A couple of items for EPOS ES11 and ES14 owners:
ES14 (friend's speakers) - I've recently changed the bi-polar
capacitor in the tweeter crossover for a polypropylene type.
This resulted in a clearer treble that is beautifully
integrated with the clear mid-range. Very explicit, clear mid
and treble now.
Played with removing the foam bung from the port and also tried
cutting the bung so only one third of it was present. The bung
gave very tuneful bass, but very little of it. No bung gave a
bood spectral balance but the bass wasn't as tuneful, not bad
but not up to the quality of the mid and treble. Simple
trade-off of quality vs quanity though with the bung in female
vocals were more expressive or open.
ES11 - Mordaunt-Short are sending me a foam bung from their
series 5 speakers. Some dealers have been using one bung cut
in half to reduce and tighten the bass. I get loads of bass,
so I thought I try this. Only ordered the bung today, I'll
report back when I've tried this. Anyone one out there tried
this already?

I tried a simiilar trick with my old Castle Kendals, but in the end�� I
settled for movving them further from the back wall. Not a domestically
acceptable solution, which was why they were replaced with Kans against
the wall.
I seem to remember someone doing something similar back in the 80's
with Meridian speakers, tuning them to the room. The article was in of
the Haymarket Linn/Naim fanzines of the day.
This person filled the port with drinking straws, which effectively
reduced its cross-sectional area. Using foam slowed the bass down, but
without it the bass was overblown. The straws reduced the level but not
the speed.

| 398.2 | Matched pairs - unmatched components? | HLDE01::KOOI_J | Mon Nov 21 1994 10:06 | 7 | |
Even though this note was posted ages ago:
re 0.: since the ES14 (as well as the ES11, I would guess) are shipped
as matched pairs with the same serial number, aren't you losing this
aspect by buying two capacitors with ??% tolerance?
