I purchased this empty CAB as I wanted to build out my own with the speakers I wanted to put in it. Sure, I could have gutted my other cabs and replaced those speakers, but I love my other cabs the way they are, and I am not interested in gutting a higher end cab just to do some "speaker play" with various speaker type blending, so this was PERFECT!I decided on Swamp Thang and DV-77 for my needs and tests, so when this CAB arrived I was ready to rock and roll (pun intended).I opened this box, and it was perfectly packed. Corners protected, surfaces protected / foamed, and all was right with the world. It survived shipping without any damage or even a slight scuff anywhere to be seen, so the packaging was top notch.After initial inspection, I lined up the speakers with the screw holes, and this is where I deducted a single star. The holes were not lined up properly for a standard speaker mount... this has been noted in other reviews as well, and I can vouch for the same... HOWEVER, this is not a huge deal as I just used standard wood screws to secure the areas where the holes did not line up properly... problem solved without any real issue... so get some decent wood screws that are and inch or so long, and you will be just fine... the other holes line up with a majority of the speaker, so I used the included screws for all that and it worked beautifully.Once loaded up, and configured for my first test @ 4ohm for the speakers I chose, I connected several of my amps.... Most of your tone will come from your speakers, there is no denying this fact, and it's been scientifically proven over and over again... part of that equation is your CAB and it's materials, size, baffle, etc... let me tell you.... are you paying attention?!?!?!? THIS CAB SOUND PHENOMENAL!!!!!! Could this be a combination of the speakers I chose and my other gear? maybe..... BUT.... I decided to test to see if it was just a coincidence with what I had chosen... so I took my Vintage 30's out of one of my older Marshal cabs, and WOW was I amazed at how they sounded in this Seismic Audio cab over the Marshall cab they came from!The V30's sounded killer in the Marshall cab, but in this new Seismic Audio 2x12 cab they sounded even "heavier" with some more low end, and a growl that just turns my metal / hard rock love meter ALL THE WAY TO 11!TL;DR: This is a great CAB at a great price. It's solid, constructed really well, and the only thing I would modify is the mounting pattern for the speakers as they aren't perfectly lined up with modern speaker layouts in mind, but that is easily fixed. You can't go wrong with this guy, I can promise you that.
