About the JBL Stadium 1024

Quality and power handling

JBL has been building high-performance loudspeakers for decades, so they know something about bass. They made their latest Stadium Series subwoofers to deliver powerful low-end punch and handle the high wattage of today's car amplifiers.

Handles up to 450 watts RMS

The Stadium Series 1024 10" sub handles up to 450 watts RMS, and it's optimized for use in a very small sealed enclosure. JBL uses the airflow from the internal works to cool the 2-1/2" voice coil, so you can rely on this sub to stay cool in the heat of battle. The sturdy polypropylene cone and nitrile rubber surround will stand up all the abuses of heavy bass output.

Selectable impedance

This Stadium Series subwoofer features SSI™ (Selectable Smart Impedance), a switch which lets you change the sub's impedance from 2 ohms to 4 ohms to optimize its effectiveness. If you upgrade your amplifier or decide to add another sub, you'll be able to adjust the 1024's impedance to work best with your system.

Versatile power

The terminals on this Stadium Series sub will accept up to 10-gauge wire. You'll get full power from your amp even over long wire runs, so you and your subwoofer have the juice you need. See what this JBL sub can do for your system.

Product Research

Features

Selectable Smart Impedance (SSI): A switch on the input terminal allows you to easily change the woofer's impedance between 2Ω and 4Ω settings. (The connected amplifier should be off when changing the impedance.) The power handling is the same for either setting; 450 watts RMS/1350 watts peak.

Terminal: The set screw wire terminals will accept bare wire up to 10 gauge and are tightened/loosened with a 2.5mm Allen wrench (not included).

Enclosure Recommendations:

  • Sealed Box Volume: 0.5 ft³
  • Ported Box Volume: 1.5 ft³ with one 3" diameter x 11.3" long port (tuned to 30 Hz)
  • Free-Air: The woofer can also be mounted in free air to a baffle board (infinite baffle, no enclosure). When mounted in free air, the power handling is reduced by half (to 225 watts RMS).
  • Band-Pass: JBL also recommends a prefabricated band-pass enclosure, but no volume specifications are listed in the manual. Band-pass enclosures often provide the most output available from any amplifier and subwoofer combination, but at the expense of sonic accuracy.

Thiele-Small Parameters: Some of the parameters change based on the impedance setting:

 
Re (Ω) 1.80 4.06
Le (mH) 1.04 0.91
Sd (cm²) 346.36 346.36
Bl (Tm) 10.54 14.98
Vas (liters) 24.22 25.27
Cms (μm/N) 144 150
Mms (g) 188.72 185.47
Fs (Hz) 30.56 30.18
Qms 3.11 2.17
Qes 0.57 0.61
Qts 0.48 0.48
Xmax (mm) 12 12
