See picture for an easier explanation. They guy selling these claims it hasn't affected the sound. Is it likely to have?

johnr: not to the human ear


Ok cheers. Is it literally just a cover and not involved directly in the sound reproduction process?

Anyone know if it's easy/cheap to repair?

It's primarily a dust cap to keep dust (strangely enough!) out of the voice coil.

As johnr noted, it will have almost no impact on the sound, but if you are an audiophile and sit down to concentrate on listening to music, then you may notice a slight difference between the left and right speakers.

The impact will be at the higher end of the frequency response for that particular driver, but given a 2 or 3 way system, this will likely be above the crossover frequency at which the next (i.e. midrange or tweeter) kicks in, so unless you are really critical, you probably won't notice.

BUT - if it's been like that for a while, and dust/dirt has got in where it shouldn't, then it can damage the voice coil pretty quickly - this will come across as a scratchy noise as the cone moves, with lots of sound distortion.

Probably not.
But it would pay to find out what happened to it as other parts may have been damaged in the process.

Repair is not expensive.

It will also be venting into the driver, so could change its response substantially acting as another port depending on the internal construction of the driver.

They are an easily available part and just glue on, but they shouldnt come off on their own so it may point to the speaker being "repaired" - I had a pair that was fixed and the dustcap on one was on crooked

It depends on the design of the speaker a little bit, if that section is supposed to be semi-sealed then the missing cap will reduce the cushioning of the cone. Unless you intended playing them at very high volumes, it'd be unlikely to be an issue even if this was the case though.

They're usually damaged by small children playing with them, which is a prime reason for leaving the covers on them if such creatures are about.

Any reasonable audio shop could sort out getting them repaired, but they'd probably charge a disproportionate amount. If you're in Wellington then WT Audio in Lower Hutt would be the guys to contact for a reasonably priced job.

those look like infinity speakers.

you can buy the dust caps and the rubber cone surrounds from the US for about $50. just glue them on yourself. there are loads of how to's on the net.
i have a set of 8" infinity refernce drivers that i will re condition when i get around to it  using those parts

Yeah they were infinitys. Guy was selling them for $500. I didn't get them in the end though.

Got some pretty nice JBLs instead. Guy set a low $200 reserve but set his auction to finish at a crappy time (10:35am Tuesday). No one had bid with 2 mins to go so I thought wth and got them at reserve. The guy said he had over 50 watchers and was expecting them to go for around 500. Doh!

Setting a reserve will do that to your listing. I usually dont even bother adding reserved listings to my watchlist.
