Default Passive radiators internal cabinet volume?

I'm building a small battery operated "boom-box' for camping or picnics in a park. I'm going to use two TG9 Peerless 3.5 inch drivers, and two 3.5 inch Peerless passive radiators. I'm wondering how much internal volume the cabinet should have?

I've noticed the many bluetooth speakers now available that have almost no internal volume, and have PR's. Does this mean I can make my boombox smaller, or will too small result in a big rise in the response around 100HZ? Any experts on this out there?

Thanks much in advance.

Commercial bluetooth speakers follow the same laws of physics and indeed have bad bass responses of themselves. They correct it using heavy EQ.
