Haven't you had these speakers over a year now? It'll depend on your amplification whether you can reach reference level of not.

Reference Volume is 85db with 105db peaks. It also depends how far your listening position is from your speakers. You'll need a SPL meter to measure this. Do you have one?

"REFERENCE VOLUME" is a meaningless concept. That's like asking "how good should reference sex be?"

If you can play at the volume that is satisfying to you without significant distortion, that is all that matters.

Some speakers certainly can play louder than others before distortion occurs, but "reference volume" is a nonsense concept.

If you want a meaningful absolute measurement of loudness, you need to get a sound pressure level meter and measure it, in dbA.

The EXTECH 407703A is a good SPL meter.

If you get a SPL meter, be sure to get one with an analog meter; digital readouts are useless because they do not indicate momentary peaks in the sound.

At $156 that model SPL cost almost as much as his receiver!

This is true.

Amazon has it for $63.

Grainger is pretty much overpriced on everything.

There are cheaper ones, but they have very limited frequency response and measurement range

That is your opinion, reference is a set of standards and the OP wants to know if his speakers can do it, very simple question. It has nothing to do whether you or anyone likes reference levels. He needs to calibrate his speakers correctly, turn it up to say -10 dBs under reference and listen. Not loud, too loud, speakers OK, not OK, and go from there. Just don't crank it to reference as it may cause damage to the speakers if they can not handle it. If he does not own these speakers we can get a good idea based on his room and specs if they can or not.

Again, whether you like reference or not has nothing to do with this thread so it does not help. The only theaters that I know of they actually play this loud are IMAX theaters so if they are too loud for people then reference should not be a goal. If you go into IMAX and love it than you have tour answer. BTW, it can sound just as loud and impactful as IMAX but better.

IT IS nonsense, because the Audio Engineering Society has yet to define it, and if the AES does not recognize it, I call it nonsense.

They are the body that sets the standards in the audio field, and have been doing so for over 100 years.

To define a "reference volume", you would have to do so by setting out a long list of parameters within which that "reference volume" would apply, and then you would have created a definition that would only apply to a very specific situation. It would hardly be a universal standard! Its application would be very limited, and not useful in a general sense.

Some people say that "reference volume" is produced when the volume readout on a receiver says 0 db, but this is completely stupid. It is obvious that if you hook different speakers with different sensitivities to that receiver at that setting you will get DIFFERENT VOLUMES, not some "reference volume"...duhhh. You will also get different volumes at different distances from those speakers. The indication "0 db" on the receiver is just an AMPLIFIER GAIN SETTING that IS ONLY ONE OF MANY VARIABLES that determine actual VOLUME produced by the set of speakers that may be connected.

We are talking movies here you know. Very specific, audio or music don't have reference levels.

The AES is not a standards based organization though charged with setting them and then defining how to measure them. As to reference sex, that's something no one who has dated Taylor Swift has ever experienced.
