Subwoofers and Music Listening
Anybody knows what the signal level is for the subwoofer output in A/V Receivers ?
I've been trying to use a standard audio amplifier to power passive subwoofer speakers unsuccessfuly.
I'm not happy with the way home theater active subwoofers treat bass sounds when it comes to listening to music (for movies are fine).
That's why I would prefer to use car subwoofers in my home, with an external amplifier.
Regards,
Daniel.
Home versus Car subwoofers in the same room
My home subwoofer is a DIY 15" Adire Audio Tempest driver in a sealed 0.5 QTC enclosure
For parties I use a "car subwoofer" (DIY 15" Kove Audio M15Z driver in a sealed 0.707 QTC enclosure) located in the corner about eight feet behind my home subwoofer.
I also prefer this sub for rap music because it has less output under 50Hz.
and rap often seems to have too much output under 50Hz. to my ears.
The main difference between these subwoofers other than the location is that my car subwoofer rolls off the bass 12dB/octave under about 50Hz.when used in a large living room rather than in a car ... while my home subwoofer does not (The Adire driver's FS spec is about one octave lower than the Kove driver).
When used in a mid-sized car, my car sub's bass roll off starts about one octave lower than when it is used in my large living room (bass roll off is 12dB/octave below about 25Hz. rather than starting at 50Hz.) due to the cabin gain (bass SPL ramp-up) in the sealed car.
