Mission 733 fit

These are a direct fit and sound amazing in the newly fitted foam damped cabinet.
While I had the drivers out I put some time into adding foam, and it's tightened the bottom end up a little.
Really pleased with the quality replacements and definitely worthwhile to give the Missions a new lease of life.
Good quality. Good value.

Thanks for the review !

73LF 58W

This is the second replacement speaker I have purchased from Willys Hi Fi. As before, speaker was delivered within a few days and was well wrapped. Dead easy to fit as advised. Thanks again.

Perfect replacement for 73-LF58W Mission 733I Bass/Mid Speaker

I love my old Mission 733I speakers and was sad when the original bass/mid speakers dried out and began to crack, a common issue. So was delighted when I came across these as a replacement. As mentioned by others, these are very easy to replace, about 10 mins and then your up and running. I would also like to mention the speed of delivery, very quick and very well packaged. A massive thank you for offering a solution to keep my speakers going for many more years.

Thanks for the review Sean !
