i have a BNIB OZ ME15.4 f/s 180 shipped. awesome SQ sub that will still get up and wang. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

if you want sq, stick to sealed.

Why? You can get every bit of detail from using the right sub in the right ported box. Ported isn't as forgiving and 99% of the people on this forum use grossly mistuned boxes (mostly on purpose), but that doesn't mean that there in an inherent decrease in SQ by going with a ported system.

There are many discussions on this topic on here. It always ends up saying that the infinite frequency response of a sealed box will always have better SQ than a ported box, even though you can make a ported box sound quite good.

The summed freq response of the sealed box combined with the transfre function of the cabin will *usually* yield a flatter measured response (a lot depends on the vehicle and this doesn't account for the low frequency roll off of human hearing or the low frequency masking from road noise in a moving vehicle) but as far as tonality and transient response goes, there is almost no difference between sealed and a properly tuned ported box. There are a lot of variables and you have to get the box right, but to just say that sealed is SQ and ported isn't is ignorant.

yessir!!! i agree 100% //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

there are plenty of great sq subs that can be really loud out there -

re xxx, brahma, idmax, si magnum, fi q, jl 12w7, dd 9500...

i got my 12" idmax and sundown 1500d for just about $700, right fit in your bill

get one that can catch the beat and not so boomy. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Just get a JL 12" w3v2 paired with a JL 500/1 amp. Very great sub! I like them alot! And they are not super expensive either.

I have 3 10" Image Dynamics OEMs for sale in the classifieds. They are at home in small boxes. 1.5 cubes sealed would be more than enough for all three. Feed them 600-1000w at 2 ohms and I think you'll be very happy.

$200 shipped

PM me if you want more info.

Otherwise, I would check out the Polk SR series subs

i cant stress this enough. people give ported boxes a bad rap because they can design one properly, tune one properly, or load one properly. if you are off on volume, port, or the volume and port relationship, you are going to sound like garbage.

a properly built ported box has the potential to sound extremely good. my current box is spot on for the vehicle. i have the most range i have ever had out of many many setups, and it has the most definition and cleanest note shifts i have ever had.

so transfer function isnt in existence with any enclosure. it is the effect or relationship that the car has the with enclosure. much like tuning a ported box at 1/4 wave of the vehicle to yield the best results. it is always present.

the nature of the sealed box with a qtc value of .707 will yield the flattest response. getting the vehicles acoustics right is sometimes a challenge. i see the point that you are getting at and i dont mean to be a jerk about it, but i wanted to add to it. if you wanted to work with the road noise and res freq at a given speed, DSP would most likely be the best solution to get a happy medium.

I disagree. Excluding the "mistuned boxes" for a moment, even in the best built ported boxes, they can sound very good, but they don't sound as good as the best sealed sub systems. That has been my experience and preference. Add back in the "mistuned" boxes and the sound of most ported boxes is unpleasant to me. Not all drivers work best in sealed cabinets, so it's not an absolute rule that all speakers would sound better sealed, but IMO, 99% of sub systems would sound better sealed. How much better is subjective and in some cases insignificant. Most people only car about SPL, so for them ported is better anyway.

To me a very good ported sub sounds like it's sealed. That is rare.

Because ported boxes have a peaked response, rather than a flat[er] response, they may sound great with most uses, but occasionally when playing music that hits' just the right frequency they sound bad and unrealistic. Cabin or room effect usually worsens this effect. Sealed systems have less cabin/room effect, due to flatter response.

I use large ported sub systems everyday in live concert audio, and I can't wait to go home and listen to a sealed sub system. It's a trade off, ported is defineatly louder, but IMO, as a general rule; sealed sounds better.
