Need some help on the wiring for a BFM Omini 10.5

[rwillett]

Hi,

 

I was lucky enough to have a BFM Omni 10.5 with four tweeters donated to me by @neepheid at the NW Bass Bash. 

 

It was a fine sounding cabinet when we tried it out with @Mottlefeeder Warwick Gnome amp. The more discerning amongst you will notice the past tense in the previous sentence. There was an issue with a switch that sometimes seemed to work and sometimes not. So I decided to pull the back off and have a look at the switch with my multimeter. I assumed a loose connection.

 

As I removed the back of the cabinet, I somehow managed to disconnect one of the cables to the bass driver. The bass speaker is a rather nice "Eminence DELTALITEII2510 10-Inch Neodymium Series Speakers - Series II" according to Google reverse image lookup. To be honest I'd never have got it from the markings on the speaker itself but that's another story.

 

So one of the bass speaker cables is off and I can't work out where it came from. I think it's one of two places, either the red square or the purple rectangle. The light green is the end of the wire. I've checked the BFM website and community section but it's light on photos and so have come to bow down with sackcloth and ashes and ask for help. This is so embarrassing.

 

Oh and if anyone has a Warwick Gnome for sale, ping me a message

 

Any help welcomed

 

Thanks

Aw no, that's too bad!  I wish I could remember how it went, it's been a while since I was in there.  Where is the other wire from the speaker going to?

[rwillett]

The other speaker wire goes to the other side of the choc block next to the red square.

I don't think it actually goes where the red square is as there is very little gap at each end. However logically it might do.

I replaced the large, white resistor a few years back, because it actually physically broke apart - it ejected its legs.  I briefly discussed it here - https://billfitzmaurice.info/forum/viewtopic.php?p=294776 and I quote Bill - "When it broke off the only result would have been the tweeters shutting down."  That leads me to think that it's the red square - if the main driver was connected at the purple square, when the resistor broke apart, it would have taken out everything, no?

 

If not red square, then maybe above it - can 3 wires fit in one hole of the connector block?  Now that I think about it, there's a vague memory of swearing and trying to get three to play nice, but I might be misremembering...

[rwillett]

It's possible that three wires might fit in there. I could imagine a lot of swearing to get them to fit as well 😊

 

I read the comment on the BFM site. Basically it has to go there in front of the square resistor. 

 

I'm going to look for bigger connectors though those look quite big.
