There is a new high-sensitivity folded horn speaker kit being offered by Madisound. The new BK-12m is a single-driver folded horn speaker kit that follows in the lineage of the BK-16 and BK-20 designs. The BK-12m uses the Fostex FE126En full-range speaker driver in a custom folded horn enclosure while the driver is run full range with no filters whatsoever. The Fostex FE126En driver is 4.7" (120 mm) in diameter with a rated sensitivity of 93dB/W(m). This high-sensitivity means that the BK-12m speakers will be suitable for use with low powered amplifiers.
