D130

[jackrhein]

i am using a D130 for a guitar speaker and i am using an open back cabinet. I love the sound but i am not getting enough bass response. Would i get more bass if i used a closed back?

Open backs are generally good to around 90Hz. A closed back (but bigger cabinet), or a ported cabinet will go down lower.

Not only will it go lower in a closed cabinet, but it will be much tighter too...though it will be more directional from the upper mids on up.
