2way speaker using Fostex F120A 5" full range driver and Fostex FT90H horn super tweeter with Alnico magnet both. These vintage drivers are designed over 20~30 years ago but F120A is still available. Modern FEM computer aided design speaker unit like Seas and Scanspeaks sounds smooth, clear, perfect low distortion, in comparison, vintage high efficient unit with Alnico magnet sounds straight, vivid and high contrast.
Direct heated triode single ended DIY amplifier using EH-2A3 (non NFB) is well matched.
