Fountek FR58EX 2" Neodymium Full Range Speaker Driver
Hi I am making some bass reflex speaker based on your recommendation. They appear to be rear mounted drivers, is this correct? I plan to use 18mm ply should this be rounded/ chamfered or is it too thick? Thanks Simon
These are designed to be rear mounted. I would recommend rounding or chamfering plywood that thick.

I've made a design for a compact portable speaker, and I am planning to mount these drivers into a speaker enclosure that measures roughly 1,2 liters or 0.042 ft.³. What would be the most reasonable ported option?
If you are mounting two drivers in that enclosure, a single 1" diameter port that is 4" long would tune the enclosure to about 100 Hz.

I bought a pair of these and am ordering Birch Ply to build enclosures. I want them to be as small as possible, but with as decent low-end response as possible. What internal dimensions should I use, and should be ported/vented?
If you are looking for as small as possible you will want to go sealed. This will have limited low end however, so you will have to choose which is more important to you regarding size or extension. I would recommend sealed dimensions of 4"H x 2.5"W x 1.75"D. If you chose to vent them, I would recommend 5"H x 2"W x 4-1/2"D internally. A 1/2" diameter port would need to be 3" long for a tuning frequency of 99 Hz which will give you a useable response down to about ~75 Hz.

is this magnetically shielded? Since many have pointed in the reviews that the magnet is very strong. Thanks.
This uses a neodymium magnet so it is self shielding. It is very strong, but all of the magnetic field is in the voice coil gap. Neo magnets have a very low stray field that will not effect CRT monitors like a ferrite magnet would.

is this water resistant
Yes, this is made from materials that will not be affected by getting wet.

weather resistant? fr an enclosure dimension of 7(W)x4(H)x3(D) external sealed, hw well 'll it perform? if I hv to improve on dat, 'll a vented up d results? wat 'll b its port dimensions den? also, can dis PR-Peerless 830878 assist & reduce box size?
Those dimensions will work well for this driver sealed, but it will not play much below about 200 Hz. Unfortunately it will not benefit from a passive radiator. This driver is made from materials that are weather resistant.
