Product Details

6-1/2" Poly Cone Midbass Woofer 4 Ohm

This durable 6-1/2" poly cone woofer with rubber surround is designed to work best in small, sealed bookshelf-style cabinets. The damped poly cone creates smooth sound from 45 Hz all the way up to 3,000 Hz and is easy to integrate with many different tweeters, and the 4 ohm impedance extracts more current from an amplifier for twice the output (3 dB increase), when compared to a similar 8 ohm speaker.

A 1" voice coil is combined with an aluminum former for a power handling rating of 30 watts RMS and 60 watts max, and the "Q" of the motor is such that solid bass performance can be achieved in cabinets as small as 0.25 cubic feet, with an f3 of 63 Hz (with a 1/4 pound of acoustic fill).

Save over 50% off the original price through this exclusive factory buyout.

6-1/2" Poly Cone Midbass Woofer 4 Ohm
6-1/2" Poly Cone Midbass Woofer 4 Ohm is rated 4.4375 out of 5 by 32.
Rated 4 out of 5 by from nice little speakergot a couple to reload so old scottts enclosures..cant go wrong for the money..this was a sealed box design..sound just fine

Rated 4 out of 5 by from Well Worth it!Bought 2 of these last week and installed them into my 2002 Dodge Ram front doors as components (with adapter plates). I already had Jensen JXR235 tweeters in the dash. These Midranges make a nice compliment to the overall sound...MUCH better than the cheap 6x9's I had in there. It was necessary to adjust my passive equalizer UP on the 60 and 150 Hz, as these are run thru an amp. Also adjusted the 400 Hz, 1 KHz, and 3 KHz DOWN to make a nice flat sound for these speakers. Works very well for rock, country, jazz, and classical. Don't know about electronica or hip-hop though. I highly recommend these for good sound. They aren't high end car speakers, but work great for the cost. Very satisfied customer.

Rated 5 out of 5 by from Very good for a budget-conscious sealed speakerI've paired these inexpensive woofers with Visaton polycarbonate tweeters as a challenge to see how much can be achieved for little $$$, using a set of Baby Advent II cabinets. Mission accomplished, I'd say!They are performing extremely admirably as we watch an NFL television broadcast. Play-by-play announcing above crowd noise is robust and perfectly intelligible. Bass in this .33 cu ft, heavily stuffed sealed cabinet is absent of any rude, boomy peaks and extends lower than I had expected. Higher frequencies transition smoothly into the tweeter's range. Easily, money well spent.

Rated 2 out of 5 by from works well from 80hz to 4k hzbought 24 of this speaker to attempt a party tailgate project on the rear doors of my suburban - un fortunately i have not found a way to keep them from sounding distorted and un happy below 80hz - if i had known this i might of went with 8" size speakers instead but luckly i can just tune my crossover network to drop like a rock at 80hz and let them play with a mild slope in the upper range starting at 4k ish. ended up using 9 on each rear door sealed in stereo left and right - will post a pic when finished i hope it works out better than my test bench enclosures ive tried them in

Rated 5 out of 5 by from You won't do better for $5Bought a pair of these to use in an old pair of Zenith Omnidirectional speakers. First off thanks PE as always for accurate info, these were the exact dimensions noted and thus fit my project perfectly. I mounted some 1/2" Tang Band tweeters on a thin aluminum rod in the center of these firing up through a new grille into the diffuser, simple first order XO at 5k. Sound much better than they should, very impressed with how clean they are crossed this high, I know that if they weren't in an omni it might be a different story on axis, but the bass and mid bass is quality as well for such a cheap driver. Highly recommended!

6-1/2" Poly Cone Midbass Woofer 4 Ohm

Any point in considering these for open baffle? Fairly high Q, and efficiency. Thinking of stringing up to 4 of these for each channel -- target load being 4 ohms, band passing them around 60Hz, and high passing the full range driver at 200Hz.

Asked by: ibroke
These should work well open baffle, especially used in multiples and high passed at 60 Hz.

Sealed or Ported? Looking at building 4 speakers for about a 20'x30' room that will be in the corners of the shop. Would a ported or sealed configuration work better for this? All types of music, some is somewhat bass heavy like hip hop, techno, etc.

Asked by: xb2fergie
These woofers like a sealed enclosure, roughly 0.5 cubic feet each. Porting will give you a bloated bass sound and limit overall power handling.

9 of this speaker in sealed box final load of 4 ohms - shared air space - what should my cubic ft goal be to build to for strong response from 80hz and up ?  i hear shared enclosure of multiple woofer reacts diffrently than single ?

Asked by: brian84corvette
You will get the same extension with multiple woofers as you would with one, but your overall sensitivity will go up. The optimal volume for nine of these is almost 7 cubic feet, but if you are only interested in getting to about 80 Hz, you can cut this volume down significantly. Anything between 1.5 and 2 cubic feet will give you extension to 80 Hz, I would recommend heavy fill.

The product details say: "The damped poly cone creates smooth sound from 45 Hz all the way up to 3,000 Hz....." Yet the product specifications say 50 to 6000 Hz. Why the difference?

Asked by: HW13
The frequency response is based on the Fs of the driver as well as the upper limit before the response starts to droop. This has a very smooth response from Fs (52 Hz) up until 3kHz, where the response starts to encounter a breakup peak or null, and then finally starts rolling off naturally around 6kHz.
