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.
