Indeed. Or a painting or pattern that includes the speaker in a way that makes it appear as a part of the design or painting. A very light coat of spray paint, carefully applied, could help integrate it quite well.

IMO, unless sitting on a desktop or something, this driver is best used with woofer support, like a mid/tweeter. So box design isn't all that critical. 4L sealed and you're done that part. Cross over around 350hz to a 8 or 10" woofer in a ported box. Amazing sound for very little money. And quite easy too.

@cogitech - you are another smarty pants aren't you?
$249.00 seems like a good price IMHO
$45.00 Drivers + $10.00 Shipping - unless you have wholesale account and buy
hundreds of drivers at time.
$120.00 100% Wool Felt - per linear yard
$240.00 sheet of Carbonized Bamboo 1/2" Ply
$80.00 sheet of Carbonized Bamboo Veneer
$10.00Wire/Banana Plugs/Passive components(perhaps)/acoustic damping material
This alone is $505.00 - of course this is less if you make more pairs...
but if you are starting from scratch and want to make an identical or similar pair...?
And how much is you labor worth? - even if you are making minimum wage @ $8.00 an hour you not looking at any profit aren't you? ....
Not to mention website costs/shows/promotion etc...

In general you guys slam manufacturers but you often forget how much time it takes to put together a pair of decent speakers or any component matter of fact (unless you stuff raw/unmatched drivers into a empty coffee container) How much is your time worth?
What do you do for living? I thing you would be appalled if someone tells you that you are charging too much for your services.
Live and let live... and enjoy this great forum and music!

@tuxedocivic - there you go! I suggest 2L sealed enclosure as 4L will give you too much cone movement and distortion + if you are crossing @ 350 Hz it does not really matter too much how big the enclosure is. I suggest cross it at 100Hz for desktop and at 150Hz for other use - living room etc.

@yupvegas - The Tang Band W3-881SI is el cheapo alternative - the Tang Band W3-881SJ (similar one used in Yorkies I suspect) is much better with better high end extension, better midrange transparency and good looking cast frame - yes it is more money but as usual you get what you pay for...my five cents...

I don't agree with your analysis - dude, this is a DIY forum, our time is our passion and we freely put that in to build stuff that sounds better for less. With a little creativity and an open mind to using pre-existing stuff to make audio, you can save a lot of time and money. If we didn't want to put our freely available time we would be lije other consumers and just pay people to make it for us. $250 is a fair price if someone else made it for you, I agree. But this is DIY and you can't tell people to charge for their own time for their own project.

For example, the carbonized bamboo enclosure is a done deal at $18 ea on Amazon, add $10 W3-881si, $3 for usable binding posts (I would just run wires and skip the posts for such a small speaker). Free pillow stuffing, find some felt at Joann fabric or I prefer to leave the bamboo bare as it looks good that way. The stands can be cut from $17 cutting boards.

Make the stands from cutting boards.

Amazon.com: Core Bamboo 10488AM Amazon Exclusive Bamboo Cutting Board Set, 3-Piece: Kitchen & Dining

I am at about $80/pair and they will look pretty good as the finish is already done for us since we started with kitchen ware. I bet they sound just as good. Given that retail is 3x markup to account for labor and profit, 3 x $80 is $240 - a fair price. But DIY saves that $160.

@xrk971 - thanks for your input - your research put a smile on my face...these are good suggestions for DIY buddies...

I understand that this is a DIY board and its members have the right to express their
opinion and help each other to a better build but it does not mean that members have to use expletives towards manufacturers.
Especially if they are providing great product for a fair price.

Just to clarify few things:
The W3-881si is not in the same league as the Tang Band W3-881SJ - yes for the $9.90 it is great buy (buy while you can as there is only few pairs left) and it is lot of fun and I can recommend this driver 100% - but it is not the same as his bigger brother..
So add another $28.00 to your calculation if you want to get the similar sound.
Now you are over $108.00 for a pair with the containers from Amazon...
Is it comparable? Hard to say unless you can compare directly - anything else is a speculation or perhaps an educated guess but guess nevertheless.
So assume that it does sound similar and your price is $130.00 for a final build (had to add for shipping, wire, screws etc...) this is not accounting for any of your labor as you mention this is a hobby and labor of love - agree there and you save $120.00 futzing all weekend doing so - that is OK with me if you have the time and money...

To finalize my blurb - $249.00 is a fair price as we both agree and that was my point.
Also to consider - if the manufacturer sells at wholesale keystone pricing they are below the $130.00 (of your final build) so the margins are super thin and not the 3x markup. Nothing is as simple as it seems at first...


Btw like your thread on the foam core builds - I have been using foam core for my protos for 20+ years now... great starting point and in some instances could be used as a final inexpensive build - good job there Dude..

One more thing - all above is assuming that you have all the tools to drill, cut, solder glue, finish, shrink wrap etc...
If you are starting from scratch - easily add the $120.00...and then some...

The joy of building and learning is hard to factor into a cost analysis. It's either means everything or just doesn't factor at all.

I've ordered a few of these to try at my desk at work. I'll post some results when I get them. I've heard Ryan's execution with woofer support and it was excellent.

@KyleinCowichan - that is called R&D... yes agree with that.
you should be pleased with these - I have them slightly EQ on the top and the bottom - sounds pretty good indeed.
