After perusing various forums and reading dozens of reviews on budget speakers, I recently purchased a set of Acculine's for a 5.1 setup. Specifically, I bought 2 A3 towers, an A2 for the center, and 2 additional A2s for the surround channels (by the time I was ready to purchase, the A1 was out of stock). Naturally, I completed the set with an Asub. I am driving all of this with a Pioneer VSX-1018AH-K receiver. I set the receiver to the 6 ohm setting, and have not been having any problems thus far driving these speakers.
So far, I can say that I'm impressed. I'm not an audiophile, but I do appreciate good, clear, dynamic sound. And, to be sure, I'm certain that I could do a ton of additional tweaking with the reciever as all I have really done is run the MCACC setup. The tweeter is really good: when listening to music, I've been able to hear certain nuances that I wasn't able to pick up with other speakers. In stereo mode, the A3s provide for a nice, musical experience with enough bass to get the job done. I've done more music listening than movie watching so far, but I have noted that the sub provides very nice bass for movies in my relatively small TV room. In fact, it can shake the room if I turn things up. The A2 has worked very well for my center and surround channels. I am looking foward to putting the system a bit more "through its paces" in the near future.
All told, I spent less than $1000 (including shipping) for what seems to be a pretty decent 5.1 speaker system. I am almost certain that this system sounds better than anything at a comparable price point from a "big box" retailer such as Best Buy. It is, by far, the best speaker system I have owned to date (again, note that I am not an audiophile -- I just like good sound value for the money).
The fit and finish of the speakers was fine and the boxes were well assembled. No, they are not "fancy looking" but they blend in just fine with my setup and I'd rather purchase a speaker where most of the cost was in the components rather than a furniture grade wood. That's my way of saying exotic looks aren't that important to me. My wife did comment, when I first put up the A3 towers, that they looked sleek and sexy (if you saw the old Marantz speakers they were replacing, you'd understand where she was coming from).
My experience with the AudioInsider was pretty good. Jon Lane was always prompt in answering the phone and responding to emails. He is very knowledgable about his products. They did switch shipping companies right as I ordered, which delayed things a bit and prevented me from getting a tracking number (I suspect their system for this had to be re-tooled for the new shipper). All told, I had my speakers 8 days after I placed my order -- in my opinion, that's an acceptable order-to-delivery time. If I ever consider getting additional speakers (for 7.1 someday, perhaps) I will stongly consider purchasing them from the AudioInsider.
On a side note, I looked at their site today and noticed the Acculine's were no longer displayed -- perhaps they have sold out of that line temporarily? I do know that Jon was expecting them to run out sometime in February or March. It'll be interesting to see what the new Acculine series turns out to be.
