I've got a pair of 21" drivers looking for a home. I'm thinking about building 2 single 21" cabinets that have a space to mount a regular rack-mount amp in a separate chamber with front and rear venting. The amp would be completely enclosed, untouchable by the crowd. I'm thinking of using a CE4000 since they are cheap and sound really good on subs. It would be bridged into 8 ohms providing 2400 watts to the driver. It also has HP/LP filters built in. The issue I'm having is how to have access to the gain pot.
Would you miss having an accessible gain knob? I would be using these with a pair of HPR153's pretty much all the time so I think that I would be able to gain match the tops to the subs which means that I don't really need a knob on the sub, but I'm just wondering if you might think it would be a problem down the road.
BTW, using these amps bridged into 8, means if one of them lets the smoke out I can open up the other amp and drive the dead cabinet from the good one. Gives me a bit of redundancy which most powered speakers don't have. I plan on having either a door or a vent panel on the back that can be opened up with tools if needed, but the intended SOP for these subs is to plug in power and signal and go.
Any thoughts?
