Maybe not dynamic range, but what is "depth" in the context of audio?

Depth: The amount the sound seems to eminate from behind the speakers
therefore giving a much more space perspective sound which gives a good
feeling of distance & out of the box experience.
This is not to say that anything that should have a specific point in place
is destroyed by depth.
Any sound that breaks away from appearing from a speaker sounds more
enjoyable to me.


Neutrality: Where a sound is reproduced as accurately as possible without
emphasis of any frequency.
In other words as life like as possible.

The two statements are not synonymous. Lack of emphasis of any frequency
means a flat frequency response, with no sharp peaks or troughs,
especially peaks. "As life like as possible" implies not only a flat
response, but also low distortion and accurate dispersion characteristics
which, when the room acoustics are included, result in an accurate
representation of the recorded event. The closest approach to the original
sound anyone?

That's why it's life like as POSSIBLE. Cheaper gear cannot benefit from all
good measurements but can stab at mimmicking them.
The closest approach to the original sound is much more dependant on source
quality + recordings therefore is not quite the same.

Bass weight: A stronger representation of the lows as if it were a larger
speaker.

How does this differ from extention?


Extention implies that a frequency goes lower but clearly unless the
crossover is designed to allow this it does not.

This is primarily a function of the room, together with the dispersion
characteristics of the loudspeakers.

Crumbs I agree :-)

I doubt it. Active crossovers, especially DSP derived, are the best way of
achieving accurate results. (or screwing things up royally!)

Going active is more of a dream & has been for many a year, it's a expensive
route to take & requires lots of shelf space. This was not my intention at
all. If it proves a pointless exercise in rebuilding the crossovers then I
probably won't do anything at all, apart from putting a improved tweeter in
& amending the crossover circutry to complent (not my designing mind you!).


No, I don't think so unless you can measure the actual performance of each
drive unit individually, then design the crossover accordingly. If you're
going to that sort of effort, an active crossover would be a lot less
trouble.


People have done this whom in the know so it would be just a case of buying
& fitting although not with my actual speakers!
