well done Stephen, they are super speakers when they are in tip top condition
they should really be identical mirrors of each other, so you need to know which one to copy, so they end up both right - do you have the proper stands to sit them on as well ??
Thank you.
Yes, I have the correct factory stands. Favored placement so far is on the floor, using the stands with the woofers down, tipped up and in slightly.

I had a pair of RL140's from new and they were identical.
I can't recall the serial numbers but would not be surprised if they went through manufacturing on a batch basis and they then took any two to make a pair. They were certainly boxed separately.
I always rated them very highly, even defending them against the Penta sheep. Especially so when driven by a QUAD 405 amplifier, as B&O did not have an amp to do them justice at the time.
I'm calling that question answered, RL-140's were not mfg.d in mirrored pairs.
Agreed, no surprise at all, especially as they were all identical.
Penta's have flocks, eh? Can't comment further as these RL-140s are my one and only experience w/B&O equipment.
Now for some additional RL-140 observations. The fella I got the tweeter from agreed to my request to send me the enclosure he had pulled the drivers and crossover from for sale on e-bay. It arrived with the grill cloth missing which was cool as the primary reason for obtaining the enclosure was to develop a method to replace said grill cloth and maintain the "Bang & Olufsen" logo on front. Turns out one woofer and the mid were still in it. I can certainly see why the mid was there, are those things epoxied in or what? So this is my first look at the front of the baffle and I noticed two interesting things.
1. The tweeter opening expands into a very nicely contoured horn that looks like a small trumpet. Try that with a piece of plywood or MDF.
2. The mid has its own enclosure, which seems to be a common practice when cone type drivers are used. When I was first assessing my 140's for repair needs, I pulled the back from the mid enclosure to check the surround. Turned out to be rubber that was in good condition (thankfully). I noticed two sets of 4 holes (approx. 5/8" dia.) each on either side of the driver, but couldn't see through them. "Why bother with the holes just to block them off?" thinks I. Turns out the holes, one set slightly below center, the other set slightly above, are covered by a thin piece of coarse felt. A vented enclosure for the mid. I may be showing my newbness here, but I've never seen or heard of such.
This B&O stuff is really quite interesting. I may have to get some more.
joeyboygolf - What is pictured in your avatar? An excellently obvious example of the mirror image, for sure.
