Darren Jones
Replacement tweeters for 2003 ATC SCM 12’s

The tweeters arrived promptly and packaged really well. For size and fitting they are a perfect replacement for the 55-06 units. As regard to SQ, at the moment they sound a little bright and forward; I’m hoping this will reduce a little as they run in. Maybe my ear is just used to the old OEM tweeters that were obviously quite a few db down after 20 years. Very much looking forward to hearing how they settle over the coming weeks. Thank you.

Thanks for the review Darren !

Great replacement for tweeters in Royd RR2 which had very dried out Ferrofluid and were down a fair few dB. Only minor easy mods required to cutout in speaker undertaken with a file. Well worth it, speakers sounding lovely.

Thankyou for your review !
