No speaker manufacturer can publish specs based on room acoustics. Grimani attempted to develop benchmark specs. that can be published based on a benchmark using an anechoic chamber. The other guys don’t get it.

Used to be that speakers were rated 30 watt, 40 watt and I consider that to in be totally useless. Non 'philes would look at me dumbfounded when I'd be ask them "what's that mean". There are more useful specs nowadays, but reviewers are finding sensitivity ratings to not be quite kosher. More useful are spectral decay, bandwidth, power response in room, unwanted resonances, distortion measurements, horizontal and vertical dispersion data, photos of the x-overs to judge quality, where a lot of manufacturers use poor quality parts- 'cause you can't see 'em! If not direct from manufacturer, DIY is the way to go.

This was a great video, I wanted to see more slides. I'm hoping that this gets to become a reality. Thank you all.

• Disclose spec parameters. • Use anechoic (or similar) data and not estimated in-room performance. • Report max SPL. • Report bass extension, whether -6dB or -10dB (referenced to mean sensitivity). • Produce a Listening Window graph (smoothed no more than 1/12oct). • State minimum impedance between 100Hz-500Hz. • State dispersion characteristic. I calculate this currently by via the average of the Sound Power DI over a range and arbitrarily stating specific values as wide/normal/narrow/Omni. The above would be in the “brochure” that salesman can give to customers, I want a true spec sheet also available that goes into much more detail.

It's an interesting discussion. Max SPL alone is a complicated topic. For specifying directivity I think you need have a metric for the smoothness of the DI and also a metric for the overall width of dispersion in the mid-treble range.

@@ActuallySettle I don’t disagree, but the more detailed, the more confusing it is to your average consumer. Which is why I advocate for a very detailed spec sheet and a dumbed down brochure.

When discussing + or - 3 db on the freq response should also be measured at a specified smoothing. I would suggest 1/3, 1/6 and 1/12 octave smoothing.

Amazing information. Gracias por eso.

Thanks this was super interesting.

Thank you very much for an amazing work. please continue to educate- this is extremally and will lead to change in the residential audio market

The intro music is quite loud compared to the commentary, I always find myself reducing volume for the new intro vs. the commentary.

I agree, it's kind of embarrassing when I sneak over to watch the newest Audioholics episode at work and this ad blares, filling the entire office at THX reference level :)

8ohm, 6ohm, whatever, most enthusiasts have seen the graphs, and they're all over the place. It takes a bit of knowledge to understand, but having a competent reviewer usually will interpret the specs and suggest if it's easy/hard to drive. Gonna require an amp with more/less current capability. One may have to search out several reviews, if possible.

Perhaps part of the revolution should be an organization, profit or non profit, where a Mfr can take their product to and have a consistent set of tests run on each of their products. The Mfr could then take the results and include a link from the product page to the "industry accredited" testing agency's results page. The organization would be funded by fees collected for testing each product. One twist might be that there could be different levels of testing, you may not need the full gamut of tests on a $150 speaker but would want this on a $2,000 speaker.

Spinorama charts should be in speaker specs. I’ll take speaker A.

How do spinorama tests work with panel/dipole speakers like M/L and Magnepan? Do the results correlate to listener enjoyment?

The pushback was illogical doess a consumer know what 92 @ 1m 2v means? no! Can a consumer Google how loud an imax is yes then they can match that to their home

Insanely great and valuables video …. Love it 😍

Really enjoying the video... Hope you guys will revisit this in some form as this process develops and share it in future videos and in the thread!

All the specs are wonderful but until you have the right preamp combined with the right amplifier and the right speakers all in the same room that can privide a good acoustic experience you will be trying this and buying that. What sounds good in the store may sound bad in the room you put them in. The other problem is the recording industry whether it be live or in a studio , they are not all the same. At some point you have to be happy with what you have but getting there isn't always in the budget.

It's the 3rd post down on our Patreon page and an attached file below the text.

One thing I would like to have seen covered is speaker topology and the effect on SPL at different distances from the speaker. Is there a difference between between a point source vs a line source vs a panel speaker. I think a spec should define the SPL at 1 meter, 2 meters, 4 meters, 6 meters.

Mr Olive what happed with Lexicon? They dropped the ball I have an RV-6 and I've had Lexicon products they alway have a remote control issues these models were discontinued so fast it's a shame

next time can we dump Anthony Grimani....he just took over and never let the others speak....

I agree with you. we really appreciate Audioholics and Gene gathering those great names in the audio business, but in my opinion Anthony just didn't let anyone to engage especially that he is all time on the channel, we never had the chance to have Dr. Sean before on the channel which i was waiting for since long time ,so it would be much better to divide the time between them fairly instead of 1 side lecture. I love audioholics though and Gene you are the best!
