Ported vs Sealed

Tuning isnt the only thing that affects group delay.

The side of the box has a large affect on group dealy. Actually, the size of the box is more important on the ammount of group delay than the tuning. Tuning has more of an affect on where you have the most delay.

So to correct you, low group delay comes from correct tunning and size of enclosure.

I have had both sealed/ported systems, and have friends that have had both. I will NEVER go back to ported. It just doesnt sound as good to me. Ported boxes tend to be boomier and have long, drawn out bass notes. Sealed sounds much more accurate.

true, vented enclosures have more of a tendency to sound like that, but if the enclosure is done right, and its tuned somewhat low (28-34Hz), then you can make it have great SQ, and for daily drivers, many won't be able to tell the difference between ported and sealed, other than the output gains you get from going ported.

keep the box small-mid sized and the tuning low and you will LOVE it.

The enclsoure/sub will only play what signal was given to it.

Boomy? Yes if designed to be so, using poor/SPL drivers, or improperly built.

Making notes longer? Wont do that.

Since box size is an integral part of the correct tuning for the sub (wrong size box with the optimal tuning will still be shit) I stand by my statement as written //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif.

Larger boxes = more efficent with poorer group delay. Not all subs can reach maximum mechanical ability with in their thermal limits in the size enlosure required to have optimal group delay.

Going TOO small can also cause group delay problems as well.

So, I stand by my statement as written.

IB has excellent phase characteristics, //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

I wonder why that is?

I geuss I should have put a //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif by the second one and better clarified the first.

Getting max mechanical ability from a sub has nothing to do with fidelity or sound quality making this a moot point. The optimal box in regards to response accuracy is not going to be the most efficient or loudest but it will sound the best thus being the correct box in both size and tuning, which go hand in hand from the standpoint of a correct box, which is what we are discussing. We are not talking about the loudest, we are talking about the best sounding. In a sealed box many subs reach their mechanical limits well before their thermal limits. Does that make them the wrong box from an SQ standpoint? I think not. You are drawing conclusions based on facts outside the relevance of scope of the discussion.

Going TOO small can also cause group delay problems as well.

Again the box is wrong so you prove my point.

Your point was nothing but a petty argument in the first place.

what would you guys put in a trunk were the gas tank is right behind the seat.(sealed trunk)i have my 15s in a prefabed slot ported box and it sounds weird.its like loud but not...
