Final Adjustments

The Palladium Series loudspeakers have a phenomenal frequency response and superb dynamics, so playing large orchestral or rock music will be an awesome experience, but may not necessarily be the best guide in setting up the speakers. Your listening tests should be performed with a wide range of music, including unac- companied vocal and solo instrumental recordings with as little processing on the source as possible. A natural solo cello recording will reveal much about the bass characteristics of your room and positioning. The best position will yield smooth, extended bass without boom or smear.

Stridency in the upper section caused by underdamped rooms can be compensated for by hanging drapes or pictures on the walls to dampen reverberant walls; increasing the amount of soft furnishings will also help to eliminate high frequency “ringing”.

Room resonances are often structural. In such circumstances, good placement will minimize but not eliminate these resonances.

Apparent height is critical. The speakers have controlled directivity. Phase response anomalies are kept to vanishingly low levels by reducing the distance between the midrange and tweeter horns to the absolute minimum; nevertheless, if you are in the wrong seat, it may happen that the sound stage is not perfectly inte- grated. One remedy is to tilt the speaker slightly (if necessary by using a combination of long and short spikes) to aim the midrange driver at the listener’s ear to yield best driver integration. Take your time with this —the effects on some music may be small and quite startling on others.

Phase

Phase is not a matter of preference. Out-of-phase effects manifest themselves as poorly defined bass, poor stereo with very vague localization of instruments and voice, and generally fuzzy, ill-defined sound. A single- wired out of phase system is easy to detect; a bi-amped system with one element connected out of phase can be nearly impossible to track down. If you find that there are problems with the system that no amount of experimentation can cure, check all the loudspeaker and amplifier wiring carefully. If you have connected your speakers strictly in accordance with this manual, no phase problems will arise.

Conclusion

All the advice above will help you get the most out of these superb loudspeakers, but in the final analysis you should do what your ears tell you is right—you are, after all, the final arbiter of your system.

Happy listening!
