DRIVE UNITS BY MANUFACTURER:
SPH-135C
DISCONTINUED BY MANUFACTURER - ONLY 1 LEFT IN STOCK.
The SPH-135C is a versatile drive unit from the Monacor 135 series featuring a woven carbon fibre cone, vented pole piece and diecast chassis. When mounted in correctly aligned cabinets this long throw unit is capable of reproducing bass that is surprisingly deep and accurate - ported cabinets of around 14 litres can give an in room response extending down into the upper 30s (Hz) which is excellent for a driver of this size.
A fine replacement unit for a wealth of mainstream designs requiring a high quality 5¼ bass driver such as Rogers, Castle, Mission etc. Full details and dimensions can be found on the downloadable datasheet.

Great update to the original Castle drivers which started to crack anround the edges after many years of service.
More bass response and energy when playing rock tracks.
Would note that driver surround is slightly larger than original.
Thanks for the review Ian!

Ordered two of these to replace the original Castle IsIs units as over a period of 35 years the polypropylene cones had gone brittle due to UV degradation, a common occurrence, units arrived in quick time and came securely packed, they took 20 minutes to solder in and slipped straight in, they sound better than the original units as they develop quite a bit more bass something the originals were very light on, very good build quality, and most importantly, a very good sound quality I’ve just acquired a a pair of Castle Avons for £60 that need the same upgrade, I will certainly buy these again from Willys very competitively priced with a quick efficient service 10/10
Thanks very much Willys HIFI

As fit as the old one
Needed to replace my speaker grilles on my (45 years old) Castle loudspeakers. The fabric supplied looks and feels very, very similar to the original grilles and looks the part. just need to find the old Castle badging to complete the look. Feels like decent quality material at a very recent price.
Excellent service from home Willy's as usual and these Scanspeak tweeters proved a perfect replacement in my ATC speakers.
Really pleased with purchase, mic is great. Used for car audio Helix DSP RTA.
Service was excellent, I get the feeling that these guys care. They deserve our money far more than A****n....
I bought a pair of Dayton Audio crossovers for my Mordant Short M20's speakers, to replace the cheap stock units, and it was well worth the cost, sound staging has been transformed from a flat sound to a massive uplift in presentation, only been running for 2 hours, so I'm sure things will get even better over time once the capacitors etc bed in.
Great service once again, arrived quickly, well packed. Thank you.
