Spoke to Willy's regarding replacements for my Mission 737R speakers. Advised these would be ideal with a little modification to my cabinets. They arrived next day and needed very little work to fit. Sounds superb!!
Thanks Willy's l highly recommend your company.

I used these two speakers to replace the woofers on my Accoustic Research AR-6 speakers. One of the AR-6 units had developed a fault so I purchased two to provide a matched set. The ordering process was very easy via the website and delivery was fast. The Monacor speakers were well packed and replacement was easy.
I'm happy to report that they perform very well and my trusty AR-6 speakers sound as good as new.
Many thanks to everyone at Willy's Hi-Fi.
Thanks for the review Kenneth !

Hi Will,
I just wanted to say how happy I am with the replacement mid/bass drivers that you supplied for a pair of Mission 700 speakers that I was refurbishing for a friend. Very well packaged, perfect fit, sound fantastic and cheaper than anywhere else!
It is probably unfair to compare the original mission drive units to these replacements but the difference in build quality and sheer bulk of the new ones is impressive. They sound awesome!
My mate is very impressed and so am I. The only downside is that I now miss the Mission 770s that I sold back in the 80s!
Great service,
Thanks so much,
Nigel Darling.
Thankyou for your review !

Been looking for a supplier of replacement drivers for some years.
Willy's HiFi had just the parts at a good price and they arrived in a couple of days.
Excellent service. Even a personal thank you hand written on the invoice.
A quick delivery and the tweeters are perfect on my mission 753 freedom speakers. Easy to fit . Highly recommend.
I’m no expert when it comes to speakers, but after some research (and a strong recommendation from ChatGPT), I went with the SB Acoustics SB65WBAC25-4 as a reference full-range speaker in this size range.
Having now tested them, I can confidently say they’re probably the best speakers I’ve ever owned. The clarity is outstanding—every detail comes through with incredible precision. The bass is surprisingly full and punchy for a speaker this size, and they handle power impressively well. For anyone looking for a high-performance compact full-range driver, these are hard to beat.
Item as described and arrived quickly - and did the job. However, I suggested that anyone replacing speaker foam makes sure they have a very large pair of sharp dressmaking scissors as it was not easy cutting to size without producing a ragged edge (which I managed to hide short of a close inspection)!
