Center Channel Project Completed

[jpg]

I finally completed my home theater center channel project and thought I'd show off the finished goods. Recap of earlier thread: Design & build a HT CC that would compliment the sound quality of the Model 19's, and fit aesthetically into my system. Thanks to input from folks on this site, I wound up building a flattened 9844 cabinet. Components are a pair of 414-16Z, 802-8G, 811B, and a N1201-8A crossover. It's an understatement to say that I'm really pleased with way the system turned out!

This thing's pretty heavy, it's built with 13 ply baltic birch and 2x4 internal bracing - I suspended it from the entertainment bridge so the weight wouldn't distort the TV cabinet. Plus, I can pull out the TV for cable hookups without messing with the speaker. It's a rear projection HDTV & the guns are in the bottom, so the speaker magnets don't mess with the picture.

I hope the purists stomachs aren't wretching at the sight of black model 19's in the photo's.... They were trashed pretty bad when I got them & had BBQ grills for woofer protection. They also had custom 240VAC power outlets on the back for speaker terminals. But for $200 who's to complain? Plus the black helps them dissappear when watching a movie in a darkened room. I just picked up a near perfect 2nd pair of 19's and now have the ultimate surround speakers - I promise that I won't be painting those black ;^)

The black M19's have had a full workover; reconed 416's, rebuilt Xovers, deadened & tweaked horns etc, and sound better than any speaker I've ever owned. A big thanks to everyone here for sharing information on all things Altec; many of the ideas that I
adopted in my M19's are things that were contributed at this forum. Thanks! Photo's following....

Very nice, I hope it sounds good to you. Have you build the crossover from the 19 new or changed the parts ?

<font size="2" face="Verdana, Helvetica, sans-serif">This is EXACTLY what I am planning on building and have the components all ready to go. I have Malibus for my front speakers which also have the two 414s but have the 806/811s and a 800hz XO. I realize there may be some dispersion issues due to the mismatched vertical/horizontal platform differences between the fronts and center but that is what fits in my room. Did you use the same volume box and port size as the 9844s?

Thanks.. I built the M19 crossover for the center channel on top of an Altec 1234C crossover chassis and mounted it in the back panel. The L-Pads are bypassed; Replaced the MF with a fixed 10 ohm resistor, and replaced the HF with a fixed 3 ohm resistor. Added a switch that shorts out the 3 ohm resistor to give me 2 levels of HF. Added another switch that reverses polarity of the HF.

This would be great with Malibu's or 9844's... The box is bigger than a 9844 but is lined inside with panels of wavy foam, which decreases the airspace. In essence, it's the same size as a 9844. Listening to just the one speaker with a mono source, you can hear the driver separation if you move to one side or the other. When watching a movie you can't tell the difference. And it's off when listening to music.
