Okay how's it hanging fellas? I got an OLED tv a few months ago and am currently in upgrade frenzy. I want to make my HT room have audio coming from every damn which way. This post is going to be a novel of sorts, only without an engaging plot or climax to look forward to, so if you stick with me I'll give you a sticker. I've got stars of various colors and smiley faces, your choice.
So, my current setup is 7.1, powered by a Yamaha rx-a3000 receiver. I love my receiver, and it is upgradeable to 11.2 channels through external amperage. Complications with that represent the bulk of my questions, but I'm going to hold off on it until last.
The room is approximately 18 feet long and 8 feet across. This is a guess, but it's a rectangle exclusively for my HT. I've uploaded a picture of it below so take a look. The tv, center and front channels are at the far end on the narrow wall, projecting down the rectangle. The seating area is a couch which is halfway down the room. Behind it is a table and some other things. This room of my appartment is my man cave and when my girlfriend moves in shell not get her mitts anywhere near it, but she'll be nagging me about large upgrades so I must get my fill now
Now, I listen to music a lot and I do so from different areas of the room. My turntable is also behind the couch, with its own preamp wired to the receiver. I also have company over quite frequently, so one distinct sweet spot was not my goal, as it remains. Because of the relatively small room size and my need for quality audio throughout, I opted for omnidirectional sppeakers.A decision I never regret, though unnecessary for the front channels which a look at the picture will show.
So I've got 6 mirage nanosats, mirage's s8 subwoofer yet my center channel has changed to the definitive procenter 1000 as I needed dialogue to compete, and that CC was excellent. Despite the seemingly disproportionate power of the receiver vs. the Nanosats, the room sounds very, very good. Excellent, in fact. Those things pack a tremendous punch when many are utilized, and the soundfield is truly massive. They even handle death metal with relative aplomb.
Now, here are my upgrade needs/desires, then for the advice.
1) New front left and right channels of the "large" type; that is ones which have good enough internal woofers to handle all frequencies and be set as such by my receiver. I no longer want the front sound stage to be omnidirectional, but just to blast awesomeness straight down the length of the room.
2) Add a subwoofer on the other side of the room to balance out the bass and create .2. Currently the single sub is under the couch on the left. I believe with two subs they should match, and Mirage products have all been discontinued so I'll need to buy 2 new ones and ditch the mirage. It more or less made loud booms over actually outputting clear notes, and clarity is a must over actual boominess. I want these to be capable of wireless, as it would otherwise require RCA cables running along the floor.
3) Buy 2 more omnidirectional speakers for the regular surrounds, channels 4 and 5. The only ones I can find which are marginally more powerful than the nanosats are "JAMO 360 s35". These particular ones need not be drastically more powerful, as the nanosat sounds good as it is, and there are going to be a trillion speakers now. Just a small boost in power plus these offer even a slightly wider soundfield than the nanosats which I think will fill the rear nicely. The 6th and 7th channels I'll leave alone.
4) Now I will have 4 leftover nanosats. I will use these to fulfil the "front presence" and "rear presence" channels, thereby bringing the grand total to 11.2 channels. While the receiver is native 7.2, it has RCA outputs for 11 channels, all labelled, allowing for external amps to power whichever speakers you'd like.
Okay, that's my guideline. If you made it this far, maybe you're willing to go a little further. It would surely be appreciated. I've got those stickers waiting. So here are my advise inquiries, with the final question being the most important as it is presenting an actual roadblock no matter what speakers I choose.
1) Recommendations for either bookshelf or tower speakers that I could set to "large" via the receiver, and will not break the bank in order to fulfil the front channels. I will not be changing out my center channel. I'd like all my new gear to be high quality and better than what I've got, but in this room I do not need to spend multiple hundreds per speaker. I'm looking for "bang for your buck" type gear which will still impress.
2) WHAT SUBS? With so many options I'm not sure where to look, and as I need to purchase 2 they may run up a fair penny. But this, I think, will improve my audio the most and balance out the room. What wattage do you beleive will suffice for these subs? And again, I'm looking more for crystal clear bass reproduction than sounds which will simply rumble the walls. And do wireless connections for subwoofers even perform as well as if they were wired? Because wiring them will be unsightly, but I'm tired of having more bass on the left side of the room. That's gotta stop and I see no other way than to make one wireless though I'm nervous itbwont perform well.
3) I think I'm pretty set on the large Jamo 360's (there are two sizes) to replace the main surrounds. Omnidirectionals sound awesome for rear speakers and I'd like to keep that type of sound, but I cannot find any real reviews of them yet so input on those, anecdotal or otherwise, or other omnidirectional options would be appreciated as I don't see any other options whatsoever. Maybe I've overlooked a better one?
4) Placement of the four now freed up nanosats, which will be used as "front presence" and "rear presence", two each. Where does one place those channels? It's my understanding that they are mainly for mild ambient noise and soundfield depth. I was thinking of hanging them upside down directly from the ceiling due to their 360° nature; is this a good option for those channels? I've never heard presence speakers in action before, so I'm not sure what to expect.
Okay, thanks for making it here. We'rd almost done, but now for the real doozy and primary reason for making this thread as I cannot proceed without some answer. What's got me utterly stumped on how to actually execute this: WHAT KIND OF AMPS DOES ONE PURCHASE FOR THIS FUNCTION?
Adding channels to an existing receiver which allows it must be common practice, but I cannot find anything suitable nor any guides on the matter. I called Yamaha and the technician said I need 2 2 channel amps and not one 4+ channel one; one for the front presence and another for the back. He also said that they should not have their own volume controls. But I cannot find ONE SINGLE AMP with comparable wattage (my receiver is 140w per channel, I'm sure the presence speakers could be a bit less though) and 8 ohm impedance. Literally zero.
Surely many audiophiles have accomplished what I seek to. But what amps could they have possibly used? Does anyone have any suggestions here? From what I see, my only option is to buy 2 full-fledged stereo receivers. But they'd be massive, and it would seem silly to have 3 AV receivers JUST to get presence speakers...nor do I really have the room and they'd have volume knobs.
There are so many power amps, but they're not usually rated for 8 ohms and (literally) only have a FEW watts. Like 12-25. And I've yet to come across any one which is volumeless.
An idea I had was to simply buy a standard, cheap 5.1 channel receiver and run all four from that. At least it would be only one extra receiver, and could perform other functions. But the Yamaha tech insisted that the front and rear presence would put out the exact same sounds if they weren't powered by seperate amps. Techs can sometimes have misinformation, and lots of it, so I'm not sure if this is really true as it doesn't seem to make any sense. Can anyone confirm this?
Wow!!! That was HUGE! Thank so SO MUCH ahead of time should anybody have any advice for any of these questions. Feel free to chime in on any or all at will. I don't expect anyone to have all these answers, of course, and what I'm asking about the amps may also sound a bit confounding so I'd be glad to explain that part again if need be. But with or without speaker suggestions my tracks are temporarily stopped as I don't want to purchase something incompatible, or that will damage the speakers I currently have (and still like). There seems to be no guides online that I can find for adding channels to a capable receiver.
For making it this far, and possibly responding, you ALL deserve stickers. Lots and lots of stickers. Thanks in advance (and I hope I put this in a good section).
