A:AnswerThey require speaker cables connected to a receiver. I don’t see how you can connect them directly to a projector without going through the receiver first.
A:AnswerFrom what I understand they are, but it's really hard to find an exact answer anywhere on Yamaha's website. I've got mine in the bathroom above a shower, so we will see for sure....
A:AnswerHello Paul - March 2nd, 2018 - we are an AUDIO VIDEO installing dealer - so we have installed many of these speakers in the PALM SPRINGS, California area ... where summer temps can reach 118F > 122F, meaning that attics (often very shallow height-wise attics here in the desert climate) can reach SOARING temperatures during 3-4 hot summer months here. We have not had any problems (deteriorating speakers) with ANY brands in attic situations (due to intense heat), and we have been in this industry for over 30-years. Now sometimes, people BLOW-OUT speakers by not properly choosing proper amplifiers, and cranking the volume too high (beyond the capacity of the speakers). We think that you will be O.K.. GOOD LUCK !
A:AnswerCheck the specs on the MANUFACTURER'S WEBSITE - they provide all of these specs. If you want OUTDOOR speakers .... look into "OUTDOOR ROCK SPEAKERS" ... AS THEY ARE MADE TO WITHSTAND EXTREME TEMPERATURES ....

A:AnswerI woukd always prefer two speakers for a stereo effect. However, they will work by themselves. I would suggest operating the source (like a receiver /amplifier) in Mono mode. This would reduce the risk of you "losing" part of the music in tracks that rely on stereo effect. However, mono is not very hi fidelity.
