cab dimensions and frequency response - open back
Posted: Sun Jul 28, 2019 7:01 pm
Hi Folks,
Was hoping some heads could chime in on their thoughts/experiences on cab dimensions and response. I basically have had a new cab built for me and I just threw out some dimensions to a guy that made it for me. I went with an oversize 1x12, I am pretty pleased with the results sonically and the tone is very nice indeed and sounds very open and dimensional.. its loaded with an EVM12L. The only thing is.. it's quite 'tubby' and almost 'bloated' in the high bass/low mids... like that portion of the response is way fatter than the higher mids. I can only think of the dimensions as the culprit.. the dimensions are
L - 26"
H - 21"
D - 10"
What do you guys think?? Could this be because of the internal volume? Is there any way I could perhaps adjust this by maybe say fixing a plank of wood to the bottom of the cab internally to slighly reduce the volume?
Also worth noting, the builder used 1/2" plywood for the baffle and I asked for 1" as the EVM12L is very heavy so I thought I could use extra stiffness... he told me that 1/2" was easily strong enough and that it would sound better because it could move a little like the top of an acoustic guitar...
Im not sure but I would like to adjust this if possible, perhaps if I cant it might be worth adjusting the slope resistor in my amp head...
Look forwad to your thoughts on what Ive described! Thanks
