Quick cab question

Simple question. If you have an open back cab can you simply cover it and make it closed back or is there more to the way they are designed than timber covering a hole? Would butting it up to a wall do the same trick? May sound silly but i don't know the answer

Re: Quick cab question

Likewise will taking the back off a cab make it open back

Re: Quick cab question

yes

taking the back off does make it open back

Carvin makes a convertible cabinet
see here how they do it
 
Re: Quick cab question

if its just a cab, then yes you can cover the back (or take the back off). butting it against a wall wont be the same since there will be plenty of air gaps. you may want to put some dampening material inside the cab. if you are talking about an open back combo you have to be more careful since you will change the amount of heat that can dissipate
 
Re: Quick cab question

Hey guys thanks for the heads up on that. Was thinking of closing up the back of my blackstar 1x12 before i went all drastic and got a orange pp112 instead. Just see if it helps the sound or if the speaker is just no good

Re: Quick cab question

Not exactly the same, but for a trial, why not get a piece of HD cardboard and duct tape it in place to see if it makes the sound more to your liking.
 
Re: Quick cab question

I did teh cardboard thing,it's kind of a reasonable facsimi... um,reference.
Def gave my Valvestate combo & a little more girth & focus.

My guy was out of baffle material when he gave it the once-over,I'd've gotten him to makes one that screws in tight.
Still on the table,tho,I'm sure the lack of air would certainly help.
A friend put some foam in his(edit:left open),it helped tame some of the highs.

You could also experiment with something like a 1/3 open back. That would still allow the amp itself to vent the heat better than closing it all the way up. May be worth trying if you feel like experimenting.
 
Re: Quick cab question

Seems like an external cab would be best for experiments

I agree unless I simply didn't want to tote around an extension cab. In that case, I wouldn't hesitate to cut up some scrap wood and rig something up to see if it's worth building a partially open or closed back panel for the combo. If it's for the bedroom only, I'd probably just pick up a loaded extension or maybe a 1x12 cabinet from Seismic if I had a particular speaker in mind.
