It will be best to determine correct phase when in the listening position, so this process will require walking back and forth to the REL if determining phase orientation alone. If the impulse lags the speaker’s response or if it sounds like the impulse is late, then the REL is out of phase. Sometimes is helps to concentrate on the leading impulse of the bass note, noticing if it is timed with the speaker. That is, when the position is working in harmony with your main speakers, reinforcing bass not cancelling it. Now move the phase switch from 0 to 180 positions and listen for whichever position is loudest or fullest. This should be 15 to 18 clicks from minimum (10 to 11 o’clock) on the High/ Low Level pot. At this point turn the High/ Low Level control up so that both the REL and speaker are roughly equal in volume. This should be at 20 clicks from the minimum setting (12 o’clock) on the Crossover control. While playing music with true low bass, adjust the crossover to a point where the REL and the speaker are sure to share frequencies. Keep in mind that the right phase is whichever position (0 or 180) is the loudest for fullest. With the REL in the corner the first step is to adjust for phase. The basic steps to setup are phase orientation, corner fine tuning, orientation, and final settings. Try to ignore all other music in the track, listen to the bass drum and its effect on the listening room. If working alone, corner fine tuning and orientation can be effectively carried out from the location of the REL. Working with a partner, one in the listening position and one at the REL manipulating position and controls is the most effective an efficient way to set up. This track is perfect for the set-up process and should be played at the highest reasonable level expected for system playback. This has a repetitive bass drum throughout that gives you plenty of time to move the woofer around. We suggest track 4 from the soundtrack to Sneakers (Columbia CK 53146). To begin the set-up process, choose a piece of music that has a repetitive bass line that is very low in frequency. REL QUAKE II REVIEW HOW TOPlease see articles covering how to connect via High Level for details. In most cases, when connecting two channel systems, you will be using the REL high level connection with the supplied cable. Low bass pressurization below 40Hz is best derived from corner placement, where the most linear and efficient low bass can be produced because the subwoofer is able to take advantage of the tangential (corner to corner) axis which is typically the longest distance in a room. Remember, we are dealing with True LOW bass pressurization with RELs. For best results, the REL should be placed in one of the corners behind the speakers. A REL will take advantage of the physical room acoustics to provide deep pressurization as no traditional subwoofer can. REL QUAKE II REVIEW FULLA REL is designed to augment the performance of FULL RANGE speaker systems in order to provide, in certain cases, linear response below 15Hz. REL products are not traditional subwoofers, but true Sub-Bass Systems.
