C30-6-358

The C30-6-358 is a 30mm tweeter with an ultra hard (Sapphire) ceramic dome in a 58 mm cylindrical body. This tweeter is the big brother of the C25-6-158 .
This audiophile Cell Concept tweeter utilises a special clamping technique that provides easy and discrete mounting to frontplates / baffles; for full details please download the mounting datasheet from the bottom of this page.
A unique FEA optimized underhung motor system with vented aluminium voice coil former and double neodymium magnet guarantees low energy storage, excellent heat transfer and high excursion capability for low power compression and ultra low distortion around 0.07% @ 2.83V and 0.5% max. @ 110dB. The new designed soft fabric surround centers the moving parts with unrivalled linearity.
The dome breakup is above the audible range and well controlled, no dome aperture cutouts or further damping is required.
We recommend a crossover frequency above 1800 Hz.

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!
