Should i buy a sub that can do the "needit" 150-200 Hz like SVS PB1000 is 19-270 Hz +/- 3 dB, or will it be better to get one that will do something like 19-125 Hz so it will roll off sooner and i will not hear the mid/upper bass ?
Now I think I'm beginning to understand that you are worried that if you cross-over as high as 150 Hz or 200 Hz you will be able to clearly locate
where the subwoofer is, instead of all of the bass coming from wherever in the soundstage its point of origin is supposed to be
, i.e., where it was placed by the filmmakers
It is true this can
be a problem. "Experts" can't seem to agree on exactly what frequency (and below) bass becomes non-directional, it could be as low as 80/90/100 Hz, or as high as 150/200 Hz. A great deal may depend on individual differences, including, but not limited to, how far apart your ears are, compared to the wavelength of the sound being played! Somewhere on AVS there is a thread on this.
I'd be inclined to get the SVS PB1000, set the crossovers to the Gallos where Audyssey recommends, and minimize
the problem by:
- Placing the SVS PB1000 midway between your Right Front and Left Front speakers, right below your center channel. [Edit: written before I saw your response above. If the SVS MUST be off center, can you disguise it (see below)?]
- If there is a way to disguise the subwoofer with some acoustically transparent cloth (a grille cloth, if the SVS comes with it) so that listeners can't see it, or it is less obvious, that might help. Out of sight, out of mind.
- I think the SVS PB1000 has a port on the front of the box. If this is true, aim it straight forward, and place its rear side against (or almost against) the wall. [Or if it must be off center, could you try it in a front corner?]
- Make sure there is nothing that vibrates near the subwoofer that could give away its location.
- If and when you eventually replace the Gallo main speakers, get some that go down to about 40 Hz, and try crossing them over at about 80 Hz.
With all of the above, experiment, experiment, experiment.
With music that is mostly midrange and treble, like solo violin or viola, speakers like your Gallos might be fine. I was fooled by some about their size, that were hidden in a store -- with no subwoofer -- playing ethereal Hildegard von Bingen music with great clarity (I bought the CD, "Voice of the Blood."). But full orchestra, pipe organ, drums, bass guitar or modern movies
are maximally demanding.
