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.

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!
