D2905/970000
Categories: 0.75 - 2" (19-50mm) Dome Tweeters Scanspeak Tweeters
The Scanspeak D2905/970000 has a high power handling of 225W and a frequency response to above 30KHz. Features include a hand coated 25mm soft textile dome, an airflow optimised copper capped pole piece and a tuned rear chamber with an integral resonance damping plug.
This tweeter also benefits from the Scanspeak SD2 'Symmetrical Drive' system incorporating a copper capped and sleeved centre pole piece; this effectively forms a very low impedance shorted turn (called a Faraday ring) within the magnet circuit, the net result being that the voice coil impedance remains largely constant across it's operating frequency range resulting in a more linear output with greater top end extension.
This is a highly advanced design with a sweet, detailed sound. Found in many high-end designs and is a top choice for DIY high performance loudspeakers.

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)!
