1723 – Tower2019-02-20T13:58:20+00:00

The 1723 Tower and 1723 Tower S 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.

“Arendal Sound has managed to shrink the loudspeaker a lot without losing dynamics, sound signature and the great soundstage. An impressive loudspeaker!”
Håvard Holmedal, Stereo+

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!

PREMIUM
BUILD QUALITY

Higher density and naturally better damped than MDF (Medium Density Fiberboard), using HDF (High Density Fiberboard) results in a sonically inert cabinet. We use no plastic parts.

WAVEGUIDE
TWEETER

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

MASSIVE &
CLEAN BASS

The 6.5” and 8” woofers in the 1723 series are built upon the same core fundamentals as the the 13.8” subwoofer, but with application specific details changed.

1723 Tower S THX: You read the reviews and they all gush about how good the speakers are but you can’t listen to them before you buy, but you take a risk, is the risk going to be come out well?
For me the answer is yes yes yes oh and yes. They are quite simply outstanding speakers. From ordering to delivery to the UK it took 1 day, yes thats right 1 day. This was partially as they were ordered with a sub so you get express UPS shipping but still, that is amazingly quick.
They are very heavy and the design of the boxes meant they were safe inside even after the shipping. Once out of the box you see that everything continues to exude quality with every touch. The speakers themselves come wrapped in silk bags with a soft interior, even the covers come in a separate cloth bag of their own. Open the spike box and guess what everything is laid out and each item is in a bag of its own or cloth individually wrapped. The thought the feel of just putting the feet on is an excellent process that just makes you smile. The engineering and the thought of every element of the speakers even down the packaging is second to none, even Apple would blush.
I started off by putting some Adele tracks on, her voice was like silk pouring out of speakers, detailed and so smooth, bass was rich and deep on tracks like rolling in the deep, way way fuller and more controlled than the KEFs I demoed recently, they sound sooo much better than the KEF R700s its crazy, I suspect R900s would struggle to keep up as well, the new R series will have to be MUCH better to even get close.
Listening to something like Sam Smith and Prey, oh my where did that bass come from early in the track, it sounded completely different, dynamic beyond anything I’ve head before. He then started to sing and it was like he was sitting between the speakers singing, an amazing feeling if you closed your eyes. The sound stage is equally as wide and full as the KEFs I had before but the separation of the sounds moving across the speakers was on another level, layer upon layer of sound.
For movies they are amazing, full dynamic and wide soundstage make sounds fly across the front, bullets in the likes of Saving Private Ryan are a visceral affair. They go so low at one stage I forgot to power my old sub up and hardly noticed the bass is that good.
Overall the risk was worth taking and then some, all of the amazing reviews are right they are indeed breathtaking speakers worthy of the praise heaped upon them. 10/10

1723 Tower THX: “Dear Jan Ove, thank you for your fruitful and fast Support on my request regarding an recommendable amp ! I really appreciate fast Response as Service is one very important part of Business. When i started placing my Towers i felt that my current living room of 25 m² could be too small to enable the Towers to perform perfect, i Need to say i’ m short before moving to a bigger appartment with a 45 m² living room and therefore choosed this powerful product . Meanwhile i found perfect Setup for my small room. Arendal recommends 50 hours “Einspielzeit” to get them work the best. I guess, this is quite true and even after hundred hours i feel they Sound more accurate even in bass and spatial Sound. I connected them Bi-wiring and see more brilliance and depth in voices and brass. But this might depends on your Setup and preference. What i really appreciate is the ability to build an warm and atmospherice Sound Picture even when listening in the night on low volume. There is no need to increase volume as it is with many other products to get an impressive bass. Bass is more warm and full than dry and hard from my Point of view but easy listening is guaranteed and i really don’ t miss precision in any frequency. I used different amps and must say that a clear difference in Sound is hearable. This difference does not appear that clear on other Speakers. So for me it’s a sign of the honest character. Towers are not creating sonic mash, but they Show differences in electronic components and cables. Well done ! Even Bootsy Collins and Marcus Miller as bass Players have no Chance to get them sound strained or stressed. It’s really impressive they produce a nice roomy Sound. And there is no real need to remain seated in the sweet spot. Gettíng seated will also be hard when it Comes to Dance Music, memories get awake of the 80′ s with soulful R&B on the Dancefloor. Currently i use towers as a closed cabinet, it works quite well in the small room. But i`m hardly looking forward to let them perform much harder when they it comes to play in my new home 😉 There might be more analytical Systems on the market, but the total design enables to enjoy all Kind of Music also with lots of Chances to move your feet. Thank you and well done Arendal Team !
