In this forum there have been countless requests that Sonos produce a less expensive/smaller sub. While the request for a less expensive model may have its merits; IMO smaller size does not.
Sonos did an excellent job in designing the current sub that IMO should check all the boxes for the audience in this forum and those outside of it looking for good low-end with music (without sounding muddy or booming) and enhanced LFE for movies_that don’t overpower. If one thinks about it designing a proper sub is probably more involved than designing a speaker.
Speakers are generally front firing with no need to consider phase control as with a sub. Speakers are meant to be heard; and it’s not a sin for your ears to determine from where the sound is originating.
Subs on the other hand are intended to disappear. If you can pinpoint where the low-end is coming from then that sub is poorly designed and quite frankly a piece of junk. Granted if you are standing on top of a sub (not literally) you may feel more of the vibrations but the acoustics should still be somewhat masked directionally. BTW, I make no apologies for my previous statement about “junk”.
Referencing a smaller size. A subs dimensions and overall design are not taken lightly. The Sonos sub with its seamless cabinet and dual facing cancelling drivers are IMO an engineering delight. Compact but still able to pull every bit of intended low-end from a recording or LFE from a movie.
Are there better offerings…well sure there are. But not at the price point of the Sonos sub that delivers clean bass without a bunch of electronic trickery. My point being is that if you want a smaller size sub don’t expect the same performance as is offered by the current model. There are limitations to everything. *
One last comment. I’ve also read it mentioned that the Sonos sub is “overkill for my space”. Any sub if not properly tuned can be considered overkill. That is one reason why TruePlay is an important option if one has an iOS device (or can borrow one).
Lets’ rattle the shingles off the roof…but ever so gently :8
* Not saying that it’s impossible to accomplish; but I doubt seriously it could be done at a price point less than the current model. Smaller products that deliver the same as their larger counterparts always cost the same or more. Ever price a counter-depth (compact) version of a refrigerator versus the full size version? You might be unpleasantly surprised.
