I love how the bass tubes are so efficient..You don't need much power, maybe 50watts of clean power for the 8" and 75 for the 10" to have good sound, but you can also make them slam with a good amount of power. I had a pair of 8" tubes a few years back, then upgraded to a Collins 12". It was OMG kinda loud.
I appreciate the detail you put into your thread installs.
