Hi Malcolm,
Can't help with the TL design but before you start....
You obviously want bass response down to 20Hz but if this is for
domestic (ie home lounge and not stage/auditorium) then why not consider
a sealed box design with "Linkwitz transform" circuit to equalise the
bass response ? http://www.linkwitzlab.com

Using 3 way active crossover, my design using the Peerless 831709 bass
unit in a 58 litre sealed box, acheives a response -3dB at 20Hz. The
box volume is uncritical and there is no tuning, specialised woodwork or
materials.
Electronic crossover PCB's are available as is all the design information.
The only drawback is that you need 6 channel amplification but the
results are well worth the effort.

Just a thought anyway and good luck with your project.

My efforts can be seen he http://www.fdj.org.uk/loudspeakers
