Dayton Audio RS75-4 3" Reference Full-Range Driver 4 Ohm
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.

Is there an 8 ohm version of this same speaker? I've seen the truncated version, but I'd love to get this exact one in 8 ohm.
Unfortunately no, we only have the round frame available in 4 ohm.

What is a prefered enclosure.
I am including two of these speakers along with a dayton DC25T tweeter and was hoping i could get some help with enclosure dimensions and port size and length. I am a newb i have software coming to help me with future builds but need help on this one.
The recommended enclosure volume for both of these is 0.08 cubic feet with a 1" diameter, 1.5" long port.
