I never got into the Dx's they arent as relaxed as I prefer.

I have no problem going ported for SQ, its all about the tuning styx (ok, well a lot more but you know what I mean). Hell my 10W6v2 was ported.

 

externally port them. with the aero ports going out of the box instead of in.

 

a ported box tuned designed for SQ is always gonna be pretty big. to big for most people. everyone ends up making comprimises and cuting corners next thing you know that 10 cuft box tuned to 18 Hz ends up being a 3 cuft box tuned to 36hz

 

In which case it's gonna sound sick! 3ft^3 tuned to 36hz is gonna sound pretty damn good to me, and MUCH BETTER than your sealed box with .60ft^3 with a 10" whose response is very peaky...lol. You guys need to listen to more systems before you go on spouting off about how sealed is the be all end all...

 

You need to be more specific because you keep saying this and it won't be true for 90% of the people on this forum. SMALL sealed enclosures DO NOT play lower than properly ported enclosures, and considering that the overwhelming majority of people are running some version of a SCS box with about .6ft^3 per 10" sub, that statement is misleading. Also take into consideration the amount of power that is needed to play low frequencies in a (small) sealed enclosure and you create an expectation that's unrealistic for most.

 

7lug, I was responding to weazel, not to everyone in general. He has a seat lift and 2.2 or so cubes of space with 2 12" W6s. I guarentee you they will play 25 Hz a hell of a lot louder than the ported application he was considering....that was the point of my post.

As for the small SCS boxs, keep in mind that the drivers that fit into these boxes are small displacement 10s that are usually designed for use in a small sealed box. It depends on the particular driver, but say 2 IDQv2 10s are in a small underseat box with .6 each....they will perform fine below 30Hz....I know because I've heard them in this exact situation.

 

anything ported tuned to 36 Hz iz going to be even MORE peaky and way less than flat than my sealed box I designed specifically for my drivers with a perfect .707 Qtc alignment

maybe you need a refresher?

 

I disagree. Its really going to come down to driver selection (Vas, Fs, Qts). But more commonly, that would not be the case. 33Hz would be the highest I would tune for Sq. It would unload starting approx around 25Hz. The bottom 5, I would worry too much about because most of the IASCA/USACi discs I dont remember scraping the bottom 5 Hz that much. Ya, a point may be shaved but I doubt it.

 

I've had ported boxes tuned to mid 30's totally fail to dig into the 20's the problem with sq tuned ported boxes is they need to be pretty big and tuned to the low 20's (if the driver even has a Fs that low)

 

the box i have in mine is 4.5^ft3 for the 2 subs and it digs down pretty deep below 20hz but the power handling is a little limited that low especially without a subsonic on them when they get down to around 15. i have always thought subs sound better in sealed boxes that are a little larger than what the sub calls for rather than a small sealed box. but i only like the deep bass nothing over 45, 50 hz. i have the crossovers on the amps all the way down. scold me if yall want i dont care

 

only way i think you could keep em under your seat is if you got crazy w/ a box and made it flow into a center console for the rear seat or something which would give them a little more air space so you could possibly port them, other than that you gotta take out the seat or get creative

 

Idk, there still is so many variables between the boxes. Ive had boxes dig well in the 1.5ish range and then the same happen (different situation) around 3+cuft.

 

like you said its all driver dependant. most guys still build boxes on the small side

 

Agreed. That is the great and horrid part of this industry.... Too many subtle differences that change everything.
