build...

I have never done a speaker build before, but am handy with tools and electronics and I really want something a LOT better than the little 6" 25W HTIB sub that currently "fills in" my bottom end. so... after months of digging around trying to figure out what works best for me I think I have it...

So, I'm hoping to start gathering information for starting my "company". I'll build a nice subwoofer for cheap, make it look nice, and sell it for 150% the build cost (at least). My goal is 120 decibels @ 30 Hz. I know I'm sounding a bit vague, but I'm just brainstorming at the moment. Could I...

Just waiting to get the final measurements for port length and tuning, but got started today anyways: Here's the 46" piece of 16" sonotube as well as a 31" length of 6" PVC for the port: Easy to cut this stuff. Just measure it, mask off the one side as a guide, then use a jig or skil to cut...

Hey all, First time poster here. I have to say that this is a great forum! Lots of GREAT advice and examples to get ideas from! Here is my current project. Basically it is a 7 cu.ft. ported enclosure tuned to 20hz. The net volume is a tad over 6 cu ft. I am currently planning on powering...

I have been reading extensively on the forum and am taking the plunge on a DIY SonoSub. I selected the Dayton RS315HF-4 and a Dayton SA240 plate amp. I have a section of 18" Sonotube and want to use a 36" length for the sub. I have modeled the project in WinISD and wanted to see if I am...

Hi guys, this is my first thread on these forums and I suppose it's only appropriate that I'm asking for help. :) For the past few weeks I've been spending a lot of my time reading the AVS Forums DIY Subwoofer/Speaker forum contemplating building my own subwoofer. Don't ask me why but, from...

Well, this will be my first time posting so if done poorly bear with me. My wife and I got a new place a year or so ago and it became pretty obvious (to me) that our 12" 150W SONY piece of ($125) sub just wasn't up to snuff. When we moved in first up went the wallmount 40" flatscreen and the...

Hey guys, I came across a pair of Dayton RS12HF-4 real cheap a while back...I recently bought a pair of O-audio 300 watt plate amps to with them. Now it's time to build the enclosures and I was just looking to hear what your ideas sound like. I would like to stick with a ported enclosure as...

I'd like to thank NEO-Dan (AVS) for his cutsheet and design and Sherv for the motivation to get this project rolling. Here is the design I used (courtesy of Dan): I had the worker at Lowes cut the sheet into three sections (the two sides off the end, and then down the middle) to make it...
