    SPH-210 Upgrade

    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.

    Thanks for the review Phil !

    AR-6 Speaker Upgrade

    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 !

    Better than the original!

    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 !
