HDS3.1 vs. HDS3
To show you what’s different about the HDS3.1 from the previous version of the series, we ran a test and crunched the numbers. Read on to see how the two compare in terms of output, impedance, and power handling.
HDS3.1 Test Setup
For our comparison, we ran the woofers in a 5 cubic foot box with a 30 Hz tuning on a Q1-2200 amplifier (2200W @ 1 Ohm).
The HDS3.1’s 160 oz motor Gauss’s out 1000(G) or 1 Tesla (T) more than the previous version’s 145 oz motor. This results in better power handling and efficiency.
The stamped frame requires an average of 5.9% less power than the cast frame when operating below 40 Hz. Even with less power, the output was .13 dB higher than the cast frame. Compared to the stamped frame, the cast frame tends to be louder when operating above 40 Hz. However, even using an average of 1.7% more power above 40 Hz, it was .02 dB quieter than the stamped frame.
