| Re: LLT Explained
The WHOLE thing under 4', or the tube length under 4'? You'd be hard pressed to get 240 effective liters trying to keep the whole thing under 4'. Figure 4" for the legs and 2.25" for the end caps and base plate and that leaves you with 41.75" of tube. A 6" diameter port that is 32" long will only get to a 17hz tuning, as effective volume is ~210 liters.
Could you manage a 24" tube that is 48" long? Using a 6" port that is 29" long, you could get ~15hz tuning with ~300 effective liters. Add in feet and caps and you're looking at ~55". Feed it 600 watts and you're golden. ~112db peaks in room shouldn't be a problem, and extension should be solid to the low teens.
NOTE - Man, that sonosub program Collo wrote really makes the tube dimensioning a LOT easier. A very valuable tool.
