There are nice used pairs of Joseph Audio Perspectives available for around $6k. Have them sent to Jeff Joseph for latest Graphene upgrade and you’ll have some awesome speaks for around $10k.
Another option that could save you $$$ is the LSA 20 Statement available new here discounted by the manufacturer for $4500/pr (retail $7k) that includes some nice speaker cables as a bonus. It’s said they targeted the Perspectives as their performance bogey, and they reach down to a very respectable 25Hz. Initial reviews of the new LSA models have been stellar, and they offer a 30-day trial, which is really nice. Hope this helps, and best of luck.
