Your links aren't working for some reason. At 2.25ft3 a 4 inch precision port needs to be. 10.90inches to tune to 33hz this displaces about .08 ft3. I can't find a displacement anywhere let's say there about average so .03 per driver so .09 for all three. To get 2.25 you need to build an enclosure with a gross volume( before all displacements) of 2.42 ft3 that's without bracing.

The easiest way to do it is download Torres box calculator.

Hey guys! Really hate to bother again, just want to make sure i do this right the first time and to make sure i dont waste my time and money. Would you mind checking it out? Im building this weekend and will post it when im done! I have sketched the box on Google Sketch up. In the link is a sketch up, The box specs in Torres, and the output levels in WIN ISD. please tell me what you think? thanks so much.

port on the same side as the subs ?

Hi brian, is this something you would not recommend? My thought was, if i faced it with the woofers, it could use the trunk area as a small box to amplify the sound. Also i cant really put it on the sides or the top, because it will be firing into a wall. Should i face it backwords?

I personally would go larger sealed to obtain the SQ your looking for. I would look for a free download for torred tuner It is a much better tool than the RE Calculator. It allows for extra baffles, bracing, sub displacement etc.For first build I would go sealed go larger if desired if you dont like go with arrow ports

tommy, what volume did you have in mind? im open to all sugestions im new to the game and want to learn. And hello to a fellow Marylander!

I pm'ed you back after looking at your Torres screen shot I would go with 2 4 inch precision ports only problem is your going to have to make the ports roughly twice as long and make the box bigger to compensate for the added port displacement.
