SPL & SQ / Fabrication

hey guys i need some help figuring this out.. i have a box with a slotted port.. the port will be 15.5 tall and 4.5 wide the question i have is how deep does it need to be? i want the box tuned to 38 hz the dimensions are 17x30x25.5 (HxWxD) for a total of 5 cu ft im waiting for this i have all of the box cut and ready to be put together other than the port.. btw this is for a mach 5 spl-15 i'll get pics of everything when im done too

Im looking for a nice 1.7-1.5 cu ft sealed box for my 12" Xcon. It willl be powered by my SAZ-1500d. Any ideas for some nice sealed boxes on the internet?

OK i need to run through and make a check with yall to see if my demisions are rgith for this box and its ports ok the box has 4.6 cuft and it will have 2 re sx 12's each displaces .16 cuft and a port that displaces .24 cuft so total displacement = .56cuft which gives the box roughly 4 cuft so i have the port 15w2H14L = 33hz does this sound ok

If I hsve aeroports half internal half external does the volume of the external portion of the port count towards the internal volume of my box? Also would the surface area of the portion of the port within the box divided by 1728 by the ports displacement? Thanks in advance!

Im starting my build in about a week or so and i narrowed my design down to two options. The first option is to have the sub up firing at the rear deck with a kerfed port(s) firing back or sub up firing at the trunk lid with a kerfed port(s) firing into the cabin. after doing a lot of searching i see a lot that like the sub up port back. The reason i chose these two designs is because i cant do both sub and port back or sub back and port to the side. Which option would yield better results? I also its vehicle dependent but my box will have to be build inside the trunk so moving it around is pretty much out the question

just wanted to get some thoughts on bass box 6 pro..is it user friendly for a noob box builder like me and if so does n e one have it avail for a small fee

Hey guys, I know iv posted so many topics about my box but its time for another one. I WAS going rebuild my box for my 18" BTL N2, and make it closer to 7.5 cuft net. Iv been thinking about future upgrades though, and im thinking in the end of it all ill be powering my BTL off of two AB VFL 100.1's strapped (3000wrms). Now with that much power to my subwoofer, would 7.5cuft be a little too big? Iv been talking to one or two people about it and they said it might be a better idea to keep it around 5.5-6 cuft with that much power running to it.

Hi, I finally decided on building my own HT subwoofer (50%HT and 50$ music) and I want to build the best I can of cours at a reasonnable price. I believe I should go with a 18" and planning on using a 7cu3 box. I also love massive bass and I would agree to have a little more power even if I loose a little quality, this is why I am going with a ported box. Now, is the Fi Q 18 would be my best bet? What about the TEAM serie? I don't know yet what frequency I will be using, somewhere arounf 30hz? For the box, here is the 18" shema : http://www.soundsolutionsaudio.com/forum/topic/44520-q-series-cut-sheets/ Thank for your help!

I recently got my system all finished and was wondering if there is an app or something i can download to get an estimate of how many dbs i'm hitting. I know some people that have termlabs but i don't wanna drive an hour for a 5 minute test.

So I have my normal starting bat up front and I'm going to put an additional battery in the rear of the car near the amps. My question is should i run a fuse near the main bat to the 2nd bat as well as in between the second bat and the amp. All in all I don't think an additional fuse would hurt anything and if they power wire ever chaffed through I think I'd be really glad I had a fuse there. any help

So I want to build a false floor in the trunk of my Miata, to cover the amps that are sitting in the recessed well of the trunk. Never having done this before, and not too skilled at woodworking, how do I make a template design that conforms to the outlines of the trunk? I know they say to trace it out on cardboard, but how do you get the cardboard pressed up into all the nooks and corners of the trunk so the tracing is accurate, to trace out a line that shows the exact curve or square of the trunk floor? So the final wood floor basically press fits into the corners and walls of the trunk? My thought is to have a floor that covers the entire trunk, with the section cove…

Hey guys, I'm goin g to try and build a glassed back dash to hold my mids. I was wondering if someone could give me any tips and mainly what I will need to do this. I've heard fleece, resin, and hardener. But which ressin and Hardner should I get? If I use wood to build the base should I use like 1/4 inch mdf or does it matter. Anyway, I wanted to get some of the materials today so anything will help. I'm going to look for a jasper jig so I will be back. Josh

I just had a box built for my 2 icon 12's tuned at 30hz.I had it metered at my local shop.they said it was peaking at 40hz.is this normal?is it cabin gain etc.

Hello , I am building a box with a round port. I'll try to flare the openings to have a nice flare port It will be a 6" port or an 8", I don't know yet ! How far from the box side can I have the port ? How much "room" does it need to play correctly, safely ? I know I can use an elbow, and I will if it's necessary. Thanks in advance for your advices.

alrighhtttyy guys.... i got a tricky build that i need some help with. I'm putting two SPL-15s in the trunk of a 01 chrysler sebring sedan. The subs are going to front firing and im just going to keep the back seats down (when i put them up for people to sit in them i will just cut the subs off). The trunk is pretty flat and the box should be pretty easy to load in from the car with the seats folded down. I have L29 x W34 x H18 to work with, Im guessing both subs will be put in one chamber. Im open to either slot or tube ports, just need help coming up with a design. All of the parameters are here. I appreciate it alot and please help a fellow forumer out =]

I'm going to attempt fiberglassing for the first time. I'm going to make some kick pods for 6.5" Midbass and Softdome Tweets. I've read just about every forum and "How To" I can find so I'm pretty sure I know what I'm in for, but the one thing I haven't been able to find is how much chopped mat do I need to buy. I'm going to order from US Composites and they have 3/4, 1 1/5 and 2 oz chopped mat. Which size is most commonly used and how many yards would be adequate? I'm sure I'll need some extra just incase I do some beginners f*ck ups Thanks, Bob.

I've been tryin to find a set that will owkr well together 2 way active.. I think I've come up with it. It will be run off a old sony mobile ES xm-5046 choices (madisound) mid - either SEAS ca18rnx or L18rnx(aluminum) both 7" tweet - SEAS 1" textile dome 27tffn I believe either of these would blend well and work together in a active 2 way.. What do you think?? or WOuld both mids work or would one choice be better?? Thanks, Joe. P

which way should i do my box design for a btl 18'' with two 6 in aero ports. sub up, aero back?

Who are the reputable box builders hanging out on this site? Going to be needing a box sometime soon.

Hey guys, I have my second Xcon and needing new enclosure but have been debating staying ported or going back to sealed (save cargo space) Anyway, I am first time user of Winisd and not sure if I did this correct so could someone let me know if it looks ok? How do you interpret this graph? To me it looks like ported is the way to go. (I modeled using two 15" Xcons at 1000rms each) Let me know if you need any additional info about my setup...believe my SUV cabin gain peaks @ 49 Hz.

I bet you'd never see me post this M5 haha anyways, ill post what im looking to do and what im working with. its my daily driver, a 2011 ford flex, with the stock Sony system, SYNC, etc. first up, HU. i dont want to replace the stock unit. its a good unit and i dont want to mess with an aftermarket one. theres a guy on the flex forum that runs a JBL MS8 with his stock unit and says its incredible. budget wise, im not going to throw a number, but i will state that i am not going to be paying like 500+ per speaker or anything crazy. this is just a daily driver and even the cheapest of a "sq" setup will sound good to me, as i mainly use pro audio in my other rides. i d…
