Does anyone know of a reliable encolsure calculator?

I want to check some numbers but Im not sure if there are any trustworthy sites.. Got any?

Alright and when your measuring the internal volume you take the width*height*depth and subtract the total volume of the port right? So if I have a box 14*14*22 for internal dimensions and a port 2.5in wide, and 14in tall, and 26in long(35hz), I would do the volume calculation and subtract the port volume from overall box volume correct?

Yes and also remember to subtract speaker displacement and any internal bracing.

Roger that, so subtract .18cuft(BTL) and would you suggest internal bracing? Ill be running maybe 1900Wrms or a lil more to each.. with 1in MDF and Ill screw it all together and use the sealant around the seams and stuff..

And thanks a lot for the help, very useful

With 1" MDF and a slot port you should be fine! I would use a quality wood glue like Titebond and clamps when attaching your panels. Don't over do it on the screws.

Ha quality wood glue, Ill drop $3000+ for a system but buy the cheapest glue possible Ill make sure of that and how many is too many would you suggest?

Depending on your box size it can vary, I like to stay 2" away from the edges to prevent the MDF from splitting (Pre drill) then anywhere from 6-8" apart from there.

So then what would I do to ensure the very edges are sealed.. just thought of that. Use the clamps and a lil more glue in the corners? And sounds like a fool proof plan to me.

Glue and clamps! Once the glue sets it isn't going anywhere!

You could try this out..... It runs in Excel, fairly accurate, I built my box by it, 4.2 cu ft. after displacements, tuned to 32hz... initial tests show it works good, the box is sounding great and the cut sheets were right on....
