Just as expected. Works perfectly as a subwoofer @400Hz in a mono bi-amped active internet radio set up in my study. Thanks!
Thanks for the review !

I paired these with a Vifa/Peerless XT25 tweeters (there is a review on the tweeter) and was mildly surprised and pleased with the result.
The aim was to find a driver that could fit in a small cabinet and not sacrifice too much bass response, these fit the bill perfectly.
Took a while to get the crossover right, but once that was sorted, these really do have a nice sound, Better than nice in fact. I ended up with an incredibly flat response and a very pleasing articulate clean sound. Nothing stands out and nothing is missing.
Do these need a sub? Yes if you really want to delve into the depths.... But with a bit of room gain, (get them closer to the walls), these still sound controlled and smooth and would make a perfect small stand mount or even studio monitor.
I am not aware if these drivers are a replacement for anything out there, but as a DIY speaker, they are very good and easy to mount as they already have a nice beauty ring.
At some point I'll get round to trying the 5" and 8" versions...... :)
Thanks for the review !

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!
