Product Details

A shorting ring on the polepiece is responsible for the speaker's extremely low levels of second and third order harmonic distortion. This impressive motor is coupled to an optimized paper cone with rubber surround, supported by a cast aluminum frame.

Tang Band W4-1720 4" Underhung Midbass Driver
Tang Band W4-1720 4" Underhung Midbass Driver is rated 4.8571 out of 5 by 14.
Rated 5 out of 5 by from Incredible sound!Paired this with a Dayton silk dome tweeter. Crossed at 2,500 Hz. Sound was unbelievable...I pushed it too hard and blew it. Already ordered the replacement. These are awesome drivers!

Rated 5 out of 5 by from Does what no other driver canIn ~0.25 cubic foot tuned to 55Hz, this driver gets down into the 40's! Not only does it get there, but it sounds very good up to the 2500Hz crossover point I selected. After modeling a slew of small drivers based on their T/S parameters, I'm confident that there is not a better driver for (almost) full range near field monitors in such small cabinets. Yes, they have their limitations but I'm sure there are many people like me that want a nice sounding desktop system while in the office for near-field listening. They handle enough power to get too loud for me to listen to at a seating location 2.5 feet away. While the driver could easily cross higher, I chose 2.5kHz since the listening position is close and I wanted to reduce error. I did try a 2nd order crossover and didn't like it as much as LR4 but the XT25 tweeter I'm using doesn't have the best performance down low. I personally feel like a dedicated subwoofer would be detrimental for music listening unless you regularly listen to pipe organs, use these in a big room or just want to play loud. Having used many >$200/piece mid-bass drivers, this little 4" driver for around $50 did more than surprise me. The midrange performance is top notch.

Rated 5 out of 5 by from Great driver, clean, fullVery clean mids and a surprising amount of low end extension. Super beefy motor and overall very well made. Check the voice coil leads as they may be close enough to the spider that they could slap at full extension, but just move them a bit and you're fine. At the sale price, I don't think there's a 4" driver that can touch it in performance.

Rated 5 out of 5 by from Drop-in replacement driver for 5" Bazooka tubesI used these to replace blown drivers in some old 5" Bazooka vented tubes (discontinued long ago). They were literally a drop-in replacement with the mounting holes even lining up. No modification required to the driver or enclosure.They're probably too low Q for the enclosure, but this driver gave those old tubes a new life, and I was able to enjoy bass in my car again.

Rated 5 out of 5 by from Nice replacement for TEAC LX-600 midbass speakerPurchased a "new" and "unopened" pair of TEAC LX-600 indoor/outdoor speakers on eBay. They arrived, opened of course, with one speaker blown.Got these as replacements and they dropped right in and sound really, really good. They do not disappoint. Very impressed with the sound quality even the lower bass reproduction.Very nicely done.

Rated 4 out of 5 by from Rich Bass From a Small BoxOne of the best small mid-basses out there. Can get down to the 50's in less than 6 liters! Smooth silky midrange. Though rated as 4 Ohm, I'd probably consider it a 6-8 ohm driver for amp loading purposes. Not high on sensitivity or capable of high volumes when used as a woofer. Sonic quality is up there with "high end" brands
