I would like to raise one of the amps I have about 6" off of the floor on a plywood made box.
Being a hollow box, is it likely to affect the sound at all or should I fill it with foam?
Cheers
Barry

Yes the sound would be affected by placing an amp on top of a plywood box and could sound quite horrendous.
Look at some of the old videos of bands and most will show some sort of tubular frame with very little actual contact with the amp, vox used this method successfully and fender used two legs which only sloped the cabinet so the sound was projected up.
If you are going to use a wooden box I would heavily soundproof the inside of the box and then some form of underlay/carpet combination on the top between amp and box.

Hi Barry, i'm interested in where this one leads to as I am in the process ( is that 2 x c or 2 x s LOL ) of building my own 2 x 12" closed back cab, and I am wondering just how high ( on a stand ) I can have it "on stage" so as to enable me to hear it and not deafen the bodies in front of me, although I propose to angle it upwards as well, all comments welcomed especially those with xp of the situation, back in the "good old days" I remember just plonking the AC30 on the stage and letting rip LOL, but times, they are a changing are they not.
Cheers to all.
Brian.

hi barry with my ac15 i put two lightweight 9" building blocks on the floor then a bit of 3/4" board across to form a bridge, then put the heavy amp on that and it worked out ok. this is home use only.

I often raise the amp off the stage floor but I do lose some bass. Usually one of the band's flight cases (about 1 foot high) is used to stand the amp on, then a decorative flag used to cover the box, but I have used beer crates or a chair at times. If the stage is not carpeted, there is always a piece of our own carpeting under each amp.
When Hank was using Matchless amps he had a shaped block of wood under the front of each amp to angle it up. I guess that he lost less bass that way. When he used the KCP amps whose cabs had an angled baffle he no longer used any blocks.
Regards,
Charlie

Charlie, thanks, LMAO here, if I build the baffle angled I will have no need to angle the cab also my amp head will still sit on the top, amazin aint it how we can't see "wood for trees" at times, must be a senior thing

Hi all
Several years ago (quite a few actually !) I went to one of the local "HI-FI" shops to buy a turntable. Whilst auditioning this on a purpose built metal support/table the guy showing me the turntable tried it out on what looked like a coffee table with thin tubular metal legs. The difference in sound quality was almost none, the difference in price was well over £100 pounds. (The coffee table was from MFI @ £4.99) !
The moral of this story seems to be that a wooden chair on a stage (as seen in old Shads photo's) works well with amps, but be aware of Charlies comments about carpet pieces & "lighter" bass.
The ideal stand would be a purpose designed solid steel, lead shot filled legs stand that would probaly cost several £100's of pounds & weigh about the same as a small elephant !
The wooden chair option is widely available everywhere that has a stage ( and don't need carrying in)
The Vox style tubular frame is a good option as well as the Fender style "tilting" legs
Hope this is helpful
Dick.
ps ........sad to say but I did buy that expensive turntable stand !
