Tessen - TNS-118A

The Tessen Active models use the same ‘audiophile’ braced plywood cabinets and purpose designed HH drivers as the passive systems, but couple them with dynamic and responsive amplifiers.

500W Class D units drive the woofers, active crossovers and subtle equalisation ensure the cabs, amps and drivers are perfectly suited to each other, and outperform expectations.

As with all HH systems, Tessen Active cabs don’t feature multiple inputs, gains and EQ’s or any of the other functions best performed by a purpose built mixer, just high quality amplification to make your sound louder without colouration.

PA woofers

Many aspects must be considered in PA woofer design: Is it for a sub or a front-of-house cab? If front-of-house, what compression driver will it be used with? What size and type of cabinet must it suit? How many drivers will be in the cab?
