I've seen this a couple times. But I don't truly know what to think about it. There's a few obvious ones, but when I see something previously high end, specifically some BBC speaker I can't seem to find again, I start to wonder.... What's up with that?

Wow!

Keep in mind that times were different back then. Things we take for granted now were pretty foreign back then. Speakers were shaped like shoe boxes and set on the floor. It's hard to even compare them to today's speakers.

They are early KEF monitors made for BBC, later became famous LS3/5a.

I don't think they were fools. The woofer was good to 2khz.

Dispersion control? Radiation enhancement? Compensation for volume of frequencies short enough?

I made a guitar amp with square holes, well speaker cabinet, with ancient alnico drivers, out of plywood without plastic and crap all over it, just some stain and paint only on sides, bottom and top. It sounds amazing for a nearly untreated pair of 10's. The sound in size is 10 times bigger than the fender speaker in the amp I used to power it. I mean it doesn't sound loud, it sounds huge. The fender sounds like a tiny loud thing stuffed in a small space by comparrison.

does this works like a compression?

Another great question! I got no answers though.

All kidding aside,  you are right,  you'd think there must  have been something specific they were trying to accomplish by doing this, whether or not  it succeeded .....    would this have any  strange effect on  sound waves  ?
Sure does look strange

I'll bet someone at KEF would know the history of those speakers.

Reminds me of some garage sale Utah brand speakers I picked up once where both cabinets had the tweeter offset to the same side.

It will load the driver and increase SPL in a given range.

It look a bit similar to band pass enclousure while this one doesn seem to have tune.
Even if the woofer have good dispersion up to 2k, the blocking of the woofer would have killed it.

I like the base though. :lol:

Hey baniels, there are ADS speakers that have the offset to one side and the other speaker is exactly the same with both offset to the same side. I've never understood it but, I can't argue with ADS. Is it possible they do something in the xover to make all work? That's possible but I doubt it. Is it possible that it really doesn't make any difference? Yes but, it just doesn't seem like that would work. But, who I'm I to argue the design!

Anyways.......
