I'm trying to tune the sub around 20hz. Right now with a 16" dia. sonotube I can go 128 liters with a 6" port 34-35" long. The SVS driver has an xmax of 14mm and I'm getting excursion of around 29-30mm at about 28hz or so.So I'm thinking since I never listen at really loud volumes I'll be OK.
What do you think?
Thanks,

Troy,
With that alignment and with 200W to the driver you should be safe to about 17 Hz. With sub sonic filter that should not be a problem with Xmax. You should be looking good to ~105dB (probably more, being safe) before that sub starts to bottom out at 28Hz. Over 200W the driver is going to bottom out giving the right source material. That looks like a good alignment, almost identical to mine, go for it! You will be able to bottom that sub no matter what alignment you go with (that is one of reason SVS invented the ISD) unless you tune it to around 25Hz but then you lose some of lower frequencies. Loud frequencies below 20Hz you would have problems, it’s a trade off. Higher tune, louder SPL, lower tune deeper but lose some output.
Good luck! It’s plenty loud at first until you get bit by that stupid upgrade bug!
