elac fs137 jet and similar designs

hansi · 25th January 2009, 03:20 PM

This question is about speakers being able to produce an illusion of musical instruments being located at exact positions in the room when listening to music. I have heard that designs like elac fs137 jet (which is test-winner in the 1000 Euso-class) may have problems in this respect if the bass/midrange-drivers are separated too much.

Has anyone evaluated this for elac fs137 jet or on similar designs?

How does the mentioned ability depend on the distance between the bass/midrange-drivers?

Hi,

Seems a perfectly soundly(sic) designed 2.5 way.
The MT c/o at 2.5kHz is fine in terms of spacing issues.
The bass to mid 0.5 c/o point has no spacing issues at all.

Thank you sreten,
have you listened to this kind of designs and
found them to produce a precise "image" of
the sound?

Hi,

I've not listened to them in your terms.
A 2.5way should be the same as a 2-way.
140mm driver + small tweeter is close spacing.

To me there is no this "kind" of design, not enough detail.
There is good design and bad design, bad sounds poor.

/sreten.
