False Info?

I went to my local dealer JL dealer and asked the guy working there how much a sealed box for 2 12W6v2s would be.  He said first of all I recommend you use a ported box because it is more efficient, louder, has better sound quality, and has more bass extention.  I understand that a ported box requires less power and has more SPL, but doesn't a sealed box have better SQ?  And I thought that ported boxes didn't extend the frequency of a sub.  Am I right or was that guy really telling the truth?That's my opinion. Take it, leave it, or correct me.

Actually thats wrong, a ported box can be made to sound better than a sealed box, it all depends on the woofer and box design.  Once you figure out how to build ported box's proper with the correct specs, you will never want to go back to sealed.2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.

But then why in SQ comps do they use sealed boxes?That's my opinion. Take it, leave it, or correct me.

Because vented enclosures are HUGE, compared to a sealed enclosure for an equivalent low frequency cut-off. Really, this is about it, next to the previously mentioned difficulty in building one correctly.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

These new slot ported boxes are hard to beat for spl if u set them up right making sure u use a sub bass filter and all, but as for sound quality i believe you will never beat a  well built sealed box.  I personally have never felt a ported box hit  a lower note than a sealed box .(try hitting 10 to 12hz in a ported box) if u have let me know i would love to see box plans so i can experiment.rottenbellys 05 crew cab colorado.Pioneer dehp 880prs, kenwood excelon in all 4 doors.

personally i think a well made ported box built and designed well and cutom 4 these subs are the best way to go--sometimes this means a huge box though

if you have heard a box hit 10-12hz id like to know how? our ears are only capable of 20hz - 20khz

You can't hear that low, and he is talking about SQ not SPL, they arn't the same thing.

Sorry for not being technical ! if u have felt one go that low let me know.rottenbellys 05 crew cab colorado.Pioneer dehp 880prs, kenwood excelon in all 4 doors. Bazooka 500 mono Jl 10w3 in coustom center console box.

Couple of interesting observations. If I read correctly JL's 1961 Mini was built with 2  12" W6V2 woofers that have inserts that remove to convert them to either sealed or vented. With all that was said above and the room for vented box why would they offer the sealed set up? Why did the JL retailer say what he did if JL offers sealed and vented box designs on their websight. And Arrow, did he know what amount of space your box could take up? Just curious.There is no such thing as free installation!
