Yeah, weight belts and proper lifting are required for this one.
Mike, considering your various sub options, the low end specs are all very similar (-3 db point is 20Hz for Force and Titan and 19 Hz for Maestro). Obviously in SPL, Force < Titan < Maestro. So, it seems that the deciding factor between these options should be SPL required, or with SPL needs held constant, room size should drive a choice ($$$ be damned of course).
Clearly you can't assess the SPL needs of others. But, applying your ...
Jack:
It is a great question, and one that we deal with daily. I wish it were as simple as a matter of room volume, but that is only one factor. It seems that most people don't really listen in "sealed" rooms. Many of today's homes have open floor plans with rooms open to other rooms. There are two other factors which come into play: individual preferences/needs, and other equipment used. What I do is ask the following questions:
What approx size is your room, what is it like in terms of furnishings, is it open to other rooms etc.
Describe your listening habbits, what you listen to/watch, how loud
Describe the rest of your system, processor/rec/preamp/amps/CD-DVD screen etc.
Sometimes I'll need to ask for clarification, and we email back and forth a couple of times, but with these questions I can usually get a pretty good idea of what sub(s) a customer needs.
Many of our customers just know what sub(s) they want and place the order. But quite a few need some additional assistance or a confirmation that what they're planning will work out. Because this is a pretty time consuming process, I've thought of trying to streamline it with a set form they could answer that would pretty much automate the process. Just haven't had time to get around to it. And, fact is, I think direct, personal contact with customers is important.
Thanks for asking the question, have a great day!
