Hi I am new to cabinet and speaker. I have a new DSL1c for bedroom playing. I am thinking to buy a 112 Cab. I have few questions. 1. Which cab do I get, open or closed back? I play both rock and blues. 2. Does cab size matter? Is bigger size better than smaller size? How is this one? https://www.amazon.ca/Seismic-Audio...id=1495251410&sr=8-15&keywords=guitar+cabinet 3. What speaker match DSL1 better? Celestion Vintage 30 or Eminence Cannabis Rex? https://www.amazon.ca/Eminence-CANN...5251589&sr=8-1&keywords=Eminence+Cannabis+Rex Thanks for your help. I appreciate it.
