My comments in a recent post regarding the A7, A5 825 cabs. Modding to full Range . Add a supertweeter since that comp driver/horn does not really go much above 10KHz. Then add a subwoofer in the reflex cab below the 150-160 Hz MR horn. Just seal the connection between the horn and bass reflex cabinet and place an 15-18" driver in a bass reflex enclosure or an 10-12" driver in a tapped horn in there. You need to biamp the sub and adjust volumes. But now you have a 20-20Khz speaker. I did this once and it blew away the Wilson Wham which was more than a 100K dollar speaker system!

PS. Stiffen up/reinforce the bottom of the 825 cab and putty up the 511/811 horn to reduce ringing

luck
