Newbie with questions over crossover
Posted: Mon Mar 30, 2026 4:38 pm
Hello,
Just for background its maybe worth mentioning that I am a reasonable wood worker, I am from UK but imperial units don't scare me and I can very much solder but I don't have a deep understanding of electronics.
I have bought Jack 12 plans in order to have some PA speakers for my band when we play (once/twice per year to a small crowd of sympathetic ears) and to provide a bit of a music system for small parties in my folks garden (maybe to be extended with some subs at some point). It seemed like the Jack 12 fitted the bill for a first go into making speakers and for what I may need. I have read the plans and it looks like the planned 12 inch woofer (in my case a Delta 12a) has a crossover design which needs 2 ASD1001 tweeters per cab which results in the crossover being 16 ohms. However, I need the speakers to be 8 ohms to go with my amplifiers that I already have. What are my options? Can I just go with one ASD1001 per unit? Where can I get details of the crossover for this - I am really not going to be able to design anything on my own so any help much appreciated.
Thanks for any help in advance,
All the best.
P.s. I cant buy the piezos here at the moment for a reasonable price from what I can see
