SVS SB-3000 fueled subwoofer

SVS's as of late presented SB-3000 is a minimized controlled subwoofer that is $600 less expensive, a couple cubic inches more modest, and 37lb lighter than the model it replaces, the SVS SB13-Ultra. Its intensifier is less strong (800W versus 1000W), however its appraised recurrence reaction broadens lower: a stygian 18Hz, contrasted with the SB13-Ultra's simply raucous 20Hz.

The SB-3000's recently planned 13" driver has a vented aluminum cone, an infusion shaped gasket and encompass, and a polyimide-impregnated fiberglass previous, encompassed by two 15lb toroidal ferrite magnets. Its new 2" split-wind voice-loop has a lower twisting thickness in the middle, flanked by two higher-thickness winding segments, a course of action said to help low trip at low result volumes however expanded result range for higher result volumes. The driver has four 24-strand silver-plated Litz lead wires woven through the 6.5" 2-handle Nomex-composite insect; larger than average nickel-plated high-pressure spring terminals; and a low-carbon vented steel U-burden and top plate.

The sub's inner class-D speaker, named Sledge, has an advanced front end yet a result segment worked with completely discrete, high-current (25A), 600V MOSFET yield gadgets, for an evaluated 800W RMS and 2500W pinnacle. All application settings, including those for its parametric equalizer, are overseen by an interior high-goal 50MHz Analog Devices DSP chip with 56-digit sifting. The DSP utilizes a "power factor rectification calculation" to diminish current requirements by 30%–half while keeping a consistent 360V DC from the inside power supply. This adds to the sub's effectiveness, empowering it to siphon out 120dB SPLs, a critical increment over the SB13-Ultra's 111dB SPL evaluated yield.

SVS's easy to use cell phone application (rendition 1.3.25, form 20190319), accessible liberated from iTunes (yet additionally for Android and Amazon gadgets), furnished me with remote Bluetooth control from my listening-room seat. Its bidirectional Bluetooth remote connection deals with every SB-3000 independently, regardless of whether they are taken cover behind a lounge chair, controlling volume, low-pass channel recurrence and incline, a three-band parametric equalizer that works over a scope of 20–200Hz, room-gain remuneration (a high-pass channel in the scope of 25–40Hz to forestall profound bass over-burden), presets (Movie, Music, Custom), extremity, and inherent instructional exercises. The application's toolbar shows the two last digits of the chronic number of the sub being overseen close to a Bluetooth symbol, its tone implying the condition of network: green for "on" and white for "off." A base menu offers the choice of resetting default settings, saving to a preset, or clarifying the control include.

For remote sound transmission availability, SVS offers their SoundPath remote sound connector unit ($119.99), wiping out the requirement for normally long, exorbitant interconnect runs. The unit contains a pre-matched Bluetooth transmitter and beneficiary set; the last option connects to the SB-3000's back help board through a USB link. It works at 2.4GHz, utilizes dynamic recurrence choice, utilizes forward mistake adjustment, and has a working scope of 50 feet.

Arrangement

Since the time JL Audio's Carl Kennedy demanded I survey their f113 Fathom subwoofer two by two, I've requested that makers send me two subs for audit. Double subs, I've found, have empowered enhancements in soundstage width and feeling recuperation. SVS's Ed Mullen affirms my impression and records the extra benefits of two more modest subwoofers over a solitary huge unit, including lighter weight, more modest size, more straightforward progression of pedestrian activity, more prominent unique reach, a smoother recurrence reaction across the room, diminished limitation of the wellspring of the bass, less visual effect, and simpler room position.

The SB-3000's almost cubic shape and generally reduced size—15.6" high by 15.2" wide by 15.7" profound—assisted make with increasing for its 54.5lb weight, making it simple for me to unpack and convey the pair, each in turn, up two stairways to my listening room. Diminutiveness and low weight likewise implied that sliders weren't expected to secure the listening room's hardwood floors. I stopped every one of their power strings into my Torus Power RM 20 power conditioner and utilized lopsided interconnects: The SB-3000 and the SVS remote transmitter utilize just RCA input connectors.

I chose first Quad ESL-989s and afterward KEF LS50s to fill in as my nearly full-range speakers: I figured their restricted profound bass reaction and dynamic reach would profit from a subwoofer. Both were situated 68" from my listening position. The KEFs were set on Franklin and Lowell speaker stands (commentary 1), with their tweeters 34" over the floor—similar tallness as my ears when I'm situated in my listening-room seat.

As with most other reseller's exchange subwoofers investigated in these pages, the SB-3000 was intended to be utilized with a sound framework's principle speakers run full reach, so they do exclude worked in high-pass channels. This turned out great for the LS50 on the grounds that its inside hybrid has a 24dB/octave rolloff beneath 52Hz (commentary 2), shielding its woofer from unnecessary profound bass journeys. I additionally tried them with my JL Audio CR-1 outside electronic hybrid's high-pass channels set to 70Hz, 24dB/octave, yet I couldn't identify any significant contrasts in solid quality between the high-pass channel on or off.

In any case, the Quad ESL-989s' bass boards are helpless against harm from exorbitant trips during supported profound bass entries. To stay away from this disaster, while checking on the SB-3000s with the Quads, I generally utilized the CR-1's high-pass channel. (See the sidebar, "Utilizing the SVS SB-3000 with an outer hybrid.")

I additionally explored different avenues regarding remote availability by blending the SB-3000s with the CR-1 hybrid's results through SVS's SoundPath packs and their comparing beneficiary modules. I associated the transmitter modules to the CR-1's low-pass yields with uneven interconnects, and the collector modules to the subwoofers' genuine boards through USB-A links. LEDs on the transmitter and recipient modules gradually streaked red while connecting, then, at that point, stayed consistent, later which the two subwoofers woke up and played. Looking at wired versus remote transmission association, I could hear no distinctions in foundation commotion, bass power, pitch definition, strength, or snugness, and I encountered no quitters of the melodic transmission whenever during this audit. The right-and left-channel SoundPath units didn't meddle with each other, as they did with MartinLogan's remote kit,5 so the two subs could be controlled without separating one and interfacing the other.
