DRIVE UNITS BY MANUFACTURER:
BC25SC55-04
This smooth sounding tweeter features a 4 ohm 25 mm voice coil, high energy Neodymium magnet assembly, a damped textile dome and ferrofluid in the magnetic gap for enhanced cooling of the voice coil. The BC25SC55-04 has a compact cropped faceplate (70mm diameter, 54mm across flats) with recessed mounting holes, and comes complete with a foam sealing gasket to reduce vibration. A finned heatsink aids cooling and results in high power handling for a driver of this size.

Peerless by Tymphany
I have used these with both an active and passive crossover, crossed over at 2.8Khz and 3.2khz (dependent on the woofer).
This is a really smooth sounding unit but still has a lot of sparkle without sounding harsh. I did try it at around 2Khz, but is sounded harsh at higher volume.
Ideally you need to be at least and octave above the resonant frequency, so 2.8khz is a good crossover point for this unit.
Another plus point (from an aesthetics point of view) is that it looks like a more expensive unit than it is. The built quality is good. At just of £32 for a pair you cannot go wrong.
If anyone is interested I matched these up with the Peerless M16NH 6.5" Bass / Midrange in an front ported cabinet. Possibly the nicest sounding budget speaker I have heard for a long time!
Thankyou for your review !

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.
