Rated 5 out of 5 by from Really improves small speaker low endI build a lot of small speaker projects and of course low end is where small speaker simply cannot go by adding one of these to certain enclosures you can add more bass and really improve the sound.

Will these work well with the AuraSound NS3-193-8A? If so, what configuration would you recommend?

Asked by: Tom_S

Hi Im planning on building my first portable speaker. Im planning to get 2 Peerless 830985 2-1/2" Full Range Woofer. would this passive radiator be ideal and how much volume is required for the enclosure? and how where would the radiator be placed?

Asked by: Ninjaplanker
You will get a much better response from the full range if you simply port the box. In 0.04 cubic feet, a 1/2" diameter, 2" long port will tune the box to 70 Hz. The Peerless PR will tune it closer to 50 Hz and you will lose a lot of the perceived output down low.

I have one pair of 830855:s and one pair of 830856:s lying around, brand new. I'm thinking about using these together with a couple of 830878. What would be a suitable enclosure volume for one driver together with one or two passives?

Asked by: Sam B
This passive will work with both of these relatively well. For the 830855 I would recommend .08 cubic feet total with two passives for a tuning frequency of about 60 Hz, no weight added. For the 830856 I would recommend .13 cubic feet total with two passives for a tuning frequency of 50 Hz, no weight added.

What will be the suitable parameter to look for while considering PR's? Like for vented enclosures, we can key in dia and program will tell the length. So for passives, what should I key in that will tell that this PR is suitable?

Asked by: arjunm009
There isn't a single parameter that will tell you whether a given driver will work well with a passive radiator. Usually drivers that are designed for very small vented enclosures will work with a PR, especially if the volume is too small for a port to be practical. In order to tell how well it will work with a given PR, a model will need to be done.

I would be very interested to know which programs I could use to tune(with great precision) the passive radiator with the enclosure. Help please ?

Asked by: Jaana
The program we sell that would work well for this is BassBox 6 Pro which you can see below.http://www.parts-express.com/bassbox-6-pro-software-cd-rom--500-923
