Chrono 509 DC
The floor-standing 509s come with a shock-absorbing isolation base. The rear of the 509s includes a flared port near the bottom of the enclosure, and gold-plated bi-wire/bi-amp binding posts. The center-channel 505 has dual ports, and surround-channel 502s a single port. Both the center and surround speakers sport a single set of binding posts.
