what specs would i need to give you, for you to be able to tell me what size enclosure and port size i need?
Rarely. Some of the car audio drivers will give examples that work great in a car. Very few will provide details like Exodus Audio used to - http://www.diycable.com/main/pdf/M21-1.pdfMr645 said:Start with the driver. The manufacturer will have specs as to what size and type enclosure will deliver different results.
Excursion is how far the cone moves each direction. Watch the cone in this video move more than 1 inch in each direction - That's a sub. Your woofers move about 1/8" each way. They are not designed to play extremely low frequencies like a subs are.boss hawg said:i do understand your point about the excursion. i'm just having fun with my experiment. but, back to the original question. i guess i should build a box equal to the enclosures that the woofers were in originally.
Without knowing the Theile/Small parameters of the drivers there is no predicting the response.i'd like to tune it flat
A 5.5 inch port gives you a tuning frequency around 26 hertz. That's not bad. As long as you NEVER feed a signal to them with a frequency lower than 26hz and you don't overpower them, it should be OK.build a 6 cu. ft. enclosure for the two woofers. ..... you think a 4'' in. port 5.5 or 5.25 in. will do ok?
