Um... no. I'm sure on large speakers what your saying is more that true. I've got a roll off filter on these which cuts in at 258Hz anyway so don't really want bass from them. Their only 4"!!
Sealing them with a rubber seal will make sod all difference i assure you.
But thanks anyway/
I assure you that sound cancellation also occures above 300Hz and up to 3-4KHz. Find a way to seal them and you'll see the difference.
I also have mine HPF at 300 Hz from the amplifier. And I remember one time when i careless passed over a speedtrap bump and the left speaker sound level dropped in half. After checking all wires and connections on the CD and amp, I removed the speaker itself, only to find it was dislocated and left a gap between the grill. When i fixed it back, sound level restored.
If you don't believe it makes a difference, go find a Cinq, unscrew the front speakers and listen to the difference by yourself, once the speaker is moved 1cm out, midbass is lost...
