I stated ''weird'' meaning it's weird if MD28 is posting a pic of a random setup that did not belong to you. Not sure how you perceived that in a demeaning way towards yourself. No need for your condescending comment. It was not warranted.

Im confused. Why did you post that pic of the Cv speakers when I asked what type of speakers did Werewolf84 have in his system?

I read somewhere there is a general rule of thumb, one pound polyfill per one cubic feet especially for large box that over 3 cubic feet
That's a very vague 'rule', and doesn't take into consideration the purpose of stuffing, which is to get Qtc to a desired figure. The actual answer of how much to use is as much as it takes, or as little as it needs. Measure the finished result, if Qtc/response isn't right add or remove stuffing until you get it right.

WereWolf84,
Looking good! I would put more bracing on the middle of the cabinet as Bill mentioned. I know people make pretty bracing and such but it does not take much if put in the correct spots. The enclosure itself is bracing the corners and especially when using double baffles, the weak points are the middle of the cabinets. I would put 3 braces like pictured above, one in the middle, and two equidistant apart from the middle. So basically if you have a 28 inch long cab I would put the braces at 7 inches, 14 inches, and 21 inches.

That's a very vague 'rule', and doesn't take into consideration the purpose of stuffing, which is to get Qtc to a desired figure. The actual answer of how much to use is as much as it takes, or as little as it needs. Measure the finished result, if Qtc/response isn't right add or remove stuffing until you get it right.
And if you have an impedance analyzer, you can determine (Fb) almost precisely what the Qtc. of the box is apart from the room. 1 pound per is about right...3.5 lbs into a 3.5 cu. ft box is a pretty snug fit.

Since tight and punchy are subjective terms that have a different meaning to everyone you ask I can't say. Generally speaking too high a Qtc can lead to excessive midbass, which most listeners call 'boomy', too low a Qtc can make the midbass sound weak. Modeling the cab in WinISD you can see the changes that box size makes to Qtc and to response.

You obviously don't want the driver's pole vent blocked or anything touching the cone.
10 lbs. my friend...10 lbs. because the QTC is bloody high enough [~.975] for that driver in that size box. Wal-mart should have bags of polyfill and not require any pillows per se, or just take the poly out of the pillow, assuming of course they are not filled with feathers instead!

10 lb should be equivalent to 6 poly pillows, right?

Not sure about pillows. I just buy the fill by the bag. Have bought at Wal-Mart before.

this sub application is somewhat on the ridiculous side. on paper the motor is weak. if your not going to use this sub in an ib application, waste of space and cash. they do look cool though. reminds me of the back to the future scene of the giant speaker lol

Your post is very rude. And you have not heard the sub in question yet you are passing judgement. Everyone of your posts in this thread is either a random joke or a negative comment.

rude or not... i'm looking at the specs. bottom line, the motor is weak. not worth price and a big waste of space. again, they do look cool

and... i dont need to listen to the sub to pass judgement. reading the specs is all you need to know to not buy it. i guarantee i can burn the voice coils in that sub using the recommended 1500 watts. i'll pay for shipping if you send me yours and... if i burn up the sub, i'll give you 2 image dynamics idmax subs. want to?

Guys like you are the reason SI is leaving the HT market. You theorize based on specs, dont buy anything, dont listen to anything, yet immediately pass judgement.

If you dont like the design of the driver that is fine. You are entitled to your opinion. But you dont have to come to another member's build thread to spread negativity.

Swolephile has been feed the driver with 3,500+ watts and it's still survive and going strong rolleyes.gif Nick said put it in 10 cubic feet sealed enclosure is as great as IB application and I trust him, don't tell us you know the driver better the one who design & build it? rolleyes.gif Nick's 18 inch drivers has been sold like hot cakes and well received by many HT enthusiasts/ bass lunatics, even in some AVS members' 4-5 stars ULF score setup

None of the IDmax subs have the output to keep up with my speakers so I will pass on your offer. Thanks.
