They are that good and it is just that simple. It seems that all the praises about Arendals are well deserved.
iiWi Reviews1723 Tower THX
Custom built 2.5 way lineup of bass drivers
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.

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

Spikeskit
High-quality steel bars and premium spikes. Washers are also included to protect your wooden floor.

The premium feel
Magnetically fastened steel grills, wrapped in premium cloth for a smooth look. A “thump” and the grill is snapped onto the gorgeous HDF cabinet in premium paint.

Tune your bass nirvana
Massive bass. Massive ports. Tune your bass to your liking. Three (3) ports make four (4) different variations including sealed for optimized dynamics.

Enclosure tilt
Enclosure tilt at 2.5 degrees for the best soundstage in the listening position. It looks cool too.
Professional reviews
This speaker is truly a high end speaker in every regard possible and is none like other affordable products I have reviewed on this channel.
Jay's iyagiThey may be some of the best looking speakers I've seen in a while
Tha_villamanIf you're looking for a pair of speakers that show remarkable agility both in music and movies, 1723 Tower THX is a brilliant choice.

THX Certified
All our 1723 speakers are Certified by the very strict testing protocols of THX Ultra where each speaker must pass a set of 400 measurements. The THX Certification does not mean it is a dedicated home speaker, but rather a guarantee of tight consistency within well-established acoustic parameters. THX Certification is as much about music, as for movies.
The engineers at THX Labs utilize a proprietary scientific testing methodology to ensure the highest audio fidelity possible. All 1723 speakers passed the THX Ultra Certification without any change to the products, meaning our standards already exceed THX Ultra level out of the box!

Frequency response
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.

Polar response
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.

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