Used in a DIY LS3/5a project, with Morel CAT 298 tweeters and custom crossovers using ClarityCap CSAs. Super pleased with these woofers! I think they synergize well with the “live” thin-wall LS3/5a cabinets. The sound is neither bloated, nor thin, just revealing, spacious, and with very lifelike tone. I’m so happy with the results of this project and had a great buying experience with Willy’s. Thank you!!
Thanks for the review - that's a great looking project !

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!
