Question: HI, does all the speakers need to be connected to the subwoofer or directly to receiver?
Document: This is my 2nd Bose, but the first home theater system, I had Bose companion 2 multimedia speaker, I connected this to ONKYO TX-SR508, sound quality is great.I had a issue with sound quality initially, but changed the placing of the subwoofer little bit and adjusted the speaker position, the sound quality is simply Amazing and Awesome!! !....
Second, you need a high quality amplifier. I am running my Acoustimass 6 set from a high-end Yamaha receiver, and I optimized the speakers with a mic that plugs into the amp and then automatically self-tunes everything to the room setup. In summary, these speakers are unbelievable for their size. I would even be happy if they were huge and made the sound they do. Those who are leaving bad reviews on these speakers and saying bad things about Bose are unjustified in their claims.
I got this system with an onkyo TX-SR307 5.1 receiver. These speakers are ok, but you could easily get better ones for around $300 from klipsch. I got these, because they are small, and for bragging rights. I have them paired with a kicker solobaric l5 12 inch and a dayton 500 Watt RMS subwoofer amplifier. They are very clear, and give me some good frequency response.
I manually changed it to +3. Now, it is a lot better for music. It does sound like what I heard in Bose showroom. The movie sound effect is still cool. I think, the reason that make Onkyo receiver set the volume level very low for Bose speakers, because Bose bass module is not exactly a subwoofer. It also produces some midrange sound, which could mess up Onkyo automatic speakers calibration. One more good thing that I like about the AM6 is, speaker cables are included.
People at the store told me that I may have to wait for 45 days. I think, that's OK. But, I can't live without some nice music for 45 days. Then, I placed my order for the AM6 and also brought home a pair of an inexpensive Bose 161. The 161 alone sounds very OK for music. Anyway, my receiver is Onkyo TX-SR605S. And my audio sort is the Mac mini optically connected to the Onkyo receiver. I could make my neighbors dance with this set.
One big cord runs to the amp outputs from the bass module, and simple plugs run from the bass module to your speakers.One caution- you'll need Bose wall brackets to hang these from your walls since the back of the satellites are threaded for a screw. I used to hang my previous speakers from heavy-duty picture hangers!
If they were sold at a lower price point, I think almost everyone would have them, at least in one room of their home. Like most people, I feel that price is their biggest downfall. But I don't hear BIG sound coming from anyone else's tiny speakers, so they kind of have the market cornered,if you need loud,full,and clean without taking up hardly any space.
NOTE: a large amount of reviews fall under the "Bose Bashing" category. While I don't particularly like Bose products, this review was written from an objective viewpoint based off experience with this product.These speakers are great for watching movies- especially "special effects" heavy movies, where surround sound is particularly important (such as "transformers"). The subwoofer is amazing.
So, the pair 161 are now the back surround speakers. With the AM6, I got a 7.1 system. The first Onkyo automatic setup was great for the movies the floor and the walls were shaking. for some reasons, the floor and the walls were still shaking for music too. That is a little too much for me. The bass wasn't like a strong punch. It was more like a really annoying subwoofer effect from the next room. I was a bit disappointed.
I've always wanted to have a Bose Acoustimass system in my home and finally was able to afford one.Although a bit pricey, it IS WORTH IT!! I've always been into home theater setup since I was 14 years old and have tried every which combination, product and vendor.This thing has BIG SOUND from such tiny satellite speakers, or maybe it's the subwoofer that adds depth.
Answer: Yes, actually to the subwoofer.  The sub is serving as the middle man persay. One set of wires connect from the sub to the reciever.  Then a set of wires connect from the sub to the speakers.
