Look, I'm not Bose fan except for the 901 Series VI and their big pro stuff; but, uh, I sense some fashionable piling on here. Let's get real.
If you are looking for boom or lots of spurious overtones to add definition, then the Bose Acoustimass Sub from an AM 5 Series 1 is not in any way suitable. BUT if you are looking for a sub to fill a medium sized room with a convincingly musical bottom end and you do not play lots of pipe organ music, then it's OK. Also, if you want to rattle your truck's panels and use the sub as a vibrating sex aid for seducing young prospects again, please pass on the Bose. It will not rock THAT boat. BUT if you like to play a little direct-to-disc Harry James and really hear the bite and smooth, relatively accurate, not cartoonish, bass; then the Bose is OK, cubes and all. Further, if you are a dog or parakeet then pass on the cubes. They are built for people's ears, so if you have homo sapiens' ears, then the Bose cubes are OK.
For most interior designers, budget-minded movie fans and frequent party hosts, the Bose Acoustimass system is a big step up from whatever trash their significant other would allow into a public space before Dr. Bose became a marriage councilor with his neat, small, tidy, relatively hifi little box of trash. I am listening to two Series 1 now hooked in parallel to a clean little class D amp from Amazon complete with remote and a rather beefy external transformer. Frankly, this rig sounds better streaming You Tube over "the blue tooth hit or miss system" than 90% of the hundreds of $3000 systems I have heard. And I paid, let's see: $40 for all 6 loudspeakers, $160 for the amp, and, well, I need the phone anyway, but it was a freebee Galaxy 10 with service. So, maybe less than $250 for the whole shebang.
So, uh, give Bose a break. Their steely, harsh, searing, upper-mid-heavy racket makes the Tonight Show Band sound like the cat's meow! I mean, maybe it's not the smile on the Mona Lisa or the Tower of Pisa, but it's OK, just not a trunk thumper. Actually, I would not use a speaker at all for that. In fact, I use 4 $100 Dayton Bone Thumpers to rattle my truck's side panels and bucket seats and provide foreplay for new special friends who are not audiophiles.
Earth One, over!
