Few speakers speak ‘classic rock’ like the Neodymium powered Tornado Stealth 65. Sharing a similar 1 ¾” voice coil design with the Nighthawk, it delivers vintage and modern rock tones with ease and authority. With a well-controlled top end, a typical British-voiced midrange and fat, warm bass range, the Tornado Stealth 65 is an ideal choice for classic flavored rock tones. Very easy to drive for any amplifier, it allows even the smaller sized open back combo amps to rock with bigger-than-life tones.
I recently bought a Marshall Silver Jubilee 2525C and I wasn’t 100% satisfied with the tone of the speaker. Nothing wrong with a greenback but maybe not in this specific amp I think. I think it was to0 bright. I tested three different speakers that I had on the shelf. I started to Google and I decided to take a chance with the Tornado Stealth 65 that seemed to be exactly what I was after. This was the perfect match for my little jubilee. Not super efficient and not too bass heavy. It has bass and lower mids but not too much and the higher frequencies are perfect, that was the weakness with the greenback but not with the Stealth 65. I would say the description on the site is a honest one. I have now the Swamp Thang in a 1x12 cab ready to use together with the internal Stealth 65 in case I need more volume. Great speaker and it is great with the cleans too.
