Where does it say that I have to adhere to modern standards?

That depends what's most important to you: sentimentality or sound
quality. I'm not being snide, it's a choice you get to make and one
that I can't criticize.

A bit of both. I've had my Kefs for years (20+) and I like their overall
sound. The B139s are generally held in good regard, and sounded very good
when I heard them in the Linns, and that would seem to be an indication of
their potential. I'm not interested in sound quality to the extent of
striving for some abstract notion of perfection.


I 'eard
'em in the Linns and they sounded better than my room can do justice
to, so why should I want to go even better?

Ah, a rare audophile whose stereo sounds good enough.

I don't own Linns, but I do subscribe to the idea of staying within sensible
limits in the diminishing returns game.


Name a driver, and enclosure design/volume, that you recommend
instead.

These guys can tell you where to buy JL Audio products in the UK:

Here's the relevant part of the JL Audio web site:

Thanks. I'll have a look.


If I did that, there'd be big holes in my present speakers.

I was referring to the new subwoofer.

I was referring to the B139s that are in the existing speakers. I'll
clarify: I have two pairs of B139s, one pair in the existing speakers, and a
spare pair. The plan is to experiment with a new bass enclosure without
impacting the existing boxes. That way, if it doesn't work out, I can go
back to the stuff I've used for 20-odd years without sacrifice. So, I take
the spare B139s and build an isobaric cab to try it out. If I like it, I
build a pair of small mid/top cabs and a second isobarik using the drivers
from the existing speakers.


Looks like I'll have to scupper the Nautilus copies built out of
plywood and car body filler, then...

I was referring to my transmission line fantasies.
