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 !

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)!
