I wondered that too. I think he had one listing for multiple speakers. Pics were definitely L-710 and he also had some Snell bookshelf speakers.
Maybe he had Dahlquist as well and edited the listing.
It was $225 for the 710's, $150 for the Snells. Can't remember the model. I'm not familiar with Snells. They were black, shallow bookshelf speakers. Looked 90's vintage.
