Question about Wharfedale Modus One-Six Speaker

4 Answers

Wharfedale Modus One

Tweeters are not functioning on both of my speakers.. haven't attempted to disassemble yet.. located replacement NEW tweeters directly from Wharfedale, but before I purchase them.. wondering if its more likely that my crossovers are blown and how can I test that.. I assume I can just provide a signal to the tweeters to determine if the speakers are operational. Any direction or advice appreciated. Thanks JOHN

The tweeters are probably blown, i had the same problem.
You can test this by placing the cable on the dismanteled crossover at the back of the speaker. colour blue/yellow.
No high volume please.
See http://www.hometheatershack.com/forums/diy-speakers/4549-wharfedale-modus-one-six-crossover-pics.html
for pictures.
If the tweeter is blown it can be dismanteld with the aid of a screwdriver, horizontally.
Place it between the tweeterbowl and the ring which has the mark wharfedale on it. The tweeter comes loose. On second hand sites you can buy little speakers, like modus one or two's with the same tweeters for a good price and put them on your larger speakers.

This how i repaired 2 of my 4 modus eights.

good luck Danny Mol

I recently lost my tweeter on Modus One Six. During hi power play back, I hear occasional clicks and pops. I emailed the manufacture and got no response from IAG nor Wharfedale UK. So I managed to fix it myself. After switching the tweeters to the working speaker (turn the tweeter housing to align with wharfedale signature and insert a flat head screw driver with cloth wrapped around its head and pop it slowly.), I was able to determine the tweeter itself is not broken, so that leaves us the cross overs.

Modus One Six has the crossover right behind the back plate terminals. unscrew 4 wood crews, and there you have it.

the tweeter uses 335K/100V capacitor and 3 watt/1 Ohm resistor.

335K is EIA Coding The EIA code works on a very similar principle to the resistor colour code. The first two digits refer to the value with the third being the multiplier. The fourth character represents the tolerance.
When the EIA code is used, the value will always be in Pico-Farads (see Decimal Multipliers).

Example 103K
This expands to:
1 = 1
0 = 0
3 = x 1,000
K = 10% (sec Capacitor Tolerance for listings)
Then we combine these numbers together:
1 0 x 1 000 = 10 000pF = 0.01µF, = 10n ±10% tolerance

Example 335K
This expands to:
3 = 3
3 = 3
E = x100,000
K = ±10%
Then we combine these numbers together
3 3 x100,000 = 3,300,000pF = 3,300nF = 3.3uF 10% tolerance.

so 3.3MFD(micro Farad)/ 100v elctrolytic, non-polarized capitor is what we need for the tweeter. That is 0.49 USD component in local Frys electronics.

The NTE brand capacitor appears a lot smaller compare to the original (see photo)
Cut off the original 335K 100V yellow capacitor and re-solder the new replacement, and voila!!

I get my sweet crisp tweeter sound back. pop in a "Lucia di Lammermoor" opera CD , and I am right back home!

    The photo shows a yellow normal capacitor but the replacement used is an Electrolytic Radial ?

Is the tweeter a stand alone 8 ohm speaker?


yes, but it is attached to circuitry that allows only the high frequecies into it. You can replace the speaker with any 8 ohm tweeter without any difficulty, but if there is a capacitor across or in series with the speaker, make sure you put it on you new speaker the same way.

Ok..... I have some Wharfedale Modus 8s. My question is, is that the base speaker is crackling a bit. typically when you don't have enough power the tweeters will clip first and go out. perhaps i did...


Dunno how old they are, but I just had an 11-year old pair of woofers re-edged because the foam surround and the adhesive had deteriorated. Upon close inspection the foam surround was noticeably pulled away from the cone in a few spots. Unfortunately, if there is an age-related issue with materials beneath the surface that you can't see, you'd have to pull the driver to check it out.

It wasn't until I turned my bass up loud that anything sounded wrong, which precipitated looking for the culprit (quickly found).

Can't get wharfedale melton 2 tweeter to work. Looked inside cabinet and need advice on internal wiring please. These are very old but one works perfectly and the 12'' bass driver on the problem speaker is...


The tweeter has burned out and cannot be salvaged. I also own a pair of (ex) Melton 2s. In the beginning Wharfedale were good at supplying spares (see www.wharfedale.co.uk for contact info and advice). A few years ago after my cat destroyed the 12 inch unit in one, i invested in new insides, including state of the art 12 inch woofers, 4 inch mid range and 1inch tweeters with a good 3 way crossover. The cabinet is great so consider asking a techie friend to do this for you. Please don't just cut out and connect to amp speaker wires! You will get terrible sound and risk ruining both amp and speakers! Best regards Karl (karl@simpson.nom.fr)

Quite new speakers 9.1 but the sound is very dull - sounds like tweeters are not working can these be repaired


You didn't answer if they ever worked right.

One doesn't usually judge tweeter function visually. They don't actually move much.

Take a cylindrical tube (like from a paper towel) and place it over the tweeter to isolate it from the room sound and the woofer, then place your ear at the other end. Anything? Nothing?

What sort of signal are you feeding them? Let's look (or listen) to the source and how its audio gets to the speakers. Define the electronics, pathing and setup.

Maybe some history. Have you ever tried to blow them up in your enthusiasm for the new rig? If the tweeters are dead, that may have happened. Microphone use and feedback = dead tweeters.

Hello georgesverme,

I'd recommend starting with the local importer of Wharfdale products to see if they have exact replacement tweeters for sale. Contact:
Bob Springston, Sound Import, LLC
Phone: (508) 422-9788
Email: sales@soundimport.com

If you are unable to get tweeters from them, see if they will recommend a replacement or at the very least, provide you with the specifications, including the impedance, crossover point,frequency response, and power handling capability. If they won't or can't provide the information, then you are on you own. You'll want a relatively high-quality product, most likely 8ohm (but could be 16), crossover between 5-8KHz, frequency response from crossover to infinity (or at least beyond the range of human hearing).

Then try www.partsexpress.com. They have a large selections of speaker building products and carry small tweeters like yours in several brands, price ranges, and quality levels. Vifa is excellent. Tang Band is good. Goldwood is acceptable for entry-level speakers.

Hope this helps.

Modus One Six spare parts


You may want to check ebay, they sometimes have drivers for sale. Additionally, I would contact IAG (International Audio Group). They are the distributor for Wharfedale here in the states and may be able to help you. I also have the modus one-sixes, modus-two's, and modus center and was albe to get replacement parts from IAG, never needed a driver though. How did you blow it anyhow, these speakers can take a beating, are you using a quality amp? Underpowering the speakers and trying to drive them loudly = demise for your speakers.

Tweeters only works when touched!


This is not a solution, but I have the same problem. Obviously, the problem is with the tweeter not the crossover. I can't find a replacement tweeter so i am about to take it to my local stereo repair store and see if they can fix it. If you find a replacement tweeter, let me know.
