PL14WJ-09-08
The Vifa PL14WJ-09-08 is a one of the smoothest sounding 5" drivers ever manufactured. This long term favourite was first produced in the 1980s and remains a benchmark performer with an unusually smooth usable output to over 7 kHz. Featuring a damped pulp cone, magnesium chassis and powerful vented magnet system, this 5" / 149mm unit is very easy to work with - crossover modelling is straightforward.
This high quality drive unit is now made by Scanspeak in Denmark using the original Vifa tooling.

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)!
