No. Hence why I twice asked; "what am I missing?" Many is the time my thoughts run off in the wrong direction.
(Hey, Bee, we're over here!)
If I'm commenting in general to a conversation, I don't quote anybody and if I'm commenting to someone's comments, I quote their comments so one knows what I'm commenting on and to whom it is I'm responding to. My apologies if my above came across as personal to you or anyone else.
In the end, most conversations of this type are moot. Without room measurements and if subwoofers aren't chosen to compliment a room's structure, one's expectations are likely not going be met, And when one includes a sense of aesthetics with a wife's approval factor, one is surely going be disappointed in the output of their subwoofer system. And then there's always the limitations of one's wallet as most don't have the Benjamins to support the purchase of a proper subwoofer system.
In our case, I've come to the conclusion that to fill our 3,300 cu ft living room, with smooth subwoofer based Home Theater sound which takes into account the typical interconnected adjacent rooms, our subwoofer system would reasonably comprise of two XS30's (stacked) and two ancillary XS15's ($3,872.10) in additional locations to aid in smoothing out the room modes. The above budget does not include a "needed" AVR upgrade to a Denon, 4520CI and "needed" upgrades to existing surrounds to more efficient surrounds. In the grand scheme of things, three little itty-bitty minor details greatly limit the genius of the above idea.
One should note, with the above setup, depth of extension and output is not a problem. Nor is there concern for headroom or harmonic distortion. One can work on the last two impediments on the list (Aesthetics/Benjamins) but for most, the WAF is a powerful force indeed.
Great expectations, major disappointments and when one expects to much from too little, little things break.
(hopefully the above clarifies my position on the original comment you asked about)
