Welcome to the SMD forum!
Total noob question. I would like to know if there are specific amps that are better at playing lower bass notes than others? I have a sa 12 rev. 3 D4. And I am interested in a rp2000.1d. I read a review that said it sucks at low frequencies. I was under the assumption that only the box affected this. Anyway, if anyone could enlighten me it would be greatly appreciated.
