DB players have been sticking their cabs up on chairs since time immemorial. Not only is it downright ugly on stage but at that height it’s not particularly effective. Getting the cab up to above waist level, or even up to the shoulders takes the output closer to the ears. Also the sound will be well above the point where the bass is most microphonic and prone to feedback. And I agree with putting a high pass filter in the chain to bring out the mids. That way you should be able to hear yourself clearly.
I’ve been using a low rise speaker stand - goes up to shoulders - with a platform on top. Mine is notched out to accept the Genzler 10-2 and drilled for a 10” Wizzy. That way no mods are required to the cab. And, ahem, it’s for sale in the amps and cabs section.
