Audio Pro Sub B1.39 User manual

Sub B1.39
The B1.39 is the latest evolution of the famous Audio Pro
subwoofers with a newly developed 10 long throw woofer
equipped with double short circuiting rings and a new
400W amplifier. It really shakes foundations! The latest
sound standards set by Home Theater put a lot of focus
on subwoofer performance. Film producers add a huge
amount of low frequencies (bass) in order to strengthen
and fortify effects and modes in the film.
A subwoofer is always superior to any big full-range
loudspeaker in the sense of performing bass. The B1.39
ensures not only extremely good low frequency response
but also very low distortion. True low frequency response
has so far been quite expensive  until now with B1.39.
