The new & improved Symphony amplifiers are packed with even more power density than the highly renowned originals! Introducing the version 2, bass-only optimized model of the S1, dubbed the S1v2. The S1v2 does even more power than the S1, in a slightly larger frame. It is designed to be an absolute top choice for a subwoofer monoblock amp at this power level. Where as the S1 is a full range model, suitable for subwoofer duty or midrange/midbass, the S1v2 is designed and developed to be as efficient and stable as possible for subwoofer-only duty. The S1v2 is rated for 1650w @ 1ohm Efficient design only requires the use of 4 gauge power and ground cables. New Custom tooled Symphony heatsink optimized for uncompromising heat dissipation while keeping form factor at an all time low. Built in 18db/Slope crossover network allows for precise adjustment of your system's needs. All Symphony models utilize heavy copper traces in the Korean built boards, as well as top quality components used throughout. Input signal transfers cleanly to the board via the Tiffany style RCA input jacks. The S1v2 comes with a remote bass knob if you're into that kind of thing. The S1v2 sports a silent ball bearing fan to keep it happy no matter what you throw at it. S1v2 Rated Power output @ 13.8v (RMS):

  • 1ohm: 1650w
  • 2ohm: 1000w
  • 4ohm: 600w

Good quality
Good quality. Worked great for the wedding my son was in. He was wearing size 12 pants at the time. Jacket fit perfectly. The pants were too long but easily taken up.

No refund sent after weeks
Size: 7, Color: Navy Blue
Product was great but too big for my grandbaby. After sending it back to get a refund to purchase a new one they didn't send a refund back and I'm constantly getting different days that a refund will be recieved. Will not purchase from this vendor again.

Good quality for the money
Size: 10, Color: White
Really happy with the fit! The pants are a little big, but it’s nothing a belt can’t fix. The sleeves are on the short side, but my son is very tall so that could be the issue. My main complaint is the buttons get caught on threads when you’re buttoning and unbuttoning. So the quality isn’t perfect, but for the money it’s not too bad. Besides that, it’s very sleek white, slim fit, and looks great.
