As there is so many speaker measurements results presented here, is there a simulator using the data for different speaker placement and room size? Could be useful. I was not thinking of REW but something doing this directly from the data.

I am not an acoustician and have no experience with any acoustics simulation software (including the two I mention below).

I haven't come across any "simple easy to use" software, but there is an open source sound modelling software called I-Simpa. A commercial software that seems to be quite widely used is EASE.

Does any software use spinorama data to do the simulation?

Isn't spinorama predicted room response itself a predicted response

Their people probably know what happens in different rooms

Yes, it does present a room curve based on different percentage of direct, reflected sound and power. What I am looking for is a combination of speaker data + room simulator (e.g that in REW).

As far I remember from university, acoustic simulations are still far from perfect. They are only accurate for stochastic and geometric model. Frequencies under Schroeder Frequency, which includes wave theory model and X area are not considered. That means in typical, small domestic rooms (0.8-1.2s reverberation time and 20-30 m^2 area) everything under 200 - 400 Hz is not really modeled.

AFMG EASE and Odeon are two main choices. This software is really expensive - thousands of euros for one license. Definitely not accessible for hobbyists.

I heard there are some simulators only for bass frequencies based at wave theory but I don't have any experience with it.

Some speaker manufacturers, often free of charge offers their own simulation software. This is however usually targeted for line arrays or other professional applications and don't include other manufacturers speaker models.

All in all I don't think it is really possible for hobbyist to simulate acoustics and speakers in domestic applications.

I tried I-Simpa, but the interface was a bit too confusing for me. These things are not designed to be easy to use, I even had trouble even creating a space and a sound source.
