Rawson Sparfield sells a 100w Fane Crescendo 12A replica that is a very accurate recreation of the original, using a similar cast metal frame, the same magnet and voice coil specifications, and aluminum dust cap just like the original. It is named the Starfinder, after the name of the WEM Starfinder speaker cabinets that Gilmour is so much associated with, and the company is named after Rawson Sparfield Ltd, the original builder of those Starfinder cabs, although RS is not affiliated with either original company. RS is run by Jeff Lewis, head of the U.K. amplifiers and speaker cabinet company Matamp, and Chris Hewitt, owner of Ozit Morpheus Records and CH Vintage Audio. Chris is a music gear collector with a large collection of vintage WEM audio equipment, including one of Pink Floyd's early mixing boards bult by WEM.
The Starfinder is made in the U.K. using Kurt Mueller cones and the magnets are charged on a magnetizer used by the original Fane speaker company. Visually the speaker looks very similar to the original Fane Crescendo, but the spoke holes in the cast metal frame are not as wide, the underside of the magnet has a beleveled edge rather than a corner like the original, and the hammerite finish pattern is smaller and smoother looking. RS sells the speakers individually, and also loaded in their Starfinder 4x12 speaker cabinet, which is a replica of the WEM Super Starfinder 200 4x12 cabinets that David Gilmour used. Hearing a Hiwatt through the Starfinder speaker is instantly recognizable as the Gilmour Pink Floyd sound, especially his early to mid 1970s tones. All Crescendos do not sound identical, but compared to my originals, the Starfinder is slightly darker with less upper mid range. It is still very close

"Today I have moved several degrees closer to my sonic ideals, thanks to my new Rawson Sparfield Starfinder 12" speaker. Chris Hewitt and Jeff Lewis of Rawson Sparfield have meticulously engineered this speaker to come as closely to the legendary Fane Crescendo as possible. My disclaimer is that I've never played through an actual Crescendo, nor do I have anything like a WEM cab to install this speaker in. But that's not my goal. Those of you who know me as the tube guy will recognize that I'm very much obsessed with audio clarity, and that search is what drew me to this new re-creation of the Crescendo.
The Starfinder is rated at 100W. I chose the 8-ohm version. Specs are on the site, but they don't list the efficiency.
I'm guessing about 100dB, based on relative volume impressions when comparing to other speakers. https://www.rawsonsparfieldloudspeakers.com/speakers
Many thanks to @Kit Rae for bringing this speaker to my attention (check this out)!
Shipping was extremely fast; two days from Britain to San Francisco Bay Area. I don't even know how that was possible.
I was pleasantly surprised to have this speaker waiting for me when I arrived home yesterday.
I did not try this speaker in its native habitat. I used it with my Greer Thunderchief head and mounted it in a Mesa widebody 1x12 with open back. The Thunderchief is based upon a Vox AC30 top boost, and can be powered by 4x6V6 or 2xEL34. I'm running mine with EL34 (early-'60s MBLE/Amperex), with a long-plate Valvo '50s ECC83 in V1, and I tend to play my amps clean and chimey. I have two identical Mesa wide-body cabs, and I spent some time comparing with a couple of other speakers in the same cab. I love cast-frame speakers with large magnets, and so this Starfinder appealed to me just by design alone."

"First of all Chris has been a reliable seller since message one; excellent communication, quick at responding and providing solutions to any needs, this is the reason I ordered a brand new custom Rawson Sparfield cab and a DG12 Starfinder chassis speaker. The quality of the product is top notch. I’m very satisfied and I will do business again in the future with him. Highly recommended"
