Hi, Like you, I'm thinking about Transcendent's new class A OTL. I have no experience with 16 ohm pro drivers. How about a Pro 4 Pi using 16 ohm JBL 2226j or a Theater 4 using a Delta 15 16 ohm driver? Compression drivers are available too. My question is can three watts move a pro woofer very well? Please let us know what you decide to do. Maybe with a single tweeter you could wire two Alpha 8 or 10 in series Good luck, Steve
