I'm amazed at how many say cables make a difference, but there again people have been known to recover from cancer when they were only taking placebo pills, so convincing them to hear what isn't there is a small task by comparison. One thing you'll notice about glowing reviews of dubious products is that they're never backed up by data. Not that pads don't do anything, they just don't do everything that's claimed. If they did there would be measured data on the Auralex site to back it up. They do have data on their room treatment products, and those products do work as advertised. If the Gramma and SubDude (it should be named SubDud
) did what they claim it does it follows that they'd have data on that as well. There is a chart for the SubDude, but I can't for the life of me figure out what it's supposed to be measuring, and measuring speakers and room response is what I do for a living. This is what they say it does: 'Its purpose is to prevent sound from transmitting through your subwoofer to surrounding surfaces
' and that's hogwash, pure and simple.
