Hiya, I bought a whole Hartke rig a few years ago. 3500 / Transporter 2x10 and 1x15 cabs. The 1x15 cab died twice while under warranty and went back to the shop. I kept the amp and 2x10 and replaced the big cab with a 4x10 by Ashdown -which I love. There is a good offer to get a new Transporter 4x10 cab, (which weighs 20lbs less than the Ashdown). Before I commit and probably sell the Ashdown 4x10: Is the Hartke Transporter 4x10 durable and reliable, or are there known problems with this range. I am worried after the 1x15 debacle (though the 2x10 is great). Any thoughts? Thanks.
