I'm in the process of a large remodel and in the next couple of weeks I'll be having the contractor run the speaker wiring. My problem is finding reasonable places to put the speakers that doesn't require floor stands.


The room is roughly 24' wide x 30' long with cathedral ceilings which are 13' high and hardwood flooring.


To complicate matters since this is a great room, the listening sweet spot isn't in the middle of the room, but rather at about 1/3rd distance from the corner (8' from wide & 12' from long). It turns out that this is along the highest part of the room (the 30' beam runs approx 8' from the nearest wall). So I've got a lot of space to fill.


Everything I've read says to put the surrounds slightly behind and slightly above the listeners. That's not an option for me due to large sliding door on one side and kitchen cabinets/windows on the other.


I'm assuming that the surround speakers should be placed at the same height and across from each other (ie: equal distance to the wall where the TV is) which means I basically have two options:


1) Place the speakers above the window/sliding doors. This would allow them to be slightly behind the listeners, but about 82" above the floor. One speaker would be about 9' and the other 18' from the listeners. If the speakers are bipolar I probably have to mount one of the speakers a 3' or so from the wall so it's not sandwiched between two kitchen cabinets on either side of the window.


2) Place the speakers at the back of the room in the corners. This would allow them to be placed slightly above listening level, but 20+ feet away. This would have to be direct speakers to avoid the sound bouncing off the corners right?


In my research, I read that quad-pole surrounds like the Axiom QS8's were designed to be placed higher then normal surrounds? Would those + the first option be a reasonable selection? I'd be basically placing it above the kitchen sink in that case.


Also since I have such a large room, I was also figuring I'd need two subwoofers. Is putting one near the TV on the front wall and the other along the nearby wall 8' or so from the listeners reasonable? Back of the room would also be doable although the interference from our GSM phones would no doubt drive me nuts with such a long run.


Last, does it make sense to do a 7.1 setup and put the rear speakers on the back wall (18-20' from the listeners)? I know not much is 7.1 encoded so it may be a waste, but if I'm going to do it, now would be the time. Otherwise I'll use those speakers for Zone2.


Honestly, I know this will never be a "great" HT/listening area. I'd just like something half way decent which doesn't make me want to cry the next time I watch a great action flick.


Thanks!

as long as your surrounds are on mounts that allow you to "aim" them both down and at the listening area, the compromise positions should work fine.


If you use a good grade digital audio coax cable for the 2nd sub, the GSM RFI interference should be controlled. If the connection cable is not picking up the RFI, then it would be the sub's amplifier circuit doing it. Distance from the phone is the only cure for that. (or
parrish the thought....turn the "devil devices from hell" off for two hours and enjoy the movie...that's what voice mail is for
)


I think the sub in the back would work better than one close to the listening position - subs are supposed to be non-directional...but many can locate where the low frequency sound is coming from and the closer unit might be to overpowering and distracting. Barring that, put both up front, spaced across the front soundfield area.

Thanks for the info. That helps a lot.


I've uploaded my floorplan with rough speaker locations:

http://synfin.net/speaker_remodel.tif


I've calculated the volume of the main area (30 x 24) at ~7800 cu ft.


My current speakers are a set of satellite speakers from Cambridge Soundworks sized for our old townhome which was quite a bit smaller. Basically I'm woefully undersized for this new room and need to upgrade.


My current receiver is an Onkyo TX803. 7.1 w/ 105W/ch @ 8ohms.


Any suggestions on speakers? I'm not looking for audiophile quality (obviously my room has too many compromises to make that worth while) but something that is well suited for my space. I was looking at the Axiom Audio site and they're spec'ing the Epic 60-600 or 80-600 (4ohm speakers) for this size room. Getting pretty spendy. Honestly, I have no idea where Axiom falls in the quality range (I'm guessing upper-mid level?) so I don't know how reasonable.


I'm not totally against upgrading my receiver (I really would like one which upconverts component to HDMI and has a 3rd Zone) so that's an option if going to 4ohm speakers is necessary, although maybe an amplifier would make more sense?


Is 14AWG enough or should I go with 12 with these long runs?


Lastly, does it make sense to do the rears? I know not much is 7.1 encoded, but I was thinking for this size room having the extra speakers might help a bit- even if it's just background noise. Or with the new PLIIz (which my receiver doesn't support) should I plan to do the front uppers?


Sorry for all the newbie questions. I know the 7.1 vs. PLIIz has been beaten to death in other threads, but it seems very few people are dealing with rooms of this size.


Thanks!

if these relatively smaller towers will fit on either side of your TV, they would certainly help to fill the huge volume you are dealing with...the sale makes them a great deal. http://www.wwstereo.com/#/ecommerce/...103__0_0_0_-1/

Try mounting your existing CS speakers on stands so you can position them slightly to the rear and to the sides of the couch. The speakers on stands could live in a corner when not used (use simple phone jacks and plugs to create un-plugable speaker cables).


The rear speakers could come later, but they really should not be that far back from the listening area....so more stands ??? Only set the surrounds up when you plan to watch a movie.


Consider two 10" or larger powered subwoofers because one is either going to be massive or always struggle to create much effect in the large room.

There's plenty of room on the floor... should work. That is an amazing deal too.

While technically doable, not really feasible for various reasons (3 cats who like climbing everything in sight for example) and I'd like to take advantage of the 5.1 content available via our XM tuner.

Yeah, I know the rears shouldn't be that far back. As a compromise is it worth while to do though? I'll probably be upgrading my receiver in the next 12 months one way or another, I could always wire up two front uppers for PLIIz instead.


Going w/ dual I subs I think makes a lot of sense and wouldn't be such an eye sore as one huge one. Doing some searching here on the forum for people with similarly sized rooms a pair of SVS PC13-Ultra's seems to be about right... at about $3k though. You wouldn't happen to know of any other killer deals would you?



Thanks again for the help & advice!

Just noticed the eD A5-350 as well. It's like 1/2 the cost over the SVS, although people seem to compare the A7-350 more to the PB13-Ultra which is about the same price.


I wonder if they offer a wire mesh option like the SVS? One of our cats seems to find my existing sub (fires downward) far too interesting and having the exposed driver + claws seems like a bad combination.

the A5-350 is a 100 pound brute (your FedEx/UPS guy or gal will hate you), but they will sell you two for $1.4K.
Give Elemental Designs a call, they may have a wire cover for the sub, they make their own enclosures, so anything is possible.


Rears: it is always worth a try while you are wiring everything up. Directional monopole speakers would be best for that long throw.
