I got my self 3x4645 (the ones with 2245h) today.
I would love to get a bit more VLF so I am thinking of "retuning" the cabinets to aprox 20hz Is 20hz tuning too low tuning for 2245h in a 4645?
Would it be OK to close one of the ports or will this create portsounds? Is it better to make the ports longer?
