XPR-1 is great... for powering tweeters.
Not powerful enough for anything else.

I am not sure it has enough power? Hard to define enough power. Depending on all factors, the great explanation on the Emotiva Website on How Much Amplification You Need is a great guide primer. I think you should do fine with the XPA-100 given my limited information about what is involved here. emotiva.com/guides/audio-video/audio-video-basics-power-amplifiers |

Based on some of the posts in this thread, I've been using WAY too little power in my systems. I'm currently using 125 watts (Parasound) for my main system of Paradigm and ELACs and then a Pioneer Elite AVR (likely about 40 watts/channel) for the bedroom 5.1 system.

I would say if you are always going to second guess yourself about whether you have enough power, then you should buy the most powerful amp you can afford and hopefully that will cure the obsession.
But rationally, logically and technically speaking, an XPA-100 will supply all the power you will ever need. A home theater setup should have a sub and if you direct the low frequencies to the sub that's a big portion of the drain on any amp. If all you want is enough power, anything over an XPA-100 is overkill but if what really drives you is having a lot of power then like I said, buy the most expensive one you can afford.

I'll leave this here. This calculates theoretical max power you'll use assuming 6db loss per double distance when in homes it's around 3.5-4db. myhometheater.homestead.com/splcalculator.htmlFor a single 1099 away from walls you can hit 105db sustained output (not just peak) at 16 feet with 95 watts. Now that assumes a full range speaker which the 1099 is far from. And also assumes you lose 6db for every doubling of distance (which you don't). So if you want totally overkill for this speaker you'll need an amp that does 100watts @ 8 ohms assuming you sit 16 feet or closer to the speaker. Oh and just for fun you'll use less than 1 watt to hit 85db at 16 feet or less. The point behind these 99db efficient speakers is you save money on amps. (If you want to spend money buy subwoofers). Btw I also own 1099s. And just another thought. Amps measure their best at full output. If you are using a 300+ watt amp and listening 99% of the time with less than 1 watt that's not a good match. I would want the quietest and cleanest sounding amplifier which is often counter to high power. |

with 5 of the 1099s, all @ about 99db Sensitivity? 100 watts per speaker while running 10 watts continuous PER speaker with 100 watt peaks. Amp will have some crest factor over the 100 watts, too.
That's 109db continuous and 119db peaks. certainly enough to damage the speakers if kept up for long. Subtract for distance from speakers and Add for multiple speakers. The math is a little mucho,
but under no circumstances will you get lower than Nose Bleed levels.
That should be enough to put you in Jail for Disturbing the Peace. Or simply evicted from your house or Apartment.
Start now convincing your neighbors you're Deaf and maybe they'll cut you some slack. Just don't abuse the privilege and play too loud / late or early.
Maybe buy a 2nd XPA-100 and biamp?
Plenty of time later to buy bigger amps, but I don't think you'll need to.

Get a D Sonic mono amp. 1500 watts should work huh?
M3-1500M, 1 x 1500w
Price: $1,375.00

How about no longer bridging the XPA-2s? They're pretty robust. I don't buy the... you only need 1..5..15 watts arguments. Dynamics need power. Having more power than you need is RARELY a bad thing. 15 Watts gets him 108db. I suppose the further he is from the speakers the more power he will need, but how much headroom is really necessary here? 32 watts, maybe 64 is enough and he'll have headroom to reach 114db, 10db above THX reference peaks. Exactly: 15 watts is a lot for a 99db sensitive speaker. And 150 watt peaks adds another 10db. Certainly that's gotta be 'bout enough? Actually, I think 8 watts is 108db, 16 would be 108 @2meters and than add 4 more speakers and than room gain. Any way you slice it, 20 watts or so per speaker followed by 10x that for peaks gets you deaf or evicted or both. Maybe even broken speakers, depending on how long you keep that nonsense up. |

What IS the time limit of a thread? Just so I know in the future. 1 week? 2 weeks? 20 days? 1 hour? When you think its expired? Just curious |
