BG Z-92

Now that this speaker has been discontinued by BG would anyone have access to the crossover diagram and the midrange internal cabinet design? I have no crossover design experience but someday want to give the NEO 10 a go and want to see how they handled its response electrically.

I have one that I purchased a while ago on a clearance. The midrange chamber is not that larger. I am going to guess about 6" deep. The crossover does not look very complex for a 3 way. I am going to open it up again to change of the fill material to some Bonded Logic, so I'll take a better look inside for you then.

Thanks ...post a crossover diagram when you are ready...from ZAPHs measurements it looks like it may be as hard to work with as it's little brother the neo 8.

Here are a few shots from when I first got the thing.

Also a short of my close-up sweeps taken at 3". First unfiltered and second with 24dB/LR electronic set at 300 and 2KHz.

Here at my sweeps of the complete Z92. I will be addressing the peaking btw 10-20KHz. First is horizontal at 0, 15, 30, 45. Next horizontal.

And one of my project using the Neo10's in my main system. The Z92 will be my center channel.

If you are refering to the Z92, that comes from Bohlender Graebner, premade.

My speaker has to Neo10 faceplate, just 2 of them pushed close together.

You might try Madisound here in the US. They make faceplates for the Neo8 and newer Neo8S. They might consider one for the Neo10 if enough people ask for it.

Talking about your speakers.
I'm also planning a 3-way OB similar to yours (Raal + 2xNeo10 + 1x15") and found faceplates for Neo3 and Neo8, but not for Neo10.
I will contact Meniscus asking for it.

Thanks
