I’ve owned the Boleros a couple of times they are a large " book shelf " speaker.
They were nice sounding when they were around $300 / pair, I recently saw a pair advertised in the $800-900 range. There are a lot of better speaker available in that price range.
For reference, I’ve also had Valencia , 878B and currently have model 14’s . The 14’s work better in my smallish room when modified aka Audio Nirvana style.
