I have March Sointuva speakers on the way.
I am considering building a couple of powered 15"-18" driver subwoofers to fill in the low frequencies and take the load off the Sointuva's.
• My room is about: 13 ft * 15 ft * 11 ft (l*w*h)
• For both music and movies.
• I don't mind waiting for stock, as it will be a while before I purchase parts anyway.
• The aim is to build something with excellent neutrality/linearity and very low THD.
• Thinking of building the boxes with HDF or baltic birch, with a nice veneer on the exterior.
I seek advice on:
• What drivers to use: I am happy to spend a lot on drivers.
• What corresponding plate amps to use: ditto.
• Ported or sealed? I understand ported provides higher SPL output but is more difficult to design?
• How to design the boxes. eg what thickness of HDF, how to brace boxes, how to integrate ports.
My rationale for DIY subs is: I think they are probably easier to design than any other audio component; I want to spend a bit less than a commercial sub; and I have some DIY experience in building my stereo amplifier.
If in the end I don't DIY I think I would instead invest in a couple of Genelec or Perlisten or Arendal.
