Do you need high end speakers for rock and heavy metal?

[Sokel]

Perhaps good PA will make it?

Make that control room's main monitors and you're close.
Put a nice finish to them or, put a REALLY nice finish to them and you're there.

Plenty around, it's only real estate.

Get the Klipsch the Nines and shut up my dear ; )

Kidding but näeh, no so callled high end speaker can. Particularly when it comes to high, clean and uncompressed SPL. Perhaps you can specify a bit
more what your understanding of "high, clean, and uncompressed SPL" is. Perhaps good PA will make it?

To me, metal needs, as every genre, an "uncoulored" speaker, a bit of room treatment and a bite of DSP to fit taste.

I’m not familiar with the Klipsch Nines specifically, but I doubt they exhibit anything close to a neutral response.

When I said high-end, I meant it in the truest sense of the word -as in, uncolored and accurate, not the typical “audiophile” interpretation you might be thinking of.

And yes, some PA speakers could definitely fit the bill for what I’m after. But those capabilities aren’t exclusive to the PA world -there are non-PA designs out there that can deliver similar performance. A common characteristic among them is the use of large bass and midrange drivers.

Actually they do - although low bass is overdamped:

Sidebar 3: Measurements I performed the measurements with the Klipsch The Nines Primary speaker (serial number 107128623160250). Before I started the testing, I installed the Klipsch Connect app on my iPad mini and paired it with the speaker with Bluetooth. I used the app to set the equalizer...

Why use Stereophile measurements when we have Klippel via Erin?

(I have no idea why that's getting a "Klipsch In-Room Gold LCR Review" subheading, guessing that's an error on Erin's end.)

TL;DR: They're actually quite good. Shelf the treble down a couple DB and they're quite accurate. Good bass extension too. Only real issues are that they will employ limiting when you get past 90dB/1m, and rather narrow horizontal dispersion (though I hear some people actually like that).
