Honestly, it's almost become trendy to trash talk T75s. Poor online comparisons fueled that. They are a speaker that has a super tight lowend, really crisp highs and requires an amp's mids to be pushed upfront.
If you record them with an amp's settings tailored to V30s, G12H30s, Creambacks, Greenbacks or the like then you will get lackluster results.
When I hear someone slagging T75s, it's a sign that they have poor eqing skills.
