I've started a project with a gui**** friend of mine building cabs. We're starting with some basic guitar cabs then we'll get to a bass cab or two for me. We've got WinISD and are trying to figure it out (i'm still reading threads on it). One question i have that i haven't found the answer for is this: Why dampening? Most quality bass cabs are insulated inside, but most guitar cabs are not. What's up with that? What does the insulation do? Thanks in advance!
Guitar cabs can benefit from dampening too. It will remove unwanted resonances and distortion where it is unexpected and you don't want it. It's less critical for open-back cabs, but if you are doing closed back, definitely add the dampening materials. But, even open back cabs can benefit. I've used dampening in all my guitar cab builds.
you guys need more coffee this morning... the posts referring to unwanted resonances are for real the other guys just got out of the shower and maybe a bit damp themselves Good morning TBers I have read that "acoutistuff" from Parts Express is very good (and used it, a bit pricey) but have used fiberfill (stuffing for teddy bears) also (cheaper), and I have seen many commercial cabs with fiberglass building insulation inside also. Could Bill or anyone with more experience than myself comment on these three products for "dampening" cabs?
I’ve heard rumors beer works better than water but cost more. On a serious note - experiment with what you use for damping, how much you use (thickness, etc), and where you place it - because, it will change how the cab sounds.
Never use fiberglass building insulation. Rigid fiberglass is the best material, but not easy to find. Open cell foam and polyester batting are slightly less effective but available at any fabric store or Walmart. Acoustistuff works well for stuffing sealed cabs and transmission lines, but not so much better than polyester pillow stuffing to justify the high price.
Rigid fiberglass is also the same stuff used in good bass traps and etc - and if you can’t find it locally you can order it direct from Owens Corning, or Amazon.com, and etc.
this is the worst thread on a serious question. clean up the pointless posts and we've got maybe 3 serious replies.
