I just purchased a HSU Research ULS-15 MK2. Will eventually buy another but have a few other pressing things and also the holidays. I have been using a B&W ASW 1000. It is a 12 inch ported subwoofer with a 120 watt amp. What can I expect going from one to the other in terms of the biggest differences?
According to B&W these are the specs:
Frequency Response: ±3dB 25Hz - 40/140Hz adjustable response * Low-Pass filter:Active 4th-order, variable cutoff frequency 40-140Hz * High-pass filter (Line level):active 3rd-order at 80 Hz * High-pass filter (Speaker level)
assive 1st-order at 80Hz into 8 ohm resistor (response using speaker level connections dependent on satellite impedance) * Sensitivity: 90dB spl (2.83V 1m) * Design – Magnetically shielded 12” diameter high excursion woofer seated in a Flow-ported 70 liter cabinet with built in 120 Watt powered amplifier * Power output:120W continuous * Signal/Noise:90dB * Input Impedance:22kohms * Functions: Input Level Phase 0/180 -Low-pass filter frequency -1x 300mm (12in) dia long-throw with magnetic shielding * Dimensions: … Height: 460mm (18.1 in) … Width: 540mm (21.3in) … Depth: 500mm (19.7in) * New Weight:30kg / 66lb
