The Signature 507 is just as slim as the 505, but it stands 1030 mm tall, making it a bit higher. The increase in size is due to the dual woofers used, allowing the 507 to feature not only a 170 mm mid-woofer but also two equally sized woofers, enabling it to reproduce deeper frequencies. Naturally, it also includes the Hi-Res certified dual tweeter module with two fmax. The front panel, with its integrated sound guides, further optimizes the dispersion characteristics. Like all speakers in the Signature 500 series, it employs robust connection terminals that allow for the use of high-quality cables, as well as bi-wiring and bi-amping operation. The 507 is, of course, suitable for use as both a stereo speaker and a front channel in a home theater system.
