"www.class-d.com" experiences ?

FUCHSAUDIO · 26th June 2010, 04:31 PM

Looking to get a high powered subwoofer amp in modular form. Despite the web name, these amps are not class-D, but are mosfet based. ANyone have any experience with the company or their products ? The technical data is a little limited on the website, which is a little frustrating.

Class D

The modules are good value, but for sub use you would be wise to pick one that is rated higher power than you need.

Thanks ! I was curious about reliability, sound quality etc. They seem nicely executed, compact etc.

I always though that was a bit devious if they dont just sell class d amps.

Have placed an order with more than 1 month ago, but no replay fm them (I sent 4 emails) and no answer on phone.
Have anybody any clue what is going on with class-d.com ?

I was able to glean this bit of info from their website: the modules use Alfet lateral Mosfets. More info on these can be found at
Magnatec. ALFET Lateral MOSFETs

The two modules also turned up here:

Class-D is listed as a partner of www.proaudio.ltd.uk on this page
http://www.proaudio.ltd.uk/partners.html
The websites for two partners listed are dead links. Seems like the ship is sinking...

Workhorse,

I had a search on this forum and internet looking for ¨Mike Soppelsa and its fraud¨.
I don´t know what you mean by ¨fraud¨, but all my previous orders have been honoured in time.
If you have something to say, please say loud, clear.

As class-d still do not replay to e-mails or phone, I wonder if anyone else have some info about them. Maybe they are facing some ... unwanted problems and we should wait quietly until things return to normal.

Regards,
Tibi
