Demented Posted August 28, 2001 Share Posted August 28, 2001 I have a pair of old epic cf-2's that I dearly love and would like to bring some new life too. Recently I added a subwoofer and was wondering if my cf-2's would benefit form sealing the front port on the bottom (single port on my cf-2). Basically turning it into a sealed system. Or if there are any upgrades I do (crossover, speakers, etc). If not I am afraid my quest for audio enlightment will retire my cf-2's into the basement.

JohnA Posted August 28, 2001 Share Posted August 28, 2001 Plugging the port will not damage anything and will reduce the bass output near the port's resonance. It might even increase the output at deeper frequencies, slightly. Try it. I've never seen a CF-2, so I don't know what else might be done.

rowooo Posted August 30, 2001 Share Posted August 30, 2001 Old???? Come on, they were last made in 96...What kind of equipment are you using? What about your speaker placement? There were three versions of the CF-2's. I know the third version had quite a shorter port than the previous editions, along with a couple other minor changes. What is it about the sound now that is lacking in your opinion? I've always enjoyed my pair and with some recent upgrading of cables and etc, they will never leave my house...Let me know....

Guest BobG Posted August 30, 2001 Share Posted August 30, 2001 You will not harm the CF-2's by plugging the ports. It will certainly change the sound in the low bass. Plugging ports will change the tuning of the low freqency system, making it further from the intended performance. Why not just run the CF-2's from the sub high pass out? That would likely yield more accurate results. No harm in trying the experiment. If you like the results, you can keep the plugs and if you later change your mind it should be easy to reverse.

Mike Lindsey Posted August 30, 2001 Share Posted August 30, 2001 BobG, I have a pair of CF-2's and am not quite sure what you are saying by "Why not just run the CF-2's from the sub high pass out?"
