I've been looking for a light and powerful set of 115s and finally decided to save a bit and get two Mesa Subway 115s. Then someone mentioned the Ashdown RM 115 Neo 3s. These are $349 versus $1200. I'm playing sludgy rock and use a Tubedrve with built in tube preamp. Question: the ashdowns are lighter and cheaper.. are these good enough, or should I keep saving for the Mesas? Thanks
