Default What a good speaker enclosure design?

Hey guys,
I have these two 3 inch speakers and a 4.5 inch passive radiator.

I'm looking to put them all in an enclosure with a battery. I'm an electronics guy but I have no idea about sound. What's the best setup for a speaker enclosure? I've read some articles saying the PR should be on the bottom and some that it should be elsewhere.

Thanks

I've moved this over to the FR section.

Is there any information about the 3" speakers? Can you show front and back shots?

I'm just not sure where to put the passive radiator. Is it ok to put it in the middle and have each driver on either side? Or should it be on the bottom of the box facing down?

Passive radiators should never be mounted on the bottom facing down (or facing up)
They are tuned with weights and that causes "cone sag" or the weight pulls the radiator
down via gravity. Always mount them on their side for this reason.

Running two full ranges always get them mounted vertically as close as possible together.
The passive radiator can be mounted below the full ranges to give it a more traditional look. Some passives are mounted on the back but that can cause problems if you wall mount them etc.

I have 2 full ranges and 1 sub woofer. Should I go driver - sub - driver. Or put both drivers on the front with the sub on the back panel? Not sure what the best option is for a single enclosure.
