Dayton Audio RS75-4 3" Reference Full-Range Driver 4 Ohm
i ordered one of these for my first project. My goal is to make a small bluetooth speaker using this as my only speaker. The box i made was crafted out of a few different hard woods and is about 5"x 5"x10". is this driver okay? what should i use?
I modeled a pair of these drivers in that enclosure size, assuming external dimensions and 1/2" thick walls. The volume works out very well for two ported, with a 1-1/2" diameter, 4" long port your tuning frequency would be 110 Hz.

Hello. Is this for one speaker or a pair?
These are sold individually.

I'd like to build a ported enclosure that would hold 2 of these as an 8ohm center ch. What would the optimal enclosure and port size be using 1/2" MDF. Is there an optimal spacing between the drivers? What can I use to block lower freqs?
I would recommend external dimensions of 4"H x 10"W x 4"D with a 1" diameter, 2-1/2" long port tube for a tuning frequency of 120 Hz. Spacing doesn't make much difference here, generally the closer the better to help with comb filtering. A high pass is recommended, something around 150 Hz or higher. Generally you can set this in your receiver.

Hi, what I'm using these speakers as dash tweeters. What capacitor or capacitor values would you recommend?
This really depends on where you want to cross it over. You could get away with a 200-400 uF cap and let it play as low as 150 Hz, or you could use something like a 5.2 uF and cross it closer to 2k.

I was wandering if anyone could help me with cabinet design. I was thinking a T Line or base reflex. I have tried the cabinet design software and cant figure it out. Any help would be much appreciated.
I can only help with a vented type design since we do not have TL software available. I am coming up with exterior cabinet dimensions of 6"H x 4"W x 5.75"D using 1/2" MDF. A single 1" diameter, 4" long port will tune the box to about 110 Hz.
