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 4.5 out of 5 by 18.
Rated 5 out of 5 by from price can't be beatThese are unbeatable for the price. 5 bucks for a 6.5" woofer, how can you go wrong? I have put these in multiple vehicles and they have always sounded great for the casual listener. I believe they are also the same woofers that are used in the Dayton B652 bookshelf speakers, and lots of people (myself included) think they sound fantastic for the price. If you need cheap 6.5s as a replacement speaker or for a budget build, don't even think twice about these, just hit the add to cart button.

Rated 5 out of 5 by from Unbelievable valueI build custom boom boxes and took a chance with these as I was given a very tightbudget. I have used more expensive 5 1/2 inch mids or woofers in other projects that cost 5 X as much as these. I will have to say and I blown away about how muchthese speakers rock. Running them off of a Lepai 2020A and matched with Hiwave BMR12 Full Range. I highly recommend them for smaller applications and the Lepaipushes them perfectly. I will buy more when they come back in stock. Pics of project below...

Rated 5 out of 5 by from good bang for the buckBought 2 to replace in an existing bookshelf speaker set. Sound excellent. Can't beat the price.

Rated 5 out of 5 by from Awesome performance/value!I picked up 4 of these back when I first saw them as buyouts just to try some experimental enclosures. Two of them in a giant folded horn sub enclosure shakes my house at less that 10 volts with the drivers wired in series. Holy cow! Nobody can believe it's just two tiny 6 1/2" woofers. I bought a bunch more for some line array and bookshelf designs. Excellent performance/value in the right applications.

Rated 4 out of 5 by from a steal @ this price!Got four of these just to see how they sounded. Also my order was just below the threshold for free shipping. Two ended up in the back doors of my bosses crew cab the other two replaced woofers in some Allison Acoustic AL100s that I had rescued from a thrift store. One of these still had the original woofer intact when I got it several years ago, but had recently lost the foam surround. If I recall correctly the cabinets were .35 cu.ft. and were stuffed with .38# of poly. With the exception of the poly cone and the lack of a bumped back-plate these look and sound very similar to the original woofer. Sensitivity seems down a little compared to the coated paper original but still blends nicely with the tweeter. These are just crossed with a cap on the tweeter. These do sound much better than the R.S./Pioneer 6 1/2 " someone had put in one of the cabinets before I got them. The bass is ok, but I appreciate having the sub hooked up with these. Mid-bass and mid-range sound faster and have more impact than I usually hear from a 6 1/2" driver. (If the bass is taken care of elsewhere I tend to like 5" mid-bass.) Overall I am impressed with these especially @ the buyout price. I bought 26 more for a line array project!

Rated 5 out of 5 by from Great Mid-woofer, exceptional voice qualityI found a pair of Polk Audio floor standing cabinets and needed 6 1/2" drivers, these mid-woofers fit perfectly, and matched with 3" Sony full range, 1" vc, speakers the floor standing speaker sounds like a big midrange no lows, and no real high frequency. But was able to elimanate any crossover at all. Wired in series and sony in parallel little less than 4ohm load. For a normal 5.1 home theater audio/video reciever with only one pair of front speakers the amplifier was fine with this low load. Overall for the money they absolutely were excellent.

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

just bought 8 of these ,front stage(4 per side)paired with the jamo tweets on buyout.

whats a good size box to mount on wall for 4 and maybe 2 just in case i feel 4 per side is over kill...?first project....
Asked by: justmaleo
With a Qts that high I would say .25-.5 cubic feet per woofer sealed with heavy stuffing. These will play relatively well down to about 70 Hz so they would need to be mated with a sub for home theater duty.

This woofer in a 6 driver setup

Hello, I am thinking of going with a 6 driver setup for my two mains. Would this woofer be ok for this setup, I really like the looks of the mulit. driver speakers setup, I would also include a tweeter for the highs. Would I be better just building a 2 way bad with 1 or 2 better drivers?
Asked by: Mlt2
Six of these drivers will certainly get loud but they will only work well in a heavily stuffed sealed enclosure which will limit low end extension. A simply two driver 2-way will sound similar but not have anywhere near the dynamic or output capabilities.

Can this be a replacement woofer for the Dayton Audio B652 6-1/2 Bookshelf Speaker? http://www.parts-express.com/dayton-audio-b652-6-1-2-2-way-bookshelf-speaker-pair--300-652

Asked by: rws79
This will work as a replacement although this will create a 4 ohm load which is not safe for most home stereos.

whats the correct wattage?

In the specs for this speaker it say it is rated at 50W rms and 100W max but in the image it shows as only 30W. I know that usually when a mark on a speaker says (30W) that is typically the max handling power. So is the picture wrong? Or is this a misprint? Or is the actual item different from the picture? I added YOUR picture from the add.
Asked by: snaggndragon
This woofer is rated for 30 watts RMS. We will update the specs on the website.

Good in-wall speaker?

It looks like the larger sealed airspace the better, so... wouldn't this speaker do well in-wall using the air space between studs?
Asked by: Mightymosquito
Bigger is better up to a point--then it thinks it is in open space--[no baffle]. That being said, I have has good success with this application. Remember, the walls also have side and/or angled braces which make the opening smaller so this won't act "open". Also the wall itself will act as a boundary to increase the efficiency.
