EDIT: The miniDSP products look too complex for me right now. I'm just learning about all this stuff. The Antimode 8033 is really simple to use.
The Velodyne offers four levels of prompted setup and a very clearly written step by step manual:
1st is the Place & Play and only suggests doing a Crawl Test to optimize placement.
2nd is the Self-EQ requires connecting the microphone and pressing the automatic program button which is essentially what the Antimode requires except there are no extra cables to connect or to locate and power another component.
3rd is the Auto-EQ requires the microphone and the Sweep Tone CD be played during the program running. This very simple procedure that adjusts all the parameters in 15 minutes. After this step you may choose to investigate step four.
4th is the Manual-EQ which requires the completion of Auto-EQ and connection to a TV or a Windows Setup Program. This program will display your main speakers in room frequency response from 200Hz and the response of the subwoofer. Its also the program that allows you to customize the six remote control presets. This is one of those things were the first time you do it takes a few minutes and after that its a breeze.
The JL Audio ARO procedure requires some manual adjustments using a recording with "deep bass content" and having and assistant adjust Polarity and Phase as you listen before Applying Automatic Room Optimization (ARO) as you follow a procedure.
Both 10" JLAudio F series and Velodyne DD Plus may be the most capable subwoofers for their small size.
