D2430K vs 2435HPL vs 2450SL-Be
Here are some measurements comparing the D2 driver with a 2435 and a 2450SL equipped with Truextent Be diaphragms.
- PT-F95HF horn, laying on the floor, upward-facing
- dayton mic (calibration not loaded!)
- ~50cm distance from the horn mouth (not precisely matched between drivers of different depth...)
- 4th order HP filter at 800Hz using Hypex AS100D plate amp
- no EQ
- all drivers are coming from ebay, but the Truextent Be diaphragm is new
The noise floor was pretty high, with hiss coming from the amp (no lpad or autoformer was used, and this of course impacts the lower impedance drivers more...).
Output level were adjusted in the filter to compensate for differences in nominal impedance.
