Hi Folks, Just a few photos of the home theatre speakers I have built for my new listening room in my new house. The baffles with sand loaded frame tubes are made from gloss black high density MDF. They sound awesome! I realised that a bigger speaker could equal a bigger sound stage, but I...

Hi Guys, You are all welcome to copy my humble designs. If you like some of my ideas, I have simple diagrams and measurements you can copy or use ....no problem. They are not fancy but they seem to work. To make the 10'' co-axial's look and sound better in my original versions, the top white...

Hi Guy's, I'm looking for a subwoofer or bass driver to be used in an open baffle. I have a pair of Audio Nirvana 15'' coaxials, which i have planned to use in an open baffle. I've briefly tested them and they roll off very quick below 500hz. I have an eq, but i'd rather only use it to tame...

I often get ideas for projects I don't have the time or space for. Anyhoo I noticed these Foster wide bandwidth drivers on sale at Madisound and I got to thinking. At $3 each and with a Qts of 1(ish) these could make some cheap and easy line arrays. You could buy 32 of these for about $100...

Well, with a lot of testing, experimenting, hair pulling, more testing, and crossover design, I finally came up with the design for the new OB HT. I came to a few conclusions during my testing: 1: OB's do not like a horizontal baffle, period. In order to get enough U baffling to support the...

Hey all, Just wanted to update you all on my center channel build. For reference, it's a 3 way design using Dayton RS 8" woofers, HiVi B3N mids, and a BG Neo3PDR tweeter with an open back. Crossover points are currently 500 Hz (2nd L-R), and 3kHz (4th L-R) on a 12" tall baffle with wings of 4"...

Since the driver (and problem) is close to IB, I figured I'd post here: I have an Exodus Audio 15" driver that was a closeout, supposedly good for OB/IB use. 27mm Xmax, great power handling. Right now the VC's are in parallel for 4 Ohm load and driven by an NHT 400W amp (Class G or H I think...

New OB plan I have a new concept for open baffle bookshelf speakers using what I've learned with (and since) my 6.5" open baffle speakers. Here is a list of the things I've learned / opinions I've build on this topic. 1. You can't have small OBs without some sort of bass augmentation. The...

So, after reading the OB thread that 'Bob from St Louis' started I decided to make my own OB speakers. Since I also wanted to learn how to make a crossover myself I opted not to go with any kits or pre-made plans. So, striking out with Unibox, FRD Crossover designer and some forum advice (all...
