Custom built 2.5 way lineup of bass drivers

1723 Tower THX

Based on 46 reviews

The 1723 Tower features a completely custom built 2.5 way lineup of bass drivers, mid bass drivers and waveguide tweeter you cannot find anywhere else. Our HDF cabinets, thick crossover PCBs and ancillary parts, feature engineering detail you will not find at anything like the price. You will find no plastic parts, even if we could have used them to keep costs down without affecting sound quality.

This speaker is for you if


you want high-end, reference floor-standing Tower speaker, for Stereo and Home Cinema applications


you have a big room above 30m²


you want full-range sound without a subwoofer

1723 Tower is physically too big, or do you have a small room? The 1723 Tower S is the perfect alternative. If you need even 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 with an added subwoofer.

Enclosure tilt

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



    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 8” woofers in the 1723 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.

  • “The level of clarity – I was moved to tears almost, listening to some of my classics and favorites.”

  • “This system will make an incredible home theater setup.”

  • “This speaker absolutely delivers and it crushes the competition.”
