Can a T-amp power a tekton 4.1 or 4.5? I'm interested in the speaker if this cheap amp can power it nicely. But I noticed the power rating on the TA2024 is very low. Is the 2020 better? The 4.1 driver is rated 15W and the 4.5 is rated 45W, more interested in the 4.5 as the frequency response extends lower.
