Downscaled version of the 1723 Tower

1723 Tower S THX

Based on 13 reviews

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.

This speaker is for you if


you desire a high-end Tower for Stereo and Home Cinema


if your room measures up to 35m²


you want full range sound without needing a subwoofer

You are looking for the ultimate flagship speaker for even bigger rooms? The 1723 Tower is the top-of-the-line performer! If you need higher output with lower extension, then we recommend adding a subwoofer like our 1723 Subwoofer 1S or 1723 Subwoofer 1V. The stand-mount alternative is our 1723 Monitor S with an added subwoofer.

Massive bass. Massive ports. Tune your bass to your liking. Two (2) ports make three (3) different variations including sealed for optimized dynamics.

Rhodium-plated copper terminals. The aluminum backplate is precisely recessed for a perfect fit in the HDF cabinet.

Enclosure tilt

Enclosure tilt at 2.5 degrees for the best soundstage in the listening position. It looks cool too.

Mix and match

With a perfect soundstage from all 1723 speakers. Same tweeter, woofers, voicing and premium feel.



    We took a look at what spikes actually do and then applied straight-forward, uncompromising engineering to deliver an effective, attractive solution that doesn’t cost the earth.


    Vented vs. Sealed – Whatever floats your boat!


    Crossover design is a culmination of model, measure, listen, remodel, remeasure, re-listen, all while refining performance in increasingly small steps.


    We are especially proud of our new exclusive and fully custom made grills. For all Arendal Sound speakers we have made a free flowing, perforated metal grill which does not affect sound quality.


    The 6.5” woofers in the 1723 S THX series are built upon the same core fundamentals as the the 13.8” subwoofer, but with application specific details changed.


    The heart of all Arendal speakers, our Tweeter utilizes a 28mm synthetic soft dome with custom designed, matching waveguide.


    Chosen for its excellent conductivity, corrosion resistance and hardness; all serve to protect the copper material and music signal carried within.


    We have customized a new slick puck-design mounted with M6 bolts. They create extreme stability against the floor. Branded with the Arendal Sound logo.

Frequency response does not reflect maximum output but shows its true response in a anechoic chamber. Typically you will see an elevated response in the bass response below 40Hz in room due to room gain, which can add around 6dB pr. octave under 40Hz depending on the size of your room.


The charts display frequency response measured at different angles, the sum of which is referred to as power response. Much scientific research has been undertaken on this subject and a linear power response has proven a substantial impact on the overall sound, because the frequency response is more even in all directions. This means an Arendal Sound speaker will be more tolerant of differences in room shape, size, construction and materials.


The impedance charts are electrical measurements of the loudspeaker’s resistance vs frequency.

Professional reviews

  • I hate to be the bearer of bad news, but if you don’t have good speakers, you don’t have a good sound system. Period. The speakers you use have a disproportionate impact on how your music sounds.

  • “I will definitely recommend the 1723 Tower S THX, if you have the space and don’t mind the size. For the price that you’re paying; the look and the sound of them is hard to beat.”

  • “If you’re in the market for a pair of speakers at this price point, you’d be taking no risk auditioning the 1723 Tower S in your home.”

  • “I never owned a speaker that does so many things so well and gives you this many options to tailor its sound and blend it into a reference grade, cohesive system, and that in my opinion is what makes the 1723 Tower S so special.”

  • Arendal makes extraordinary speakers and subwoofers, there’s simply no other way to say it.

  • 1723 S Towers are a superb choice. These can play very loud without strain and prove that the THX badging is more than just a trademarked logo.

  • What nevertheless impresses is the calm, relaxed and undaunted way it plays music, and that it still manages to render each and every hit of the drums and every single blow with palms and fingers.

  • Arendal Sound has managed to shrink the loudspeaker a lot without losing dynamics, sound signature and the great soundstage. An impressive loudspeaker!
