GPA 902s for 846A cabinet?

[voice of the theater]

I'm not sure how this works with the active crossover Theo is using, but I own a pair of Valencia 846 A's and they are a 16 ohm speaker system as opposed to the 846 B's which are 8 ohm. The 416z woofer that you now have in your Valencias is a 16 ohm woofer and the 902 driver from GPA is an 8 ohm driver. From what I understand, if you were using the stock Valencia crossover, some kind of modification would be necessary to replace the 16 ohm high frequency driver with an 8 ohm driver--but I may be wrong. Can someone out there who's more knowledgeable please let Theo (and me) know if this is an issue as I suspect? I don't think anyone has mentioned this in this thread yet. This thread raises some questions for me as well. First of all, is the GPA 902 driver essentially a model 19 driver? Secondly, does it have the radial phase (tangerine) plug and extended high frequency response that you get from the model 19 driver? Thirdly, if I decide to upgrade my Valencia stock 16 ohm high frequency drivers with GPA 902's do I need to do some sort of modification (as I suspect) to the Valencia stock crossover I'm using to accommodate the GPA 8 ohm high frequency drivers being used with the 416 z 16 ohm woofers? Would the end result be similar to a model 19 in that it's a 416 woofer with a 902 hf driver/811 horn in a valencia cabinet? If I install the 902's, would it be worth my while to replace the stock Valencia crossovers with Model 19 crossoevers? BTW, if I do this upgrade, I'll be sure to keep the original 16 ohm Valencia hf drivers and crossovers so that in the unlikely event that I ever sell the Vals, I can reassemble them to be all original again....

VOT,
Good point. I missed this entirely. All the components I mentioned are 8ohm. My 846B's are as you pointed out, 8ohm. I was unaware the 846A's were 16 ohm. Live and learn.
So, what can happen if you mix?

If one was considering using a GPA 902-8ohm in a 846A Valencia via the stock crossover,there would have to be some modification done to the crossover.

However,the GPA 902 is available in both 8 and 16 ohm versions.

I would be using the GPA 902 via my Altec F-25 active crossover(please refer to my signature at the bottom of this post).My system is a diy active one.No modifications necessary.They've already been made.

The issue of the Model 19 crossover is relevant.The 846B can readily use the model 19 crossover because of it's 8 ohm drivers.I'm not certain that there is an aftermarket reworking of the M 19 crossover for 16 ohm drivers(802/902 plus 416).I've seen the model 19 crossover recommended for Valencias with 8 ohm drivers.

Should I ever decide to sell the Valencias I could easily put the 806s back in.Unlike the 846B Valencia,the 846A allows ridiculously easy access to the internals via the entire rear panel,which merely has to be unscrewed,as opposed to the 846B which only offers access to the cabinet via the driver/horn cut-outs.

Thanks for all the replies fellas.
