I have used these in a 1x12 Fender tweed clone amp and I just bought a second speaker so I could put it in a 2x12 cabinet. I didn’t know much about these speakers until I got used a 1x12 cabinet that came with it for an amp I was building. It is an improvement over the stock speakers that came with my Marshall TSL 602 combo amp (wolverine G12H80) which had a bit darker tone. Now the amp sounds brighter and a bit more vintage like. I bought the speaker used not brand new so there was no break in period for me. On the tweed Fender clone I thought it sounded better than made in China Greenback and a bit more upper midrange than an Eminence Legend.
