B&C DCX464 - Page 35

I guess BC is letting us 'home hifi' guys figure it out on our own. Kind of makes sense since most of these drivers will be used in the pro gear world actively crossed over with DSP etc. No passive crossovers in that world. We are just too small of a market

The horns I am playing with run down to about 500hz to 300hz. I guess you can pick your flavor of 'horn'. There are a bunch of them out there!!

B&C just came out with a passive crossover and measurements :

FB4648 Crossovers - B&C Speakers

There is this one as well, mentioned earlier in the thread.
Looks more interesting than B&C's own crossover IMO, since it adds impedance compensation and HF EQ;

Convair Custom Crossover for B&C DCX464 16 ohm Co-axial PS25.50 IN STOCK (21 Jan 2021)

Yes I tried to get it but not available in the US....don't know if I am getting something wrong but will try to contact them again. Any other way to get it to the US?

Will they not ship to the US? Looks like Blue Aran in the UK is the only distributor/dealer for Convair electronics. Anyway they give alot of information about the XO, all values are shown on the board layout schematic, so maybe you could build your own.

I guess that was pretty recent!! I bought two, FB4648, from Parts Express just now! Now I will have something to A/B with!! I am assuming they used their ME464. This is great news!!! I am excited to get these up and running!!

Those went fast!! I guess I got the last 'one'. They are now backordered for 30 days.

Hope you get what you ordered...I've been having terrible problems with PE delivering what the web said they had in stock

There is schematic in datasheet https://www.bcspeakers.com/en/produc...0/8/FB4648.pdf
