Altec Lansing 251 - How to open?

[FatRakoon]

I got an old AL251 setup in my attic.

Many years ago, I was going to add a tweeter to them, but I did not want to wreck them.

They still sound fairly good even though they are old as the hills, and the other day, I was helping my mate out and I dug these things out and sure enough they sound great, but are lacking just that little bit extra, so, long one cut short, what I did, was switch them to 2 Channel, so the surrounds are playing the same as the mains, and, instead of plugging the surrounds into it, I simply quickly plopped a pair of car tweeters onto them instead, and they sounded great.

Fair play!

Anyway, we would really like to have all 5 speakers working rather than cheating like that, and so I wanted to open the boxes up.

But I dont want to wreck them either.

So, has anyone done it? How can I do it?

Thanks if you can help.

Yeah, glad you added that.

Like I said, adding a tweeter makes them a load better... In fact, even though they are well old and have more than served their puyrpose, they are simply better than a lot of setups I have come across for a lot more money, and they would be a great addition for my mates needs.

They would be a seriouslly decent setup if we add a couple of tweeters and yes, going the route of simply adding the tweeter to the BACK LEFT/RIGHT instead of the surround speakers and setting it to 2 Channel instead of 5.1 does indeed give us a really nice warm sound, but I would much prefer to get access to the speakers and do it for all 5 satellites... Well, I will do 4 actually cos Im not really bothered with the center.

The controls are also in the right speaker, and I had given it some thoughts on moving them and making a seperate control box, but in order to do that, what I will do, is use the Center speaker as the right, and buy a seperate but similar speaker for the center.

Oops,. Im waffling.
