Those look kinda cool. I did a repair job on a set of Allison 1's with pretty aweful cabinet damage. After the repair, the guy then admitted that he had a dog that kept pissing on them.
I rememebr the Allison 1's, bought a clean pair at a yardsale for $5 and sold them for quite a bit more on eBay, I think $90??? This was at least 8-9 years ago. They were way to little for me to use
I think Allison liked to make speakers that had top-firing elements with the front. Missed some Allison Four(?) cabinets a year or so back when I was looking for something DIFFERENT.
