I was hoping to better understand the ways a cabinet affects impedance measurements and how to quickly (reliably) measure drivers. so a couple of questions: 1. can I measure a (8 ohm) mid-bass driver and (4 ohm) tweeter (2-way or 2 and a half way) at the same time (wired together) to gain a sense of how the impedance of the tweeter affects the mid bass and vice versa or do the need to be measured separately. 2. assume two cabinets - with differing dimensions (A and B) - yet same internal volume (1 cu ft) - will the measurement for the same driver in box A be the same as box B and if not what is affected. 3. in terms of the cabinets in 2 above - do you have any ideas about making a measurement rig where it is easy and cheap to quickly change a box volume and measure the drivers incrementally... if so could you share ideas on such a rig? 4. in three above - if if I used magnetic strips to hold the box together - would the presence of magnets interfere with the measurement enough to rule it out as a construction method for testing? 5. similarly - would the relative positioning of the drivers (tweeter to mid-bass) also affect the measurements in terms of destructive interference across frequency range or could that for all intents and purposes be ignored got a few other questions - but this should get things moving (hopefully) Thanks!
