How efficient are these? What is the recommended per channel RMS wattage range for the amp - min./ideal/max.?

Not sure of the technical specs, but I was running them with an older / cheaper amp and managed to blow them. My understanding is that it's not so much about how much power but how clean the power is - you blow the speakers when the amp starts clipping. The manufacturer was great, replaced them with no questions asked. I'm now running them on the same amp, being more careful. They're plenty loud.

I have 2 and only running 3000 watt amp and they sound pretty good and hit hard, I would say for the price they are a great deal.

I'm running these off of a 100W rms Pioneer amp and they handle it with no problem. They sound amazing with some power put to them. Hope this answers your question.

I'm no Tech, but I've spent WAY too much time researching this stuff. My understanding is that you never want to "under-power" your speakers. Remember, amps not only "put out" power, but speakers also "PULL IN" power. You should use an amp that puts out at least the same power (per channel) than your speakers are rated for. I believe these are rated at 85 watts, so your amp should be as close to 85 watts per channel as possible. In fact, many experts recommend using an amp that puts out at least 25-50% MORE power than your speakers are rated at. This way, you never have to CRANK the volume to get the cleanest, crispest sound your speakers are capable of without pushing them too hard. If I'm wrong, someone tell me why?

They dont need high power to get loud due to the high efficiency, however giving them clean power will give u the best sound quality possible. I have my set running off of 90 watts each from an older nakamichi amp and they sound amazing for what they cost. Having a high pass filter will help also.

well if your looking to go to the peak power 1600 true watts i have 2 on a 1200 watt amp and they sound good id probably get a 1500 watt mono block hifonics amp the one thats one ohm stable and wire the subs to one ohm and they will sound great

I used them with this tube amp (http://www.amazon.com/GemTune-Class--Tube-Amplifier-EL34-B/dp/B00DRUY6EG/ref=sr_1_2?s=electronics&ie;=UTF8&qid;=1449284595&s;r=1-2-spons&keywords;=tube+amplifier&psc;=1) that only has 10 watts per channel, granted, a bit more power than you are asking about. It filled a medium sized room well. Say 15x20 feet. But as others said, it won't rattle he windows. You could also give this inexpensive amp a try (http://www.amazon.com/dp/B00F0H8TOC?psc=1), the sound is surprisingly good.

Too much amp....these speakers are only rated for 200W peak. You'll likely blow them right out of the cabinents. You'd be better off with the SL-15s with that much power.

They are 1500rms. Between 750 and 850 is optimal for these. I have a 3200.1bd Zeus pushing 2 of these 12's. It's turned way down of course. I Listen at loud volumes all the time and I haven't had any issues. You were probably pushing it to hard. Try turning the amp down. If I didn't purchase these I would have chosen a different sub. If money isn't a object try sundown audio D2's. If you want to stick with L7's then just turn your amp down so because anything over its peak watts is just producing heat which will blow your subs every time! Hope this helped

I will agree with you, the rating seems low. I have them operating on 70 volt lines and am running it to 25 watts without any trouble. I'm sure it can go more. Remember, that 50 watts could be 5 amps...+_ depending on output voltage and load impedance

These are very efficient, so they would produce some decent volumes at 10 watts. Not enough for a large room or high volumes, but probably enough for listening at reasonable volumes.

Their amps are very overrated on power ( like their subs). So id say you should go with their 6000watt amp. It's not gonna put out anything close to 6000watts though. Just letting you know lol.

Though i'm not absolutely sure i "think" they're about 600 watts rms.. These things really do BANG!! YOU WILL NOT BE DISSAPPOINTED!! I bought one of mine used & it's now 5 yrs old & still works great!!

Running 2 subs on individual amps in my setup - 2500 watt peak mono class D - 2 ohm stable @ 2500 peak, 130+ db at headrest, no issues.

These are rated for 80 watts RMS and I wouldn't advise going over that figure. I'm running mine on a Kenwood amp at 50 watts per channel RMS. They sound excellent! They do tend to distort a bit with a lot of bass so I've installed base blockers on my set. Great choice if you're looking for sound quality but I'd look elsewhere if you're goal is to entertain the neighborhood.

I would say that RMS is around 200. I am running a pair on and amp at 175 watts per and they sound awesome!

That's 100 rms 400 peak, so your rms should be between 100-200 and peak output should be 400. You also want a buffer between amp peak and speaker peak. So you should get something pushing 150rms and 300 peak. I like alpine but there are plenty of good options. Don't spend less than 100.
