The original model is 154W, part number unknown. I am told it has the cast aluminum frame, but know little else.
I am soliciting recommendations from the group, and have been looking at the Goldwood Sound GW-15PC-8 as a replacement.
Inside cabinet measurements are (not including port chamber)
18.25W x 26.75H x 16.25D for 4.59 cu ft.
Port opens to the floor of the inside chamber, is rearward facing at the bottom and measures 18.25W x 3.00H x 17.00D. The crossover points are 500 and 3500Hz respectively.
Any help is appreciated

Here is the product page for the Goldwood Sound GW-15PC-8, with downloadable pdf files for specs and a transducer evaluation graph 2 Goldwood Sound GW-15PC-8 Heavy Duty 8ohm 15" Woofers 550 Watts each Replacement Speakers - Goldwood.com
According to Parts Express reviews the Goldwood 15 you are looking at is a reasonably popular replacement for other Cerwin Vega products w/ 15s.
I don't have experience w/ this woofer, but it looks like it simulates well enough in roughly the volume you have specified given the port size & length.

I was afraid I might get crucified over there for wanting to substitute drivers. These are fairly rare units and cost somewhere north of $1500 when new in the early 80s. But trashed is trashed and missing is missing I guess, and for a 30 dollar set of cabs, I am willing to mongrelize these if I can get good results
My plan is to rebuild the stock crossovers and clean the attenuators then do some measurements. Any suggestions for measurement software and hardware on a budget? Also suggested caps for the crossovers would be appreciated
To clarify my last post, I am just soliciting advice on brands of caps and cap types. I thought that I had read somewhere that a Russian PIO cap across the woofer was the hot ticket to getting sweeter, more musical sound from these boxes. That's the goalpost for this project, something that will play with pleasant authority.
