B&W Tweeter replacement "?" - Blu-ray Forum

Beta Man · 03-14-2008, 01:03 PM

So, here's the deal, One of my rear speakers, a B&W 705, gained the attention of our Nanny's 3 year old daughter (who she brings with her everyday to our home)

The toddler removed the grill thing, and the shiny dome tweeter was just too sexy to resist I guess, and she caved it in with her finger...... it was only a small dent, and I looked up some info on the internet and figured out how to pop it out (special tape that didn't leave the adhesive on the dome) Now the tweeter dome has a small bit of discoloration from where it was "stressed" (I could take some pics but I don't even think it'd show up in pictures)

There is no noticeable change in the sound, and I even used an SPL meter on a table in the middle of the room, and did high-tone tests with Left, Then Right surrounds, (ran them as mains to put more power to them for testing) and there was no difference.

Despite all of this, and the fact you can't even tell unless I told you what to look for, I got a new tweeter assembly for it, because I can use the other as a spare if something worse ever happens to my L/R/C or rears (all 700 series with the same tweeter assembly)

Does anyone know what "tool" I need to remove the tweeter assembly on these speakers????? It kinda looks like a very small "Torx" but it's not, and it's not an allen (sp?) wrench type deal. Some sort of "STAR" I guess......

I'm told it's just a plug-in deal once I get it off though.....

The shop didn't know b/c a B&W rep goes to their shop to replace all of theirs (a lot of kids running around unsupervised in an audio shop is a BAD thing I guess!)

They ordered me an extra because they had 8

of theirs replaced.....

ALSO, if anyone has any good ideas to keep the grills on (if you're aware of these speakers, you know the tweeter grill isn't cloth like the other grills, and it's plastic) short of tape, or glue, or anything else like that! I really don't want to replace these tweeters very often, because they're pricey.

ouch that would would have maid me blow up, anyway they sell star bits and screw drivers at all of the home improvement stores. like these they come in all sizes http://www.amazon.com/6-pc-Star-Drive-Bit-Set/dp/B000NPR2LM/ref=sr_1_6?ie=UTF8&s=hi&qid=1205500915&sr=1-6
although a star bit is realy a torx bit so that may not help

Beta Man · 03-14-2008, 01:35 PM

see.... I looked really close, and it doesn't look like anything I've seen before..... I'm worried that it is some special tool..... possibly someone from the UK would know about this.

Yeah... I was pretty upset, even after I got it "fixed" and found the sound was not affected...... but the OCD in me made me order a new one, and when they said $140 for the tweeter, I could only laugh at the poor girl on the other end of the phone!!!!!

wem003 · 03-14-2008, 02:23 PM

Can you post a picture of the screw head?

We have a great audio shop here in Raleigh - Audio Advice, and they would probably be able to tell you how to get the tool if its special.

Well..... I'm going to get the replacement tweeter after work today (it's been sitting at the shop for 3 weeks..... It's 30 minutes away, and I've been BUSY!!!)

When I get it, and get home, I'll try to take some close ups, but they are black screw type things, and the tweeter is black, so it might be hard to get a good pic of it..... but I'll try!!!!

T-Town Oil · 03-14-2008, 04:21 PM

yeah man, post a pic. ive got a book that should have the name to every type of screw/bolt head ever made.

thanks! I'll put it up tonight.....

T-Town Oil · 03-14-2008, 04:25 PM

here are some specific names you might try googling to see if its close to what you have. fluted socket (4 or 6 flutes), MorTorq, Tri-Wing, 5 or 7 Node Security. those are a few that resemble a torx in my mind. hope it helps

ManUtd · 03-14-2008, 04:30 PM

I would call B&W America and ask about that tool, just to be sure. BTW, I just learned that these replacements tweeters aren't that expensive as I originally thought, a friend got the NT tweeters for a little over $100 I think.

DiverSpear · 03-14-2008, 05:25 PM

If they are what's called tamper proof torx or security torx you can get the tool at electrical supply houses, i.e. CES (City Electric Supply)

Beta Man · 03-14-2008, 10:59 PM

Turns out it was one odd screw... they were phillips heads..... I'm an idiot I know!!! here's the pics... before, during, and after.... bad pics, so you can't even tell what was wrong with it!

I'm sitting here waiting for shutterfly to send me the email so I can copy the link!!!! I'm new to all of this......

http://share.shutterfly.com/action/w...r&linkid=link2

Trust me... .there was no way I could take a picture of the screw heads even if I wanted to...... they're recessed in the plastic casing.....

kingofgrills · 03-14-2008, 11:18 PM

Sorry to hear you had to go through all of that. Have you had any luck finding a new nanny yet?

guitarist155 · 03-14-2008, 11:19 PM

at least you didn't need a special $400 screw driver

btf1980 · 03-15-2008, 01:01 AM

<sigh> Looks like i'm in the same boat as the OP. My 6 yr old nephew pushed in the tweeter on my CM7.

The kid doesn't move for like 2 hours, but the minute I get up to take a leak, he runs buckwild and pushes my tweeter and acts like nothing happened.

Kids and expensive speakers don't mix.

Gremal · 03-15-2008, 04:22 AM

Call the dealer who sold it to you. If it's still under warranty, they may be able to help you for free or for the cost of a new tweeter and they'll send someone out to do the work.

Beta Man · 03-15-2008, 05:38 PM

ha.... nope... no new nanny.... she's a bargain.... even with the cost of tweeter replacements.

For the guy in the same situation, if nothing else, rest-assured it was easy to replace!

I'm going to try to find that white tacky stuff they sell to hang posters on the wall etc. to secure the tweeter grills..... it shouldn't leave a residue....

Beta Man · 03-19-2008, 12:45 AM

Came home from work today and BOTH tweeters (even the 3 day old one) were pushed in........ I'll vent more tomorrow.... I'm going out to have a pint of guinness

guitarist155 · 03-19-2008, 01:08 AM

dude with that luck just keep a keg and a tap around, same thing happen? i would say sadly it may be time to have a talk with that nanny about letting her go if this won't stop and have her pay for it

gearyt · 03-19-2008, 01:11 AM

how about a diamond plate speaker grill ??

ManUtd · 03-19-2008, 01:48 AM

Oh that's not good at all, time for a serious talk with the nanny.
