Fostex FE164 MLTQWT Response -- Real & Modeled Near field measurements were taken with the cabinets lying horizontally on a workbench several feet off the floor. When they are standing, it is anticipated that some bass reinforcement from the floor will make the SPL response even better. The response is "flat" to 35 Hz. Martin has determined why it is 35 Hz rather than the predicted 40 Hz. Stay tuned... Modeled response is good to 40 Hz. People will say that it looks to be just a vented box, but as can be seen from the vented box simulation the MLTQWT has a much flatter response -- something else is definitely going on.(Vented model based on original drawings and done by the editor in MacSpeakerz) Figure 1: Measured Response of ML TQWP Figure 2: Modeled Response of ML TQWP Figure 3: Modeled Response of a vented box with the volume & vent of the MLTQWT
