Sell them and build or buy better speakers.

If you're not just trolling ...

It's best to explain why you'd want to do something like this.

For one thing, B&W are some of the better engineered 'mass market' speakers out there. It's doubtful 'adding a tweeter' is going to do anything beneficial.

Why do you want to add an external tweeter? What's your goal? Whats wrong withe the existing one?

You're the one who wants to add another tweeter to your existing speakers. Must not be working so well.

For starters, folks will need to know which B&W since there are many. Second, unlikely to succeed unless you have the crossover layout and values. You'll still need to get into the box to make crossover changes. At that point, I'd be thinking about a tweeter replacement instead, which would rapidly lead to new speakers altogether.

Plus you haven't mentioned why you think you need an additional tweeter.

Finally, you asked what people thought. Thoughts and opinions are the same? No?

Maybe my ears are a little affected at my age, but I would like them to be a bit more airy? I thought by adding an ext tweet and position them upward might help

They are CM4s

my opinion: I don't think it is worth it to add a tweeter to your speaker. If you don't think it is not airy enough for you because of possible hearing loss then maybe you should just EQ the upper frequencies to suit your taste...you can use a pc program for that or buy an external equalizer. If not then I think Face's recommendation to build or buy another speaker of your liking is a better choice.

Does that mean you are not now listening on-axis with the tweeter?

The CM4 is a pretty nice speaker, and already a touch on the bright side as well.

Do you have a "dark" room, with heavy carpet, drapes, upholstery, etc.?

Trying to add a tweeter would create more problems than it would solve, and kill any resale at the same time. It used to be that B&W dealers would accept trade ins.

I just auditioned the B&W XTR-4, a slim floor stander that sounded very nice, but a little to hot on top for my taste.

So, yeah, probably best to find a speaker you like, buy or replicate it, and put the CM's on Audiogon or ebay, or trade them in. $.02.

Yeah, that seems odd. Most B&Ws are a touch "hot", though I sort of like it. Good basis of comparison for linear vs. non-linear distortion - that is to say, the distortion sounds entirely linear.

What you want is a "Super Tweeter." One you can set on top of your existing loudspeakers without changing anything. Some of the super tweeters already come with a stand/holder that will allow you to place it anywhere, otherwise you will have to design/build your own. GOOGLE up "Super Tweeter" if you'd like to see more pictures and learn more.
Take a look at the pictures below.

I wondering if it was a case of diminished hearing in the top octave,
And if ( to what extent ) it could be helped with careful placement and appropriate room treatment.
What many relate to "airy" is around the middle of the top octave. ( Mackie calls airy around 16KHz ).
If careful EQ ( not a tone control - but 1/3 octave ) cannot restore it: and it's a matter of augmentation:
I'd also consider a ND20FB module or a TN28:
Set the crossover for the top octave

first off it is your home and your speakers.

I would say a pair of these

buy this from me

buy this crossover

use adapter cables to feed it and the two amps




mount tweeters on an oak or maple frame. and you should be good to go.

cost is around 400 you get full control of added tweeters

Why not run some test tones through your system , I did this and was surprised how poor my hearing is in the higher frequencies, after about 16kHz I couldnt hear much, but my old dog was giving me some funny looks.
This may give you an idea about what you need to achieve.

Why not post a picture of your crossover here? A slightly different tweeter could boost your highs, or even just swapping out a series resistor (or eliminating it). Generally, a new pair of resistors could be had for about $1 a piece. Lot's cheaper than tacking on another tweeter.

You could try buying a pair of piezo tweeters real cheep and wire them in parallel and see what that does . They don't need a crossover and can be padded down easily .You could even point them toward a wall to give it a more indirect or open sound. If it doesn't work you haven't wasted a lot of $$.
