The 1000 Pro subwoofer series of the American company SVS, which replaced the usual thousandth, has so far included only two models: SB-1000 and PB-1000 . The first is in a closed case, the second is in a phase inverter (two ports). Otherwise, they are practically twins.

The 12-inch long-throw speaker of the new "thousandths" received a fiber composite cone with a parabolic suspension. The driver is equipped with a double ferrite magnet and a double-layer voice coil.

Both 1000 Pro models feature the Sledge STA-325D amplifier. It combines the high output current of discrete MOSFETs with class D energy efficiency. Its 325W RMS power can peak at 820W or slightly more.

The signal to the amplifier is processed by a 50 MHz Analog Devices audio processor with 56-bit filtering, which SVS described in a press release as "the most advanced DSP available in a home subwoofer."svs sb 1000 pro vs pb 1000 pro

The SB-1000 and PB-1000 cases received additional inserts made of high-strength plastic and non-resonant elastomer feet. Both subwoofers can be covered with a solid fabric grill.

SVS SB 1000 PRO

The SVS SB 1000 Pro subwoofer is based on the powerful Sledge STA-325D amplifier, the output stages of which are made on MOSFETs capable of providing high output current. The amplifier delivers 325 watts of continuous power peaking up to 820 watts with low distortion. Signal processing uses a 50MHz DSP from Analog Devices with 56-bit filtering. Its processing power guarantees impeccable sound quality adapted to the acoustic characteristics of the room.

The drivers in the SVS 1000 Pro subwoofers were developed almost from scratch for the series. The driver design uses a double ferrite magnet and a parabolic suspension of a long-throw aluminum cone to achieve high sound pressure in the listening room. with a long range for extreme walks with increased indoor pressure.svs sb 1000 pro vs pb 1000 pro

When the enclosed subwoofer is equipped with a powerful amplifier and a quality driver, you can expect deep and clear bass. But only if such a system is properly managed. To meet this challenge, the SVS SB-1000 Pro is equipped with a powerful DSP that can be controlled via iOS or Android apps. It has all the settings you need to get the best bass sound from your subwoofer.

Subwoofer SVS SB-1000 can be called universal simply based on its specification. A 12-inch speaker and 300 watts of power allow it to be used in rooms of different sizes, and if we are talking about a larger cinema, you can simply increase the number of subwoofers - bass depth is enough for a movie. Another obvious and important fact is the size of the model. A cube with a face length of 34 cm is a very compact size for a powerful subwoofer operating from 24 Hz. It is easy to calculate that 34 cm is approximately 13 inches, respectively, a 12-inch caliber speaker occupies almost the entire area of ​​​​the front panel. In addition, it is long-stroke, which allows you to provide a large sound pressure.

An important point: a large working stroke is usually given to small-sized speakers operating in a bass-reflex enclosure. Whereas large radiators (and 12 inches is already a rather large driver) in a closed acoustic design are traditionally made short-throw for better bass control. In this case, the manufacturers clearly had the task of combining high efficiency with small dimensions, so we have an atypical hybrid. In this scenario, the main thing is not to lose the advantages of both approaches.

Minimizing distortion in the SVS SB 1000 Pro transducer is ensured by two powerful high-end ferrite magnets, a magnetic system with a field in the gap, a long voice coil and a rubber surround with a large amplitude of movement. To reduce compression in the magnetic system, a through hole was made to remove air from under the central part of the diffuser.svs sb 1000 pro vs pb 1000 pro

The built-in Sledge STA-325D amplifier operates in class D and delivers 325 watts in operation and over 800 watts at peak. It has a built-in digital processor that matches the speaker to the cabinet and helps achieve a linear output response. The volume, frequency and phase controls look and function in a digital dimension. The SVS SB 1000 Pro has a full set of inputs: stereo low-level, as well as LFE, combined with low-level. There is also a stereo low-level output with a fixed cutoff frequency of 80 Hz. The latter will allow you to "unload" the power amplifier without a processor in the system.

The SVS SB 1000 Pro subwoofer has a switchable auto-standby system and a trigger input for integration into an automation system. Standby power consumption is 0.5 W, so it is not necessary to completely power off the system each time. The heavy and durable subwoofer cabinet looks neat and compact. Thanks to the rounded edges of the body and the rounded grill, it does not attract attention and imperceptibly dissolves into the interior. The only thing that betrays its presence in a darkened room is a bright blue LED shining through the fabric of the grill. The grill is firmly attached to the body.

SVS PB 1000 PRO

The original SVS PB 1000 PRO rocked the subwoofer world with unparalleled performance not only at its price point, but beyond. Now, the SVS PB 1000 Pro subwoofer raises the bar even higher with stronger bass output, deeper bass extension to guttural 17Hz, performance-enhancing dual-port cabinet design, and a major upgrade in user experience. The PB-1000 Pro features an all-new 305mm long-travel cone, dual high-quality ferrite magnets, and an FEA-optimized internal motor architecture for extreme travel and massive, flawless power output.

Thanks to innovations in the cone, suspension, voice coil and magnet system, the unflappable 12" woofer delivers amazing bass never seen before in a bass reflex subwoofer. Using the same amplifier technology as the flagship SVS 16-Ultra series, the PB-1000 Pro features a Sledge STA-325D 325W RMS amplifier, over 820W peak power with a fully discrete MOSFET output. Boasting massive power while providing precision and control, it uses an Analog Devices Audio DSP 50 MHz sound processor with frequency response curves finely tuned for the SVS PB 1000 Pro.

The subwoofer also features the SVS smartphone and tablet app for the most convenient way to adjust volume, access multiple DSP functions, and program custom presets for one-touch tuning profiles optimized for music, movies, games, and more. Adjust crossover frequencies, 3-band parametric EQ, polarity, room gain and more - all from your favorite spot. New to the SVS PB 1000 Pro is a dual port configuration that delivers more output with much less distortion than the original 1000 Series model.

Conclusion

I enjoyed my time listening with the SVS SB-1000 and PB-1000 Pro subwoofers and would easily recommend either model to anyone looking to get good bass on a budget. The harder choice will come down to which one to go with. If you're a movie fan and don't have space constraints, go for the PB-1000 Pro and get that extra bit of extension. If space constraints or SAF is an issue, check out the SB-1000 Pro. The build quality of both is impeccable and getting to control them wirelessly using the best-in-class SVS app is a very impressive extra feature in an affordable, entry-level subwoofer.

On the SVS website, the SB-1000 Pro subwoofer starts at $600 and the PB-1000 Pro starts at $700.
