Review: Proper detailed sound - From 1 to 10 is around 8. For this money perfect
Review: I recently bought a 30 year old Technics midi system and was disappointed that the sound quality was muffled and overpowered by bass. It turns out the tweeters had blown. I replaced them with these and wow, they've breathed new life back into a vintage hifi. To install them I had to cut a small notch into the speaker cabinets to accommodate the connectors which sit quite proud of the rear magnets. I also had to desolder the capacitor which is attached to the positive connector as my speakers have a built in crossover, so it wasn't necessary. Bear in mind that the tweeters are supplied in pairs which isn't clear in the product details. I've ended up with two pairs, but will be using the spare pair to upgrade another pair of vintage speakers.
