AVI 12" SL-300 woofers, any info?

I have for like 15 (or more) years 1 pair of AVI Sound International 12" SL-300 speakers sitting on shelves but can't find any data about them. On their web page which is super old, I found the only brochure which says they are 93db, 200watt RMS 4ohm. That company usually made car speakers but this woofer look's like any other good quality bass speaker, not like today's car super xmax boom woofers 🙂
Anyone have some more information about this speaker?
Or can be this used in some home speaker system DIY project? I was planing to make some 3way boxes for home and use this pair as subs.
