It takes power to produce the high volume that audio lovers adore. Fortunately, the JBL SP150 250-millimeter (10-inch) powered subwoofer has that power: 150 watts. So blast the bass as loud as you want. The SP150 can handle it.

Some subwoofers push sound waves at a wall, but the JBL® SP150 250-millimeter (10-inch) powered subwoofer has a down-firing driver that sends sound to the floor for a cleaner response with fewer unwanted sonic reflections. Low-frequency sound won’t bounce from surface to surface but will radiate up from under you for bass that you have to hear (and feel) to believe.

Today’s speaker systems need to carry a wide variety of signals from a wide variety of components and sound sources. That’s no problem for the SP150 powered subwoofer. Its LFE (low-frequency effects) and line-level inputs ensure that every note will reach your ears.

Raise the volume level. Switch the phase setting. Change the frequency where the subwoofer interacts with other speakers. The SP150 has controls that let you make the subwoofer sound exactly the way you like it.

The SP150 powered subwoofer comes in a wood-grain vinyl cabinet that looks good with the other speakers in the Loft Series. And its compact size – 16 inches (406 millimeters) tall, 12-1/2 inches (318 millimeters) wide and 14 inches (356 millimeters) deep – allows it to fit into almost any room.

SP150 is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Excellent Sub Woofer Had my eyes on this sub for a while now. Caught it on sale and got it for $119.00 at my local electronics super store. I paired it with my ES80s and wow, talking about shaking the house. I honestly don`t think I could have done better. Bass is solid and tight. I have a 5:2 Denon setup and can`t wait to get the 2nd sub, not that I really need it now :)

Can I connect the JBL SP150 to my computer without using the receiver?

Asked by: makedoniya
Thank you for the inquiry. Yes. This product is powered and has a subwoofer rca line input connection. If the computer supports this connection it will work. An adapter may be required. Best Regards.

is there a "3.5 mm Aux In " port ? If not , how do I hook this up with a portable player device ?

Asked by: PGNIP
The SP150 is a powered subwoofer, and must be connected to the subwoofer line output of a receiver/amplifier using RCA cable and plugged into the wall outlet in order to function.
