Small Frame, Big Bite!
A condensed bass cabinet design with unwavering performance is just what the doctor ordered, and the PJB Compact 4 has the remedy! This cab packs in a quartet of 5-inch speakers boasting supreme Piranha drivers with ferrite magnets and a dual-ported front design for the ultimate combination of tonal range, convictive attack, and authoritative presence. Bassists around Sweetwater love its effortless and characterful 400-watt translation of their bass tones! The Compact 4 doesn’t require a lot of real estate, either, making for simplified stacking, stage and studio space efficiency, and total ease of transport with its integrated heavy-duty carrying handle. Finally, it’s incredibly well protected thanks to an all-Baltic birch framework, ultra-tough internal bracing, and corners of chrome-plated steel. As the saying goes, good things come in small packages — the PJB Compact 4 is proof positive!
High-impact sonic supremacy
The Compact 4’s remarkable sound design ensures stunning performance regardless of the space. Driven by four 5-inch Piranha drivers, its 400-watt response is nothing short of spectacular. Aided by a pair of offset ports aside the grille, this high-caliber quartet boosts your signal to monumental levels, delivering plentiful projection and presence. But power is only half of the equation. Each speaker is awarded clear, spirited tonality by way of a ferrite magnet and also comes engineered within an internal bracing design that drastically reduces signal coloration. Studio-grade translation that’s fit for the big stage? You bet.


Resilient, space-saving build
Given its space-efficient design, it’s remarkable how well the Compact 4 can generate such power and transparency. At barely over a foot wide in every dimension, it easily packs one of the biggest punches you’ll find in a small-frame cab. Valuable studio space, crowded basement corners, and small stages present no snags for the Compact 4. Additionally, when you hit the road, you can rest easy knowing that this cab won’t give in to the rigors of transport and load-outs. Armed with a heavy-duty handle, steadfast Baltic birch framework, and chrome-plated steel corners, the hearty Compact 4 carries easily and handles par-for-the-course bumps and dings like a champ.
