Peerless 830878 3-1/2" Passive Radiator
Peerless 830878 3-1/2" Passive Radiator is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Hot item!!This product without a doubt extends the bass response of 3" full range drivers.In my case, I used the Fountek FR89EX 3" Full Range - 8 ohm in a one liter sealed box, stuffed with real wool [no static drag on moving air]. The powerful neodymium magnet in the full range seems to control the radiator well. A 3-5/8" hole is all thats needed. I applied some dum dum putty on both baskets to prevent ringing. Have fun! I'll post pic's later.

Rated 5 out of 5 by from Beautiful PR, necessary for many micro designsThere are many small boxes where you simply could not get a port to work. I used this in a 1 liter box (Parts Express 0.04 cu ft knockdown) with a 3" Fountek full range, tuned to 60 Hz. A port would give you chuffing, but this beautiful unit produces a lot of bass. Surprisingly strong bass actually. THE KEY is: I used a MiniDSP 2x4 unit to boost 8dB at 60Hz and a sharp high-pass filter just below that point which is absolutely necessary. I also used the MiniDSP to EQ the driver and these things sound gorgeous.

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.

Peerless 830878 3-1/2" Passive Radiator

I am using 2 of the Hivi 3" B3N in a boom box that will be .263 cu. ft... I want to use these downward firing to help extend the low end, would this passive radiator work for my application?

Asked by: Jason Greene

Will these work with the TB W3-1335 SB? If so, what is the recommended box volume?

Asked by: Auburn81

As per design suggestion I'm using the tympany 3.5" drivers in a .21 cuft box. I can only place this radiator on top or bottom. The bottom will have about 1.25" of clearance as the enclosure has stubby legs.  I prefer to face it down. is that ok?

Asked by: Mikemk92
Yes this will work fine down firing with that much clearance.

Hi, will this PA work well with Fountek FE87? Recommended enclosure volumes, single / double PA, etc.

Asked by: inuro
Unfortunately these will not work together very well. The passive will tune too low to have useful bass output. These are much better in standard vented enclosures.

How is the peak vibration that this can handle? The xmas.

Asked by: ljk2000
Peerless does not specify Xmax for this passive, although it appears to be 4-5mm one way.

What are your thoughts on using the Peerless 830878 with the Dayton Audio RS100-4 in the Denovo Audio Knock-Down MDF 0.04 cu. ft boxes?  What would the box be tuned to?  Or should I use a port on the box?

Asked by: Jordan Reed
In that volume I would recommend staying sealed. Porting will offer better response than using a passive radiator, but the volume will need to be doubled in order to get a reasonable ported response.
