Briefcase Ultimate 200W 2x5 Bass Combo Amp

The Briefcase Ultimate is the massive update to the original Briefcase amplifier from Phil Jones Bass. First the amp was upgraded to a more powerful 200 watts. In order for the two 5 in. speakers to handle this, PBJ had to totally redesign a completely new 5 in. driver, no small feat considering they have already been pushing the envelope in bass transducers.

This updated speaker not only has a larger and more efficient motor (it is 2 dB louder!), it also has better high and low frequency performance. PJB changed out the vent and replaced it with “RALFR” technology. The result is richer, deeper, more tuneful and organic bass. The battery function is still here, and this amp has all the bells and whistles of the original Briefcase. Thanks to the super efficient class D power amplification, the battery has the same duration of running time. This amp will put out 150 watt on its own internal 8 Ohm speakers, and can provide 200 watts output with an external 8 Ohm speaker.
