I have a pair of Charney Audio Companion with Omega RS7 drivers. They are a single driver rear loaded horn based on the tractrix theory. I have owned them for 5ish years and used multiple tube and SS amps. They sounded the best on digital amps. If your in the NJ area your more than welcome to stop by for a listen. I moved into a different Charney horn and would like to sell these. Price is well within your budget.
