DRIVE UNITS BY MANUFACTURER:
SPH-135C
DISCONTINUED BY MANUFACTURER - SOLD OUT.
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.
Resonant frequency (fs) | 40 Hz | Nominal impedance (Zn) | 8 Ω |

Electrical Q factor (Qes) | 0.43 | RMS power handling | 50W |
Total Q factor (Qts) | 0.39 | Sensitivity (2.83V/1m) | 88 dB |
Equivalent volume (Vas) | 17L | Chassis diameter (pincushion profile) | 133 mm |

Thanks for the review Graham !

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

I always knew that Linn should never have stopped using Hiquphon tweeters. What I don't know is why it's taken me thirty years to fit a pair in my old Kabers. It's often hard to describe sonic character ....but to pinch Linn's old line from back in the day ...they're Simply Better.(even straight out the box with soldering iron still warm)
As my Kabers are passive,I had been a little concerned that the the 8 ohm nominal impedence of the OW1 would mess with the crossover slope. I needn't have worried....if its shifted the crossover point its much for the better.
Warm thanks also to Will and Caroline for a service in keeping with the outstanding quality of the Hiquphon product.

Been looking for a supplier of replacement drivers for some years.
Willy's HiFi had just the parts at a good price and they arrived in a couple of days.
Excellent service. Even a personal thank you hand written on the invoice.
A quick delivery and the tweeters are perfect on my mission 753 freedom speakers. Easy to fit . Highly recommend.
