Product Details

Tang Band W5-1685 5" Underhung Midbass Driver

The W5-1685 5" midbass features a long throw, underhung 1-1/2" voice coil driven by a massive 33 oz. ferrite magnet. 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. The driver's naturally high and smooth upper frequency rolloff facilitates simplified crossover designs.

Tang Band W5-1685 5" Underhung Midbass Driver
Tang Band W5-1685 5" Underhung Midbass Driver is rated 3.8 out of 5 by 5.
Rated 5 out of 5 by from Prodigious Bass for a Compact 10 Liters 2-wayWhen I decided to purchase this driver, I was hoping it will produce enough bass in a relatively small 2-way without me having to apply any EQ to boost the bass.After deriving the T/S parameters with LMS, I housed the drivers in a 10 Liters Sealed Box for testing.I was absolutely stunned by what I heard. The amount of bass is astonishing, especially for a 5" driver. No need for Bass Reflex, Horns or Transmission Line designs. Just a simple Sealed Box. Best of all, the flat response of this midbass driver contributed greatly to an issue free crossover to a Seas 27TBFC/G tweeter. Crossover frequency is 2KHz (active 18dB/oct for High and Low Pass).However, to use this W5-1685 to it's full potential, an accurate Thiele & Small Parameters is essential. My measurements with LMS vary greatly from the manufacturer's. I can only speculate that they made some changes after the initial measurements were made.Below are the basic t/s parameters needed for Box Modeling. Measurements made with LMS (Delta Mass method).Fs = 54HzVas = 7.9 LitersQes = 1.0Qts = 0.8The full T/S can be seen in the attachment. Measurments were taken after a 48 hour break-in with the W5. Signal Input at 2V with 30 grams of added mass.With an EBP of 54, I decided on a Sealed Box of 10 Liters. System Q is 1.070. This results in a slight 2dB bump in the midbass region which I prefer. The W5 will work equally well in a 30-35 Liters 2-way sealed box tower. At these larger volumes, Q is about 0.9. The W5 is very flexible in a Sealed Box design. Any volume from 10 Liters to even 50 Liters will work.

Rated 2 out of 5 by from Not as specifiedIt is a nice looking driver. However, I was depending on the Qts to be as advertised and it is not. The listed Qts is excellent for vented systems whereas my measured Qts of .62 is not. By cutting away about half of the spider I have the Qts down to .53, more usable but not at all optimal.

Rated 3 out of 5 by from You Get What You Pay ForRequires a rather large enclosure before it can achieve good bass extension... approximately .75 cubic feet per driver. Mid-range performance is about average and a tad on the weak side. The exceptionally heavy weight of this driver pretty much requires that they be mounted using T-nuts. The mounting holes in the frame also need to be a bit larger... I had to drill out the frames on mine in order to fit normal sized mounting bolts through them. Driver has a slightly high Qts for use in ported boxes... so a 0.5 cu. ft. aperiodic enclosure (aka "Variovent") might be a better choice. Overall, it's like what the heading says: you get what you pay for. In this price range, these are decent drivers... but you can do better with Peerless, Vifa, Seas or HiVi drivers for the same amount of money.

Rated 4 out of 5 by from Hard to believe what this driver can do...Capable of smooth articulate response from the 40's to 3000. Heavy, one of the few smaller drivers I would actually use hurricane nuts to mount. A lot of bass from a small box. Not quite a 5" ScanSpeak but pretty close. Recent price hikes, have knocked it down on the value chart for me.

Rated 5 out of 5 by from Absolutely stunning driverI used this with a Vifa titanium dome tweeter crossed over LR2 at 3.5khz. The sound of this driver is amazing. Very very low distortion, very flat to 6khz, and great bass extension down to 50 Hz. This driver is perfect for a two-way bookshelf system. It is attractive as well. One of the coolest things about this driver is that it can actually handle a decent amount of power. It has a vented voice coil and 6mm Xmax, which lets it get up into the 32 watt range at the low end without distorting. I haven't seen another 5" driver that can touch that.
