Mission 733

[admin_exported]

Hi there, I'm hoping someone can help me. I'm not a technophile, so apologies for not knowing the terminology on this.

I have a great pair of mission 733 speakers, about 15 years old. At least they were great until the delicate plasticy cover on the cones cracked and failed a few weeks ago. Just can't play music through them now.

I've tried a google - and the only place I can find which offers replacements is for the whole unit at about £65 each and I would need to make modifications to the surround as they are not a direct replacement. It seems mission have stopped making spares (though I have just fired an email off to them in the hope!!)

I am on the outer hebrides, which adds to the problem of getting someone else to repair.

Ebay is listing a 13 year old pair at £100 which a mate said he would collect if needs be, however the cones on these too may be just waiting to crumble.

Can anyone offer any suggestionson repair/replacement

or a new speaker replacement suggestion. The speakers are set up with Rotel RC-9708X/RB-970BX amp and Marantz CD-63SE cd player. I really like the sound of this set up.

thankyou in advance!

Are they 733i's? I still have a pair, which I have only replaced this year due to the same reason as yourself, so I have 1 good 1, and 1 with a cracked cone. They still sound great, I just thought I would replace while I was updating everything else. Unfortunately I'm nowhere near the Outer Hebrides, but I am just south of Scotland, left hand side as you look at the map, love to help you out if I could.

I have a pair of Mission 753 floorstanders, my dog once chewed the centers out of 3 of the 8 drivers. The shop where i bought them from said the replacements (whole Driver) only cost £15 each. it was a few years ago. I'm not an expert either but i think that its not so much the drivers themselves that make the speaker but the crossovers and tech bits inside. so if you can just buy a driver the same size id try that.

Hi lou, you could also try dropping Mission a line at their service email - rob@iaguk.co.uk, or phone 01480 447700. No idea if they can help or carry spare parts going back that far, however it's worth a shot. Failing that, you can often pick up 733 / 733i speakers on Ebay for a reasonable fee (very often in the £50-75 bracket).

I used to have a pair, they were excellent - this was the 733i model. Used them solidly for a decade and loved them. Upgraded a few things in time and they had to make way for the current 752s that I use. Otherwise, they did a great job with the music, an easy and enjoyable listen.

I had a similar issue with my 733i's where one of the cones split due to age i'm guessing, i spoke to mission and have bought a pair of new compatible cones which are all black rather than the clear plastic original cones. I was reliably told these should be a straight swap out, but won't be able to do this till the end of the month as the speakers are in storage atm.

Looking on-line it looks like the replacement cones are the ones they use in the M33's.

Many thanks for all the advice so far!

drrockwell, ah dogs! Though the cones were already split I think it was my dog who finally fractured the cone of one (rendering useless), the cone is suspiciously at Dalmatian tail height and I noticed him wag straight into it today - bless! (i should have the covers on though). I think it was the driver unit that Ifound on line for £65 a pop, so an expensive solution for the pair, especially if I have to modify the surround and wiring.

the record spot - thanks, I emailed mission earlier today - so fingers crossed (though hopefully cheaper than £130) Do the 752's have a similar sound to the 733's (there is a pair on ebay for sale at he mo')

D3CYPH3R - Hopefully I'll get a positive response from mission for a reasonable price. If not I guess my options are to shell out £130 and modify, or buy second hand replacements, or second hand replacement speakers.

Thanks for the replies so far, any more advice would be welcomed!

The pair i got were £57.34 delivered.

Lou, the 752s share a similar "house" sound but there's a good step up too. At first I couldn't work out which I preferred; the 733s really focus the music well, whereas the 752s let it open up - there's a greater sense of scale to the music. I'd had the 733i speakers for about ten years, so listening to something else took some getting used to. In the end, with the right amp (Sansui AU-217 initially) it started to click. Upgrading to the current amp made all the difference and they really sing now. Given you should be able to land a decent pair for about £100, maybe a little more, you'd need to spend a fair bit more to improve on them.

Many thanks for the help and advice. See what response I get from mission!

 

[the record spot]

I need to revise my estimates on the 752s; I had a look on the 'bay yesterday and they had a pair at £155 with a day or so left (I think) on the auction. Okay, £100-200 then!

 

[Anonymous]

Aye, I have my eye on a pair and their are cranking up in price!!

Someone should really put a parental control on my computer for ebay as I have spent all day surfing the retro items, some which have sold for big ££'s .........and I have been tempted..... a mid life crisis thing I'm sure!!

Thanks again to everyone for your help

 

[the record spot]

I'll shut up now I think. They went for over £300. I've got the original boxes as well, the grilles need a wash (kiddies hand) and there's some minor paint flaking off the bases, but otherwise, they're near perfect. Hmmm...

Well it is a case of mission impossible i think. This was the response I got:

Dear Louise

I'm afraid that the bass units for the 733 loudspeakers are no longer

available.

Regards

Nicki

I sent a fairly detailed email and thought they would at least try and offer some advice on replacement!

Guess I'd better get surfing the ebay!

Is this the standard response from major HI Fi manufacturers to product queries and requests for help?

Cheers to you all!

 

[Blackdawn]

I think this is quite resonable. I would look at Ebay or similar auction sites for new drivers/ or spare speakers.

 

[the record spot]

Sadly, I think the response from the company is what you might expect to some extent - Mission will probably carry spares for some speakers, but the 733s came out in the 1990s and they've turned out a fair number of products since then. In the same way, Linn provides support for the Sondek turntable going right back to the very first models from 1973, but they stopped providing support for the first generation Mimik CD player a few years ago and that appeared in the mid-90s I think.

As I said earlier, the 733 comes up frequently on the 'bay, you'd be well placed to land a pair for about £50 I'd imagine. Check out Gumtree as well for your area. Sorry they couldn't help.

Cheers the record spot. I'm pondering lots of options and keeping an eye on ebay. Meanwhile I'm missing my lounge system!!!

Hi, I just thought I'd post the conclusion to this just in case anyone came across the thread via googling a similar problem.

After prompting mission in respect of suitable replacements and quoting D3CYPH3R thoughts that the replacements were possibly M33's, mission finally verified that these would make a suitable replacement. (Many thanks D3CYPH3R) The cost is £20 plus vat plus postage for each driver.

Another note, it took quite a number of calls before I got an answer from the mission contact number, so keep trying if you don't get through initially.

So all's well that ends well and hope I don't have too many problems fitting the new units, and that the sound is still akin to the original.

Thanks again for every one's reply.

Hi. I've been reading your thread with interest as I am now having the same problem as you did. One of the main drivers has torn. I think something got pushed against it whilst we were decorating.

I am about to phone up Mission and ask for a pair of drivers for M33s. Before I do so can I ask did they drop straight in without any work to the cabinets?

Thanks

Jonah

Hi,

I have replaced a few of these drivers now.

The original drivers are no longer manufactured so to replace them with originals you will have to obtain them second hand. As these drivers are very fragile they are quite sought after and fetch up to £60, or so, on ebay for the driver on its own. However, the driver is identical to those found in the 732.

A pair of 732s can often be purchased on ebay for around £30 plus postage. You might even find a pair with a single cracked driver for less than that (if you only need one). It's a very easy job to replace the driver and you might even sell the drivers you didn't need, seperately, on ebay for more than you paid for the complete pair of speakers!

Don't buy 73s or 731s as these use a different driver.

Trust me, this is by far the most economical solution.

Thanks thecharmingguy. In the end I got impatient with waiting and phoned up IAG and brought a pair of M33 cones to replace my originals. They fitted in surprisingly easily and sounds ok. Doesn't seem right though when I look at them and they are all black now.

Oh well, turned up very quickly so I can't really complain....

I should probably put the old cone on e-bay for someone else to use.

 

[philpot1001]

looking at the dates on this im a "little late" to join in lol, but here goes.

I just noticed my Mission 733i left speaker has hairline cracking in several places on it thats now rupturing to the surface, so im almost in the same boat. I looked on ebay and there are spare drivers on there, varying between £5 - £20 with "buy now" depending on the health they are in (some seem disorted).

My plan of attack is to try and repair my cones first, if that fails buy a 2nd hand driver from ebay. My proposed repair process will be as follows:

use superglue and try to get the glue INTO the crack - the object here is to use the glue to effectively weld the crack together. While the glue is still setting, use a cloth that has a small amount of solvent on it (white spirits) and rub over the surface to remove surface glue.....you dont want the cloth to be wet with solvent, just damp

As superglue basically melts plastic it should effectively weld the crack together when set, and as long as no glue remains on the surface should not effect the sound quality. Going to try it tonight as ive got nothing to lose, and if it works will post a separate post on fixing cracked 733i cones. Fingers crossed.

Lol.....

A silicon selant...May be better. It does not dry brittle like super glue, has a better/thicker consistency. And will not 'melt' your cones.

Please come back let us know how you get on.

You could enquire about having them reconed, there are a few companies that offer this service.*smile*
