Thank You squeak9798 //content.invisioncic.com/y282845/emoticons/bowdown.gif.b85b23b82970bd22fb6b549c3392f016.gifYou aren't going to find too many "highly efficient" (95db+) mids that will extend low in frequency. Typically as you gain efficiency, you're going to lose low frequency extension.
It seems like you, me, and Hoffman Iron law understands this, while someone else refuse to believe physics //content.invisioncic.com/y282845/emoticons/redface.gif.62fdbfe1a101588a808c4cff71bcb942.gif.
//content.invisioncic.com/y282845/emoticons/word.gif.64b12e39f936af3b4fff38a1c0bd0244.gif x 10^3Stop worrying about the efficiency alone. As long as you provide enough power (~75w or more) to any "regular" efficiency mid it will have more than ample output for you. You're basing your entire decision off of a single spec, which is NOT the way to go about it.......and stop looking solely at that efficiency spec. It's only leading you down the wrong road.
