1723 – Subwoofers2019-02-21T09:31:02+00:00

Speakers of such epic capabilities as the 1723 Series need a sub-bass foundation of extraordinary performance and so we developed four subwoofers, all sharing our 48bit DSP controlled Avalanche DSP plate amps and an astonishing 13.8” sub-bass driver. We couldn’t find a driver we liked, so we did it the hard way again!

A single 13.8” driver and Avalanche 500DSP together would make a range topping subwoofer of prodigious, low distortion capability, but for us, that’s just the little one – The 1723 Subwoofer 1. Subwoofer 1.5 is simply a Subwoofer 1 on steroids. Same driver. Same amplifier with unique DSP tuning. HDF enclosure, but with a high precision slot port. It’s just scaled differently to offer another solution for our customers.

1723 Subwoofer 2 doubles up both, with a dual side mounted, force cancelling driver array and doubles the Avalanche 1000DSP power to 1000W RMS. Utilizing a cross coupled invert power supply, we use the negative and positive power supply rails to deliver maximum current to each amp module independently, coping without strain on sustained real-programme dynamic peaks.

Then we went mad and made the 1723 Subwoofer 3. Using the same drivers and amp as the Subwoofer 2, we made the cabinet bigger and slot loaded it for maximum output tuned to a -3dB point of 17Hz. Not for those of a nervous disposition.

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.

DUAL 13.8″
WOOFERS

Why 13.8”? The 25% larger surface area, when compared to a 12” driver, yields a woofer that requires less excursion and power to achieve the same SPL levels.

Honestly, the best subwoofer I have ever had.

5.0 rating

1723 Subwoofer 2: Superb finish quality, outstanding sound with lots of impact, agile and natural. I am very happy with the best subwoofer I have ever had (previously I owned 8 of subs). Now it is time that I understand how the lows must sound. Music? Movie? Anything goes extremely well, even any of music genre. It is the easiest subwoofer for the integration I previously owned. Twin driver system makes it possible to move anywhere you can or want. For the price I cant even discuss further as in the price range you wont find better with the specifications like this, extremely long warranty and the option of buy and try for 90 days. I am not advertising to buy it, I am saying that this subwoofer and buying conditions are the best for me, living in Europe. Buy, try and you wont regret, believe me. It would the part of your life – decor, table with the vibration free enclosure (yes, exactly, no vibration at all even you go with volume as high as you can afford/tolerate), the bass that fulfills your room, your house. The feeling of low ends surrounding makes me happy and surprised every time I switch it on.
Thank you, L-sound/Arendal sound team for a support you gave me during the decision and integrating the lovely black box into my house.

Big upgrade!

1723 Subwoofer 3: The AS Sub3 gave me a big upgrade wen I went from Kreisel 12012. I used to have 2 12012 stacked, but recently sold one. I am pretty sure one AS Sub3 beats my two 12012s. (Its been a white since I had two Kreisels, so dont arrest me if I am wrong.) It delivers physical deep base, and hard punch in movies. Its also naturally in music. I have not used it so much yet, so I guess it will open up even more and give me even more joy! 🙂
