I am looking for quality and loudness, but quality is more important (SQ I mean). How would it be if I got two Lambda 12's? And what exactly are those Adire Brahma subs? Are they better than the Lambda ones? The reason I was saying if cost didn't matter is because I wanted to know what was the best, plus I have found the RF Power HX2's for $210 and the Eclipse Titanium's (these are all 10" sizes) for $300. It says the rms peak is 500 watts and the peak power is 1000, so you're sure a 600 watt amp wouldn't damage it? I just want to be careful with it. Thanks for all the input.
