Morel TiW 638Nd Woofer
The Morel TiW 638Nd Woofer is a highly advanced bass-midrange drive unit featuring many class leading innovations such as the Uniflow™ Aluminium diecast chassis (designed for maximum undisturbed airflow with minimal rear reflection) and the unique Hybrid™ Neodymium / Ferrite mixed magnet assembly. In common with all Morel drive units, the motor system is superbly engineered featuring a Titanium voice coil bobbin and a large 3" voice coil wound with Hexatech™ Aluminum wire. Hexatech wire has an hexagonal cross section thereby eliminating the air gaps usually found in voice coils.
The frequency response is very well controlled to 4Khz with good off- axis characteristics. Power rating is 150w nominal and can withstand short term peaks of 1000 watts. A full datasheet can be downloaded from the bottom of this page.
Also available in 4Ω - Morel TiW634Nd.

Replaced faulty Studio 0.5 drivers with these. Had a wobble about the fit so called to confirm details and had superb advice. Recommend both the drivers and Willy's!
I've been repairing a set of vintage speakers (Rogers JR149's) and honestly, I wouldn't have been able to do it without components and parts from Willy's Hi-fi! Thanks for the help and advice as well!
Quick shipping and high quality cloth. Very easy to work with and sticks well with contact adhesive. Very pleased with the final look!
Thanks to Will for advising on a replacement for these classic Arcam speakers from the early 90s. Good value and quick shipping. This was a small restoration project on this sealed box design - these now sound punchy, crisp and clear and really fill the room. Tweeters seem to still be breaking in as the detail and imaging just keeps getting better! Looking forward to coming back for parts for the next project!
I needed to renew the foam fabric around my JR149 loudspeakers. Age and UV light had caused them to start disintegrating - not helped when one of our cats decided to assist with her own paws!!
Googled and up came Willy's details. I confirmed that I needed two of the "large" sheets and paid by Paypal. Order promptly dispatched and JR149s cosmetically restored!
