1. What size subwoofer is most appealing to you? 8”, 10”, 12” or ??
I Think two 12" subs are perfect for most home theaters.
2. Do you prefer single our dual driver design, either active of with passive radiators?
Single driver, since you can always just add a second sub and then you can get better sound as well. Radiators don't really make a difference, mostly because I have never looked into the technical or audio differences between the two.
3. Do you like the sound of front firing or floor firing designs?
Front firing.
4. In choosing between SPL or low frequency extension, which is attribute more important to you?
Definitely frequency extension. SPL's can usually be gained by adding more subs or changing positions, but frequency extension is impossible to obtain if it isnt there to begin with.
5. Do you prefer super compact (high pressure) subwoofers or are conventional (larger) designs more desirable?
conventional. I still think the super compact designs are too gimmicky, and i have never been impressed with the sound.
6. Do you place your sub in a corner of the room or somewhere away from the wall?
in a corner
7. Would you rather have a sub with a built in amplifier or a dedicated stand alone amplifier?
For some reason, a stand alone amp would be way cooler, although from a convenience and cost standpoint it is probably not worth it. I would definitely go that route if I had the available resources, though.
8. Would you rather have an Auto Room EQ system with a measuring microphone or manual parametric controls allow you to set the EQ yourself?
manual parametric controls. Who can trust computers?
9. What price range do you feel is the most desirable for a high performance subwoofer system (be realistic! )
$1000-1500 is reasonable. SVS makes good subs in the $750 range, and I consider 2 of those to be a "System"
10. What color and finish is the most desirable to you? If you had the choice of two finishes, what would they be?
Piano gloss black almost always looks good, and then a natural oak, one that could be custom stained, would be preferrable.
