What's in the box:
1 ported enclosure
- Slipstream™ port design
- At high sound pressure levels, air flow turbulence inside a vented enclosure’s port can create noise that sounds like woofer break up. The patented Slipstream port in Series II enclosure uses a double-flared design to minimize turbulence, and eliminate unwanted vortices.
- SSI™ (Selectable Smart Impedance)
- Most car audio system designs call for 2- or 4-ohm impedance. Series II subwoofers feature an exclusive dual impedance switch that lets you choose either load impedance option. Not available from any other manufacturer, SSI lets you reconfigure your system by simply flipping a switch.
- High-roll surround
- Series II enclosure incorporate a high-roll surround that provides superior cone edge suspension while maximizing excursion. It not only increases the cone area, it also provides remarkable linear stability and reliability.
- Proprietary cone design
- JBL subwoofer cones aren’t just built to thump, they’re built to last. Series II enclosure feature an exclusive cone design that delivers superior rigidity for long-lasting performance.
- Long excursion design
- The longer a subwoofer’s excursion is, the more air it moves. And the more air it moves, the more bass you feel. The long-excursion design in Series II enclosure ensures big, deep bass output. Just the way you like it.

Rated 5 out of 5 by 619stig 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 Keith996 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.

Rated 4 out of 5 by Andy Mc from Good Value I like the sub because it reaches deep lows without the voice coil bottoming out. It is also good value for money, with a high power rating. It is a bit large however, and takes up rather a lot of boot space. My minor niggles are a) no metal, open grille, cone protection: b) no handles, c) no pro cable socket, and d) slighly low sensitivity. It is great though! I nearly bought a Focal flax 10" driver for about £149 and a box for £40 but these JBL speakers are properly engineered and conveniently ready for use! The Series 3 digitally powered monitor loudspeakers; with sharp crossover slopes, are also a great buy at about £228 Sterling a pair.

Rated 5 out of 5 by The Dr from Hits hard and smooth! Like the title states, it hits hard, and it hits smooth. Moves my entire car in all the right ways. Definitely a smart purchase, and a great deal for a beautiful box and sub. This sub blows my old one out the door, and I couldn't be happier that i picked one up.

Rated 5 out of 5 by Elabrijn from Wat een geweld! Heb na lang overwegen toch deze subwoofer gekocht met een leuke bijkomstige korting. Kwam netjes thuis via de koerier (prima service van de dpd). Eenmaal aangesloten was ik aangenaam verrast van de kwaliteit en de bass weergave in mijn polo. Geweldig tevreden. Heb dit i.c.m. een A3001 monoblock versterker aangesloten.

Will this sub work with the JBL Club 4505 - 5 channel amp if I connect it together with my JBL component club 6500c door speakers and my JBL rear GX962. Will the same amp power all 5 channels ?
Hi! Yes, the S2-1224SS will work with the Club 4505 since the amp has 5 channels. It can power up your front and rear speakers together with the subwoofer.
