Very tall and slim baffle for single driver - will it work?

[sonorsnoopy]

Hi, i have played with thorsten loesch XLbaffle.xls and the program shows good results down to 60hz with a very tall and slim baffle (would like to avoid the flaps) 120" tall, 20" wide, and driver at only 32" height for better bass response. Will need to tilt the baffle 10 degrees to compensate for ear level.

Can i trust the program? I would like to have the slim baffle for the looks and probably for imaging, but my common sense tells me that it would not work.

i will use mdf sheets or do i need a sandwich design?

see the graph and the driver details in the attachment

I trust the program.

I have just tried a 134" high baffle with 1" width - the difference in bass response compared to 50" width is only 2db less bass @ 60Hz in the simulation... is that possible? acoustics? / physics?

has anyone tried a floor to ceiling baffle before?

Not with a single driver (lol)

Is it a single baffle, no box? I'd use a stiff material, a constrained layer sandwich. Something that tall is bound to resonate.
Then again you could use something less stiff to get it's resonance frequency as low as possible...
Experiment! Do both and pick the winner...

What kind of driver will be used on that 1" wide baffle and producing 60Hz?

I'm puzzled.

Well I don't rely the result of the XLbaffle.xls file from thorsten loesch. I will not build it. I will make the decware ZOB speaker. The driver in the simulation is the Davis Acoustics 20de8.
