Rated 5 out of 5 by from Tang Band speakersEverything about the experience was excellent. Good site, reviews, checking out, shipping and then excellent speakers at a low price. thank you

Rated 5 out of 5 by from Fantastic little speakerI used 4 of these little babies (2 x 2) in some funky PVC towers I built from commonly available plumbing fittings. A powered sub with speaker level out is the active crossover, no other electronics. Driving the PVC tubes with a Lepai 2020 amp. The sound is as good as it can get. Clarity, detail, volume - these speakers have it all. For adjusting to room acoustics, the I kept the direction adjustable through 360 deg. Very happy with the result.

Rated 5 out of 5 by from Good FullRangeLooks Good, Sounds Good, I'll buy another one.This is my 2nd hand made speaker. Loving it.

Rated 5 out of 5 by from Superb PerformanceI used these units as a replacement for a discontinued Tang Band driver in a pair of self-built "nanotower" single-driver, ported speakers. The clarity, imaging, transparency and satisfying bass that this little driver produces in this design are astonishing. I'm also impressed with the great support I got from Parts Express. The phone rep plugged my cabinet specs and this driver into his design package and was able to give me the "thumbs up" on the substitution. Great little driver!The attached video, showing the speakers on a covered deck, really cannot capture how good the sound is.

Rated 5 out of 5 by from nice upgradeI used these to replace the drivers in an old set of Harmon Kardon HK195 computer speakers. I was pleasantly surprised by them...in the HK195 enclosure using the HK195 built-in amp they sound better than my Bose Mediamate's! In fact, so much so, that I am now making a set of my own cabinets to house a pair of these with a Dayton DTA-2 amplifier module.If you're interested, the volume of the HK195's is approximately 1.5ltr's so that's what these handmade cabinets will be.

Rated 5 out of 5 by from Klipsch 2.1 ResurrectionLike countless others, I've fallen victim to a failed Klipsch ProMedia 2.1 system - dead channel and subsequently blown driver.* perfect fit, just bend the connectors accordingly and use the existing hardware* excellent sound, tons of mid range that never before existed with a far cleaner sound than the OEM Klipsch drivers* would certainly reco a swap even if both your drivers are still working as these are far superior to the factory speakers, great stuff

Tang Band W3-881SJ 3" Cast Frame Neodymium Driver

Can 2 of these be used in an MTM configuration without causing any nulls, imaging problems or other negative effects compared to using one driver? How much would it increase the sensitivity (86 to 89?)

Asked by: nikko
Two of these wired in parallel will increase sensitivity by 6 dB. Two drivers stack on top of each other will limit vertical dispersion but will not affect off axis response very much.

I want to run this full range in portable speaker box and was thinking of adding a high pass filter. Should it be 80Hz or 100Hz. I would like to get as much bass as possible from this but I don't know if 80Hz is too low, will it distort at high volumes? 

Asked by: JadH
This driver will have excursion problems regardless of the high pass setting. In a Bass Box model assuming an optimal volume, excursion is reached at 250 Hz with only 5 watts. This will make a great midrange but it is not intended for bass output. I would recommend something like the Dayton ND90 instead.

the ported size is listed at 0.18ft^3 @ 64Hz. What port dia and length would that be? Also, is the photo out-dated? Description says it has a black phase plug. It looks like a normal dust cap to me. thx

Asked by: avc77036
The port size for this driver would need to be 1" in diameter and 1-1/2" long for an F3 of 63 Hz. The photo is accurate, I do not see where a phase plug is mentioned.

Please confirm the overall outside diameter. The TB specs are contradictory and I doubt that the 3.19" listed here is correct.

Asked by: DCF848484
You are correct, the actual diameter of this driver frame is 3.66". I will have the website fixed.

Surround speakers?

Will these make good rear and side surrounds or do I need to pair them with some tweeters?Thanks.
Asked by: sem613
For most applications these will work fine by themselves, whether they require a tweeter or not is up to you in the long run.

Is this Tang Band W3-881SJ ever going to be available? The due date just keeps sliding.

Asked by: aamesa
I am a customer like you and do not work for PE. My assumption is that because this Tang is such a great speaker and value (read the reviews) it is in demand and perhaps on a buy list. I would place an order and get your place on the list.
