I put this speaker into an old Japanese 15 watt electric guitar practice amplifier which was made in 1980. I guarantee you have never heard of the manufacturer which is Chukyo Denshi. Among other similar Japanese knock off brands, it is a a copy of a Panasonic which was a copy of an American classic. The point being that it was cheap and poor quality and contained a car speaker of unknown origin. However the solid state circuit design was sound and I set about replacing all the transistors and electrolytic capacitors with quality components like Nichicon Muse. Along the way I repaired the tremolo function by replacing a faulty transistor. The Jensen JCH615-4 was an ideal replacement for the 4 ohm, 6" speaker of unknown origin which the Japanese put in. The best part was that I never had to drill new holes or put in new T nuts, it was a perfect fit. Now the amp sounds a lot better. The speaker makes it sound like an amp which cost hundreds of euro as opposed to dozens of euro. It's not a Fender Bassman or a Marshall Superlead but it sounds pretty meaty and the tone from the new speaker is a huge improvement. I play a USA 1992 Fender Strat with an on board pre amp and the thing chimes like a bell through the Jensen. The tone is really good. I like to chug away on it for hours as it sounds class, both in clean and distorted settings. Because it's 15watts, It will not damage your hearing or annoy the neighbours. I am now considering making a cabinet 4x6" of Jensen JCH615 speakers wired in parallel to make up a 50 watt array for my Marshall, which has a 12"x1 EVM12L. if we have another lockdown.....it's gonna happen.
