The large Advent loudspeaker was released in 1968, designed by legendary sound engineer Henry Kloss. His goal was to create a budget friendly speaker that could compete with models that were far more expensive. The original Large Advent (OLA) went on to develop a cult following and garnered attention for it's incredible sound when stacked two pairs high. In the 70's the speaker was updated to the New Large Advent (NLA) with a different tweeter placement and updated woofer. In 1980 Advent released the 5002 and 5012 versions right before being acquired by Jensen who kept the models around for a few years before discontinuing them in the mid 80's.
A few months back, I was lucky to pick up a set of the rare 5012 variant locally for a good price but they had some issues, the main one's being that the woofers needed to be refoamed and the woofer in the later production run speaker was frozen. Because one of them was manufactured before and the other manufactured after Jensen bought the company, they had a few differences in the fit and finish as well as the type of driver that was used. While refinishing the cabinets and updating the crossovers with new capacitors, I also decided to replace the grill cloth. Overall, these are the best sounding and best looking pair of speakers that I've restored to date.
They are currently listed for sale because I do not have the space to keep them (very sad).

My name is Matt. I live in Washington State and create content around vintage stereos and other audio equipment. I approach the hobby from a technical standpoint and am learning about circuit design and reparing and calibrating amps, turntables, speakers, etc. I really appreciate a good aesthetic and the vintage stuff fits my taste.
