Dayton Audio DCS305-4 12" Classic Subwoofer 4 Ohm
Im planning to build a box with this driver and the SPA250 Dayton Audio plate amp and how do i tune the box using 2 ports (to match the rest of the system) for an F3 in the 30Hz zone??
I would recommend a 3.8 cubic foot enclosure with two 3" dual flared ports that are 17" long each for a tuning frequency of 24 Hz and an F3 of 24 Hz.

I am trying to find a replacement for an Audax HT300Z2 which is in a ported enclosure with an internal volume of 2.37 ft3. The port has a diameter of 4" and a length of 7". I am not sure whether this Dayton would do the job. Thanks for the help

I have two speaker cabinets with a internal volume each of 3.67 cubic feet. Port internal measurement is 4.25 " in diameter by 10.5" in length. I can adjust port size if necessary. How close am I to making two DCS305-4 speakers work in these cabinets?
The volume you have is perfect. The vent isn't bad, right now they are tuned to about 27 Hz. You could theoretically extend the ports to about 15" for a slightly smoother roll off and a tuning frequency of 24 Hz, but this is something you can play with to get dialed in to where you want it.

I'm interested in pairing this with the dayton 250w plate amp. Can you tell me what the optimal size would be for a sealed box in order to get a Qtc of .707 and the Fs down to 35hz where the bass boost of the amp kicks in?
The recommended sealed box for a Qtc of .707 is 1.14 cubic feet.

If placed in a down firing sealed box and paired with a marantz ma-500 amp. Do I need a low pass filter? If so do I need a high pass for my mains, which both have an 8" mid woofer( response goes down to 37hz but I was thinking of cutting that around 50)?
A low pass filter is recommended for any subwoofer application, although the frequency will be ultimately determined by you, depending on what will blend the best with the rest of the system. Subwoofers are usually crossed around 80-100 Hz.

I have a Paradigm PDR12 with a blown driver. Box is about 2 cubic feet with two 3" dia. ports 9 1/2" long. Amp is 150 watts, don't know ohms. This speaker is the right size to fit. How do you think it will do?
The enclosure you have is currently tuned to a pretty high 39 Hz which will cause a bit of a peak for this driver. If you seal up one of the ports it will perform much better. I would verify the original driver impedance, but if it is 4 ohm this Dayton will work very well.
