12" Slipstream™ ported enclosure

Our patented port brings the bass, not the noise.

Series II enclosures deliver the enhanced efficiency and higher output of a vented enclosure, without the distracting noise or “chuffing” generated by a port. The patented Slipstream port dramatically reduces port noise at high sound pressure levels by minimizing airflow turbulence. With high-roll surrounds, proprietary cone design and long-excursion, Series II enclosures deliver deep, powerful bass, with greater accuracy than conventional ported boxes. And the exclusive SSI™ (Smart Selectable Impedance) switch lets you choose 2- or 4-ohm impedance for maximum configuration flexibility. It’s everything you want in a compact, easily installed enclosure.

S2-1224SS is rated 4.7 out of 5 by 9.
Rated 5 out of 5 by from It's very good. My friend (who has 2 15 sundowns, and 4 10s (all homemade)) was even impressed by how loud this thing can get. I'm running it w a $150 hifonics mono amp and it works perfectly. 4gauge installgear wiring was like 30$. It's been a month and had no issues. Vibrates rear view mirror like crazy! Can't rate on durablility yet because I've been running it very conservatively at 4ohms even tho the amp is rated for 1. Don't even need bass boost w this baby!

Rated 5 out of 5 by from OMG- The answer to all your needs. I wasted so much money and time looking for a compact box that would sound just right. whats right you ask? if your like me that goes from Rap (NAS ) to Rock (Strokes) to Movie Score (Mission Impossible) to Electronic (Apashe) you need and want a sub-woofer that hits deep for the rap and just clear thumps of a drum-set. THIS BOX IS IT!. a lot of the boxes i tried where too focused on just deep lows sure for a song like deep cover or get down they sound great hit hard but when you changed over to "Thunderstruck" or "Float on" they would not respond and the music would sound flat. with this box you are covered all around! wish they had a two speaker version with this exact woofer at 4 ohms

Rated 5 out of 5 by from Good sound from premade enclosure I bought this to add on to factory stereo paired with a jbl 600/1 old school amplifier that is built like a tank. Perfect combination. Has a really good kick. Box is light so I not sure about how durable it is but for now it works great. JBL makes great stuff for a reasonable price.

Asked by: Allhan
From what I’ve seen in this thread and what I’ve researched the GX-A3001 is a good amp for this. Idk if that’s JBL but I’ve heard good things about it.

What is the best amp from JBL to pair up with this sub? 

Asked by: Cameronc
The S2-1224SS can handle 275 watts of RMS power handling. This means that any sub amp with an impedance of 2 or 4 ohms and a power output of 275 watts will work fine with these speakers.

Is there a different RMS at 2ohm and 4ohm settings?

Asked by: nbeda
The S2-1224SS can handle 275 watts of RMS power handling. This means that any amp with an impedance of 2 or 4 ohms and a power output of 275 watts per channel will work fine with these speakers. That said, the power that the speaker can handle remains the same whether it's switched to 2 or 4 ohms.

I have two sets GTO609C and a single S2-1224SS (over kill for a 1968 Volvo 122 Amazon). I was considering a GX-A604 to drive the two sets GTO609C and a GX-A3001 to drive the S2-1224SS. Am I in the right direction or is there a better solution?

Asked by: Kevin Campher
Yes you definitely are in the right direction. The amps would work perfectly with your speakers .
