These are the speakers I had in the PBT Z that was buggered early this month.
In-Phase XT62 6.5" 2way speakers (directional tweeter) that were on the rear shelf. Max power 240w.
The fronts are also In-phase but separate tweeters, similar spec. The fronts had templates made of acoustic boarding that mounted to the door and then to the speaker. Tweeters also In-Phase but can't see any info on them.
I had this lot plumbed into a 400w In-Phase amp and a Nakamici head unit and the sound was... impressive.
Postage would be £6, make me an offer.
