You can try an 8 or 10 ohm resistor across the terminals of the MCM 10" driver. The Lil' Buddy driver sounds a bit darker, but the thick hemp cone tends to make the roll-off sound smooth. While it's fun to experiment, you can often save yourself some time and expense by using a good sim program upfront. It's helpful to think of the project as a system; one small change can affect everything. Enjoy!
