This is no joke.

your waf factor can be overcome, get the right size zip lock bags , fill with sand and then have HER pick out the cloth you cover your bags with, pick out a nice fabric, and you both win.

well mapman, next try a ten to fifteen pound sand bag, now that will make a big difference, does it surprise you that adding dampening and mass to your speakers will change the sound? why do you think manufactures make such inert speaker cabinets ? . one tweek I have done for years is zip lock bags filled with silica sand and then covered in nice cloth to make it look nice. depending on the speaker it can make a big difference, tighter bass, better separation and bigger soundstage, not bad for a very cheap tweak. Happy listening !!

I have listened to the beaks, could not tell a difference. sand bags do, however.
