Always fun learning more.......
Many thanks to Giskard for the photo and to Greg Timbers for the graciousness to allow us a photo of his living room.
Paying debt to Karma...
Horn systems are not dead!
Thank God for us horn fans!

Fantastic
looks like array so much.
He is a JBl master now.

It is actually the inspiration for the Array Series. This is what started it all. This is DIY at its very best. The Array Series wasn't elicited by Marketing or Sales at JBL. The system concept and implementation are by Greg Timbers.Originally Posted by northwood
Oh! By the way - please don't get the impression that he's done.
His system and mine actually have one component in common. OK it's just the Dish Network 811.
A big thank you to Mr. Timbers and Giskard for sharing the photos and info.
Nice to know GT's interest in 4-ways is still there. So when are the DIY plans going to be listed
I'm crazy for his workOriginally Posted by Giskard

NEVER, but they can be improved upon with different boxes and CC crossovers.Originally Posted by Titanium Dome
That GT System really looks like something to have...
Hey Giskard what were the crossover points, did he say?
There aren't any.Originally Posted by JBLnsince1959
~ 80 Hz, ~ 800 Hz, ~ 10 kHz
I'm not real sure about the 1200FE to 435BE frequency. That crossover is handled by the DX-1 with cards custom made for this specific system. I think the low pass is something like 24 dB/octave and the high pass is 6 dB/octave and very likely charge coupled based on past conversations. Greg had to manipulate the card to get 24 dB/octave on the low pass. My guess would be maybe as low as 650 Hz. It depends on where that particular prototype horn shuts off. Maybe 750 Hz.
i think the aesthetics are better in the GT system than in the commercial version. the "heavier" base better offsets the tall vertical horn.
Hi Giskard,
Thanks very much for your insights & personal impression of this prototype system .
As much as anything, I'm intrigued by the usage of the 1200Fe .
As a fan of just about any high power 10" made by JBL, I was somewhat taken aback to see their exculsion in favour of a 12" ( but then you offered up your speculation on the crossover points & it then made sense ).
Thanks again <.
Could it be, Earl, that the thought is a 12" would be a better FR dispersion match to the horns in the range of cutoff points used in the crossovers? Smoother overall power response. Also, some additional weight and margin for high levels in the low-end power range to match with the not-quite-sub woofer.Originally Posted by Earl K

I'll bet the mid-bass on that puppy is smooth and full. I was wondering if he had it around 80 to 100 or around 250
I personaly like 12"ers better than the 10"ers in the 250-300 to 700 range ...just more there...
anyway thanks
I quess we can only dream.......dream hell..I'm saving my money up. "hey Hon...would it be OK if we didn't travel for 2 years?"
I agree with that..Originally Posted by qxlxp
What really makes me weak in the knees is that I just like the 4 way with the 12" mid-bass plus it has the beryllium horns........Can you imagine how much that would be retail????
