They may be unique and even a bit weird, but they are 100% badass! Over two years, people fell in love with the vertical mounting amplifiers, slowly but surely. They can mount vertically, horizontally and even upside down and still have adequate cooling. All the connections are on one side making sano installs a piece of cake. It wasn't until we discontinued the line that all of you D-Tower fanatics threw a hissy fit. We listened. We get it. We're bringing them back in late summer! You're welcome!!!"
