Giyas tipped up in the highs

[JackD201]

..........More optimal speaker placement closer to the front and side walls than previous speakers.

Giyas load the room quite differently with dual ~8.5" side firing woofers versus the Ushers with dual 11" front firing woofers. Still working to further optimize.

There ya go. Congratulations.

First thing to try is what the manufacturer is suggesting given the apparently unconventional design.

If that doesn't yield improvement keep in mind that treble perception is linked to bass - if bass is weak, treble will dominate and sound bright and if the bass is too much then treble sounds dead, all with no change to treble output. It's all a part of the whole.

The other thing to consider is that we tweak systems, not components. Given that, you might have tweaked performance to push up treble with your earlier speakers to get the sound you wanted which is causing you issues with a more neutral speaker. Assuming components are not the issue, try removing all tweaks to your system and starting from that baseline. I've found that many tweaks I have made in earlier configurations have been counterproductive as my system performance has increased.

Understood and thanks. I've actually found through experience that more so than with bass, if the mid is "weak" or less prominent, then the highs sound more prominent (opposite is also true). The bass commonly has more of an effect on the mids or more specifically mid - bass depending on its output.

Also, I dont have many tweaks in the chain and my system components are, if anything more forgiving and on the warmer side (Wells amp, Purity tube preamp, Aqua DAC).

In addition, I have measured the Vivids on and off axis, toe in, and straight ahead (no toe - in). There is absolutely no high frequency roll - off with the Vivids and as such, toe - in exacerbates the highs. The result is - not much toe - in is preferable which is likely why the vast majority of demos I've seen have them with very little to no toe - in. It's also what's recommended by dealers. The G1 likely doesn't have this issue with the tweeter much higher than the average listening chair. As I understand it, this is a design choice.

All that said, there are ways to mitigate it individually or a combination of - 1) raising the speaker 2) no toe - in (described earlier) 3) carefully applied DSP 4) rake angle (rake back aiming the speaker upwards). Each has its pros and cons and as everything in audio it's all a series of compromises. Thanks again for the input.

All of those solutions have non-desirable side-effects. The purist way would be to reduce the level of the tweeter in the crossover. No side-effects.

Not necessarily, although I would agree the optimal way would be to attenuate the tweeter but not across its full designated frequency band, you'd want a roll off at <8Khz.
