john_the_bass Posted February 1, 2010 Share Posted February 1, 2010 Guys who've built these - I notice some of you added a couple of the wedges in between the platfoam (and the pre-built Gramma Pad also has this). Is there any advantage to doing this or do they work equally as well without the wedge? Quote Link to comment Share on other sites More sharing options...
Al Heeley Posted December 8, 2010 Share Posted December 8, 2010 You can get dense foam disc isolation pads for audiophiles, £40 a set, to put under the feet of your hi fi amp, speakers and cd player that achieve similar principle to this. I cut up circles from an old foam-backed mouse mat and improved the sound of my rich neighbour's expensive hi fi significantly for the price of a beer. Go DIY'ers!

farmer61 Posted December 8, 2010 Share Posted December 8, 2010 I stand my 2x12 on a plastic beer crate, mainly so I can hear the thing better. Does this effectively do the same thing as a Gramma? what if I put foam on top of the crate? Quote Link to comment Share on other sites More sharing options...
Al Heeley Posted December 8, 2010 Share Posted December 8, 2010 It would certainly make it more comfortable when the crate doubles as a stool for tuning up. Go for it. Quote Link to comment Share on other sites More sharing options...
synaesthesia Posted December 2, 2013 Share Posted December 2, 2013 Bought a Gramma. Used it a couple of times then made my own. Foam shop sold me equivalent density foam. Built a bigger base to fit a carpet tile approx 520 X 520. Painted the 9mm board with duratex, and glued on carpet and foam. Works a treat, just like the Gramma. Tested with a 6U rack case, 1 X 12 and 1 X 18 sub. Would have cut a monkey grip but was too lazy, works fine like this. Plain and simple.

ambient Posted December 3, 2013 Share Posted December 3, 2013 [quote name='bassace' timestamp='1253648848' post='606084'] But do you think you need Auralex foam? I would have thought that any foam would do; nothing special about Auralex, I think. I'm using offcuts from rubber stable matting one and a half inch thick strips. Works very well. [/quote] No definitely not, once you start buying something with auralex on it then you're paying over the top. I bought some foam isolator pads from digital village for my studio monitors, they were something like £10 for a pair, they come in 2 parts so you can have them angled or flat, kind of like wedges. Anyway I compared them to a genuine pair of auralex and they're identical but without the auralex badge, and they're like £50 cheaper or thereabouts !

Rich Posted February 27, 2022 Share Posted February 27, 2022 (edited) There's been a length of the Auralex platfoam stuff lurking in a corner of my spare room/office for donkey's ages, so today I finally got my arris in gear and spent a very pleasant afternoon putting a DIY Gramma together. Turned out really well. Marine ply; foam; offcut of carpet; Evostik spray glue; staples/staple gun; corner plates; screws.

One of the foam pieces on my Gramma isn't as secure as it was (13 years of gigging so fair dos) and I could do with sticking it back down before moving it on. Was a bit worried about regular glue or spray adhesive reacting with the foam. Edited February 27, 2022 by Rich Quote Link to comment Share on other sites More sharing options...
Rich Posted February 27, 2022 Share Posted February 27, 2022 No issues at all. This was the exact stuff I used, in fact it's the same can of glue I used to make my previous Grammabodge well over 10 years ago. The foam is still stuck fast to that one... well what's left of it anyway, since the mice got to it... 1 Quote Link to comment Share on other sites More sharing options...

solo4652 Posted May 22, 2023 Share Posted May 22, 2023 I'm considering making an isolation pad to go under two Tecamp 12" speakers and a lightweight head, total weight of 27 kgs. I've been reading DIY threads on here and was all set up to buy an extra large bamboo cutting board, isolation foam, carpet tiles and adhesive. Then I stumbled across this at BAX: https://www.bax-shop.co.uk/monitor-isolation-pads/devine-mon-pad-03-monitor-isolation-pad-single?utm_source=google&utm_medium=organic&utm_campaign=surfaces&srsltid=AR57-fBXA8ub5UwpwPR6zsDhWuoVBY3DGnsBDJe_ZYoINoeAr7Hx8v1QxpE What do we think? Buy one and glue it underneath a chopping board (surface area of one isn't quite big enough to go under the feet of a speaker). Quote Link to comment Share on other sites More sharing options...

BigRedX Posted May 22, 2023 Share Posted May 22, 2023 I sold my real Gramma Pad a long time ago. There were a couple of places where my band played, where putting the rig on the Gramma Pad caused it to sway alarmingly in time with the action of the kick drum pedal, so I stopped using it at these venues. Strangely there was no difference in sound without the Gramma Pad, so I stopped taking to all of the gigs with no ill-effects, and finally sold it.

Matt Aaah, right. Good points. Thanks. Plan B is to glue these under a carpet-covered chopping board: https://www.bax-shop.co.uk/monitor-isolation-pads/nowsonic-shock-stop-s-studio-monitor-isolation-pads-set-of-2 Plan C is to buy this: https://www.gear4music.com/Recording-and-Computers/AcouFoam-Speaker-Cabinet-Isolation-Pad-by-Gear4music-Medium/2F4R?origin=product-ads&gclid=EAIaIQobChMIpO-In7GI_wIVEt7tCh0tqwjgEAQYBCABEgLYAPD_BwE Quote Link to comment Share on other sites More sharing options...

I've gigged mine a couple of times, both on wooden stages. I think it's cut out a lot of boominess from my tone, however I've also been trying different EQ settings on my amp and mixing the pickups much more towards the bridge.

PaulThePlug Posted June 11, 2023 Share Posted June 11, 2023 (edited) MDF... Carpet Tile... Foam Garage Floor Tile Edging Strips... Edited June 11, 2023 by PaulThePlug 2 Quote Link to comment Share on other sites More sharing options...
Ray Posted November 12, 2023 Share Posted November 12, 2023 There seems to be two main components to these contraptions - a wooden board and foam. Is the board necessary from an acoustic POV? Or is it just there to create a solid platform? I have a piece of very dense foam about 2” thick that I sometimes use under my bass cabs (2x Aguilar DB112s). It’s just the right size to fit between the feet of the cab. I’m wondering, if I glued a larger piece of carpeted plywood to it, so the cab’s feet sit on top of it, would it perform better sonically?

PaulThePlug Posted November 12, 2023 Share Posted November 12, 2023 Prolly not as the foam you have is full surface, between the feet, and ss long as the foam it not compressed easy enough for the feet to contact the floor. The board would be to ensure the feet don't just dig in to the foam... 1 Quote Link to comment Share on other sites More sharing options...
