How much do you expect this upgraded version of the speaker to cost once finished and where do you anticipate its performance to be when compared to your lower line speaker kits?

Just looking at parts on the GR website you're looking at around $120 for the pair.  Plus another $38-76 for No Rez.  You could reduce that price quite a bit by requesting Erse caps which are still pretty good sounding.

Danny,
Here is a switch that might work.  A Cherry DPDT rocker with 12 Amp contacts.

Too hard to mount in the back of the speaker.

I need one that will fit through a drilled hole.

Also a SPDT switch will work.

Actually all the rocker switches are for panel mounts that I find. 

What I was thinking from looking at the data sheet is that the two side catches will go flat against the body when it goes in the hole.

Some electronic grade RTV around the top and you have a good seal to the wood cabinet.

Just an idea.

The NKK switches look good for high current (15 amp) switching.  Here is a SPDT locking one that uses a hole to mount.

They are in stock as well.

Okay, I have some switches and might be able to get started on this sometime this weekend.

I have been really busy filling orders....

What little time I have had (late in the evening) I have installed the switches right into the binding posts cups right above the binding posts. I also have assembled the crossovers using Sonicaps.

More still to do and I will get back on them when I can.

Thanks,

Danny,

Are you altering any of the values of the upgraded crossover compared to the stock one, or just building a new crossover with improved components?

The stock crossover was replicated and values were matched.

Love to hear about any further updates on the x-over test and measurements.

cheers.

All of the measurements of the stock crossover was posted. The new one is an exact replica, so the measurements will be identical. I test one of them with the binding post cup removed to and the wires from each driver feed straight out the back. The two curve (one from each crossover) was exactly the same.

I had not time last week to work on it further. So I will try to get back on it this week as time permits.

I worked on them some this weekend and got both networks installed with switch.

Okay, I had a little time this weekend and got back on these and got them finished up.

They shoot almost identical curves with both networks. It may have a 1/100th of a db difference in the response here and there but not anything anyone can hear. For the most part the two curves lay right on top of each other.

I did have to add another switch in the woofer circuit of each speaker to break those components out of each circuit. So I managed to get three switches all into the stock binding post cup. All up for stock crossover (top binding posts) and all down for the crossover using Sonicaps, Erse inductors, and a Mills resistor (lower connectors).

They are going to need to burn in for a while now.

I did do some listening to them already though, and they REALLY sound like they need burn in time. No real surprises in sound between the two networks other than one thing. The higher quality crossover always sounded slightly louder when switching back to it. Output levels measure identical between the two, but the transient response is different. The higher quality crossover allows every peak to come through as such while the stock crossover softens and rounds off the peaks. It tends to smear them together more and blur one to the next.

This my be real enlightening for the nay says that will get to compare these.
