Categories: 0.75 - 2" (19-50mm) Dome Tweeters Scanspeak Tweeters

DISCONTINUED. NEW REPLACEMENT MODEL IN STOCK : D3004/602200
From the excellent Illuminator range, this 26mm compact soft dome tweeter offers a very low resonant frequency (fs) of just 425 Hz which significantly eases crossover design and broadens the scope of application.
The small size of this unit does not compromise the sound quality; these compact tweeters are fully comparable to the renowned full size Illuminator and Revelator tweeters. Excellent for high quality in-car installations ~ be mindful of the rear chamber depth if considering mounting in the doors; full dimensions can be found in the downloadable datasheet at the bottom of this page.
Ideal for high-end DIY home-built compact monitor speakers and custom in-car applications.

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!
