I was at Ron Anchak's shop (fEARful authorized builder), tested out a 15/6/1 and have ordered one. I am also going to order a 12/6/1 with a reverse baffle so I can use together if need be.
The use case for the above is the following:
1) 12/6/1 for small to medium needs
2) 15/6/1 for medium to larger needs
3) 15/6/1 + 12/6/1 combined for larger louder needs
90% of the time I will use either the 12/6 or the 15/6 alone. Maybe 10% of the time I can *maybe* see using both together.
I have seen pictures of the Tom Bowlus config (illustrated below on the left). I see that the 12/6 cube fits on top of the 15/6 nicely.
My question is, other than aesthetics, can one use a regular 12/6 on top of the 15/6 (Illustrated below on the Right)? I know they wont lock together so can put feet on both the bottom and top of the 12/6 so when put on top of the 15/6 it will not wobble or anything.
I will be using a TC Electronics RH750 so wont have to worry about the amp not fitting on the smaller profile of the regular 12/6 cabinet.
Why do I want the regular 12/6 instead of the 12/6 cube? Because most of the time the 12/6 will be by itself and I like the look of the regular 12/6 better than the 12/6 cube.
That being said I think aesthetically the 12/6 cube on top of the 15/6 would look better than the regular 12/6 on top of the 15/6, but that is something that will happen only a small amount of time and it really wouldn't bother me that much.
If I ended up using an amp with a larger profile, I guess it would just hang off the edge each side of the regular 12/6 by and inch or inch-and-a-half. Again wouldn't bother me as I would rarely be using the stack.
If there is something that will affect the sound please let me know. I don't think it will, looks like things line up in the pic. Also checked at Ron Anchak's shop, looks like a 12/6 regular and the 15/6 drivers line up correctly.
