“Its output is taut, and it hits hard but doesn’t linger, which makes it great for kinetic film soundtracks. The Omaha Beach landing from Saving Private Ryan (UHD Blu-ray) lets the PC-4000 strut its stuff, underscoring the explosions with perfectly timed impact but picking up smaller details like machine-gunfire and adding a visceral low-end presence.
I have auditioned SVS’s PB-4000 ported sub and for me, the cylindrical version delivers an almost identical experience but has the benefit of not being the size of a fridge-freezer. In fact, if space is an issue then the PC-4000 might be the ideal solution. And considering the state-of-the-art subwoofery inside, it isn’t that expensive either.”
“Even used with comparatively tiny satellite speakers and a high crossover, bass integration is excellent, although I did find I got better results using a line-level input from my Yamaha AVR (bypassing its onboard processing), than via the LFE feed. My only real criticism of the way the SB-4000 behaves is a slightly odd one. This is a superbly controlled subwoofer, aided by some clever DSP, but there are times when I’d love to be able to make it a little more boisterous. Compared to the GoldenEar SuperSub XXL, which can be persuaded into great hulking slabs of unnecessary low-end if you ask it nicely, the SVS stays absolutely controlled. I’d almost like there to be a ‘Ludicrous’ setting in the SVS Bluetooth app (to join the Music and Movie presets), which I could select when I wanted to behave like a five-year-old.”
“The cabinet construction was very solid for such a large subwoofer. It was very inert. This quality goes hand in hand with the super high quality finish. My review unit was black ash. I normally do not care for black ash but this one is different. To begin with, it’s real wood. Then it is hand-rubbed. The final result is quite handsome and I have no problem keeping it on display in my home theater. I love the look of it as a matter of fact.”
The Monolith 15” THX Ultra holds THX’s “Ultra” performance class certification, which means it should be able to help to present a THX experience in a 3,000 cubic foot room with a 12’ viewing distance from the screen. That is a big space to fill, and the laws of physics dictate that a large sub is needed for that task (or at least a whole lot of small subs). The 15” THX Ultra is such a behemoth that, at a glance, it does look like it might be up to the task, but the THX certification is verified proof, so no guessing is needed. However, the 15” THX Ultra is only certified for that level of performance in one of its operating modes: all ports open and EQ switch set to “THX.” It isn’t that other operating modes will perform significantly worse, it’s just that they don’t have very specific behavior needed to act totally predictable by the THX controlling processor otherwise.”
“Klipsch uses a Class D 600watts power amplifier with an analogue pre-amplifier stage to drive the frontal reflex port loaded 12” woofer. This particular driver/amplifier combination, according to Klipsch, is able to generate an acoustical output level of up 115 decibels and achieve low bass extension of down to 24 hertz. Klipsch also explain that while achieving an extended bass response at a high sound pressure level is a desirable trait and a goal with all subwoofer manufacturers doing so without sacrificing low frequency detail is easier said than done.”
