Some second thoughts... (Drive Units)
Yes, the pipe must be tuned to half resonant freq of the driver: the other half is done by the free space in the ceiling where waves reinforces without obstacles.
In my small dedicated listening room I've space for 35-40hz half waves, so I thought to a driver with Fs in that range with a pipe 240cm long.
Maybe BD15 is overrated, as it needs a 40cm width pipe minimum, and goes lower than I need, but it has the best spec.
The Pipe would have its own powerful amp and its own DAC. I have two DACs sourced by PC with common master clock, so all EQ would be done (live) in the digital domain.
