Phil Jones Bass Briefcase Ultimate

This is the Briefcase on Stdroids call the Ultimate! Phill Jones designed a more powful amplifier from 100 to 200 watts. In order for the two 5´´ speakers to handle this the company had to totally redesign a completely new 5´´ driver, no small feat considering that the amp have already been pushing the envelope in bass transducers. The new speaker not only has a larger and more efficient motor (it is 2 dB louder!), it also has better high and low frequency performance. Phil Jones changed out the vent and replaced it with “RALFR” technology they put into the Double 4 BG-75. The result is richer, deeper, more tuneful and organic bass. The company kept the battery function here, this amp has all the bells and whitles 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.
