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 !
