DRIVE UNITS BY MANUFACTURER:
BX5a CAPKIT
Categories: M-Audio BX5a Monitor Parts

The M-Audio BX5a commonly suffers from power supply regulation instability due the failing of notoriously poor electrolytic capacitors.
Symptoms can include, but are not limited to:
Static sound, crackling, clipping distortion, hissing, buzzing, no bass, loud switch on thump, popping sounds.
This fault is often misdiagnosed with drive units being replaced only to find the fault persists.
This repair kit covers a pair of BX5a and includes 4 specially selected high quality uprated reservoir capacitors for the power supply, no modifications required - we supply an easy to follow step by step photo guide.
In stock for immediate dispatch.
I thought the pair of speakers I found by my bins and had stored for years were broken
But I found Willys capacitors fix and hey presto!
Very happy

I tried this uprated capacitor through sheer curiosity and am pleasantly surprised with the results. So far, and not too many hours in, it’s giving a slightly smoother edge to the top end and has solved an issue I had regarding some hardness to the sound. I’m impressed enough that I’ll look to replace the mid range caps in the future.
I came across some info that after many years these old B&W P4's tweeters degrade. As I grew older, (with reduced hearing of course), I never noticed this gradually deterioration over the years. So I bought the replacement tweeters from Willy's which was picked up just a few days later in Norway. They were mounted in 30 minutes,.. and what a change! My HiFi sounds as a new set. Thanks!
New Foam covers supplies by WHF have completely changed the appearance- they look brand new! Great quality foam, very reasonably priced and quick delivery. Delighted with they now look and sound - will hang on to them forever now.
Excellent upgrade, works perfectly with the speakers it's just soldier and play, they takeaway the over intensity of the original tweeters.
I've had my Mission 734s for about 30 years and for the last five or so the bass units have been falling to pieces. I was about to take the speakers to the tip, but didn't have the heart knowing how capable these used to be. I did a little internet research and these Monacor replacements appeared to do the job. Next day delivery from Willys was impressive, as was the killer sound once the replacements were fitted (which was a simple job). I'd forgotten how these speakers make the windows rattle. Very happy customer!
