Sony XS-GTR121L

Overview

Our take on the Sony XS-GTR121L

The design of the Sony's GTR Series XS-GTR121L 12" 4-ohm subwoofer not only catches your eye, but it also helps give you better bass. The five-sided woofer cone reduces standing waves, which can diminish the bass output. The unique "dimple" design makes the cone more rigid so it'll hold its shape at high output levels, and it reduces the cone's weight so it's more responsive. You'll enjoy tight, accurate bass.

Five sides equals big bass

The design of the Sony's GTR Series XS-GTR121L 12" 4-ohm subwoofer not only catches your eye, but it also helps give you better bass.

This XS-GTR121L handles up to 400 watts RMS, impressive for a sub in this price range. Even though the cone has five sides, this Sony still fits in a standard round opening in either a ported or sealed enclosure.

To drive this single subwoofer, we recommend a mono amplifier rated between 300 and 600 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Do not sleep on these if you aren't trying to go win a competition. If you're a bass head and not looking to spend a ton of money, get em. If you were considering buying them, do it right now. They can handle a good amount of power. I'm pushing 3000 watts and 480 rms x 2 and they sound fantastic. I have a buddy with jbl audio two twelves using 3400 watts and he's put a lot more money and time into his and mine sound the same if not better

Pros: Quality sound and a good price

Cons: Not one I could point out

Features

P5 Cone Design: The five-sided polypropylene cone uses a unique dimpled design; this stiffens the cone, resulting in lower distortion.

Surround: To improve cone motion control, the surround is made of ThermoPlastic Olefin (TPO), a combination of rubber, polypropylene, polyethylene, and a reinforcing filler.

Binding Posts: The binding post wire terminals will accept pin connectors, spade lugs, single banana plugs, and bare wire up to 8 gauge. The binding posts are spaced too far apart to accept dual banana plugs.

Enclosure Compatibility: This woofer can provide extended bass in sealed and ported enclosures:

  • Recommended Sealed Enclosure Volume: 0.84 ft³
  • Recommended Ported Enclosure Volume: 1.37 ft³ using one 4" diameter x 9-1/8" long port

Why did you buy this?

Because i received one as a gift and your web site says to use subs of the same watts and ohms, now just have to match the the two subs with the right amp already ordered the box from you which fits great [ Tommy  Jun 29, 2016 ]
