1723 THX Series

The 1723 Series is the culmination of years of design, analysis, testing and listening. 1723 is the Arendal Sound statement of intent to deliver a quality of design, materials and fidelity at prices the market has hardly seen. There are no corners cut in material specification, whether you can see them or not. Where others disguise steel with gold, we use rhodium plated copper. Where others use plastics, we use machined aluminium. Where others skimp on cabinet thickness, we went thicker and then up-spec’d to high density panels. We did all of this, because it delivers better audible results.

Speakers of such capabilities as the 1723 Series need an extremely dynamic sub-bass foundation, and so we developed four subwoofers, all sharing our 48bit DSP controlled Avalanche DSP plate amps and our own proprietary 13.8” sub-bass driver.

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 ahead 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.

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!
