2.07 cubic feet too much for an HDC3 10?

just curious with this airspace i get 40.8hz of tuning i could add port length is it's at 21.5 inches and i guess that would consume some of the airspace and lower my tuning is this a good idea?

or will i be fine with the 10 in 2 cu ft on an saz1500d at 1 ohm

with what you gave, and the assumption that you meant 21^3 inches of port, then your tuning is at 44.8hz and after displacement (of port and sub) your volume of box is 1.9 ft^3. If you lower your tuning by increasing port length, it will make the box more peaky with the given volume, and less of an even response.

well

port width 3 inches

port height 11.25 inches

port length 21.5 inches

so should i add some port length ive got plenty or resin and extra mdf laying around along with right angle brackets so anythings possible

Wooooah there, 2.07 is too much. You'd be much safer with 2 //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I'd put it in 1.5 at the most. It's not like you aren't throwing enough power at it.

In all seriousness, that's too much. Since you're going for a SPL box, try 1.25-1.5 at your 40-42hz tuning.

well since the box is built

i can add port length and at the same time lower it down and keep the same tuning at about 40-42 hz
