The ST4 is designed for
applications requiring greater dynamics combined
with full frequency response. The slender
tower features two separate chambers; the
top portion, which replicates the highly acclaimed
Super Audio SB3
bookshelf system, and the lower portion, which
contains a vented, built-in 8" subwoofer.
This unique design approach provides the sonic
finesse of our finest 2-way bookshelf with
the added dynamics, extended bass and high
output more typical of 3-way systems.
The ST4 is bi-ampable to permit tuning low
frequency response in difficult room placements.
Available in gloss black only, stabliziers
included. Recommended NHT center channel SC2.
