Let's get this clear right from the start. Yes, these sound MUCH better than the Bose Acoustimass speakers. They have more range, are louder, clearer, and are MUCH cheaper. However, never forget that these are SMALL speakers. While they sound excellent for the size, they are never going to be able to replicate the depth of sound of a good bookshelf and especially a full-tower speaker. That said, this is a stellar choice for someone wanting a mid-to-higher end surround sound system that is small and packs a punch. That's not to say it's now without it's flaws. Now on to the review:
-Excellent speaker design- just picking it up you can tell the build quality is there (they are pretty heavy for their diminutive size!). Definitive is known for the great build quality on the towers, and these speakers are no exception.
-Very good sound quality from the speakers- though a bit on the bright side. This is not a flaw in the speaker so much as a limitation from the size. Again, that mid-range punch is lacking- however, unless you're listening primarily to music (and if you are, then you shouldn't be buying small speakers!), you won't notice. They sound great and can easily fill a large room in a movie setting, provided you have a great receiver.
-The set has a TRUE (albeit small) center channel. Most of the other brands tend to through in 5 piece matching speaker design (like Bose, for example) - however, Def Tech has been thoughtful and provided a traditional center channel. This makes a very big difference in sound quality- the main speaker in a surround sound system during a movie is the center channel.
-Being that they are small, they can literally disappear in a room, especially when mounted on the walls. They also come in a white finish as well to hide better with white walls.
-EASY and CHEAP way to build a 7.1 setup. Add two towers or bookshelf speakers and you have a cheap and great 7.1 surround sound system.
Cons: I'm going to digress and point out that there is a difference between true cons and nit-picks. I'll point this out as I go:
-The included subwoofer is sub-par. While it's not bad for a movie experience, it just doesn't have the same punch and depth as a traditional Def Tech (or other brand) stand alone subwoofer. However, realize that this entire speaker package is $799- a great subwoofer can be $500 alone. My advice is to try it out and if you don't like the sound, add a better one! There's no "surround sound package" that's going to be perfect.
-These speakers do not like to be "over-driven." What I mean is that if you have either a) a receiver that's too powerful or b) a receiver that's underpowered- and you like to crank the volume up...then expect to have blown speakers in the not-too-far future. A great amp is the key to these things sounding as good as they do and have a long life. Don't expect 100% reliability if you abuse them (which is true about most speakers). That said, Def Tech has a 5-year-warranty (and BBY's Geek Squad makes it 9 years!!) so if you blow a speaker it's not the end of the world.
Nitpicks and random thoughts.
-Those of you complaining about not having speaker wire or a subwoofer cable included clearly have never had a home-theater-in-box from another manufacturer. I'm actually GLAD they don't provide the cables because usually included cables are beyond terrible. They're absolutely atrocious. Seriously, why spend so much money on a good speaker package, a good receiver, and then skimp on something as important as wiring? Good speaker wiring (and subwoofer) cable is relatively inexpensive and makes a DRAMATIC difference in sound quality. Don't be cheap!
--The speaker mounts are not included in the box. If you plan on wall-mounting the speakers, then you have to purchase Def Tech specific wall-mounts. These aren't exorbitantly expensive like the Bose mounts so it's not bad, but it's annoying that universal mounts don't work. That said, the mounts allow the speakers to pivot and are great quality!
All-in-all an excellent speaker package- especially when you factor in the low cost. Yes, you can buy a Polk Audio or Klipsch speaker package for cheaper, but I guarantee you will not come close to the sound quality, build quality, or longevity of these.
