As I appeared over SVS’s line of all-new 4000 Sequence subwoofers I used to be drawn to the SB-4000 principally as a result of it is a sealed design, not ported. Sealed subs sometimes have sooner, extra cleanly outlined bass than ported subs. So I had a very good feeling concerning the SB-4000 even earlier than I heard it.
One factor’s sure: it is huge. The cupboard measures an imposing 18.3×17.8×20.9 inches (that is 465x453x530 millimeters), and it suggestions the scales at 102.Three kilos (46.4kg). The SB-4000 incorporates a 13.5 inch (343mm) woofer with an Eight-layer aluminum Three-inch (76mm) voice coil and a 1,200 watt Class D amplifier.
Connectivity runs to stereo RCA and XLR inputs and outputs. There is a SVS Bluetooth DSP management app for iOS and Android units with quantity, parametric EQ, low cross filter, part, polarity, room acquire, customized presets and system settings. I like the big, easy-to-read show on the highest of the sub’s entrance baffle. The SB-4000 sells for $1,500, £1,799 or AU$Three,199.
It is huge for a cause. There isn’t any manner a smaller sub might match the SB-4000’s low-end fury and bass finesse. In the event you love bass however by no means skilled what a terrific massive sub can do, you are actually lacking out. The distinction is important.
So it isn’t nearly bone-shaking energy, the SB-4000’s deft management and dexterity have been obvious in the way in which it synced up with a pair ofmonitor audio system and a Sony STR DN1080 AV receiver within the CNET listening room. Utilizing a small speaker like this makes further calls for on huge subs when it comes to mix. Can a giant sub’s woofer seamlessly meld with the speaker’s 5-inch (127mm) woofers? The SB-4000 had no drawback in that space.
I set the STR-DN1080’s bass administration crossover to 100 Hertz, and adjusted the SB-4000’s quantity stage for a couple of minutes. That is all it took for the sub and audio system to make lovely music collectively. Watching dwelling theater with simply the 2 audio system was additionally spectacular.
First up, I performed Kraftwerk’s stellar “Three-D” Blu-ray and the synth pop pioneers’ music set the room in movement. The SB-4000’s bass was deep and highly effective, bass transients have been fast, and there was no thickening or bloat. I’ve by no means heard bass like this within the CNET listening room!
Then I performed Mickey Hart’s “Dafos” percussion CD at close to realistically loud quantity, and once more the SB-4000 made the magic occur. The drums and percussion’s impression and dynamics have been visceral. There was a palpable texture to Bobby Vega’s electrical bass, which was nicely served by the SB-4000.
Because of the proper mix with the 3020 audio system the SB-4000’s bass appeared to come back from the audio system, not the sub. Massive as it’s, the SB-4000 disappeared as a sound supply.
I moved on to recordings that did not make huge calls for on the SB-4000. Once I performed Spoon’s “Sizzling Ideas” CD, the sub helped the 3020 audio system challenge a bigger and deeper soundstage. I examined it additional by turning off the SB-4000 and working simply the 3020s. Instantly the sound area appeared markedly smaller. Then turning on the sub did not simply add extra bass, the SB-4000 enlarged the soundstage. I’ve famous the identical impact with different top-quality subwoofers through the years.
I additionally watched a couple of films, “Gravity” and “The Revenant.” The 3020s and SB-4000 subwoofer mixture demonstrated the enchantment of stereo dwelling theater for smallish rooms. After all the SB-4000 can be even higher when matched with higher audio system, theor towers can be stupendous with the SB-4000, for instance.
The SVS SB-4000 is a reference-grade subwoofer that does not merely dish out room-rattling dwelling theater results, it is also a really musical sub. I extremely advocate it.
