The new standard in all out musical performance, the RTi12 floorstanding loudspeaker is the epitome of "Real Wood, Real High Performance." Its three 7" woofers benefit from having the surface area of a single large woofer with the low-mass and acceleration of small woofers. So RTi12 bass response is tighter, punchier, more accurate; accentuated by the addition of PowerPort Plus Bass Venting Technology. | The new standard in all out musical performance, the RTi12 floorstanding loudspeaker is the epitome of "Real Wood, Real High Performance."

PowerPort Plus works with two ports (front & rear) and a series of internal "plates" (as opposed to PowerPort's single port) to further reduce air turbulence at the mouth of the bass port, and increase bass efficiency. PPP allows even lower frequency tuning and lower turbulence for less noise and distortion, and more big musical bass, even at lifelike volume levels. This technology delivers performance that vastly exceeds conventionally ported speakers with bass that you truly feel, as well as hear. |
