DDCX Coaxial Speakers enclosure info:
Our coaxial speakers are designed to give excellent bass response from the midrange/midbass driver as compared to most offerings out there in an affordable package. They are at home in a stock door or rear deck speaker location but will really show their steel if you mount them in an appropriately sized enclosure. A sealed or ported enclosure of the correct size will absolutely embarrass an infinite baffle/stock door mount. Below are listings of some good size enclosures, should the chance arise that you may put an enclosure in place of the stock locations. Note: If you shoehorn a speaker into a really small sealed enclosure, the lower bass response will suffer if the speaker has any efficiency worth mentioning.
DDCX-6x9s
work well in infinite baffle (IB) setups as well as a sealed box of roughly .3 cubic foot and up. If you find the space to build a vented enclosure for your 6x9, it should be between .5 and .85 cubic foot. Use our porting charts in the enclosures section; if you want to tune higher than 40Hz, simply cut down the vent length to your desired response.
DDCX-5x7s
work fine in IB setups also and a sealed box of roughly .2 cubic foot and up. If you have the volume required to build a vented enclosure for your 5x7, it should be between .3 and .5 cubic foot.
DDCX-6.5s
do well in IB installs, and in a sealed box of roughly .2 cubic foot and up. If you find the space to build a vented enclosure for your 6.5, it should be between .3 and .5 cubic foot.
DDCX-5.2s
are at home in IB applications and in sealed boxes of roughly .125 cubic foot and up. If you find the room to build a vented enclosure for your 5.2, it should be between .2 and .4 cubic foot.
DDCX-4s
do not mind IB setups but love sealed boxes of .1 cubic foot and up. If a vented box is possible, go with .15 thru .25 cubic foot.
The bigger the enclosure (within recommended specs), the better low frequency response you will have. Ultimate power handling is opposite in that it goes down as box volume goes up. To find out how much mechanical power handling your coaxial set has in its specific enclosure/application, you simply turn up the system to the point of barely audible distortion and back it down a tad. If your amplifier has a clipping indicator on it, this can help make the test quicker and more simple
