The BasX S8 subwoofer is the smallest BasX subwoofer, and is ideal if you need deep, clean, musical bass, and space is at a premium. The BasX uses a heavy-duty long-throw 8” driver and an efficient 150 watt Class D amplifier to deliver bass response down to 28 Hz.

BasX Subwoofers: Performance, Power, and Simplicity

Our Emotiva BasX™ Subwoofers were designed to reproduce the lowest frequencies in the audio spectrum accurately and with exceptionally low distortion – even at high listening levels. This means that our BasX Subwoofers can deliver the dynamics and raw power you need to make a modern movie soundtrack sound truly monumental, but still offer the precision and musicality you need to get the most from well recorded music. With our BasX Subwoofers, you don’t have to compromise; you really can have it all.

Our BasX Subwoofers come in three models: the S8, the S10, and the S12. Each model includes a heavy duty high excursion bass driver, powered by a high-efficiency Class D amplifier, and offers controls that allow you to configure it to work perfectly in conjunction with your main speakers. The various models offer identical controls and similar features; the main difference is that the larger models can produce higher output levels, and their frequency response extends even deeper.

The cabinets, which are quite compact for the performance they deliver, are built of heavy, acoustically inert HDF, and are covered in attractive yet durable textured vinyl. Sculpted removable grill cloths perfectly match the outline of the cabinets, and heavy duty integral feet provide support and minimize vibration. All controls and connections are conveniently located on the rear panel, which also provides cooling for the internal amplifiers.

The goal of putting together an exceptional audio system is to enrich your life with outstanding sound. It’s all about the music and the cinematic experience.
