replacing port with PR opinions please!

crippledchicken · 1st October 2007, 10:40 PM

i am running the Dayton 15" DVC in a 4.8 cu ft well braced enclosure with a full length 4" dual flared Precision port (17") length i think. since this enclosure is on the small side anyway, could i maybe gain some performance using the Dayton 15" PR instead of using the port for tuning? if so, any reccomendations on a good tuning point and, about how many grams of weight i would need to add to the PR? as i've never used one before Thanks for any advice!

Probably not if you don't notice any vent 'chuffing'. Frankly, at this acoustically small size I'd experiment with damping the vent or even turning it into a sealed alignment.

PRs work best on cabs that calc a silly long/large vent to get a low vent mach.

hi and thanks GM! I notice no chuffing especially, with the bottom mounted vent. I will try your suggestions and see how they turn out!
