I've got a 104HF, front ported version. It's essentially the same cabinet except the low end is projected forwards, and in my opinion a lot more efficiently, which I find fantastic for playing live. It's quite large for a 4x10, but due to the weight it's perfectly possible to carry it one handed... if a bit awkwardly! The sound is brilliant, Bags of low end, without it being muddy. Very clean, clear and articulate, with a lot of focus on the midrange. The horn is of top quality which produces very clear highs, and the attenuator is very handy if you want to turn it down/off.
I currently use it in a metal band with 2 guitarists, never once have I had a problem being heard. I cut through the mix without obnoxiously stealing all the sonic space. It's the highest quality piece of equipment i've ever used. It doesn't colour the sound at all. unfortunately for me, I've decided I like the tone to be coloured somewhat, and so I've decided to put it up for sale/trade. Interested?
