6th orders aren't just for SPL they can actually be very musical. I've got a 6th now and it's got excellent range. fucking love it.

I'm lost ? It's not that difficult Let me know what brands of car audio lanyards you already have and I will send you some different ones free of charge. I have hundreds of them. I've got a DC lanyard on the way, I'd pay for shipping if you sent me a couple

Noticed you were from Iowa too. DD's like big boxes for sure. I've never used DD subs though. Hopefully this turns out well for you

I didn't read through the OP's post. Yeah, essentially that's a 6th order not a 4th. In order to be a 4th, you would build a sealed chamber to spec, and leave out the passive radiators from the SEALED side. then for the front chamber you'd put the passive radiators in to act like ports.

The front chamber would have the ports/passive radiators, the rear chamber would still be sealed.

I don't know what the deal is lately. there's been this obsession with tuning your box below 30 hz. I don't really see that as necessary. I think you'd be surprised at how much you can play below tuning

Have you ever tried woofers facing the seats?

OP have you already bought the sub? 15.5" would be cutting it very close for forward firing. unless you angled the face, i definitely wouldn't recommend upward firing it. It's gonna sound like shit (trust me i've tried). If you haven't bought the sub already, i'd suggest getting a pair of 12's. it would fit much better into the space you have.

To be a 6th, the rear chamber has to be ported as well. I don't know what post you were referring to.. i didn't read the one right above yours lol

I have no idea how you'd go about designing an enclosure with a passive radiator. I'd be interested in learning more though.

The ONLY reason you changed that is because it was suggested that he do that instead...

When you've done hundreds of design you start to be able to visualize just from the numbers lol.

ditch the RE calculator and download torres calc. it's a LOT more accurate.

like this

Unintentional stage dive!

x2, ported to the side.

4th orders aren't the only bandpass boxes i'd imagine it would be 6th order friendly

I would do a bolt per terminal, so 8 bolts total.

This is why you draw your enclosures out before you build them.

lmao Joe X strikes again.

PM me we can work something out

second link in my sig. make your speaker terminals like that so you're not tryin to shove 10lbs of shit into a 5lb bag lol.

the opening is 1.5" and the back part is 2"... well that's not right!

Way to crush my dreams, people. thanks
