PSB Unveils SubSeries 450 Subwoofer at ISE 2016

PSB’s SubSeries 450 subwoofer from PSB was introduced today at ISE 2016 in Amsterdam. The new model claims a spot at the top of the sub lineup at PSB Speakers. It sports a 12” woofer driven by a DSP-controlled class-D amp designed by PSB’s sister brand, NAD Electronics.

The SubSeries 450 combines a 12” woofer—featuring a 50-ounce magnet, 2” voice coil, and 6” spider—with dual 10” passive radiators. According to PSB, the new sub is a glossy black 16” cube that offers flat response all the way down to 20 Hz at high SPLs.

One of the key features of the new sub is the inclusion of an NAD-designed amp. It uses a “massive” switch-mode power supply and class-D architecture licensed from Hypex to deliver 400 watts (RMS) power with 1000-watt peaks. PSB says the new amp offers extremely low distortion as well as a high damping factor, with plenty high-current power on tap.

A sophisticated DSP processor is in charge of making sure the sub performs at its best at all times. DSP provides the SubSeries 450 with a crossover that’s closer to ideal than what’s achievable with analog circuits, and it ensures the sub digs deep with low distortion. Furthermore, the DSP makes sure the sub doesn’t overload when it’s working on the lowermost frequencies, which require lots of power and cone excursion to reproduce properly.

PSB’s new flagship sub was engineered by Paul Barton at Canada’s NRC (National Research Council) facilities, which has been his stomping ground since the 1970s. According to Paul, “The SubSeries 450 was designed using the same proven methods that PSB has employed for decades. The result is a subwoofer that is powerful, precise and truly exciting to experience.”

According to PSB, the SubSeries 450 is the most advanced subwoofer the company has ever produced. It will ship in March 2016 and the MSRP is $1500, and I can’t wait to hear it.
