Howdy folks, I'm long overdue for a few gear upgrades and I'm torn between two products and I'd like to hear your thoughts. For a few years now I've been getting around playing rock, metal & dance through a SWR WorkingMan's (now WorkingPro series) 4x10T. 400WRMS with a tweeter - pretty standard stuff. I love it's meaty bottom end and while the tweeter is a can be a bit harsh at certain frequencies it gives me the clarity I need live and adds enough sparkle to smaller stages to keep things from getting muddy. Oh yeah, and it's heavy for it's size. About 45kgs. After playing through a few 8x10" cabinets at gigs where backline has been provided I would really love to upgrade to a big 'fridge' style cabinet - not just for extra watts, but for better on-axis monitoring more than anything else. Enter the gladiators: MESA/Boogie Vintage Powerhouse 4x12 Mark Bass Classic CL 108 Obviously, I'd just make the call on sound alone, but I don't have the opportunity to hear the Mark Bass cab anywhere in Canberra. I *did* have an opportunity to listen to a Powerhouse 4x12" on Saturday and ****-me it sounded gorgeous. Still seemed to have plenty of attack despite the bigger drivers and the highs were smooth and crisp where my current SWR tweeter does add clarity but in a pretty crude and harsh fashion. The money difference doesn't bother me, it's the weight and design issues that are messing with my head. The new Mark Bass box would actually weigh 5kg less than my current box half the size and that's a big incentive, where I'd gain another 15kgs to haul around with the MESA/Boogie. (however, some suggest that an 8x10" is easier to lug in some aspects because they always have recessed castors to tilt and roll where you actually have to lift 4x10"s off the ground to get them around. That all sounds fine and good until you actually have to get it in and out of the car though, hey?) The other thing that ****s with my head is that the Mark Bass 8x10" is a more traditional form factor, however it's not a ported box, while MESA has opted for the kinda new and original 4x12" high powered driver configuration in a ported box. Has anyone here heard both per chance and able to shed a bit of light on the matter? My playing style is typically very guttural and aggressive. My signature sound is typically a fairly distorted one ala Nine Inch Nails & Muse, but I don't want to set myself up with a rig that mires my ability to play soft and sweet when the time comes. Lastly, I like the idea of a fairly transparent cabinet sound to give me a good indication of what's heading out of my rack to FOH, though that doesn't have to mean no exaggerated low voicing because let's face it, most big FOH systems out there are bottom-heavy. Thanks in advance for your advice, peoples!
