Product Details

Tang Band W4-992C 4" Subwoofer 2 Ohm

Tang Band designed the unique W4-992C 4", 2 ohm subwoofer speaker to provide excellent bass response in a small package. While it may look similar to the other 4" drivers, the cone, voice coil, surround, and motor have been optimized for higher-power bass applications. High power tinsel leads and venting under the spider yield maximum thermal capacity. At the same time, a heavy-duty paper cone, rigid dustcap, and twin-roll surround allow linear and distortion-free cone movement.

This subwoofer is great for mini 2.5 or 3-way speakers, a 2-way design with a robust tweeter, and as a miniature computer subwoofer. The 2 ohm impedance allows for a wide array of wiring configurations: wire four in series for an 8 ohm load, eight in series-parallel for a 4 ohm load for maximum bass in minimum space. Perfect for modern audio applications, such as a subwoofer speaker bar to suppliment the bass in thinner sound bars.

Rated 5 out of 5 by from Excellent Driver!This driver supported all of the requirements. Low tuning frequency in a large enclosure really brought out the best in these.I wired 4 in series up to a Lepai 2.1 amp(2x40W, 1x68W) and it rocked the lower end better than the high-ends. It was a bit over kill to have four of these but it is a beautiful change in pace from the large sub-woofers usually seen in cabinets.The only difficulty I had was cutting the holes for these to slide into. After I asked a question on this page after I was unsure. It was answered with the reassurance that it indeed was, "3 1/2" inches. Let me tell you, I measured not only twice and cut once but I even bought the Jasper Jig and cut a perfect 3 1/2" hole. Only to be greeted by an opening too small. I measured again, and it was 3 1/2" on the dot. It's kind of hard to make a High Fidelity system when 4 out of 8 circle cuts are cut with a jigsaw. I was very disappointed in the lack of drawings and technical drawings for this driver. It ended up delaying my project a day behind, and it was pushed to the next weekend.I ended up cutting a hole 3 5/8" and the driver fit snug in place. I almost didn't have to screw it in! Love the product and the project came out great!

Rated 5 out of 5 by from Very tight bassThese are great little speakers, I also have the larger 5inch version that PE had on buyout a while back. Don’t let the size fool you they will hit; I have 4 wired in parallel and they don’t disappoint!

Tang Band W4-992C 4" Subwoofer 2 Ohm

Follow up question- I made in MDF 5/8 thickness. Box size is W 5 1/2 X H 12 X D 10  Vent is 5 1/2 inches wide 8 1/2 long. The model I chose seemed to have a 4 1/2 inch wide vent 8 inches long. Will this change the tuning significantly?

I wired the Tang Bands in series with a low pass filter 225 hz. I did not realize I had bought 8 Ohm filter. I read that using as a 4 Ohm low pass will bring it down to 112hz range. The full range side has 4 Ohm 300 high pass filter. Is this a problem?

Can you recommend box and port size for 3 of these?

Asked by: Reub82
I would recommend 0.4 cubic feet with a 2" diameter, 8" long port for a tuning frequency of 50 Hz.

I bought this driver to put in a vented box. I wired two in a series with a Dayton Audio Low Pass filter. My question is....When adding foam to the interior of the box. Where should I place the foam?In the large chamber on all sides. Foam in the vent too?

Asked by: Edwaux
Speaker cabinet foam should be placed on the cabinet walls, but not in the vent. Foam in the vent will alter the enclosure tuning and decrease the port output. It is not essential to put foam on the back side of the driver baffle.

For 2 of these drivers you recommended .29 cubic feet with a single 2" diameter 8" long port for a tuning frequency of 59hz.  If I were to use two ports 2" diameter 4" long would I get the same tuning frequency?

Asked by: bigurn
No, your tuning frequency would actually go up to 101 Hz with this alignment. In order to have two of the same diameter port tubes, they would have to be 18" long each for the same tuning frequency. You could use two 1" diameter ports at 4" for a tuning frequency of 57 Hz however.
