Krakin Posted May 30, 2013 Report Share Posted May 30, 2013 (edited) Okay so you're going with only 2 10's?? You have 5.5cubes before displacement with the volume you posted. I would strongly recommend something bigger. You can fit 2 twelves, a 15" possibly 2 if those aren't you maximums. or get the 18". Unless you are looking for a 2 cube box for saving space why not go bigger? And addressing what Emmet pointed out, 10's in a correct enclosure won't sound any better quality wise than 12's, 15's, or 18's in correct enclosures.

Mikhail Felton Posted May 30, 2013 Report Share Posted May 30, 2013 What would happen if I tuned it at 30 Hz? The lower you tune the flatter the sound becomes.. I only see this good in home audio.. In a car you want to to bang with some lows so 35-40 hz would be best..

N9neMillahhh Posted May 30, 2013 Author Report Share Posted May 30, 2013 So 35 or 33 Hz?

Edit: Evil post It depends on the subs requirements on how big u need the box but remember the bigger the box the better the lows but at a cost of losing some upper bass frequency..

N9neMillahhh Posted May 30, 2013 Author Report Share Posted May 30, 2013 And cause I like 10s better, they sound better in my car. I just like em more. I might upgrade to the 18 when I get bored though! So the box for the 10s is gonna be 4 cubes @ 33Hz?

Mikhail Felton Posted May 30, 2013 Report Share Posted May 30, 2013 I would say 33 hz for a balance in sq and spl.. You will get the lows you need for rap with some bang.. But go for 35 hz if u want a lil more bang than lows..

So the box for the 10s is gonna be 4 cubes @ 33Hz? OK but don't forget 4 cuft before displacement.. So your box will really be like 5.5-6 cuft total..

N9neMillahhh Posted May 30, 2013 Author Report Share Posted May 30, 2013 How do I account for displacement? I'm gonna make a kerfed port and do 45s in all the corners, two front plates with an extra one to make em look sexier, and possibly some extra bracings. Once I get it designed I'll put it up with the specs I used and you guys can tell me if it's okay? I wont be back in town until Friday night. You guys have any advice or help with designing it further?

Krakin Posted May 30, 2013 Report Share Posted May 30, 2013 No not 4 cubes for (2) 10's! Based off the Zv3 the recommended volume for (1) 10 is 1ft3 after driver and port displacement. (2) 10's would be 2ft3. Putting two of those woofers in a box double their suggested volume is a sure way to destroy them when being ran at RMS. Remember only build a larger box if you are running on lower power. The higher the volume the less control you will have of the sub at higher power causing it to bottom out, and yes I know the Zv4 has an insane surround. Higher Power = smaller volume RMS Power = Suggested volume Lower Power = Larger volume.
