Hi Bill, Is that an industry standard? The issue with debating standards are that there are many and conflicting - and all are valid for their use. We chose anechoic as it's a worst case scenario - you'll only get better from there on up. Having a large space (my measurement room...

Hi Bill, We use IEC 60268-5 for measurements, since ISI does have an international presence. And to the best of my knowledge, AES-4id does not require any specific test environment, but a minimum of half-space used for measurements (along with specified scattering and absorption coefficients...

Hi Bill, I prefer full anechoic space as it is "worst case" of what you can have; having done PA speakers for several "transparent" stage setups (where the floor was soft enough - or in the case of an outdoor venue made of actual perforated steel - it offered no real gain at lower...

Hi Bill, Full space measurement above 70 Hz, half-space below 70 Hz but shifted down and spliced to match. So this measurement represents what you get in full anechoic space. A single unit on the floor has plenty of extension; you tend to get a good 1/3rd octave extension as well as a...

Hi Bill, I'm sure you remember me...;) I'm the engineer who designed the drivers and cabs perhaps I can shed some light on what we're doing - and clarify that it's not smoke and mirrors and nothing to be seen through. It is pretty rare to see actual measured frequency responses for bass cabs...
