Hi all. I'll try to make this concise. My cabs of choice are my old school Carvin 210 without a tweeter and a newer Carvin 410t. They have the same speakers in them. I have used one or the other depending on the volume/room size. Sometime around 1999 my Walter Woods head blew out the cones in my smaller cab. Since 99% of my gigs are on that cab I just ripped out 2 from the 410 and used those in the 210. Now I have hooked up with a rock guy and will be needing the 410, but will still be freelancing on upright and U-Bass, so I will still be using the 210 still, too. So, I will be putting the 2 matching drivers back into to 410 (will more used and less used drivers in the same cab even matter, or does it make a difference?), and need to pick what new pair of tens will go into my 210. I also just got an AI Clarus head that I plan on using with the 210 now, and it does 2 ohms. So I will need 2 4-ohm speakers (the backplate has a series/parallel switch that would select between 2 and 8 ohms with 4-ohm drivers, now with 8-ohm drivers it selects between 4 and 16. Question is this: what 4-ohm 10" bass speakers should I get? I plan on using either head, and would use it for upright and electric and U-bass gigs. I am looking for something fairly loud, not too "voiced" and clear. (note: I tend to prefer no tweeter and warmer treble for all instruments, so no extended treble range is necessary). Thanks!
