JBL believes sound quality should never be compromised. And Series III subwoofers make sure you don’t have to compromise flexibility, either. That’s because the high-performance, step-up subwoofers feature SSI™ (Selectable Smart Impedance), an exclusive impedance switch that lets you select the optimum impedance—2 or 4 ohms—for your system. Special aero-cooling design in the voice coil boosts power handling as well as reliability. And an oversized voice coil handles more power than common two-inch voice coils. More power, more reliability, more flexibility—and no compromising. When you’re ready to step up, Series III is your subwoofer.

S3-1224 is rated 4.6 out of 5 by 8.
Rated 5 out of 5 by from Deep bass I like this subwoofer on sealed box. It has a very nice bass. I deal with audio systems since I was little. Jbl subwoofers has a great Hz response which mean more bass. I was originally planing to put 2 but 1 is plenty. This set up works great amazing sound . I couldn't be any happier.

Rated 2 out of 5 by from For JBL... ok... What happened to you guys? This is your selling flag ship now? It's mechanical specs shows sloppy, and a BL factor isn't even present which to me, means a waste of time to even input for theoretical specs... every since you did the GTi series, you went WAY down on quality.... you want someone who knows what's really JBL quality, you email me at the email given below (initials is JBL). Otherwise, flag ship drivers like this are nothing but paper weights.

Hi, I have purchased two of these subwoofers and I would like to know which amplifiers you would best recommend to run them please?

Asked by: Sumentheran
Hi, and thank you for supporting JBL! You have two very powerful subwoofer drivers, and I will always recommend plenty of power, in order to avoid running into problems due to lack of power. Such problems could be lack of control, clipping of the output waveform and consequent damage. Of course, this is only relevant if you really want to push the woofers to the limit from time to time. Our best amplifier for the purpose is the GTR-1001. You should select 4 Ohms on both woofers, connect them in parallel and connect them both to the amp, which will see into a 2 Ohm load, producing about 1.000 Watts. You can of course also purchase two smaller amps, like the GX-A3001, and run them into the woofers that can be set to 2 Ohms, where the amps will produce up to 300 Watts for each woofer. I hope this helps.

Beste, Heb de sub besteld alleen wil een gesloten kist en de sub op ze kop hoeveel liters heb ik nodig?

Asked by: Mike599
Hi Mike, Helaas kunnen wij dit niet voor je beantwoorden. Dit zal je zelf kunnen berekenen, in de handleiding vind je hiervoor de Thiele Small informatie. Deze informatie heb je hiervoor nodig, en elke afwijking in afmetingen van de kist kan het geluid beinvloeden. Door zelf e.e.a. te wijzigen kan je de klank zelf naar je eigen wens aanpassen, dus hiervoor is enige kennis van speakers nodig. Ik wil je aanraden om, als je dit niet eerder zelf hebt geprobeerd, hiervoor advies bij een car-audio specialist in te winnen.

Ik heb deze sub gekocht maar weet niet goed of ik een ported box of een sealed box moet maken. Ik luister meestal naar hardstyle en hardcore.

Asked by: Brendan10091999
Goedemorgen, In principe zijn beide een goede optie voor de S3-1224, en is het heel persoonlijk wat je het beste vindt klinken. Een sealed kast/box geeft een dieper en meer zuivere bass en werkt met een kleinere kast, maar heeft en krachtige versterker nodig om volume te genereren. Een vented kast/box produceert minder precies bassgeluid, heeft meer ruimte nodig, maar is daarentegen luider met een minder krachtige versterker.

I have Alpine MRV-M500 amplifier up to 500 RMS continuous power at 2 ohms and I’m not sure if this subwoofer is compatible? Thank you

Asked by: Allhan
Thank you for your question. The S3-1224 is compatible with your Alpine Amp since the Sub is capable of handling 500W on either 2 or 4 ohms rating.
