DRIVE UNITS BY MANUFACTURER:
Fountek FW168
CURRENTLY UNAVAILABLE.
The Fountek FW168 is a 168mm / 6½ inch midwoofer featuring an anodised aluminium cone, a strong diecast chassis and an alloy phase plug. The frequency response is smooth and held within 3db limits between 200Hz-4kHz, this is an excellent result for a drive unit in this price range. As to be expected from an aluminium cone drive unit, the transient response is excellent and distortion is low.

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)!
