Hi, long time reader first time poster :)
I've got a set of a-7's, 416a woofer, 511b horn, the sticker on the driver has fallen off. Anyway, I would like to try out a new dividing network but would appreciate some guidance. I don't see a direct replacement on eBay (Canada at least) nor the great plains site. Where should I look?
Thank you so much.

A-7 with the 511 horn people want to use the 500 HZ crossover. But if you are willing to use a 700 or 800 HZ crossover you can double the RMS power capability to the horn. The diaphragm operated below 800 HZ has to much diaphragm displacement and will cause the suspension for the voice coil to fail before the voice coil. BY crossing over at 800 hz the displacement is lowered significantly allowing for higher out put levels. A 416 woofer does well up to over a 1000 HZ so there should be no issues, I preferred to use the N1200 crossover myself as it allow adjustments of the HF and MF of the the Driver. It also gets rid of the honking sound of the 511 horn. You want to keep the 511 horn as it has the same directional qualities and the short horn of the woofer box and is one reason a lot of people like the combination. Just make sure the voice coils remain in vertical alignment for best results when crossing over.
