markm1111 Posted March 3, 2014 Posted March 3, 2014 I am currently renovating our house, and am trying to figure out the outdoor audio (among other things audio related - more questions to come!). I have a dilemma I was hoping the fine folk of SNA may be able to help me with. Our outdoor undercover veranda is 11m wide by 4m deep. It will have a lounge area in one half, and an outdoor dining setting and bbq in the other half. What I am trying to figure out is speaker placement so that we get reasonable sound when in both locations. If I just have one speaker at each end of the veranda, we will only really hear one channel at a time. 2 pairs of speakers may be overkill, and I am not sure how to drive them. I have an Onkyo AVR that can drive a second zone of speakers, but the third zone needs its own amp. I didn't have this issue in the last house, as the veranda was only half the size. One option I have been toying with is having two single point stereo speakers, and running them in parallel off the AVR, but not suire if that is dangerous. Anyone have any clever ideas on how best to address this type of scenario?

lebowski Posted March 3, 2014 Posted March 3, 2014 (edited) our last home had a large verandah area similar size to yours at just over 13m long and 4m wide, completely covered with roof and plaster ceiling. I used Boston Acoustics - Voyager 6's mounted 8m apart high up under the eaves for bass reinforcement and powered them with a 150 w/p/ch NAD Power Amp. They sounded extremely good no matter where you were positioned along the 13m although there was about a 6m sweet spot in the middle. They could really rock too, so if you want to party and like it loud they are a good choice. I think local price is just over $1000 for a pair but I picked mine up direct from the US when the AU$ was strong at significantly less. Edited March 3, 2014 by lebowski 1
markm1111 Posted March 3, 2014 Author Posted March 3, 2014 Thanks Lebowski, that's good advice. I am trying to avoid that sweet spot in the middle, as it will mostly be a trafiic area. However, Boston Acoustics makes a single stereo speaker called the Voyager Metro II. I might see if I can find some comparisons against your speakers, as I really like the idea of being to crank it for a party.

surprisetech Posted March 4, 2014 Posted March 4, 2014 Choosing/Building speakers with dome mids and horn tweeters might widen the sweet spot significantly.
Gee Emm Posted March 4, 2014 Posted March 4, 2014 If you're going to use single point stereo speakers, have you considered just running speakers in mono?
Guest Peter the Greek Posted March 4, 2014 Posted March 4, 2014 What you want is a pair of these Hunt around for the previous (just disconinued) ADS82H Weather resistant, very good sound quality and very loud/clean, some in black or white and the white ones can be painted
markm1111 Posted March 4, 2014 Author Posted March 4, 2014 (edited) Thanks for the input guys. Pete, they look very interesting, will chase them up. I am moving away from the idea of point source stereo speakers. One solution I was pm'd was to use some sort of impedance matching switchbox to just hook up two pairs of speakers to the one output. I can find a lot of very cheap things along those lines, has anybody seen something of reasonable quality? Edited March 4, 2014 by markm1111
Gee Emm Posted March 4, 2014 Posted March 4, 2014 Haven't used it, but it may be local to you. $150 They have distribution in NSW I believe.

Yes, I have ... or may not be required if you wire the group of speakers in a way which presents an agreeable load to the amplifier.
markm1111 Posted March 4, 2014 Author Posted March 4, 2014 Yes, I have ... or may not be required if you wire the group of speakers in a way which presents an agreeable load to the amplifier. Some of the speakers I am considering are 6 ohm loads, which if wired in parallel would present a 3ohm load to the AVR, or even lower at some points, so I'm thinking that is not a good idea. If I wire them in series it presents as a 12 ohm load I think, which should be ok, but I wondered whether this may cause some time delay that would be noticeable. Thoughts? Dave, what is it that you have seen?

Flynnyfalcon Posted March 4, 2014 Posted March 4, 2014 I use Polk Atriums on a similar size deck to yours and have always enjoyed the sound they produce. They pump sound well and truly beyond the deck into the backyard also when the need arises.

If so, where have you mounted them in relation to the main seating positions you use?

Flynnyfalcon Posted March 4, 2014 Posted March 4, 2014 Thanks FF. Do you just have the pair of Atriums? If so, where have you mounted them in relation to the main seating positions you use? I mounted the speakers when I first moved into the house. Literally before doing anything else! The wife was a little perturbed by my priorities :-) Yes just the Atriums, and not the extra sub woofer which is optional. It could do with a little extra bass, like any smaller speakers can. The seating positions were not set in stone at that time, so I wasn't using any calculations other than keeping it neat and symmetrical. They are placed under the eaves approx 5 metres apart with even gaps to the edge. Probably not ideal for the current seating position, but when we have people over and scattered around the deck and backyard it's perfect.
Kaynin Posted March 4, 2014 Posted March 4, 2014 I run these on a deck of similar size - http://www.psbspeakers.com/products/outdoor-speakers/CS1000-Universal-In-Outdoor-Speakers They sound excellent wherever people are. Certainly a sweet spot in the middle of them, but they produce a good sound wherever you stand - i.e. considering their purpose, no-one is sitting there critically listening to the music, they're drinking/chatting and socialising whilst enjoying the tunes. Decent price too for what you get IMHO. 1

68premier Posted March 7, 2014 Posted March 7, 2014 (edited) Some AVR's have pre-outs for the 2nd zone to run external / slave amplifiers. This could alleviate your concerns re load on the AVR amplifiers. Edited March 7, 2014 by 68premier
