The XSP218 can powerfully reproduce the lowest notes in any music, reliably, consistently and with great fidelity. Modern electronic, jazz, reggae, R&B and rap music emphasize bass and put tremendous demands on low frequency loudspeakers. The XSP218 delivers the deepest, most powerful notes in modern music and is built to take the stress of doing so continuously, to the extremes, without fail.

With 6800W of amplification on board, the MAXX-ill has the dynamic power headroom necessary to reproduce live kick-drums with spectacular effect and adds the extended low frequency response demanded by electronic instruments. Massive power combined with massive power handling means the ability to deliver very high SPL with no concerns about overdriven or blown loudspeakers, which translates into smaller systems doing bigger shows and lower transport, labor and repair bills down the road. And unlike companies selling impractically heavy, complicated and expensive boxes, the MAXX-ill is simple, surprisingly cost effective and efficient, and it can be moved without the need for a forklift!

The XSP218 incorporates innovative new technologies into a rigidly braced, large vented box optimized for maximum output and reliability when used for extremely low frequencies. It is a loudspeaker that sustains its output long-term and is practically impossible to blow thanks to the combination of extremely rugged, very high power handling, long excursion drivers, carefully optimized cabinet and port design and effective but transparent protection systems. The protection systems effectively prevent thermal overload of the voice coils and minimize long-term thermal compression while having virtually no effect on the transient response and peak output of the loudspeaker.

The MAXX-ill provides very high output, low frequency sound with extremely low distortion. The speaker delivers the same frequency response at full power that it measures at low power because it is optimized for full-power operation and is designed to run at full power throughout its operating range. This means the tone doesn't change as the levels increase, the effect of which is low-frequency power and presence that's comparable to double the quantity of competitors' similar boxes.

The XSP218 is extremely flat, delivering response that is +- 1.5dB from 32Hz to 100Hz. No equalization is required to achieve this response. Many competitors claim to deliver similar frequency response capabilities, but if you look closer you’ll see that to achieve this response they very often require equalization. Systems that require equalization to achieve their stated response are still subject to the excursion and thermal limits of their drivers. Boosting low frequency EQ to achieve extended low-frequency response results in excessive distortion or woofer damage at full power unless limiting is applied. Their claimed frequency response cannot be realized at full volume. The limiting necessary to avert failure prevents it, so the character of the loudspeaker changes at high levels. The MAXX-ill does not suffer from these limitations. It faithfully delivers the low bass where most others either roll off or die trying.

The MAXX-ill XSP218 includes dual bridged 3400W amplifier modules for a total of 6800W of power with on-board fixed-latency digital signal processing. The processor is used to provide crossover and limiter functions and the standard settings are
