1723 Subwoofer 1.5

Legacy product

The Subwoofer 1.5 shares all of the same high-quality components, design, and build-up as our award-winning subwoofers in the 1723 Series. 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. Subwoofer 1.5 is equipped with a 13.8” driver and the Avalanche 500W amp with its massive power supply. The enclosure is big and ported, which can also be sealed for those who want the edge in extra dynamics over sheer depth. Subwoofer 1.5 can deliver massive performances in movies, with real attention to detail and nuance in music. Movies or music. Perfect for both.

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.
