About the Product
The Power T2S1-13 subwoofer features 13-inches of effective radiating cone area and a single 1-ohm voice coil for ease of wiring. This subwoofer is not just another made with off-the-shelf parts, we wanted something better, and we knew our fanatics demand this as well.
The KICKER® Solo-Baric® L7S™ is the original square sub. It handles plenty of power with special thermal management systems. You get tons of bass without distortion or compromising on sound quality.

What customers say about "Size & Weight"
Rockford Fosgate T2S1-13 Power 13" T2 Single 1 Ohm Subwoofer
  • The result is a super strong, yet lightweight cone. In the centre of the cone is an aluminum dust cap with the Rockford Fosgate logo dead centre.
  • Really a nice piece of equipment, very heavy, solid speaker.
  • It's is an awesome sub , can compete with the best for it's size but the price needs to be comparable to thier competition.
  • This thing will absolutely destroy any other subwoofer of comparable size.
  • Very heavy and massive subwoofer which will be quite difficult to install alone.
Kicker L7S (44L7S102) Solo-Baric 10 Inch 1200 Watt 2 Ohm DVC Square Subwoofer
  • The sound is great, and the space required is perfect for my car because I have enough space to carry other things.
  • Perfect for my car and takes up little space, which made me very happy.
  • Ideal size for car use. It is very compact and will look beautiful.
  • A heavy sub, so you need to ask for help to install it.
  • The mount does not cope with the weight of the sub, so I just put it in the trunk.

What customers say about "Audio"
Rockford Fosgate T2S1-13 Power 13" T2 Single 1 Ohm Subwoofer
  • If you have never had the opportunity to listen to a system where the capabilities of the product exceed that of the listener, you should. This is just a monster of music.
  • The sound quality is actually better than I expect from a woofer, as it’s so obviously designed to play very loud, for a long time.
  • Even in the big vented box, the bass is pleasant and controlled without excessive boom or overhang.
  • One of the nicest sounding subs I have ever had. I am going to buy another one for my boat.
  • At low volumes, the woofer loses a bit of detail and articulation.
Kicker L7S (44L7S102) Solo-Baric 10 Inch 1200 Watt 2 Ohm DVC Square Subwoofer
  • I love these subwoofers. There are better subs out there but these have great sound.
  • Great hard hitting deep bass! Wired it down to 2 ohms and I'm loving it!
  • This one woofer beats the two that I had hands down. My teeth shake and I get a backbreaking amount of Bass hittin' when she is only halfway pumping!
  • This sub is exceptional for delivering strong mid to low frequency bass. It hits hard and is perfect for me when I listen to Rap, Hip Hop, Dub Step etc.
  • When the sub is playing quietly, you get very strong distortion at low frequencies.

What customers say about "Features"
Rockford Fosgate T2S1-13 Power 13" T2 Single 1 Ohm Subwoofer
  • As you’d expect from such a massive woofer, it’s built on an extremely robust proprietary cast aluminum frame unlike any other.
  • It does share Rockford’s “FlexFit” basket mounting architecture, which allows fine tuning of the subwoofer’s mounting position.
  • Very strong and sturdy construction which has a pleasant appearance.
  • This is the most powerful subwoofer that I have ever had; at its peak it gives out 4000 VAt, which is an excellent indicator.
  • It is assembled well, but when you try to attach it you can damage soft parts.
Kicker L7S (44L7S102) Solo-Baric 10 Inch 1200 Watt 2 Ohm DVC Square Subwoofer
  • Amazing subwoofers a real step up from round by far paired with a cx1200 at 4 ohms thing really shakes up my Silverado.
  • Love this speaker! Has alot of power, clear and at a good price.
  • I like UniPlate Black Plate feature. Plus Perimeter Venting For Excellent Thermal Management is amazing.
  • The construction is sturdy and reliable so I don't think it will fall apart with strong bass.
  • Unfortunately, it does not provide controls. And I would like to customize it for myself.
