That requires T/S specs for the drivers in question.

If they exist Monoprice would have them. If they don't go elsewhere. It's not like you can't find plenty of drivers that do have specs posted.

I doubt they make them, so they may not have the specs. They should be able to get them from whomever they source the drivers from if they want to, but I guess as they already have your money that might not be high on their list of priorities. mad.gif

reply back from monoprice:


In regards to your inquiry, unfortunately we dont have a box size specification for our speakers as many of our customers install them with out a box and in rare occasions such as yours might need one. We would recommend that as long as you do have 1/2 clearance from side to side around the back of the speaker that would be enough clearance for the speaker to have proper sound. We have included speaker stats for the item PID 4103 and is in PDF format.


Bill, can I email you the speaker stats to see if you can understand them...I know I certainly don't

You'll get best results full range in a 1 cu ft (net of driver and duct) box with a 2" ID duct 2" long. Used with subs crossed over at 100hz use a 1/2 cu ft net sealed box.

Line it with an inch of polyester batting or open cell urethane foam. Stuffing is not required as the box Q is a perfect 0.7.
