Know before you buy
The sealed, or acoustic suspension, enclosure provides tight, accurate, and highly controlled bass. It is generally preferred for music listening because it offers a more natural, musical response compared to ported designs.
While the d108 is impressively punchy for its size, it is best suited for small to medium-sized rooms. If you are trying to fill a very large open-concept space, you may want to consider a larger driver or a dual-subwoofer setup.
Dynamic Motor Analysis (DMA) is a proprietary JL Audio technology that helps the driver maintain linear motion. This significantly reduces distortion and ensures the bass remains clean and precise, even when you are pushing the volume.
Yes, the d108 features signal-sensing technology. It will automatically wake up when it detects an audio signal and enter a power-saving standby mode when the signal is absent for a period of time.
Yes, the d108 uses standard RCA line-level inputs, making it compatible with most home audio receivers and pre-amplifiers. Ensure your receiver has a dedicated subwoofer output or a full-range line-level output to connect it.
The unit is quite compact, measuring approximately 11.4 by 12 by 13.2 inches. Because it is a sealed design, it is less sensitive to placement near walls than ported subwoofers, giving you more flexibility in your room layout.
