    JBL Studio Monitor GS-115

    Just picked up a pair of these. 2 way monitors with 115H woofer and what looks like a metal dome tweeter. Can't find any info on them. Has anyone come across these before?

    They sound pretty good considering the woofer foam has had it... possibly a little recessed in the mids for my taste but not bad at all overall.

    Any tips on a good source of replacement surrounds? Drivers themselves are fine.

    Also what are the thoughts around here on the merits of recapping the crossovers?

    They are probably model 4401s

    No, not quite. They're rear ported. No tweeter level control, and the tweeter is not cut off at the bottom like the 4401 (if that makes sense).

    I think maybe they're a UK/european market version of the 4401.

    Anyone?

    Started pulling the old foam off the woofers tonight only to find the surrounds I bought on eBay are completely the wrong size...

    Lovely little woofer, though! They don't make them like that any more!

    Gs 115

    Hi

    I just found this thread while idlely googling to see if anyone else is still using these

    I bought mine new sometime around 1990 and they are still in use.

    They were made especially for Turnkey in charing cross rd, as I remember it and were very cheap (250 a pair or maybe even 200)

    I wet in to get some Yamaha NS-10s and was persuaded to get these jbls instead

    They were aimed pretty much at the emerging bedroom dance production market and consequently have a bigger bass than they probably ought to, (which was of course quite useful in the turnkey demo rack where they sounded much closer to much bigger models than the NS-10s i was comparing them with)

    seem to remember a sound on sound review around the time.

    also one of them developed a rasping sound in response to low frequencies, so I took it back - didn't do it in the shop but they replaced it with their demo one.

    They both now rasp as soon as any sub-audio or distorted sound goes through them, which is one of the reasons I still use them as a sort of early warning system for problem sounds.

    Very nice, thanks for sharing.
    Can you post some pictures of your speakers?
    I'm not familiar with that model number!

    The tweeter certainly looks like the 044-1 which was used in the L250.

    I agree. Thoose edges looks very homemade.

    I'm a little surprised to hear that a respectable company like Turnkey would have risked damaging their reputation by selling 'fake' JBL's

    Apparently they outfit the finest recording studios in................... the Czech Republic (if you look closely you can see them in the picture): http://www.videotelefon.cz/yrena/sokit.htm

    Also found a reference in a document applying for a radio license in Ireland: http://www.bci.ie/documents/r_na_l.pdf (page 37)

    So, perhaps they are in some way real, if certainly not produced in extremely limited quantities.... :dont-know

    I did see these on Ebay and the close ups of the drivers showed a bad refoam job. The dustcap even looks too big. Of all the drivers I`ve refoamed, none of them had the wires and black glue going under the edge of the cap.

    You can even see the stamp "044-1" on the back of the magnet in the photo. That plus the goldish-looking tweeter diaphragm and the fact that there are no mounting bolts on the baffle, all has me speculating they made these up of surplus parts. Leftover 044-1 tweets from when the L250 went to the 250ti? Where else was the 044-1 used, that we know of?

    No where else that I know of - the "goes into" list I have only shows the L250.

    So I guess the folks on the forum aren't the only ones who put together speaker systems with extra components that are laying around....
