My HSU subwoofer, operating on the same principles as all other ported bass enclosures comes with a SINGLE dense foam plug for one of TWO ports.
The sub is provided with a switch for 1port / 2port operation. I don't know what the internal circuit changes entail.
The manual says the switch is for 'Maximum extension mode' and 'Maximum output mode'
Not that it matters, but I run maximum extension mode, since I rarely go to nose-bleed levels.
