I gotta say, im kinda new at this, but i bought to 10" type-Rs and im VERY impressed. They sound clean and there is a whole lot of output. (you wont be winning any SPL stuff i wouldnt imagine :lol) but i have a fare sized car, a lackluster PA amp running them at like 500W RMS, in a sealed, prefabed POS badly sized box, and im still impressed. When i upgrade to my new alpine amp, proper box and 3 10" type-Rs, im told i am going to be blown away. just my $0.02.
