Visaton FRS7-4 2.5" Full-Range Speaker 4 Ohm

Will it require a crossover to pair with Tang Band subwoofer - W2-2040S? My system is a 2.1 channel portable unit.

Asked by: arjunm009
A crossover is not specifically required, but a high pass filter might be needed to get the most output from the system without over driving the full range. For low volumes this won't be a problem.

What is the recommended enclosure volume/dimensions for this driver? Ported?

Asked by: thunk
With an Fs at 250 Hz and a very high Qts an enclosure will not do much for this driver. I would not recommend playing much below 250 Hz through it anyway.

Screw Hole dimensions

What are the screw hole dimensions, diagonally and adjacent?
Asked by: DJK1
These screw holes are 2-1/8" adjacent and 2-15/16" diagonally. These screw holes are oval shaped so there is about 1/8" tolerance when mounting.
