A free Dynamo 500 sub came with some speakers I recently purchased. I put it in as SUB2 in a 7.2.2 Marantz 7009 system opposed to SUB 1 a Polk DSW microPRO 3000. Audyssey calibrated while plugged with tennis balls and both combined help give more depth to the sound. Without taking any measurements, balls in sounds much better and less boomy than with it ported. While its not a Dynamo 700, is there any harm in plugging the ports? Also, because of dual SUB, the volume of both have been tuned well below 50% and shouldn't be over driven as a single sub would be. I know a dense foam plug would be better but the tennis balls were something quick easy and perfect fit with just the right amount of friction.
Any thoughts or concerns? Has anyone tried this? I was thinking could have been better to pay the $200 difference and gotten the Dynamo 700 but not sure if they would have given me the $500 credit for the Dynamo 500 because it was a bundled deal.
