Active bass-reflex subwoofer with 200 mm woofer driver 

This, the smallest but still powerful Betasub model, is powered by a 140 watt high-performance power amplifier and covers a low-bass bandwidth that ranges from 200 to 25 Hz – which is infinitely adjustable between 200 and 50 Hz.
 
 
 
The downfire case design enables the subwoofer to deliver a bass that in relation to its external dimensions is very deep and powerful. The reason: the cone surface area has been fitted at a very small and precisely defined distance from the floor in the solid and low-resonance case. The driver is supported by the Airflex bass-reflex port that has been secured to the front of this bass powerhouse with five screws. The Betasub 20A is the ideal bass partner for a loudspeaker from Magnat´s Vector 200 series.
 
 

Downfire design for crisp, deep bass

The downfire enclosure design helps the Beta Sub 20 A to produce a very deep and strong bass foundation. The driver is supported by an Airflex bass reflex port at the front. The bass reflex output, secured by five screws, ensures untroubled and interference-free enjoyment, even in critical sequences.

The terminal

This subwoofer is driven by a 140 watt high-performance power amp – serving a deep bass range of 200 to 25 Hz – and is infinitely adjustable between 200 and 50 Hz.

Defined clearance below

With a very small and precisely defined clearance between the bottom of the unit and the underlying surface, the subwoofer membrane surface can be particularly well controlled and pushed to the limit acoustically.
