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. You will get more bottom-end and more benefit by using a box a little larger. if you want to risk having to do a recone go ahead.

Mikhail Felton Posted May 30, 2013 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? im not sure... but u could try using this.. http://www.hometheatershack.com/forums/enclosure-volume-calculator/ Quote Vehicle: 2005 Kia Sorrento Ex Head Unit: Samsung Galaxy Note 10.1 Mids & Highs: Motorola KSN-1005s & Alpine SPR-17C Type R 6.5s Speaker Amp: Sony XM-ZR1252 Sub Amplifier: Pure Audio 3000.1 Subwoofer: Incriminator Audio Death Penalty 21" Link to comment Share on other sites More sharing options...

So if he puts them on a saz3500 amp @1 ohms 3500rms he would be good..

The Zv4 isn't out yet so there is nothing for it, or it's just not on sundown's site. I would recommend using Torres as a calculator for basic sealed/ported boxes.

Krakin Posted May 30, 2013 Report Share Posted May 30, 2013 Not double.. And they will need a bigger box just because of that unbelievable Xmax. When you account for the port area needed for them, the length of the port, stepping up the RMS by 250w, and other variables of that beast. Compare it to any other well designed box for another sub of the same diameter of course it will be bigger.

N9neMillahhh Posted May 30, 2013 Author Report Share Posted May 30, 2013 Well that's also just the Zv3, so im not sure that it'll be the same, besides that seems pretty small for them...Seems like if it was 1cube the magnet wouldn't even fit lol that motor is massive. I will be feeding them with a SAZ3500v2 @ 1 ohm so they will be matched for RMS. if not with a few extra watts, as you guys know sundown amps are champs.

Krakin Posted May 30, 2013 Report Share Posted May 30, 2013 In all reality if you don't have the electrical to support that amp along with Ohm rise you will be giving them less than 3500, but it's not wise to design a box expecting to account for those. It's better design as if you are on higher power: either for future upgrades or just common mistakes when assembling.

Mikhail Felton Posted May 30, 2013 Report Share Posted May 30, 2013 use this as a Guide for these subs.. 10s : 1.25 - 2 cubes ported12s : 2 - 3 cubes ported15s : 3 - 4.5 cubes ported18s : 4 - 6 cubes portedAt higher power err towards smaller; around rated power err towards bigger.
