If you get a chance checkout the LaGuardia Airport Marine Terminal. It is where the Pan American flying boats like the Boeing 314 were kept in Flushing Bay. It's beautiful and the murals inside are...

Hello Widget

I didn't realize the Everest's were difficult to integrate into a room. That does make sense though having the woofer's that low. Don't recall anyone complaining with 4435's but I do...

Hello Ian

I have a couple of questions:

Is he using he 045Be or just running the 476Be all the way out. Could he be using a 476Mg??

What is the horn/waveguide based on?? Is it similar to...

I found it interesting that he ditched the Everest cabinets, kept the drivers and made his own cabinets because the Everest cabinet was holding him back! Love to get a better look at the horn he is...

And then there is Klingon Opera!

Hello Ian

Just adding a little clarity. For Constant Directivity systems, think 4430 where the on and off axis response are very similar you would get the most benefit. With system using beaming...

Thanks Earl for posting these.

Went back to revisit this and the links seem to be working again?? Do they work for any of you as well??

Hello Ian

Glad you are feeling better. Carry on!!!

I am on the opposite coast so I don't know your local situation. I would look for authorized JBL Repair in your area and talk to them and then do a search on them to see what the deal is. The easiest...

Hello

Nice score!! Depends on your skill set. The only things you would need to do is reflow solder connections if needed and Deox and clean the switches and pots while you have them open. Those...

They are the wrong ones. What do you expect for 16K!

Hello Dan

If I remember correctly I called them on the phone. That was a while ago, I would just try again.

Rob

I don't understand the confusion. This speaker systems were made to be used as LRC with a sub. You are going to have a very hard time coming up a better use of these drivers beyond how JBL designed...

"So the instruction on that page for how to modify the links is incorrect, right? Is it possible to have that updated by someone with access? I realize correcting each link is a monumental job for...

Both compression drivers have 100 ul of APGS38N ferrofluid in the gap. The ferrofluid provides some damping and seals off cavity resonances. Without the ferrofluid the curve gets...

Very nice! They look great!

The 2453 comes with an integrated back cap. The 2452 does not. Do a google search for images. H and J are interchangeable.

Hello Edgewound

Yes and the 1400 has the DF slot vertical which makes a difference with the imaging. That was my point the M2 and 1400 waveguide/horn don't image the same way.
I find the M2 more...
