RAAL Ribbon
Replace the OW2 silk dome tweeter with the RAAL ribbon tweeter and you have a top end the is like a crystal clear window into the sound. It is almost as if there is no tweeter there at all.
Transmission Line Design
Classic TL bass response provides smooth and extended bass down to 38 Hz.

Flexible Placement
The TL design allows for greater flexibility in room placement than a standard ported speaker. You can get closer to the room boundaries without generating boomy bass.
Bass Extension
The transmission line cabinets allow the dual 5" drivers in this design to produce bass that is 10Hz deeper than these same drivers would if used in a standard ported cabinet. And they can be positioned more flexibly than a ported speaker without becoming "boomy."
