We looked to see if there was any way that we could add to the Briefcase already stellar performance. This is the Briefcase on steroids called the Ultimate!
First we designed a more powerful amplifier from 100 to 200 watts. In order for the two 5 inch speakers to handle this we had to totally redesign a completely new 5 inch driver, no small feat considering that we have already been pushing the envelope in bass transducers. The new speaker not only has a larger and more efficient motor ( it is 2dB louder!), it also has better high and low frequency performance too.
We changed out the vent and replaced it with the RALFR technology we put into the BG75. The result is richer, deeper more tuneful and organic bass.
We kept the battery function here . This amp has all the bells and whistles of the original Briefcase Thanks to the super efficient class D power the battery has the same duration of running time.
The amp will put out 150 watts on its own internal 8 ohm speaker and can provide 200 watts output with an external 8 ohm speaker.
