Just had the opportunity for a great deal on an Eden WTB300V (will upgrade the tubes to "Gold Lion" right off the bat), and am going to need to change out the drivers in my 2x10 Seismic cab. Have always liked the cab - very solid, durable and has sounded excellent with my Line6 head, but sounds like s**t with my all tube Traynor YBA200-2 so I'm going to need to change out the drivers and line/insulate the cab. Would like a few cost-effective opinions on what and where I should be looking. Figuring 400W speakers in series, upgraded wiring to14 gauge (as I do with all my cabs). Did my Seismic 1x15 like this and sounds as good or better than most 1x15's I've played - was easy to find a 400w Celestion-Pro not so easy to find high wattage 10". Thanks in advance.
