SPL & SQ / Fabrication

Shizzzon as always if anyone would llike to chime in feel free. Shizzzon has been such a big help to me I wanted to ask him in particular about something I know I have faith in him for. My Port Love everyones ideas though so again chime away! 4 Shizzzzle I've been trying to send you a message w/ my phone #s and invite to for you and whomever to stay at mine and Kelly's home. For some reason I'm not able to send. In the attempted PM i got carried away w/ the following so I'm just making it a topic so I don't lose it. (computer has been acting up maybe on last leg) This would be the help I need from you for my "big boy" system! My previous favorite enclosure was…

I have 2 Assassin Series 8's I need to know how to make the port and how big. The box I have a pre made it is this http://www.millionbuy.com/hbx8antcm.html its .51 cubic feet any help would be great

i just had my wood cut from lowes (they did a bad job cutting) and i was wonder what size screws should i use to put the together? i dont have a router so what else could i use to cut the hole out for my sub? i have some titebond wood glue and some heavy duty liquid nails here.

So, explorers finally safetied.... Now i am going to start the box build. I plan on installing 2 15's for now, but 4 in total down the road. My question, would it be bad for the subs to oversize the box to leave room to cut in speaker openings down the road? The subs call for roughly 3.5 @ 33-35 hz, if i made the box like 12 cubes tuned to the proper frequency what effect would it have? How does the increased size effect the sound and response of the sub? Will their be any dangers in running a sub in an oversize inclosure for daily driving? Thanks in advance. Chris McDonald

Im really attracted to how loud this sub can get...but ive heard it an have some pretty imprssive SQ...qualities...i know about the BL Q and SSD but those just dont seem like they will get loud enough for me...so...BTL 12s in a big ass sealed box...think it might work?

i was wondering if anyone could help me with some plans for a box, for my 15" its an alpine type-r. i no, not the greatest. but its my 1st sub. the opening on my trunk is about 41" by 18" also i have a picture, if that helps.

Well, i just did some testing with about 30 songs and frequencies from 27-55hz individually with positioning a ported and sealed box around in the hatch to determine what sounds loudest to the ear. I only faced sealed forward, everything else is for ported. This test though is with port and sub on same side. I have a sub up port back box but no sub to fit it, lol Sealed firing forward, right behind rear seat - Basically everything just drops in output. IT all sounds the same, just quieter so that definitely isn't recommended. Fire rear, box against the back seat- the mid range 50-60hz seems to hit hardest by doing this but not by much more than firing directly forward! …

Has anyone used eDead for sound dampening. I know that their subwoofers arent great, is this true with their dampening materials as well? I won't pay the outrageous price for Dynamat, I can't afford to spend $400+ to do my car. I can get eDead for .80 cents per square foot. Even if i had to double it up, it would still be considerably cheaper than Dynamat, Second Skin, etc. What do you guys think?

any one with a 2.2-3.0 cu./ft speaker enclosure for sale. it is needed to house a single 12" bl tuned to 32 hz. o fit in trunk of 2006 ford focus zx4. also if no on that then i need a box for two 12's for trunk of same car with same speakers 12" bl fi loaded.......G

alright calm down.. i know the SQ guys are all worked up with sand in thair clams right about now.... i want better sound in my car.. i have some highs and mids but not enough.. i wanna get a cleaner sound. i have 2 bl 15's on a saz 3000d. and then i have 2 sets of 5x7 alpine typr R comps in the doors and in the rear deck. it sounds good at mid to low volume, but when i turn it up to higher volumes the tweeters are steal sounding and the word are ran over a bit by the subs.. its not THAT bad.. if you watch some of my vids you can see that some songs are better then others ...... some sound good.. and then other songs are just blah... i know 5x7s are junk..…

I am getting AA Assassin Series 12"D4 and I want to make a box for them in my tech class. My goal is to make a transmission type box. I am just not sure what you need to do it right. Like how to tune how big you need to make the vent. I want to make the box about 4-5 ft. If anyone can help me that would be great.

O just for giggles i built a lil oh 3cu tuned to 34hz box. . threw it in teh car hooked it up and it gets loud about as loud as my sealed 2 sub box.. But the thing i hate hate hate is that, it only does this at the higher hz's. Like low low bass plays but it doesn't rattle anything ect ect... I think my 18's had me spoiled though and i could just be being biased, lol So to compensate for the lows what would be a better tuning for my needs..28? or should i just go back to 18's

I like to think up things i haven't never seen done so let's get some opinions in here because i wanna see what people think how this would work - I don't feel like drawing a pic so i'm going to rely on your visualizations to see this box in your head. Let's take a 12" sub. Let's put it in a ported box at 2.5 cuft. Tuning... thats the interesting part. Ok, so build a box with 5 walls, not 6, 5. Leave the rear wall completely off. Now, let's say for quick number crunching, the box is as follows - (all external) 16" wide x 16" tall x 16" deep with no rear wall. Now, let's build another box with no sub cut out, again with 5 walls, not 6. Dimensions for this box is as foll…

I have a weird question; I plan on attempting to build some Kick panels. I have some Fiberglass and Kevlar material that might work. But I want your opinion. All this material is about .015 -.035 thick per layer, yeah it would take a lot of layers. This is a Spun-lace polyester material, Its 4

Are 45*s needed with in boxes that use PVC tubing as ports?

So would someone who has mastered this process please help this newbe who just wants to have some good sounds to go along with these badass subs, Or even beter someone who has a solara and a simular setup. I would like to use the area under the rear deck for the encloser and using …

I've got quite a lot going on right now if you cant tell, I've got a client's SQ truck and my personal SPL build going at the same time. I've got some great info from you guys on the SQ build so lets try some on my SPL build. Last year we took state records in USACi in Stock 1801-3001, since then we've been addicted to going bigger and louder. We want to be able to still play music so, no pure tones/burp set up. We've got the durango ripped to down to having nothing but a dash, being completely deadened up. The idea sits at building a wall behind the B pillars for 4 18" BTLs. Haven't decided on what to do to power them yet. We have more than enough room to give them all…

I found a sweet deal I just picked up a killer old school soundstream Rubicon 1002. The blue one. It does 250x2@4 underrated, and 1000x1 at 4 ohm and 2. Will be PLENTY of power for the old front stage. And just a all around sweet amp And I've seen them sell for $250+. I got it for $85... nice...

Are 45*s needed with in boxes that use PVC tubing as ports? Also I designed my box using Win ISD and was told to make the box roughly 2.0 @36hz and use 10" of 4" pvc. Now does WIN ISD take in to account for the space taken up by the PVC or do I have to make the box larger?

I was wondering how to build a ported box for 2 18" btl loaded each one in its own chamber for a 03 Yukon and how to tune it between 30 and 35 Hz. I'm looking get some serious bass. What are some dimensions I can use with the speakers facing up? I will be running them on two saz-3000d. Hello again I'm looking for spl in my 03 yukon. I am looking at running 2 Fi Btl 18" on 2 Saz-3000D amps in this amount of space. H 21" W 46.5 D 22-28". So what do you think? I need help with the box and port dimensions. Once I have an idea I will start the building. I need all the help I can get. Thanks

Alright, I want to switch to Aeros from my slot port to give my subs some more airpsace (2 15s with 5.5cubes is a little small for me).. anyways could anyone help me out here, I know how to design a slot port but not a aero port. How many would I need to get proper port area and the length for say 31-32hz? Box is 38.25wx16hx24.5d

I have 2 sd1v2 10" running on a 1000d. I like the sd1v2s and all but want a little more. Anyone experienced Kicker CVTs. If so will they hit harder than these sundowns? The sd1v2s are sq's, are the CVT's straight SPLs?

so my RL-i 10 has arrived, now i'm waiting on the amp. my 1st question is this. would putting the driver on the back side of the truck box be a bad thing? i know to allow for excursion clearance, but it would still be pretty close to the back wall of the cab (regular cab ranger btw). would there be some adverse effects from the air the sub is pushing not escaping away from the sub fast enough? here is a crude 1 minute drawing. i was thinking if it would be alright to face backwards; i would extend the sides of the box to act as a separator between the box and cab. i've seen boxes like this before, but they were facing the front to give separation from the seat. this n…

ok, i'm gonna risk one hell of a flamming here and ask you guys. i was nomeened R-tard of the month on CA.com for saying this so chances are it's gonna happen here too, but what the hell K my question is can you guys hear the difference between a 4 ohm and 1 ohm load? now im not talking about sitting in someone else's car and knowing it, but if you have a 2x2 sub and wiring it to 1 and 4 ohm load. i have tried it with a two different amps(a 2 channel in 2 ohm bridge) and my current RF bd 1000.1. although on a 1 ohm load and lower it ponds like a bastard it just sounds too off, sort of muddy... this all applies if the amp is stable on those loads of course just curious...
