Hey guys, so budget is a limiting factory for my build its a 500mm cube I don't mind ported or sealed but need sub 30hz(my mains comfortably get to about 35 before they roll off too steep) I am in the UK so somthing available here would help as I would have to spend on shipping & import duties...

I am trying to 'optimize' the performance of my main speakers by phase aligning the drivers. System is actively crossed as follows. Top end is an Oris horn with Tang Band 8" driver crossed at 204hz using L/R 24db xover, covering 204hz-20kHz. Next is 15" woofer open baffle crossed from...

Hi folks, I have been away for a while but I am back now and ready to begin my second build. For this build, I want to go with a 12" sealed enclosure, for my medium sized bonus room. Basically looking for great sound quality and high output. Will be putting about 800 watts to it. The top...

Hello, After reading for months:nerd:, I have decided to build a sub. At first my thoughts were to build an IB sub. But with some concerns of shaking up the roof structures :scared:, and more so after some modeling in WinISD, decided to go with ported sub (for now). Now, which driver to use? I...

hey~ my room dimension is about 4m*8m. My favorite HT/music is 80:20 I considers that I build 2 subs contains 15" driver and place 2 subs beside the sofar for balance. I hope I can do a seal box,because it is easier than port.:scratch: I have used unibox to calculate box volume. but now I need...

Hi All, I've been floating around for a long time, and also I've built some subwoofers. I'm very impressed with what I've produced so far, but the DIY bug bit me, and I need to ramp it up. Being from South Africa, importing drivers are a tad expensive, but I did find local drivers that has...

Hi everyone, thanks for all your posts on this forum - what a great resource. I'm building a house and planning on an IB sub using 4 x IXL 18.2.2's. Yes, I know this is not the IB forum. Stay with me please! :) While the house is being designed and built (12 months still) I want to put the...

I have never been very good at determining the optimum box size for a given woofer. I used to have a program that would do the calculations but I cant seem to find it (recent computer upgrade) SO... I have 2 questions 1. can some one direct me to a cheep (>free<) program to figure out the...

As I am giving the entire front stage of my small Home Theater a bit of a 'DIY' revamp, I am also hoping to pay a bit of attention to the bottom end at the same time. For this, I am looking for a pair of 6.5" Mid-Woofers or Sub-Woofers to integrate into the system. I prefer a pair both for...

Ok the new theater is started. The subs will be behind false walls and have about 12cf each (two cabinets). I'm torn between 2 Dayton 15" HF's sealed per cabinet or 1 loaded LLT per cab. I'll likely buy the EP4000 either way. I'm open to different ideas though (18 or 21" drivers are expensive!)...

I am looking to build a new sub with more headroom and excursion than my previous sub, adire audio shiva 3 (not x). After playing Avatar on blue ray my old shiva threatend to shoot it's voice coil into next year! making loud clacking sounds. So I think I want a good 15 incher with good x-max and...

Im trying to get the last little bits worked out so I know all my specs and sizes when I go out to buy my MDF today and the last thing I need to figure out to get my box size is the volume of the driver. Im using a CSS Trio 12 and Im having a hard time figuring out the volume it displaces.
