Frequency response tests were conducted on five speakers which are popular for D-style amps. Each speaker was mounted in a TL806 type cabinet and driven by the clean channel of a 50W non-HRM D-clone amp. In order to minimize tone stack effects and approximate a flat response, the amp tone controls were set to Treble-0; Middle -10; Bass-0. All effects were off.
Speakers were positioned in the same spot in the room and the set-up was left unchanged for each test - which hopefully resulted in uniform impact of environmental effects (room, mic, amp) so that measurements could be compared on a relative basis.
The speakers tested were:
- ElectroVoice EVM 12L
- Celestion G12-65 Heritage Reissue
- Eminence TonkerLite
- Eminence Deltalite II 2512
- Scholz Sugar Cone
