DRIVE UNITS BY MANUFACTURER:
UW 1258 Woofer
Categories: 10-15 inch Bass Speakers Morel Subwoofers
The Morel UW 1258 is a dedicated 12" very high power, long throw bass speaker from the Ultimate Subwoofer range. This rugged drive unit features the Morel Uniflow™ Aluminium diecast chassis, a high flux double Ferrite magnet and a huge 5.1" / 130mm voice coil assembly wound with Hexatech Aluminium wire. The Accucenter™ self centering pulp fibre cone/cap is a one piece assembly offering high rigidity and excellent internal damping.
This drive unit features PFS™ Progression Field Symmetry: under extreme conditions, the spider and surround are engineered to act as progressive shock absorbers, preventing voice coil displacement and bottoming out - this improves voice coil linearity and maximum excursion.
The pole piece is vented (very large) for minimal compression under heavy drive conditions and power handling is very high at 800W nominal, 3000W short term peak. A full datasheet can be downloaded from the bottom of this page.

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.
