Tang Band W4-1879 4" Full Range Driver
Tang Band W4-1879 4" Full Range Driver is rated 5.0 out of 5 by 5.
Rated 5 out of 5 by from Single driver towersI bought these drivers to build some faceted towers that I had in mind. I hooked them up to my Marantz amp.and they sounded really sweet. Then I connected a valve amp to them and they are fantastic! The sound is defined, clear and easy to listen to. I am not able to measure them, but my ears tell me they are good. The TB's aren't cheap, but neither is the sound.

Rated 5 out of 5 by from Awsome THD plots (official, from TB)I'm still investigating this driver. It is really expensive but this distortion plot I got from TB looks truly awesome. Just like to share with everyone

Rated 5 out of 5 by from Great in a Transmission Line EnclosureWas attracted by its technical description and features and ordered a pair to try out. I decided to use a TL enclosure as I love the uncoloured sound this enclosure provides. It was suggested that a tweeter would improve the off axis response so I added a Vifa BC25SC15-04 1" Soft Dome Tweeter as I have these on hand. I just added a 2uF capacitor in series for for the tweeter. The result was excellent. One word of caution is that these speakers need at least 48 hours of breaking in. I was very disappointed during initial listening test. Initially the sound would distort when played loud but gradually distortion disappeared after breaking in. The speakers sound wonderful. The sound is crisp and clear with very good resolution and minimal distortion. The bass is also very clean with no coloration. Highly recommended.

Rated 5 out of 5 by from Amazing little driver!I bought a pair of these to install in my Frugel Horn Mk3 project. They sound great. Hard to believe they are only 4" drivers. Deep lows, smooth mids, silky highs. Being realistic, if you're into Dubstep, check out TC speakers. If you enjoy full range speakers, uncorrupted by crossovers, for critical listening, give these an audition.

Could i use this in a 2 way design with the tymphany NE225w 8" subwoofer? I would like to use this as a midwoofer/tweeter

Asked by: PleaseHelpme
I do not see any issue with that setup at all. It should work well in that application.

Apologies for my technical weakness... I'm trying to make a lusterous ceramic spherical enclosure for a quality full range speaker (to basically copy the design of a wine-named speaker). I imagine damping would be important. Good for this use?

Asked by: jerryfried
Damping would be recommended for a spherical enclosure housing a full range driver. This driver would work well for an application like this.

Could you suggest a port size if used with your cabinet TWC-0.38CH ? Thanks.

Asked by: Milty
Our part number 260-402 would be an ideal size for this combination. With no port modifications you will have a tuning frequency and F3 of 49 Hz.

What port size would work well for these in your 302-721 cabinets?

Asked by: misterBill
This cabinet is a bit large but it will work. I would recommend heavy fill with a 1-1/2" diameter, 2" long port for a tuning frequency of 50 Hz.

if there plots for off-axis response and THD ? Nothing comes back from Google search.

Asked by: gfyl
Unfortunately Tang Band does not provide off axis or distortion measurements for this driver.
