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.
