    Hey all. I've been riding with the ICON sealed for some time and want to put it in a ported box. Really not sure how to make sure the design is correct or even how to work WinISD but below is what I've gathered. I was posting on diymobile and got some help and was suggested a ported box, 2.0ft^3 @ 30hz will give the flattest response. Below is a copy paste from the sticky of "making a correct box design thread" Vehicle : 08 Acura TL Location in the vehicle: Trunk Space available (Length x Width x Height): 23x19x14 (Can be wider and deeper than height) Subwoofer make and model: SSA ICON Subwoofer Size: 12" Number of Subwoofers: 1 Type of Port (Kerfed, Slot, Aero, etc.…

    Just made a new box for my 21" dp (the amp I will be running is a sundown 3500, I have (2) 1750 strapped right now about 3000 watts) in a 2000 Ford Taurus. (8.3 cu ft/32hertz) The sub is facing up, with a top on it to direct wave more in the car and stop trunk rattle. The port is firing in the car. (I guess its sort of a 4th order/ported box combo) During the build I wanted to make sure since the port would be firing in the car and the sub facing up with a top on it, to completely seal the front wave from the rear trunk. After the installation, it was loud but noticeably louder with the trunk open. Ok I must have missed sealing something..... I noticed I missed a few spot…

    I've got a 91' honda prelude, and I'm going to try and use as much of the trunk as possible for a pair of 12's, rather Fi BLs or Fi Qs. I'm thinking of firing the woofers up at the trunk lid or against the back of the trunk, and having the port vent through the trunk opening into the cabin of the car. I've heard how horrible sealed boxes sound if pointed through the trunk into the cabin, I'm just curious if the port would create such a horrible effect. I'm building the box to pretty much use all of the little space I have, so there is nowhere else for the port to be free of obstruction. What do you guys think?

    Well i installed it mid june(?), everything has worked great. Whenever i took people, they said my truck smells weird. I never really thought about it, but last weekend i drove a group to the football game (they chose the guy with an 11 mpg truck to drive 1.5 hours there, wtf lol) and took the box out for the ride up. When i put it back in a couple days later, i noticed the smell. I guess i just got used to it, and never noticed. I know it's not my sub, because it can smell funny when i get in it for the first time in a couple days, when nothing has been playing. I really can't describe it, it's a mixture of things. Wood would definitly be one smell, but could it be sili…

    Attempting to fit two 18" drivers (fi bl) in 34" width. Each driver would be mounted to an angled piece of double baffle mdf. I made a simple rendering to give a visual: Width is 34", each angled piece would be 20"x20" and angled at 45degree angle. The distance from edge of box to where the angled pieces meet would be approx 10". enclosure will be ported, most likely with aero ports for the sake of being easy. Has anyone had any experience with a enclosure like this? output wise vs conventional ported enclosures? Does the fact of the drivers being angled towards each other cause any problems, cancellation, etc. any other input? thank you

    I'm working on a home theater sub. It'll be an aa avalanche 18 in an 21 cu ft llt tuned to 15 hz. I'm trying to figure out how to cut the complicated bracing in this box design. So I was thinking if I got someone to CNC the bracing I can cut the rest of the boards and will have a much easier build. Any suggestions are appreciated. Here is a link. And some pics of the design. I have the google sketchup file, and was wondering if it would be able to make templates of each piece and print them on a plotter. Then I'd cut them to size with a table saw and cut them out with a jig saw. Link to build post

I mean I know the guys at NM&V will put on their shows, I am sure that Ultimate Edge will do their shows again next season, I know that peteyglad and myself will be doing shows in conjunction with Happy Ear nest year. Just wondering if anyone was doing the winter shows again.

    Right now I have a 2.2cubes @ 32hz with 34.50sq.in. of port area with 1100rms for my daily driver. I want to build a pure spl box and a pure sq box before the winter comes. I have 34inches in width and 13inches in hieght. I need to know the tunning, port area, and cubes for each enclosure. I heard spl enclosures should be small and have alot of port area. I'm not sure what kind of boxes I should build so i'd figure i'd ask here since noone knows the icon better than you guys, Thankz.

    I have been messing around with WINISD for the past day or so. Trying to model my 12" Zcons and follow what these graphs are telling me. 1. When I enter the parameters using the autofill for some of them my graph peaks at around 100hz even though my box tuning is much lower. Why is this?Can someone help this NEWB to understand what I have done in error. 2. Also if I enter the paramters of the web site it gives me error messages saying they are incorrect. If I let it autofill some of them then it will graph. Any explanantion why this is? Thanks in advance.
