As I’ve mentioned elsewhere on this site in the past, I normally run no less than two subwoofers in my main media room, not for increased output, but rather to fill in some unavoidable dips at around 45Hz (with a sub on one side of my system) and 80Hz (with a sub on the other) caused by the geometry of my listening space. Given that I knew I would only be receiving one Defiance X15 for review, I disabled one of my reference subs beforehand and spent some time listening with only one sub, so as not to create an unfair comparison. In the end, I positioned the X15 on the left side of my system, if only due to the fact that it’s too wide to fit in the subwoofer spot on the right side. It is, after all, nearly three inches wider than my reference SVS PB-4000, which is itself snug as a bug on that side of the room.”
The best placement for a single sub in my room gives me a relatively flat response for an un-EQ’d single subwoofer, with a window of +/- 4 dB from 25 Hz to 100 Hz with no broad dips in important ranges. This location trades low-end room gain for a relatively flat response, a worthwhile trade for my tastes. The receiver used was a Pioneer Elite SC-55 and the crossover was used mostly at 80 Hz. I set the Defiance subwoofers up in a manner where I could easily switch back and forth between them, and also in placements right next to each other to minimize the difference of the acoustic effects of the room between them.
As always, I will note here that since room acoustics have a huge effect on low frequencies, the way these subwoofers sound in my room at my listening position is not necessarily going to be the way they sound anywhere else for anyone else, so readers would do well to keep that in mind, and not just for this subwoofer in this review, but for any subwoofer in any review.”
“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.”
