"more forgiving speakers"

Sometimes a speaker will have a rolled off high end, other times it will not have the resolving detail to show all of the inherent sonic nasties, that lesser audio components tend to have. A forgiving speaker is less apt to show these sonic aberations from the components upstream, or a lesser recording.

'more forgiving' is possibly a nice way to say that the speakers are not very 'revealing' and has a voice of its own to cover other problems in your signal path.

What would you rather have, a system that only sounds great on great recordings (referring here to the sound, not the musical performance) and makes a normal recording unlistenable, or a system that might not reveal the Nth degree of realism on the best recordings, but makes normal recordings sound listenable? If you are familiar with live, unamplified music, you will notice that most audiophile type speaker are skewed towards the high frequencies. This incorrect tonal balance is sometimes mistaken for greater transparency or detail.

Here's an example of more forgiving speakers in my system.

I have a pair of ProAc Tablette 50 Signatures and a pair of Sonus Faber Concertinos. The ProAcs are very revealing in my system. They are what I listen to when I get a new CD and want to hear everything in the recording. The ProAcs are very lifelike and involving, but also expose any weaknesses in my set up. Whether they expose true or imagined detail and flaws, I'm not sure of.

The Concertinos on the other hand, have a softer and rounder presentation. They are a less revealing, a little less detailed and have a distinctly woody voice. Much warmer overall. They are what I listen to when I just want to kick back and relax.

Depending on the recording, these two speakers can sound similar or starkly different. Jumping back between the two highlights any differences. But when I listen to the Sonus Fabers for an extended period I adjust to them, and am no longer aware of the loss of detail.

I hope this helps.
