B1800XP : Very good subwoofer

The subwoofer sounds very powerful as you can expect from 18" sub. Sounds very deep and accurate for the 18" sub. It is intended for live situation but I use it as my control room/monitor subwoofer and it works in that regards very well. I give for "features" 4 points because the subwoofer doesn´t have very flexible EQ onboard. But in case you have possibility to EQ/make room correction in your DAC or DAC software it is not problem at all. I use the sub with settings crossover at 70 Hz, without 40 Hz boost on subwoofer onboard EQ. It looks like with the crossover frequency 70 Hz it is perfect. If any corrections are needed then only ultra low below 40 Hz but I don´t miss that low part so most of times I use the sub B1800XP without any EQ correction. In conclusion the B1800XP is very powerful and fine sounding subwoofer. It can be use not only in live situations but as control room/home hi-fi subwoofer. The amp of the sub sounds very pure and much better than many many quality brand hi-fi subs (e.g. compared to some older Dali 12" sub the B1800XP sounds much much better.
