You already buy them?

Typically (and I mean typically), ported boxes are louder (spl), sealed is more for sound quality (sq) and more power handling.

And typically, if your using one amp for all of them, common chamber is fine.

Says .5 - 2cubes each sub ported. I'd go with 5-6 cube box (if not bigger) and see how they do.

Dunno about port or tuning though for those

i bought them im screwed lol

but yeah i was thinking 5 cubes with w big slot port tuned to 32hz ???

 

[Anniku989 10+ year member]

I'd go with 5 or so, little higher tuning I'm thinking, 34-35 maybe. And a bunch of port //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I just ordered four, and I'm going to try sealed. The Kickers I had just take up to much room, and with a kid and golf clubs 15's had to go.

I'm a noob to ported enclosures, what is the benefits of having more port area. I understand that the larger the opening the less chance for noise, but what are the other reasons?

4 10''s in a sealed box will be fine... easy to make box, and unless your going for SPL it's not worth the effort to make a ported box

infamous

I got mine without a logo

 

[bad @SS chevy 10+ year member]

I have not got mine yet, but plan on putting them in a crx box, 4 cubes after sub displacement and port, 34 hz, 50sq inches of port.

What kind of power are you planning on using? I was going to use my MMATS 500.1 because I was thinking they may be a tad overrated but the Credence guy corrected me quickly and said they'll take 300 all day long so I'm going to use my BX 1500d.

 

[bad @SS chevy 10+ year member]

im goin to give around 1300-1500......

 

[a_steezy]

for four 10's with the power, i'd personally, off the top of my head go around 5ft^3 at 32-34 hz, kinda what anniku or whatever said but dont make a monsterous open port, 32 hz doesn't need that much, i'd say go to the re box builder and play around

 

[97srad750 10+ year member]

you guys think sealed is going to sound fine for everyday listening to a wide variety of music

and sports talk

5ft^3 net volume tuned to 36hz. sounds amazing. I love four 10's //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

BTW that is a 2 chamber design and the only reason I did it that way was to elimate the need for bracing. I had these in a comman chamber before but the port was designed/built poorly and they sounded like crap above 45 hz. Now they sound awesome. I listen to everything but country and I havent listened to anything yet that doesnt sound good with this new box.

and you dont need subs for sport talk...
