UK STOCK ITEM
The SB26STAC-C000-4 is a 26mm soft dome tweeter from SB Acoustics featuring a 100mm cast aluminium faceplate. The frequency response and dispersion of this tweeter is very good, nothing else really competes at this price.

After discussion with Will and some exhaustive testing , modelling for replacement of Peerless 811815's (DT100H ) in a 3.5 way, finally a tweeter that does the business . Having tried , tested and listened to a mixture of budget units from Monacor ,Vifa and SBA this one gets permanently fitted. It's flat .. really flat when measured and again top QA gives virtually no difference between the drivers received . Listening wise its not as soft as the Peerless ( they still measure flat ) but not as harsh as the Monacor . Positioned offset ( inboard ) on a 300mm wide baffle , crossed at 3K , nil diffraction and came in from 5K to 20 K with LR3 +/- 1dB after a 2ohm post XO attenuation to stop the rise from 10 k up. Off axis performance is brilliant for cone size. A little under 2dB down OA from manufacturers rated FR at 1m .THD measured at < 0.5% at 90dB . Recommended ? Yep .. a great budget buy and certainly a step up from the plastic 'version' SB26ST-C000-5 .. If you are in the market for a replacement 100mm face plate tweeter look no further . Gillette treatment of your ears at volume is not a trait for unit . Hi hats and crash cymbals are handled with aplomb. Partnered with Audyn Q4 caps ( consider 0.1uF bypass caps ). Mundorf Evos work well too if you want to spend the extra and have space .. Tried with a mixture of recordings from James Taylor to Marillion ,exceptional value for money . Top service from Will and team again from order to delivery in 24 hours .
Thankyou for your review Mark !

Since 1991, I've had Linn Keilidh speakers, which I upgraded a year later to an active system using the Linn Wakonda and two LK100 power amplifiers. Over the past few years, I’ve considered replacing my audio setup with a more compact active system. However, the downside is that it would require a significant investment to achieve a comparable sound quality.
In the end, I opted for an upgrade of the tweeters and new speaker covers after more than 30 years.
The upgrade itself went smoothly using the supplied solder. I’m very pleased with the end result. The upgrade has had a noticeable impact on the soundstage: the bass, midrange and treble all have more space and clarity within the stereo image. This first became apparent to me when listening to vocals—it’s as if you can perceive the space surrounding the voice. And the longer you listen, the more this spatial detail stands out.
I’ve turned the amplifier up slightly, as creating that sense of space seems to require a bit more power.
It’s an upgrade I can definitely recommend.
Wow, just had my Mission 753 upgrades of crossover and also tweeters. What a difference it’s made! The high frequencies are more refined and OMG, the separation and richness of mud and bass if awesome…..much thanks to Willy’s for giving my 753’s a new life 😀😀
Excellent advice from will as usual and exactly what I wanted. These have improved the sound of my current speakers and taken them to another level. Sounds superb I can hear tonal difference's between things that I never heard before. Superb bass drivers dig so deep.
As usual will has been outstanding.
Brilliant to deal with always helpful and gives great service.
What a brilliant capacitor, from first listen exceptional clarity and depth. Bargain will be buying more.
