Well I got the JL 10w3's and they sound great but...I had the good fortune to see an MTX sponsored vehicle with the 8000's and ...and...DAMMMMMMMMMMMMMMN. Those things are the sheet. I already have them on the way (4 T8108's). My sponsor was alittle pissed but he understands that the MTX do actually perform better than the JL's. So we got ahold of two T8128's from a competitor's store and tested them in accourdance with thier recommended sealed enclosure specs versus the JL 12w3's and well as you can imagine...we now will keep MTX 8000's in stock.
