Categories: 0.75 - 2" (19-50mm) Dome Tweeters Scanspeak Tweeters
High Performance 1" Tweeter featuring a tuned and damped double rear chamber, giving a low resonant frequency of just 850 Hz. The voice coil / gap is filled with low damping ferrofluid for cooling / thermal stability without affecting the transient response; the voice coil is terminated with tinsel braided leads.
Used in PMC models: GB1, FB1, TB1, TB1S, TB2, TB2S, DB1, DB1S. Also suits some early ATC designs.
This tweeter directly replaces the Vifa D27TG-35-06 and is manufactured in Scandinavia. Capable of excellent results and great value.

I always knew that Linn should never have stopped using Hiquphon tweeters. What I don't know is why it's taken me thirty years to fit a pair in my old Kabers. It's often hard to describe sonic character ....but to pinch Linn's old line from back in the day ...they're Simply Better.(even straight out the box with soldering iron still warm)
As my Kabers are passive,I had been a little concerned that the the 8 ohm nominal impedence of the OW1 would mess with the crossover slope. I needn't have worried....if its shifted the crossover point its much for the better.
Warm thanks also to Will and Caroline for a service in keeping with the outstanding quality of the Hiquphon product.

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.
