what is the sensitivity of these?, I have a t-amp with 10W/ch at 8Ohms...

96db, but the factory recommends at least 20 watts to a max of 100. But tube amps generally are converted for every one watt a tube amp puts out is equal to 4 watts in a solid state, thus your amp is about 40 watts, therefore it should work fine. As with any sound system simply be careful that you don't distort the sound, distortion kills more speakers then distortion free high volumes.

Hank 51 and Thomas H. are correct, and I wholeheartedly agree with their comments. I've used mine as well with a high-powered vintage Quad (British manufacturer) amp, and they sound great. Just watch the volume level, as these guys have already stated.

Its possible that whatever you have them wired to cannot output to 4 Ohms. If you wired them to factory radio, it may only be capable to handle an 8 ohm load. That or if you have them wired to an amp, you may have the gain turned up too much, or if you have more than one speaker wired to each channel on the amp, you might be overloading the amp. Regardless, I wouldnt say it is the speakers, it is the device powering the speakers.

anything between 150 to 300 watt RMS per channel will power these speakers at 8 ohm I'm driving the Emotiva XPA-2 Gen 2 300W RMS 8 ohm pre channel

I do not know the sensitivity but your laptop can definitely drive them adequetly. They do have 50ohm resistance.

I wrote a review for them after buying 2 of them. match them with the SSL 4000.1 EVO amp and wire correctly... 4ohm and they will blow yer window seals out. if you try to wire down to 2ohm you WILL fry the VC's. 4Ohm is perfect and the 4000.1 EVO amp matches up perfect. just run them in series at 4Ohm and you will not be disappointed brother.

the amp is at 4 ohm load, 2ndly are you asking about the implications of series or parallel hookup, hook it up to stay at the 4 ohms,= series. read a bit on the net about series & parallel. try them one at a time, noting amp temp,! aka does the fan come on? mine never did, so if yours does your pulling serious juice & sensitivity how much pre-amp line voltage required. are these subs or full range & are they in stock cabinets?

I'm running mine on my stock OEM amp and haven't had any problems. I may not be the best person to answer this since I'm not putting a lot of power through them.

The amp rating is 30 Watts into 8 ohms. But I would not push the amp to its max rating. All consumer (low price) amps distort badly at max rating. You may be able to get 8 clean watts out of it. With the speakers you have 8 watts will produce sound pressure of 94 db at 3 feet. At 10 feet listening distance the sound pressure is 83.5 dB. So don't expect disco level sound with your speakers and this amp. I use this amp to drive computer speakers, listening distance is less than 3 feet and speaker sensitivity is 85db and they sound great.

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'm using the same amp to run 2 10" Pyle. Only have the amp cranked up half way and they hit hard

I don't know the exact sensitivity# but I have had these installed for a couple months now. I am running them with a 800 watt 4 channel amp, and they are the best I have had. They just keep on amazing more and more.

They are 34 OHMs. The are really efficient. I have run them off of several different devices and they will always go louder that I can listen without distortion.

I measured them when I got them and they were something like 2.6. These are designed that way to accommodate OEM wiring, which I smaller gauge than aftermarket, and low powered radios. Installed the resistance is over 3, but that is less than using 4 ohm speakers. Actually, amps get more control, but require more power with higher resistance. That is way home stuff is 8 ohm. In a car power is limited by the alternator output. For matching, look at the RMS Watt rating of the amps and speakers and try to match 75% to 150% of the amp rating. Speaker sensitivity will also be a clue. A 3 dB difference means twice or half as loud. So a proper Watt RMS and as high a sensitivity possible is a good general rule. These are rated at 93 dB so they are better than most. Sensitivity is the measure of sound at 1 Watt power from 1 meter away.

negative... I was running 20 watts to these high pass and one still blew in a week! these are not subs.

Yes- & the impedance will be fine, these are Awesome super tweeters & will extend your frequency response amazingly! they can sound a bit harsh, which I enjoy, But if you think they are a bit too loud you could add volume controls to them or add a different capacitor on the plus side of the input terminals (BI polar 2.2uf or so) - or just adjust the tone control of your amp/receiver! Well worth the price! great tweeters!

4/8 ohm they work great I put them in my jeep on the dash to project sound towards me when the top is down.... Now I can hear the music again
