    Cracking little drive unit

    This is a great driver for a transmission line or tapered pipe design. Good quality, if basic, chassis - nice and rigid with a chunky magnet. Nice smooth midrange making it easy to integrate with a range of HF units. I used the Fountek NeoX1.0 Ribbon Tweeter which is similarly an impressive unit. A good combination.

    Thankyou for your review !
