EPA subwoofer TUBA

Description

The EPA TUBA is a self powered subwoofer with a 15”woofer / 4″ voice coil. The box is made of 18mm high density birch plywood and the loading is a 3 meters TAPPED HORN with controlled pressure.  

This type of loading allows to have a very low emission on the back, to have a detailed sound and to cover bigger areas than the classic bass reflex subs do.  

The power amp is designed and made in Italy. It features PFC dual-stage power supply with a supplement of power. It also features 2 x boost board, which improves the transient response and sound pressure in general. 

The DSP mounts a high performance processor and converters with samples of 32bit / 768 khz. This amps are CLASS D HI FI GRADE and the boards are gold plated on all layers.
