Altec 846B's

These are the very nice Vals I got from a friend a couple of weeks ago. I pulled the crossovers and installed a board with two sets of connectors so I can bi-amp these like I did with my 846A's with the beat up cabinets.

Everything can be switched back with no damage to the original setup. I may in the future switch the 806 compression drivers out for some 902's which will fit inside the cabinets. The 802's would require cutting a hole in the back of the cabinet and building a cover.

For amplifiers I have a MC-275 powering the 811B horns and a MC-2205 running the 416 woofers. As for listening, the only difference I hear between the A & B models is the B seems to have slightly more bass presence. Some claim they can hear the ports breathing on the B model but so far I haven't heard anything like that.

I'm just thrilled to have cabinets I don't have to cover with pieces of carpet.

Here are some pictures I took as I went along.

Click on the picture and it'll take you to a slideshow. Move your mouse around the bottom right corner of the picture and the forward-stop-backwards buttons will illuminate so you can control the slideshow.

Hi Mike,
I also have a nice pair of 846B's. I bought mine new in 1975. Right now I am powering them with an MX110 and an MC240. They are box stock but I have been considering the 902 up grade myself. I would also need to consider a XO upgrade as well since the original N800's are considered minimal.

I admit I'm ignorant with the technical stuff. I'm just looking for suggestions for a good replacement.

Please keep posting your progress.
Thanks...

After swapping to 802/902, the cheap & easy biamp mod would use the 30923 biampable network for the shelving that will take full advantage of the switch. :)

The reason you don't see a slideshow is that it doesn't work for folks living in the swamp. How have you been Ron? Still racing? You ought to stop in on your way to Madras sometime.

Doesn't work for me either, but this one does where I can view the slideshow: Stereo Equipment :: Bi-amping Altec Valencias. slideshow by Mike_Gibson - Photobucket

Thanks Greg, I wonder why it works for some and not others?

I can't get it because my fire wall is set too high. It seems to want to block
everything except posts by Bfish.

You're welcome! Don't have a clue, I'm not much of a computer geek. All I did was get to your album and try the different links available to see if I could get any of them to work as a slide-show in a new message and when I couldn't, posted the link.

Just tried in I.E. and it didn't work either. :(

I've been ok. Work is nuts. I took a year off after the "bumper stand wheelie". Still scared to drive it!
Nitrous is a bad thing.......

Re: Altec 846B's

I'm too old to even think about driving something like that. I'll stick to my chipped dodge pickup and think it's quick enough. :)
