The Celestion G12T-75 sounds smooth and the frequency range that comes through is wide. The speaker emphasizes the lower mid frequencies and lets very high frequencies through. It lacks pronounced upper mids and can lack presence and could potentially prevent your guitar from cutting through a complex mix but it still sounds great by itself. The speaker sounds good when pushed and does not begin to sound harsh when played loudly. To me this speaker definitely prefers to be used in a closed back cabinet. However I have used it in an open back Fender Deluxe Reverb Reissue and it can work good there as well even though it takes some of the “fender“ out of the sound. This speaker is the classic choice for 70s heavy rock sounds. It sounds great in a closed back cabinet with 70s style distortion playing through it and delivers a warm meaty bottom end. I have also used the speaker along with a Celestion Vintage 30 in a Marshall cab. These two speakers compliment each other well because the Vintage 30 produces the upper frequencies that the it lacks and vice versa. Together they provide a full wide frequency range. I have also compared this speaker to the Celestion G12t80 which is found in countless stock. I've learned that you never know what will work best with each particular combination of guitar/amp/cab/and speaker. When I play my semi-hollowbody Triggs 2 guitar with Alnico humbuckers through my Fender Deluxe Reverb Reissue with volume on 10 through my Marshall 4x12 cab, the side of the cab with the G12T80s sounds better for some reason than the side with the G12H30s and Vintage 30. For clean sounds through the cab with a Fender amp the opposite is true. If I were playing through a Marshall amp I might feel differently because of that amps natural E.Q.. It is one of my favorite speakers.
