Hi,
I am building a DrGeddes sub system and I have found suitable
two big 12" drivers for the floorstanding subs, but I am having trouble finding a small 8"sub for the sub placed high up.
The JBL GTO 804 was/is a very interesting elements and would suit my needs perfect .
It has several nice parameters, here they are:
Fs 29
Vas 16,
BL 12,
Qts 0,42
Qes 0,
Qms 6,
Mms
Cms 251,
Le 1,64
Re 3,
Xmas 11,5mm
Is this driver still produced? Every place that says they have them says no longer available..
The driver I need, if the GTO is out of production doesn't have too be an 8", it could be a 10" also but it has to fit in a small box as a 50L cabinet placed high up wouldn't be so nice looking..
I have searched and searched on different sites selling elements but I can't find anything that matches the GTO, which really is a pity,
Do you guys with much more knowledge than me know if it is available somewhere?
Or if not, a driver that matches the GTO?
I thank you for you help in advance and hope you all get a nice Christmas!

I just remembered that TB does a nice 6,5" sub, with very alike parameters. The W6-1139SIF.
It would probably need a smaller cabinet, I'll be losing some output but it is the sub that will be placed nearest me so the level would be turned down against the other bigger ones further away from me, and should barely be noticeable, that's how much it should be turned down.
It is cheap too.
What yo you guys think? Could it be a good match?
The two others subs are 12" and with 15mm Xmas, and they are the ones that will be putting out almost all of the sound.
This third small sub is more for smoothening the room modes/nodes(?)
Again, thanks for all the help// JK
