Most of us men spend the first 80% of our lives hurting our health and the last 20% trying to keep what we have left.

How high can you hear and are there any drop outs before it rolls off?
I start dropping out about 13-14k.
Doāt let some minor loss get in the way of enjoying the music, life is too short.

I found this website but I think it is broken. I played the 8kHZ tone and could hear it just fine, but none of the others seemed to work. Strangely, my 15 year old son said they all worked until he got to 19kHz.
Just to check I ran the Tone Generator in REW and could hear 9, 10 and 10.5kHz but not 11kHz.

Neat. On my phone I can hear 14K

Many of us are in the same old(er) boat, but even so there seems, to me anyway, a real presence of having upper-end frequency in our speakers.
My previous build I employed a super-tweeter (guessing āsuperā is now somewhat age relevant - -ouch) and it clearly extends beyond my hearing. But when playing without it and/or rolling it off - something is really missing. Iām a fan of some broad-range drivers for their simplicity (still need to mate for low-end with a woofer), lack of crossover and the way they handle vocals, but the extension a tweeter brings to the table adds that āsomethingā.

At last check, about a year ago, I jad a drop out at 8khz and top end was 14khz. A few years before I could hear 17khz.
I could hear to 14kHz about 5 years ago.
I was a little sad taking the test the other night, but then realized that hearing up to 10.5kHz means I am really missing less than one octave. And although we focus on 20Hz to 20kHz, even most people (or at least males) over 30 canāt canāt hear above 16-17kHz. So, on the bright side, I can hear 93% of the normal hearing range. Blue is 20Hz-18kHz and red is 20Hz-10.5kHz. So, Iām happy again and wonāt quit speaker building as a hobby.

The top end loss can be dealt with, itās one ear not hearing like the other one that sucks.

My left ear has suffered more than my right, many years of driving with window down when I was a smoker is the only thing I can think of. I just adjust the balance a bit when listening to headphones, and sit a little to the left when listening to speakers.

Back to Danny and his exploits. Amir at ASR just reviewed one of Dannyās crossover upgrades and it aināt pretty. In essence, the stock speaker measures better before the upgrade. I bet the fur will fly!

Well, that was interesting - Amir suggesting Dannyās mic may be out of calibration. Canāt wait for the inevitable response with Danny calling Amir & the ASR folks āFlat Earthersā.

One has been in business making products (and mistakes) for approx 30 years, the other takes measurements.
I used that referenced Raal in a design Nick C and I did together and can vouch it does not like to be played very low. Danny missed the mark on this one, thatās for sure. That being said, some of the commenters seem like they would be a lot of fun at parties eye roll
They both take measurements, just one of them is more accurate and transparrent than the other.
Im not 100% full kool-aid team ASR but you canāt deny that the forum has caused some positive changes in the audio world. I do wish they would give some more credibility to listening test but part of that is a limitation of so few testing samples. Like any good test it should have a large sample size and that is hard to do without access to a lot of people and time.
I fully beleive thag Danny can build a good speaker but he doesnāt give each mod the attention it needs to be correctly done. His process for mods is lacking. If he was being honnest he would judge his own work with the same rules that he uses for others. What he did to Linkwits work was a joke and completely disrespectful to a man that has changes the electronics world through doing legitimate work. I donāt think Danny has pioneered anything and I donāt think I have ever seen him write a white paper. Just the gall to use a LR circuit while saying you are better than the L in LR is amazing, I wish everyone could see through the Danny BS.

Heās maybe far from perfect (and has judged and revisited his work) but heās taken his passion beyond being a hobbyist, so just saying kudos for running a business.

If I were a speaker manufacturer, I would invest in a Klippel system. Think of the time savings alone. Let it spin and gather data while you attend to other tasks.
