That's Moab weight. You can get at least as good sound as Gaia from ordinary springs for around $30-50. But you have to shop around eBay hunting for the right springs, and then build your own platform. Which is what I did, and it was extremely impressive for the money. But it is also a lot of work. Two sets of Nobsound springs for about $70 will also get you Gaia level performance, and they can easily handle 135lbs. Best of all are Townshend Podiums, not cheap but totally worth it. As unlikely as that may seem from something so expensive, but they really are totally worth it. Search around two different guys went from Gaia to Townshend, all agree it is worth the extra.
But if not- springs!!!!
