The 1723 Surround S is a downscaled version of the 1723
Surround. The materials, quality, drivers and crossover
components are just the same as you would expect. The only
difference is smaller enclosure with 6.5” drivers in 1723
Surround S, instead of the 8” in the 1723 Surround. Using
the same 6.5” mid-bass driver and waveguide tweeter on the
front baffle as used in the other 1723 S models, excellent
tonal matching is assured. To deliver an all-enveloping
surround field and assist in peerless surround steering, we
fitted custom built 4” full-range dipolar drivers to the angled
side baffles into our TriAxial speaker. The 4” surround drivers
are imported straight from the original 1723 Surrounds,
as this driver is optimal for the task, regardless of the main
driver size. The sheer performance, level of detail and
dynamics delivered by the Surround S is unheard of in this
price category. Expect the Surround S to be compared to
much higher priced surround speakers on the market.
