Box size for bass reflex

[DirkD]

Hi all

Hope someone can help me with a question.

I have a pair of Scan Speak 18W8543 woofers that I would like to use in a floor standing bass reflex box of about 34 l. Now the problem is that the reccommended box size for this driver is 7 - 18 liters and I would like to know what the effect will be of using them in such an oversize box. Any suggestions on bass tuning in my planned boxes?

Thanks

DirkD

Modeling the driver in WinISD would give you a rough idea of what might happen...

Go here and download the article on Alignment Calculations. Look for the section on Non-flat alignments.

Thanks noodle_snack. I did model it in WinISD and it looks OK to me,but I was wondering if anyone could perhaps comment on the effect on sound quality a non-flat alignment would have.

Thanks hornlover. It looks like a really great site.

Are you building two boxes with one Scan Speak each or one box with two Scan Speaks?

Hi there kelticwizard

I would like to use one woofer per 34liter enclosure, but maybe you could enlighten me with the results if you were to use two per box.

Thanks
