Playing my TB153 4ohm w/Markbass F1 head, JoBo 5er bass with a traditional c&w band last nite. In mid-song started to hear distortion on low notes.
Anything from about below low-G sounded distorted and like it was coming outta the 6" mid. When I played above; about low-A on up no noise with volume lowered. I took the bass and low mids outta the head, lowered volume knobs on bass, it got better. Even then playing any low notes again distortion came right back.
I used this cab, same band, same room, same head, same bass a few times in the past and at louder volumes. Was a small crowd so we kept our volumes down. This distortion just came on suddenly in a slow ballad of all tunes. Maybe its' just a loose soldered wire or something. I'll open it up soon and check out the insides. This is the older X-over and I'd read where some had issues with that. But that was usually noticed right away, like right after they bought it or played thru it awhile. I've owned this cab since last summer.
With 7 other cabs that I rotate for my gigs in different bands, it has never been abused or blown out volume wise. Again, could be something loose. Wondering if the 6" mid could have blown or just that older xover haunting me like others have had?
If I don't see anything out of ordinary when I open it up, I'll call Dave @ Avatar, I hear he's pretty cool guy.
Anyone resolve similar issue recently with their about year old, 4 ohm TB153? If so....what was it?
