A good replacement for the 73-LF58W as found in Mission 732, 733, 733i, 734, 735 + many other models.
This 6.5 inch unit features a damped pulp cone, a powerful 80mm ferrite magnet system and a rugged steel chassis. The frequency response is smooth with good midrange control and extension. An ideal replacement unit for many speakers.

4 units bought to upgrade my old cracked Mission 734 speakers.
Arrived a few days later well packaged individually and collectively.
Easily replaced, nice fit, straightforward.
Can crank up to 11 again, if my Daughter allows :-)
Thanks.

Great purchase! No issues with replacing my original, cracked 733 cones. Really happy to take a trip down memory lane & listen to music again through one of my first speaker purchases. Thanks!
Thanks for the review !

These are some for restoration (as are my 735i's that I've had another six of these Monacore mid-woofers sat for too long now...about to do both at last!) so hope they sound great?! The original Mission speakers were some kind of opaque polymer & had suffered some horrible degradation due to time & UV & were un-useable as a result.
The Monacore ones look to be a more traditional card type material cone & their weight seems very comparable to the Mission originals.
A small drawback I've noticed are the mounting holes being in a different position but have bought appropriate screws & some butyl rubber strips, just mark & drill some pilot holes in the cabinets & all should be good, can't wait to see what they sound like!
Thanks for the review James !

Excellent customer service
Quick dispatch
Excellent advice once again from Will so helpful. Bought and installed I was a bit apprehensive about soldering direct to the terminals including the speaker terminals but took my time and with the guidance of will these have transformed my speaker's to a completely different level. Detail clarity is outstanding brings out subtle Nuance's. I'm so glad I replaced my existing crossovers with these they are better than I could have imagined and are excellent value.
Thanks again for outstanding service.

I am a big fan of the linn range of speakers , particularly the Keilidh and Kaber models . They are well designed and extremely well constructed. Anyone thinking of taking the step on this tweeter upgrade I would say do not hesitate.! I have a passive pair of Kaber with the 3bar Linn mk2 tweeters and these are generally accepted as a decent improvement over the early ceramic versions. These OW02 Hiqufon went into my active pair of Kaber and they are in a different league in my opinion!! I am a returning customer to Willys Hifi and always get great service, items arrive on time and well packaged. Thanks for being the go-to website when it comes to thinking about my next project or upgrade! Regards Ianpop.
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!
