Last evening, I had a chance to sit down and take some measurements of my Dharman sub. I was curious to see how it would compare with my DIY Tempest. Below are the numbers. I took these using a tone generator program output from my laptop. The SPL meter was tripod mounted 2 meters from the sub...

I, like many of you in this section, have finished a basement for use as my home theater / entertainment area. Recently, we have a contractor doing a little job on the back of our house that involves adding a trussed roof over part of our deck. Because of this he removed a section of the...

Another post got me to thinking that a lot of would be DIYers may have no idea the minimum list of tools that they either need to own or have access to. I thought I would start a list with some estimated costs and see if we can come up with a usable index. If we assume that this is for a...

I finally had a chance over the weekend to do some semi-serious measurements of the sub I built. I connected my multimeter and set the drive level at 3.02 volts @ 60hz. I wanted to get close to the 2.86 that is normally used. I could have fiddled with the sub amp and set it even closer but...

Last night I got everything finished up. Debbie and I carried the new sub into the room and placed it in the front right corner where the old sub used to be. I had been temporarily using the tempest in a small sealed box that was pretty flimsy. That said, the Tempest was impressive compared...

As always, the more I learn about building speakers the more I realize I don't know. I am building an Adire alignment vented Tempest enclosure. I received the two 3" flared ports via UPS yesterday. Included in the box was the port instruction sheet that included the formula for calculating port...

Looks like several people got a new SPL meter for Christmas. I sat down with Excel and the standard correction chart and filled in all of the values from 10 to 100 HZ in 1 Hz. steps using the growth function in the software. If anyone is interested drop me an email and I'll send it to you.:)

I was on the ACI web site earlier and could no longer find the "kits" area. Have they moved out of the DIY market? Please tell me no....

As I have been working with VE to improve my TV picture quality I have also decided to solve (as best I can) my cable picture problems. My main set downstairs is closest to the main cable landing in the house. I ran the cables for it myself when we finished the basement. I used RG6 coax. The...

I recently got the Video Essentials disc. Over the weekend I spent a couple of hours making the adjustments. Overall the main changes were to lower the brightness and contrast levels. I already had the sharpness off and the color was pretty close as well. Now, on DVD I am getting used to the...
