  • AR3 cabinet rebuild

    I have a friend that has his fathers old AR cabs. He had tried to get them restored , but they were at the repair shop for a year, and the repairman had him pick them up due to not being able to source proper parts. I told him that I would investigate options. He really just cares about the cabs, versus a restoration. What options as to potential kits that may work in them without messing up baffle step? The baffles are 14" width, and I believe they are 1.4 cft volume. Also, depending on the value of them, do any of you know of sources for resto parts? Thanks. Glenn.

    Try human speakers, they are into old acoustic suspension stuff. Otherwise, would he let you put ports in? A front port could hide under the grill.

        Thanks, D. I liked what you did with your Zingers, and had wondered how that might work in his cabs. He knows that we would have to redo the baffle, and ports are ok with him. I rebuilt a pair of Genesis Physics 210s, several years ago, with Human parts, but for the cost, and the sound, I would go a different route, if I were to do it today. I was thinking econowave, but the volume of the cabs is on the small side, and he doesn't want to use a sub. Glenn.

            There are smaller e wave designs.

              D, do you remember what the cab volume was on your ewave? I was wrong on his, they have 1.7 cft volume, so that dc300 may work ok in them. Great looking job on yours. Glenn.

                They're fine for music played with instruments, no deep sub output.

                Note the ports.

                Also, the 12" woofer looks like a very tight fit with that very thick baffle surround. The stock woofer appears to have the edges behind the surround. Of course there are numerous variations in the AR3 image search and I don't know which ones you are dealing with. That's why I mentioned smaller e wave variants.

                I'll have to have him take measurements of the cab to know for sure. Thanks!

              Look at the GRS 12SW-4HE to replace the woofer. It is a 12 inch woofer so would likely fit without much work. Looks like it works pretty well in a small sealed box and FR looks like you could do pretty simple crossover

                Thanks for the suggestion, Michael. That looks good for a small, w box, but I need a pre existing design that won't involve crossover design. The sensitivity is low, but I'll keep that driver in mind for a low cost dual distributed setup. I could see two of those in a bedroom setup, with a smaller two way monitor set over them. Glenn.

                  OK, here is a pdf about restoring the AR#: http://www.classicspeakerpages.net/l...3a_full_pd.pdf

                  If you want to rebuild and replace all the drivers, aren't many 3 way designs and fewer with 12 inch woofers that I know of. One that just came out is the Pit Vipers:https://sites.google.com/site/undefi...ers?authuser=0

                  The Pit Vipers is ported in a bigger box but crossover should work, Problem is the woofer is really designed for ported not sealed so bass will not be that deep given a 12 inch woofer. But given slower roll off of sealed and floor bounce bass should be ok to good, just not that deep.

                  Next idea, the Tarkus. Will need to fit 10 inch woofer in 12 in slot. I have used speaker spacers like this:https://www.amazon.com/Audiopipe-RIN...%2C102&sr=8-16

                  I use these to attach speaker spacer to cabinet:: https://www.amazon.com/dp/B07KVXL3LY...dDbGljaz10cnVl

                  Nice think about Tarkus, is the Peerless woofer works very well in sealed box so will get very good and pretty deep bass.

                    Those mount rings are a great option. I really like the Pit Viper design, myself, and might have already gotten the parts if I weren't trying to finish up a pair of 6cft coax's. My thought on the Tarkus is that the mid enclosure would eat up more of the woofer box volume. I'll see how far he may want to go on these. Thanks!
