SUB 550P



Built-in 300-watt RMS (500-watt peak) amplifier

A 300-watt RMS (500 watts peak power) amplifier lets you play your Studio 550P subwoofer at body-quaking levels without any room-vibrating reverb or excessive heat output. A built-in limiter extends this ability by preventing distortion that can arise out of sudden peaks, taking the audio from merely impressive to completely immersive.


10-inch (250mm) PolyPlas low-frequency transducer

The Studio 550P features a 10-inch (250-millimetre) cone made from lightweight yet rigid PolyPlas cone material. For the listener, this structure means powerful heart-thumping bass with such low distortion that individual sounds remain both accurate and articulate, even at sustained low frequencies. This is the kind of bass that takes surround sound from simply a listening experience to a seemingly tangible, robust environment.


Sealed enclosure

Power and accuracy normally do not go hand in hand. The Studio 550P, however, is by no means a mere normal subwoofer. It features a sealed enclosure that acts to control the woofer cone’s motion, thus providing consistent, reliable sound that remains smooth and rich even at the deepest of frequencies.


Forward-firing transducer

The Studio 550P places you in the centre of the action by sending the action straight at you via a powerful, forward-firing cone. Sound travels directly to your ears without reverberating off the walls or bending around the furniture. This is bass in its most potent form, from a subwoofer versatile enough to be placed in the middle of the room or against a wall.


Adjustable crossover frequency and phase control

A phase switch ensures that the action of the Studio 550 subwoofer’s transducer moves in sync with your main speakers. As a result, the subwoofer’s low frequencies blend seamlessly with the sound coming from the main speakers, regardless of where you place the subwoofer in a room. Furthermore, an adjustable crossover-frequency control lets you optimize the subwoofer for a variety of main/satellite speaker choices.


LFE and line-level inputs

A choice of LFE and line-level inputs lets you either use or bypass the subwoofer’s internal crossover circuits for bass-boosting versatility. This option provides greater flexibility in how you use the Studio 550P while ensuring noise-free connections to virtually any type of audio/video amplifier.


Metal floor spikes included

Unwanted interaction between the subwoofer and the floor can cause distortion – but the Studio 550P includes an array of metal spikes to reduce distortion. The use of such spikes also creates clean sound by placing a cushion of air between the speaker and anything that could potentially disturb its pristine low-frequency waves.

Product Q&A

This is a great sale price for a powered subwoofer. I dj wedding receptions, usually small ones, as a hobby and typically use a huge 18" passive sub. Could this give enough thump as a replacement? I wouldn't need a bass amp anymore too!

My 550P goes into standbye after about 7 minutes of no audio signal. The manual states that it should be after 20 minutes. Can anyone weigh in? Does your sub go into standby under 10 minutes? Preferable those of you who recently purchased the sub.

Looking at the JBL 5.1 wireless system, comes with a 10" Sub. That Sub is Maybe 100W RMS? How does this Sub compares to that one? I assume it is way more power. Is is there a wireless adapter for the 550P so I can use that sub instead?

Asked by: Indiana1965
The Sub 550P is definitely more powerful than the Bar 5.1's subwoofer. Unfortunately The Bar 5.1 can only connect to the subwoofer that it came with and can't be connected to other subwoofers.
