The Signature 507 is just as slim as the 505, but stands 1030 mm taller. The increase in size is due to the use of dual woofers, allowing the 507 to feature not only a 170 mm mid-woofer but also two equally sized woofers, enabling it to reproduce deeper frequencies. Of course, it also includes the Hi-Res certified dual tweeter module with two fmax. The front panel, with its integrated sound guides, further optimizes the radiation behavior. The 507 is naturally suitable for use as both a stereo speaker and as a front channel in a home theater system.
