Nexo PS8 Diaphragm

[tinnitus_man]

Hi everyone

 

I was wondering if any of you know of a replacement for Nexo PS 8 diaphragm? On the Diaphragm it has HPA12ND

 

I have had a quote from Fuzion but it's silly money. I know that most branded speakers out there have other make branded speakers / diaphragms in so what would this be? I notice that B + C has been mentioned for the PS10.

 

Many Thanks

 

Stuart

SSE Audio Group do them - here

Thanks for the reply...

 

I've tried SSE for the parts but again rather pricey.

 

Will a B & C DE12 fit it? has anyone used this in a PS8?

 

Cheers

The key issue with many of the up market speaker brands (and even the not so upmarket ones) is that the speakers used are not "off the shelf" versions. Sometimes a standard model is customised to provide a particular performance that the speaker designer needs. In other cases it's a question of tolerance, and there are times when only a few drivers out of a large batch exhibit the required tolerances to work to performance needed. This is all the more important in loudspeakers where the protection system relies on the driver behaving in a known and predictable manner. Apart from the overheads incurred through stocking and maintaining spares, these drivers are of necessity higher cost because they are specials or selected items.

 

Of course, you can buy something that is close, but it may not be identical. In some cases this is instantly noticeable, in others it is more subtle. It's not likely that it will be the same though. The question will be, do you want to potentially compromise the performance of your expensive loudspeaker with something which is 'nearly right' to some degree or another? If so, keep looking for an "alternative". If the answer is no, then you need to stick with the proper spares.

 

I thought that there was some measure of protection built into the Nexo controller? How did the diaphragm blow?

TBH £47 is pretty good for a Nexo product as from memory the JBL EON replacement diaphragms are at least double this. As Simon says the NEXO PS8 give the quality it does for a reason.

[abbotsmike]

When a full box is what, £800? I'd say you cant grumble at <£50 for a diaphragm. They are lovely sounding boxes and I wouldn't want to run the chance of compromising that personally.

(He says, in the process of paying a similar amount to have a PD 12" sub driver reconed, after learning just how much they dislike not having a good HPF on them in certain enclosures!)

You you consider fitting a after market unit into the PS8's ? If so let me as I have a chap I've used before for a load of JBL units that came out of a club.... cant tell the difference and the price is about 50% off retail

Hi folks

 

Thanks for all the replies.

 

I used to work at a hire company the director there knew everything that needed to be known about re coning expensive speakers. I have seen it all in my time there. I remember the L Acoustics sub speakers that were re coned there with Beyma re cone kits, and before anyone says that you are compromising quality they were exactly the same down to the last detail - there was even a number printed on the cone that matched the L Acoustics cone that came out of it! identical in every detail.

 

I did search the net on the Nexo PS8 diaphragm and even called a few big speaker re conning companies and they immediately said B&C DE12.

 

I'm wondering how the Nexo diaphragm went O/C as well, apparently setup all correctly so I'm told!

 

BTW I did found a company that did sell the NEXO diaphragm at a good price in the end so I will be buying it from them. All the other companies were over £50 + VAT. and then delivery on top. One company quoted me over £100 including delivery ex VAT!!!!!

 

Just shows shopping around is the best way to get the correct price.

 

Thanks everyone for your replies.

Give Proel a call. We had to change our PS8 and PS15's, replaced them with B&C from Proel and have had no problems, they sound great.

Hi guys.

 

Same old story isn't it? Everyone is trying to get the same performance on the cheap.

 

The driver in the PS8 is "based" around the DE12. This is true. However, it's NOT a DE12. The diaphragms are VERY different and are built to a differrent specification. Sure, you could get the DE12 diaphragm in there but it simply won't last very long and it won't sound the same. It will certainly break up at high levels and doesn't have good thermal performance.

 

Nexo use and specify special "aircraft grade" dopes and glues on their components. They also specify the materials that the components are made from. This makes them more expensive but it does ensure that they last *much* longer and can withstand stress much more easily. The controllers are programmed and mapped to this specification and can deal with issues such as over excursion and thermal damage. If you put the wrong diaphragm in there the controller simply doesn't work as the end component does not behave as the controller thinks it should.

 

Yes, we sell Nexo - have done for years but as we also see the failures too we know what works and what doesn't. I personally have seen standard DE12 diaphragms in drivers that have been returned for "warranty" replacement (yes, people do try it on all the time). If you want to do a replacement on the cheap do it by all means but you won't get the same dynamic or thermal performance and the replacement WILL burn out and you'll have to replace it again (which will actually double the cost of your "cheap"replacement). The same is true if you try and use an XTA Processor or a SoundWeb to "mimic" the curve.

 

As I've already said in a previous post on this forum, there is NO eq curve as all of the processing is dynamic - it simply does not stay still. You can't reproduce the controller's behaviour with a standard static eq curve with a limiter on it.

 

Whilst other companies do indeed use standard specification components in their drivers Nexo don't and have never done this. They have genuine reasons to do this as true Nexo users will testify.

Thanks for this information.... I might not have been wrong after all? ;-)

It is NOT a normal DE12 diaphragm indeed (that is a 25W RMS diaphragm with a mylar membrane , witch is white coloured )

But , it is a regular DE 12TC - 16 Ohm instead (that is a 30W RMS diaphragm with a titanium membrane , witch is silver coloured )

All thoe the speaker has an 8 ohm impedance , the original diaphragm is a 16 Ohm one , I can assure you THERE IS NO DIFFERENCE ,

of sound or materials used , the only differences that NEXO made are ( the plastic screws , and over the metal part of the diaphragm ,

is a thin white round foile of plastic (that does't allow the metallic part of the diaphragm to touch the metallic part of the driver body itself ,

witch you can easily take it from the blown one , and that's about it !!

[Simon Lewis]

Apart from the time warp moment, I cannot comment further.... You are convinced it's a regular diaphragm, and the guys who sell Nexo say it isn't...

[fl0rin3lul]

the woofer is a regular B&C 8NDL51 , I've dissasembled to pieces a nexo one and a regular one , they are THE SAME , the only thing that nexo does is put the speakers under a more severe Quality Control process ( it even writes on many brochures , that the components are selected carefully ) but that's about it !! The body of the driver however is indeed custom made , because I've seen it only in PS8 , and GEO S805 , the only speakers they had made custom , in some subs (I think the CD12's)

the B&C 12HPL76 a 6 ohm version !!

Do you work, or have you worked for Nexo in the past and are able to verify these statements you make?

 

It seems a little odd that you would bump a 3 year old topic, especially when your profile says that you are 'working outside the industry' that's all.
