The 1723 Tower S is a downscaled version of the 1723 Tower.
It features a completely custom built 2.5-way lineup of
mid-bass drivers and a waveguide tweeter you cannot find
anywhere else. The materials, quality, drivers and crossover
components are just the same as you would expect from
any of the 1723 speakers. The only difference is smaller
enclosure with 6.5” drivers in 1723 Tower S, instead of the 8”
in the 1723 Tower. The sheer performance, level of detail and
dynamics delivered by Tower S is unheard of in this price
category. Expect the Tower S to be compared to much higher
priced speakers on the market.
