Peerless 830452 10" XLS Subwoofer
The manufacturer spec sheet shows a bizarre -10db dip around 25hz... Anyone have thoughts why this would be? measurment room standing waves possibly? has anyone noticed this with a sealed enclosure with their own use?
Anything below 200-400 Hz will be entirely room or measurement related, so free air anechoic measurements will not be 100% accurate below these frequencies depending on the room size used for testing. Chances are this driver was measured at both near and far field and then spliced, so this could be a phase or reflection related anomaly with the microphone.

The optimum cabinet size listed on the description...is it in error by one decimal place? Is Vented Optimum 1.2 cu.ft.?
This volume is optimal, that is not a typo.

What is the optimum enclosure volume when using this driver with it's sister passive radiator? How much weight should be added to the PR?
Hello Matthew. My name is Eddie, If memory serves me right, 1 cubic foot is like the minimum for a 10" speaker. but for a Sub, I like 1.25 cubic feet for my enclosures. Anything smaller seems to make the Sub work against it's self. The louder you go, the more unpleasent it will sound. I am not too familiar with a Passive radiator? I would think it, that it wouldn't need further enclosure volume, being the Pressure from the active speaker provides the energy for the Passive radiator. I believe the 1.25 cubic feet would be enough though. If you wish to experiment, use some OSB to do a mock up, before you build the real thing. OSB is cheap and works ok for experimenting with different type of boxes.

What are the standard recommended box volumes for sealed and ported for this driver? For two in one box?
With a Qts of 0.17, I would not recommend a sealed enclosure for this driver. A vented design of 1.0ft³ with a 3" x 11" port yields an F3 around 39Hz. For two drivers in one box, simply double the volume, and use two ports of the same dimensions.
