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 .

Product as described, easy to cut & fit.
On reflection having now fitted the foam, I wish it was 15mm to 18mm or even 20mm thick. This is not a complaint. For a small speaker under 30cm high it’s perfect. For a larger speaker I feel a thicker sponge would hold its structure more pleasingly, its aesthetics, but important for the finished look.
I’ve been building my own home cinema as a complete DIY project and reached the stage where I needed some decent acoustic foam for my speaker panels (also DIY!) so I picked up 3 large sheets from here. They were sent quickly, packed well and moreover, are of excellent quality. With them being folded into the shipping box they were slightly creased but after leaving them out overnight on a flat surface, the creases fell out completely. They’re now in place and doing their job brilliantly. Cheers Willys Hifi!
The crossover was constructed well, I just need to figure out the best way to attach it to my Kef Concertos as they are bigger than the ones supplied by Kef that are mounted on the front of the baffle board.
Very nice deep bass look amazing with my custom made speaker
Great speedy delivery and very easy to fit. The plastic in my drivers had perished and they had suffered one too many parties! No need to make any adjustments (someone above did suggest that). I just screwed them in and the foam compressed into place. Before and after below (before I changed speaker number 2). Thank you!
