In Topic: AR-6 Unfinished Pine orphaned pair arrived today

I don't know how bad your stain is, but... Oxalic acid in crystal form is what I used on these.

It also comes as an ingredient in deck cleaner, and it's easier to get in this form.

I still see sought-after speakers reasonably priced at my favorite thrift stores.

I would call it a consistent trickle. The first pair I found 20 years ago- AR2s-

started me in this whole vintage speaker thing.


These are purchases in the last 6 months.

2ax: $50

2a: $30

Old/original Large Advent: $35


They all needed some level of work, but it's easy to justify when starting

this inexpensively.

Thank you!


I've got caps and will order surrounds.


I have referred to that link before, but got confused, obviously. The late production shift in woofers is mentioned.

The cabinet does not look like the NLA.


How much fiberglass do these need?

I have the 30, but it's not the 30BF. These weren't sold in the US, as far as I can tell.

In mine, the woofer has no ribs in the cone. The tweeter looks similar, but does have the AR logo.

Here's another variation. The wiper is much more substantial,

but design limits the number of times it can be disassembled.

I used a brass screw to reattach the disk.
