I rebuild one and sold it, I don't care to much for their sound. But the drivers were pretty good. The piezo tweetsr is redundant in them.
Awesome! Thanks for watching.
先锋早期的古董喇叭貌似是前JBL的工程师做出来的，从外观看来有很多JBL的影子
Yes, absolutely right! Engineered by Ed May… JBL L series, Pioneer HPM series and later Marantz hired him to compete the JBL and Pioneer with their DS 930. Please check my videos on Marantz DS 930…. Thanks 🙏 for watching.
Looks like a quality woofer. Good work by you.
Yes, it’s Pioneer HPM. Thanks for watching.
