how make your speker faster

With this description, the only power amp that comes to mind is one that uses bipolar output transistors, instead of mosfet outputs.

I haven't heard your speakers to have an opinion on their sound. But, try toeing them in to align with your ears. Then move them in and out to see if that helps any, and still gives a good sound stage.

Another thing I noticed from viewing their pictures and dimensions, the midrange and tweeters seem high. When you are sitting, you may be too low, and in alignment with the woofers. That can sure cause a problem. Please try this seat height test. Pillows, or whatever will get you there.

Try raising your seat height so your ears are more horizontally even with the midrange and tweeter height. If your ears are at this (midrange tweeter) height instead of the woofers height, I imagine they'd sound more toward what your seeking. They may sound more accurate too.

I don't know if they supplied any info for setting them up. If you tilt them forward to try to get that same alignment, they may be at risk of falling forward. This could be dangerous for people, and ruin your speakers fast too. Raising the seat seems more reasonable, if this is the problem.

For example, since human frequency response disappears at around 20 Khz, many think that any engineering to widen the bandwidth out to 100-150 Khz is an unnecessary expense.

In my case, I do hear, or at least am aware of frequencies above 20 kHz. I can't tolerate the resonance of a metal dome tweeter. That usually seems to happen above that 20 kHz limit used. I've had to leave a room at audio demonstrations on numerous occasions. They all had metal dome tweeters, when I found out afterward.
