For the listening experience, the room is as important as the speakers. A good or bad room can make or break the sound. As for wire guage, I run 12ga to everything. I have about 90 watt continuous capability to my main channels and 1200 watt continuous to each of my subwoofers, and about 4000watts peak capability. The thing is, one day I might want to crank up the power to my mains for some extra headroom. High power amps are dirt cheap these days. You could do 8 channels at 1200 watts each (2 ohm) for under $1000 using Behringer inuke amps.

Over a decade ago, a friend and I built a 2x500W subwoofer with a resonance box of more than a cubic meter (it was a gag for the local club). That would have shaken the goddamn house apart, and we hadn't even ever cranked it up to a 100%. What are at least two 1200W subs good for?

They're 13cu ft ported enclosures each with an 18" driver. Basically I wanted IMAX quality sound at home, I exceeded that by a good margin. The theater system doubles as a music system for the attached bar room. Funny that the bar room seems to be a giant bass peak, so you get a bunch of extra bass back there without having to turn it up.

Even with the duty cycle of film content you're very very unlikely to actually be putting 1200w continuous into them. The amp may be rated for that at a nominal impedance but I seriously doubt a reflex loaded 18" maintains a flat impedance curve especially at tuning frequency, and even top end professional drivers would exhibit thermal compression at that kind of input voltage over a decent length of time. Even the AES standard used by most manufacturers only tests for 2 hours in free air over a relatively narrow band.

Even the AES standard used by most manufacturers only tests for 2 hours in free air over a relatively narrow band. Below the tuning frequency I can't give them full power, they reach x-mech pretty quickly. Luckily I have enough room gain that I don't need to. I've never measured how much power I'm putting through them. For normal movie listening I doubt I'm feeding them more than 50 watts. At demonstration levels where the subs are hitting 118db peaks they're probably getting 3-400 watts.

Nah the setup is in a concrete basement. Can't really hear it from outside except for the windows rattling. Either way I don't listen that loud very often. There is a guy on avsforum.com, popalock, who has 16000 watts powering 16 sealed 18" drivers. I feel sorry for his foundation. jonathan fucked around with this message at 18:04 on Nov 4, 2013 |

longview posted:This is actually shameful because you wired that up completely wrong, if you'd used a pair per channel it would be completely acceptable since it'd be (in practice) a balanced transmission line which has pretty good rejection of EMI. As is, you're probably getting some of the benefits compared to straight unshielded wire, and if it works don't gently caress with it. If you'd put a noise power source instead of a solar panel you'd probably see more crosstalk. I guess film sound is pretty forgiving. It's actually 4 matrixed channels. There's a poo poo load of crosstalk anyway, but that's because the slit optic azimuth is not adjusted properly. My projector was only ever designed for a photoelectric cell. The solar is an afterthought.

Does having three dedicated lines mean he re-wired his house so that the stereo, amp, and something else have their own dedicated outlet and breakers?

One for the pre-amp and sources, and one for each of the two 1200w amps that drive each speaker. If he does actually drive them at full power at times, it's not 100% insane to have dedicated breakers for them, to avoid tripping the breakers for the rest of the house. 2400w in a normal-sized room is hugely excessive, though.

Dedicated lines mean poo poo, beyond distributing load on multiple breakers, because they'll be connected to the same mains.

For reference quality bass, not out of the question. Even still, a breaker will pass double its rated current for 30 seconds (I think) before tripping. So with music or movies, the likelihood of tripping a breaker is pretty slim. If you're doing sine wave stress tests on an amp, that's another story. I operate my 2200 watt continuous sub amp off a 15a breaker and haven't tripped it yet. I'm sure Ive exceeded 15a for short periods.

I think it's completely possible to build a power strip that can't handle x amount of poo poo, and audiophile gear is often built to lovely specs so I'd be worried too.

Are you content living your life, believing that $10k power cables is all there is? Or do you want to take the red pill, and see how deep the rabbit hole goes? Holy gently caress: http://forums.anandtech.com/showthread.php?t=2332488 "My Bathtub Water Cooling System Project for Audio System" Just read that thread. It's not too long, and just mindbogglingly amazing. Here's a sample video (warning, this is Masaokis-level of mental illness): https://www.youtube.com/watch?v=osT8DHpfUz0 Please note that he believes this to be the most cost-effective solution, since he is "broke" after spending SIXTY THOUSAND DOLLARS on power cables for his ~$800 speaker setup hooked up to a near-worthless (at this point due to the age of the componenets) HTPC.
