Is there a list of full-range speakers (20-20kHz) somewhere on the internet?

I don’t know of any, but speaker measurements have almost nothing to do with how they will perform in your room below 200 Hz. Getting to flat, deep in-room performance has a lot more to do with room treatment, EQ and placement than buying big speakers.

You are also forgetting about dispersion, compression and power handling.

I wrote about this here:

PS - A better way to go is to buy floor standers you like and augment with room treatment and subs if needed.

Also, I personally hate Golden Ear.  I find the tweeters glaring, but clearly I am in the minority. :)

From ChatGPT (Data current to 2022):

While I don’t have access to an up-to-date list of specific speaker models, I can provide you with some general information. There are various full-range speakers available on the market that claim to cover a frequency range from 20Hz to 20kHz. Here are a few examples of well-regarded full-range speaker brands:

1. Klipsch
2. JBL
3. ELAC
4. KEF
5. Focal
6. Polk Audio
7. Wharfedale
8. Bowers & Wilkins (B&W)
9. Monitor Audio
10. Paradigm

It’s important to note that the performance and frequency response of speakers can vary even within the same brand, so it’s recommended to review specific product specifications or consult professional audio experts for the most accurate and up-to-date information on full-range speakers that meet your specific requirements.

There used to be, years ago the Audio Magazine's Annual Equipment / Buyers Guide. Has specs., prices, weights and dimensions of all different types of components and brands. Always looked forward to that edition and I think I still have an issue or two around here somewhere.
