The 26mm textile dome has a wide roll surround and is critically treated providing a flat frequency response extending to an incredible 30KHz. The off-axis response and wide dispersion characteristics set a new standard.
The unique AirCirc Magnet System comprises 6 Neodymium magnets mounted in a ring formation within an air flow optimised rear chamber; the result is the elimination of reflections and resonances that compromise the performance of traditional motors systems.
Precision machined to tight tolerances, this is a beautiful state of the art drive unit.

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!
