 Aslo see the Maverick 2's, or Maverick 2C

DESCRIPTION: This loudspeaker is designed to match the timbre and tonal qualities of the Maveric 2's, but also have better dispersion than the Maverick 2's or the Maverick 2C so that it can be used as a center channel speaker for a front projection theater.

My system is comprised of the Maverick 2 main speakers, a Maverick 2C center channel speaker and Radio Shack in-wall speakers for my surrounds. It sounds good in our condominium but my wife and I were having a new house built with a room that was going to be for a dedicated theater, so I figured I needed to make two more speakers.  We are going to use a ceiling mounted projector so shielding is not a requirement.  I decided that the best solution to speaker placement would be to take my Maverick 2C and make a second one and use those for the rear speakers and to make a new center channel speaker.  One that would go a little lower than the current center channel and be a bit larger.  I had figured that I could make one that would fit inside the equipment rack that I was going to build to fit below the wall mounted screen and be oriented vertically, so I decided on the popular MTM style layout to get the best dispersion possible.

After looking for a while, I found the Vance Dickason kit speaker called the Audax A652 (also see the Secrets of Home Theater and High Fidelity review).  It uses two of the same HM170C0 driver that I chose, but with an Audax tweeter in a D'Apollito configuration.  This design is meant to have an F3 of 53 hz and an output of 105db.  I read the reviews and looked at the dimensions that they recommend and decided that it would be a good fit, so I called Madisound and asked that they come up with a crossover for the A652 but with the tweeter being the Vifa D25AG-35 not the Audax model.

I called Madisound and ordered the drivers and had them do the Leap crossover design, using the same crossover components as they did for the Maverick 2's. (Leap predictions)

After getting the drivers and crossovers, I measured the flanges for the drivers so that I could have a friend machine some templates for cutting the recesses in the front cabinet panel so the drivers could be mounted flush.  At this point I have made the templates twice and for some reason, I threw them away each time when I was done making the speakers.  Theses are going to be machined in a machine shop and I don't plan on throwing these away.

I took the simple drawing for the A652 and translated it into a model using Pro-Engineer at work and made all the piece-part drawings as well.  I had to do some modification to the measurements so that the driver distances center-to-center would be the same as the other speakers and so that the cabinet fit properly into my equipment rack.  I decided to make my cabinet deeper, narrower and shorter than the Vance Dickason design so that I would have the flexibility in my rack design, and I have lots of depth to work with anyway since the rack has to be deep enough for my components. I also wanted to make sure that the volume was the same on my drawings and the kit drawings.

For the construction, I used the same technique as I had on the Maverick 2's so that everything was the same styling. By using the ¾-inch thick Oak plywood, the cabinet was very stiff and has very little resonance to it. I stained and finished the cabinet to match and mounted all the components.

About Scott Vonhof:  I have a degree in Electro-Mechanical Design, and have been interested in speaker design for about ten years now. I create my designs using Pro-Engineer software, a solids-modeling package that gives me the ability to run interference checks. I do all my own woodworking, and while I am not an expert, I find it to be a very enjoyable hobby.
