Me vs. JL Audio - An open discussion.


An audiophile ( dpac996 ) in another thread:


https://forum.audiogon.com/discussions/eh-hem-subwoofers-what-do-ya-know


found a very interesting, and IMNSHO, very messy, post from JL Audio:

https://jlaudio.zendesk.com/hc/en-us/articles/205061040-Adding-a-Home-Audio-Subwoofer


It has some great points, some confusing points, and some word salad. Kind of like a recent Star Wars movie.


Mind you, I think JL Audio has among the very best room correction software out there. I find myself agreeing very much with the choices the software makes, but still, this article has some great things in it I want to bring out, which I'll do in my replies.

I was first gonna slam and then epically eviscerate ieales (with one hand tied behind my back) for that first one. But then came this:
As a composer friend once opined after hearing my system and enquiring "Those little speakers aren’t putting out all that gorgeous bass?!?!?!?" … "Every other subwoofer I’ve ever heard just boomed!!"

His great appeal to authority is a composer. Hey ieales! You mean, like Beethoven? The famously deaf composer? 

I have indeed met my match. IMNSHO, of course.








I tried to read the JL article. Really, I tried. But I have this problem. Always been a problem, but seems to be getting much worse as I get older. The problem is first of all, I’m really good at spotting crap. And second of all, and this is the part that gets worse, the growing lack of patience dealing with nonsense, especially from people and sources who should know better. This JL Audio piece with all its bold statements and bold fonts highlighting the BS has my meter pegged.

So instead of commenting on all the crap and word salad nonsense, which would take like forever, here’s the one tiny little bit they did get right:
The only correct way to add a subwoofer to system is to define everything above the subwoofers range as an entity;... and then ... the subwoofer is one way and everything above it is the ‘other’ way.


Notice the ellipsis (...)? That’s because even around this one little bit they did get right is a bunch of stuff they got wrong. The part they screwed up is cut out. Thus ....

That’s it. The one thing they got right: low bass is one thing, midbass on up in frequency is another. Of course they can’t say "thing" they say "entity" which is just bad writing. People with little to say and even worse understanding always think big words will make up for their lack of content. As. If.

The truth is everything above the sub really is a whole different thing from everything below. If all their timing technobabble was even halfway true then a mix of four or five different subs randomly positioned around the room would surely be the worst possible bass. Instead of the best. So there you go.
