Home Speaker Asylum

General speaker questions for audio and home theater.

RE: I concur (55Hz?)

80 is too high. It's a thumb rule for hometheatre and nothing more. How low can your speakers go? Surely lower than 80.

Every subwoofer integration I do here uses 24db/octave lowpass for the sub and a crossover frequency from 50-65hz depending on which speakers I am using the sub with. The 65 hertz situation is with a sealed box design with 7" midbass drivers. The 50Hz situation is with a ported design using nominal sized 8" "midwoofs".

Unless you're running 5" high-Fs drivers in a sealed box there would be no need to cross over so high.

The NHT may also have 2nd order (12db/octave) slopes, making it very hard to elminate localization if crossed over above 55 or 60Hz.

80Hz with a 2nd order is almost always locatable IME. 80hz with 4th order is bad enough... I like 4th order, 65 MAX.

I don't own a speaker that requires a higher crossover point and except for home theatre I don't recommend that one does! ;)

Cheers,
Presto
