DRIVE UNITS BY MANUFACTURER:
10F/4424G00
UK STOCK ITEM
With top notch design and high quality component parts, this is a really good small drive unit from the Scanspeak Discovery range. Features include a glass fibre cone, copper capped pole piece, compact diecast chassis and a large Neodymium magnet system. The sensitivity is quite high at a shade under 90dB - this is a good figure for a driver of this size.
Use as full range in small reflex enclosures or as a very fine midrange in larger designs ~ there are many possibilities.

Excellent customer service
Quick dispatch
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)!
