The density of purpleheart wood makes it excellent for reducing acoustic resonance. As a result, the sub-bass through bass is increased ~2 dB, while following the same curve as the original, which peaks at 50 Hz. The lower midrange is decreased by ~5 dB, and while the mahogany version had a slight peak at ~600 Hz, the purpleheart has a smoother climb from 500 to 1000 Hz. The midrange proper is essentially identical to that of the mahogany, the upper midrange is ~2 dB less throughout, and the highs are slightly more emphasized. Peaks and valleys are positioned differently than on the mahogany, but their magnitude is similar. As for the super highs, while the mahogany falls off at ~14 kHz, the purpleheart maintains presence through that range. Finally, CSD graphs of the mahogany showed some resonance at 3,000 and 6,000 Hz;
