speakers for classical music

Harbeth C7ESIII or the Super HL5

Shadorne, thanks for you links and comments. I read it and just didn't think a further comment was needed. Now you've prompted me to ask:

How long is the typical musical peak? If I'm listening at 87dB on average and I have peaks of 105dB, which I have observed and note seem appropriate for the music, if it takes a few seconds for compression to begin, will I experience it often, if ever, in music listening???

BTW, I play electric guitar, so I've actually purposely compressed guitar alnico drivers to get a certain tone quality only available from a compressed speaker (or a good speaker emulator). So, I understand the concept pretty clearly. I'm only wondering how much of a real world factor it is with high quality, high fidelity speakers.

Also, the compression shown on the graphs was actually very small in comparison to the in-room EQ variations of the speakers shown. I'm wondering how much we'll hear those fractional dB losses when taken with all the other interactions.

Don't take this as anti-horn. I plan to investigate Audiokenesis at RMAF, as well as other high efficiency speaker designs. I'm just trying to understand some of the real world implications.

Hi Atmasphere, you said, "This recording puts most speaker/amp combinations right flat on their face nearly right away, if you are unwilling to change the volume as it plays.'

Could you explaine to me what you mean by this. Are you saying you need to turn up/down the volume for this recording due to its dynamics within the recording?

One volume for all!

I'm only wondering how much of a real world factor it is with high quality, high fidelity speakers.

On compressed pop/rock and especially the more modern stuff on CD; Green Day/Red Hot Chilli's/Metallica/Artic Monkeys/Kooks/most remasters and thousands of others - not an issue at all - as the music is already compressed crap anyway!!!

On old school dynamic recordings - classical, Mahler, Shostakovich or great jazz recordings of big band and Sheffield Labs/Chesky/XRCD type stuff it is a HUGE issue. The life of the music is robbed by compression. After a few seconds at the start of the track you are already hearing compression.

Remember at 87 db if you have a large room then your speakers may be at an average of 95 db - already the "average" music at that level is starting to be compressed - so naturally the peaks or what immediately follows them will be even more compressed and worse even "modulated" by the rapid cooling and heating of the voice coil from percussion elements. This is why piano rarely sounds realistic and often sounds like a recording.

Analogy: Think of the voice coil as being like the thin resitive wire in a light bulb...how fast does that get hot - what do you think the heat and momentarily increased resistance does to the transient behaviour and timbre of sounds - well it modifes it significantly!!

It is easy to hear - the first few seconds of a loud passage will sound crisp detailed and clear and then it will rapidly start to sound dull. For example Michael Jackson Bille Jean - the opening will be clear and punchy and crystal clear (like a shotgun) and then it will soon become dull and loose its edge on most speakers.

Shadorne, I'm not hearing that. I DO sit near-field due to my room shape and the furniture layout, so maybe I'm not compressing my drivers much even with an 87dB avg at the listening position.

This weekend I'll torture myself for a while to see if I can simulate it in my system.
