Sam, you know that the switch means nothing (the db is a relative measurement not an absolute one) without a full understanding of the XO as well as the freq. resp curves and impedance curves of the loudspeaker. For example the +3b switch (in the 937) could be labelled as 0db and the 0db (in the 937) as -3db and they'd still be correctly labelled.

Much more accurate explanation; would the feedback to the GT5 series have anything to do with this?

Sam any idea why there is a hole in the center of the "time lens" of the larger tweeter in the 937? As discussed on another thread apparently this is true of the 607/507 tweeters too. I cant understand how it would help the dispersion characteristics?

But 937s do sound brighter with +3 db.. so given your view, what should a layman like me understand?

I stand corrected. So the -6dB option is there only in the comps ?

That 937s at 0db are best for listening to Chamkila. If you want more chamak from Chamkila, press the switch in.

Or, to use another bad analogy, one is like the Cheese burst pizza, for which when they ask extra cheese, you say no,
and the other is like the deep dish, to which when they ask extra cheese, you say yes please



* I suck at analogies

Oops sam.
My bad , i confused them with the components ( the 607 and the 608)

Sorry for hijacking this thread but did not feel a reason to open a new one for 1 small question :

Is the 608c brighter or laid back as compared to the 607c?

As per Sam's earlier posts, the 608C is less "brighter" than the 607C.

Dont panic Abhinav, your choice of equipment is good..608 is better because it has options to go much laid-back as in -ve (laid back) side, but since you prefer bright sound.. it'll sound like 607C.. we have to look at +ve side (brighter) only. cheers: All you need to adjust the crossover settings, simple!

No one knows? Come on! we have 10+ gurus on this forum (many of whom have spent more than half their life in audio) and no answer?
