with this PR - http://www.parts-express.com/peerless-830878-3-1-2-passive-radiator--264-1060 - can the box be made smaller? what would be the dimensions then possible. or any other PR?

Asked by: arjunm009
This driver will work well in an enclosure that measures 7"H x 4"W x 3"D with the Peerless passive radiator and no weight added. The box will be tuned to about 70 Hz.

Using two of these in a single box, is series or parallel preferable? With my amplification I can go either way. Thanks-

Asked by: MrSteve
Parallel is usually a favorite as long as the amplifier can handle a 4 ohm load. This will boost your sensitivity by about 6 dB overall.

I plan on using four (4) of these in a sealed box from 150 hz up (6db high and low pass filter) wired in series parallel. Any suggestions on internal volume? Thanks, Steve-

Asked by: MrSteve
A volume of 0.09 cubic feet for all four will work well and start a natural roll off at about 150 Hz.

Vented Box Suggested Size

I really appreciate the suggested enclosure sizes, but could you please confirm the vented box information?"Type: Bass reflex; Size (internal) including volume displaced by driver and port: 0.12 ft³; Internal cabinet dimensions (golden ratio): 7-3/4"H x 4-3/4"W x 3"D; Port dimensions (with flared exit): 1" dia. x 6"L"With the box dimensions listed, I'm only getting a volume of ~.06 cu. ft., but the paragraph lists a recommended internal volume of .12 cu. ft.Am I off, or is one of those is off? Does it affect the port size, as well?
Asked by: m.a.x
After running a quick model, the volume of 0.12 is actually wrong and the dimensions are correct. The vlume for this driver needs to be 0.06 cubic feet. The port is the same size.

I can't seem to import the frd and zma files into Passive Crossover Designer. Do I need to modify these files?

The frd and zma files are in a different format than I've used in the past.
Asked by: Skiman
When you download the files you have to extract them in order to modify the text. Once you do this, open them in Notepad and delete everything but the three columns of information which are Frequency, Phase and Amplitude. Save the file after it is modified and you should be able to load them into PCD without issue.
