We were among the very first dealers to bring Phil Jones amps to the US market, and we've brought them back on board!

I'll be updating the specs on this amp with my personal descriptions very soon. In the meantime, here's the information as provided by PJB.

PJB’s huge emphasis on research and development ensures that no other cabinets sound like a PJB cabinet.
Phil Jones Bass cabinets are precisely tuned using multiple loudspeaker analysis programs to reduce cone movement at the lowest frequencies, and to increase low frequency output. PJB employs a full size anechoic chamber for acoustic measurements and a laser scanning Doppler interferometer to analyze cone movement in 3D across the whole audio spectrum.

A protective slip cover is included with all PJB speaker cabinets.


Today’s bass players demand more portable rigs without any compromise in performance. The Compact 4
has a small foot print while providing the ultimate in high end audio performance. It is constructed from the
finest materials including Baltic Birch plywood and a rigid internal bracing design that keeps cabinet color -
ation to its lowest. The four 5 inch “Piranha” drivers feature a ferrite magnet structure for superior dynam-
ics, extended bass response, and punch/attack.

The Compact 4 reproduces effortlessly the true tone of any bass or player with unparalleled sound that will
become more prominent and inspiring to you, your band, and your audience. Physically, the Compact 4 has
unmatched flexibility and portability and is capable of being used alone or in stacked multiples.
