73LF 58W - Mission 734 replacement (Monacor SPM-165/8 Midwoofer)

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.

Enjoying my Mission 733s again!

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!

Replacements for Mission 734i mid-woofers.

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 !
