TAPCO J2500 – Big power amp-2x750W-4 Ohms

When it comes to power amps, it?s all about power, reliability and price.
Thankfully, TAPCO?s J?1400?delivers on all fronts. In developing these amps, we devised a rigorous power amp test which was literally un-passable by dozens of name-brand amps on the market today. Our new Juice Series passed the test with flying colors. It?s pure premium. Midrange and highs are clean and dynamic. Bass is tight, clean and has the authority one would expect from larger, more expensive power amps.
