Boon Posted October 4, 2009 Report Share Posted October 4, 2009 The port is still far too long IMO. 8's don't work with long ports in my experience, they don't displace enough air to make the port resonate properly. Do 1 4" aeroport at like 12" long. Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...
kfx450r Posted October 5, 2009 Author Report Share Posted October 5, 2009 (edited) The port is still far too long IMO. 8's don't work with long ports in my experience, they don't displace enough air to make the port resonate properly.Do 1 4" aeroport at like 12" long. Hm well how do u calculate that. Precision port calculator claims a 4" flared port needs like 36" of length to get the tuning down to 33 hz. I know people tune 8s low, theres no way im tuning this thing above 40 hz...I do zero competitions and could care less whether it did good on the meter or not.

SPL2K Posted October 5, 2009 Report Share Posted October 5, 2009 You need to cut the port length in half and go along the back wall. "L" shaped.

Boon Posted October 6, 2009 Report Share Posted October 6, 2009 Disregard tuning You'll end up with stupid boxes trying to get an 8" sub tuned to 33hz. What's the Fs of the sub anyway? Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...

1992Chevy K1500 Posted October 6, 2009 Report Share Posted October 6, 2009 37hz i think Never tune below a subs Fs (at least, that's what I've always heard).

Well a btl 12 has a FS of 39hz and i dont know any one tuning their btls to 40+ hz unless for competition which i could care less about.
