Atlantic Technology has unveiled the 1400 SR-z, a dipole/bipole surround speaker designed for height-speaker channel applications.

Due to its compact size, the 1400 SR-z can be mounted above a system’s front speakers, which Atlantic says makes the 1400 SR-z “ideal” for use in home theaters with Dolby ProLogic IIz (the technology debuted in Onkyo’s new TX-SR607 receiver).

The 1400 SR-z is compatible with any Atlantic system without encountering soundfield discontinuity effects. Atlantic says the speaker is adept in either the side or rear surround channel positions.

It’s also selectable to either dipole or bipole operation to enhance the surround experience, depending on room environment.

The 1400 SR-z features a pair of 3.5-inch, full-range polymer-treated cone drivers that use High Frequency Assistive Radiator (HFAR) technology to expand their range.

The 1400 SR-z, which comes with a black finish, will ship in the second half of May. MSRP: $425 each

Other specs of the 1400 SR-z include:

• 89 dB sensitivity
• 8 ohm nominal impedance
• 110 Hz - 20 kHz +/-3 dB frequency response
• 10-100 watts RMS recommended power
• 12.25 x 8 x 5.375 inches dimensions
