TBH tho the Chang is just box.
We can all build boxes, was this a design project where you get scored for innovation plus bonus points for "Out of the Ordinary"??

Tall wedges, pyramids, off-set stacked cubes, pipes and multiple pipes wire suspended spheres, oblate spheroids and tetrahedrons are all "Different" to the standard "Monkey coffin" box.

I wish I could advise further but my box-making skills are severely limited.

Daves pages on TLs have some ery interesting designs from a "Looks" perspective.

Transmission Line Speakers

Hi,

Whilst I agree the Chang isn't much more than a standard box it doesn't
look like a standard box, and that is the point. The level of innovation,
engineering and design accuracy required for the assignment is hard
to quantify but I imagine great technical skills are not the point.

As long as the OP is not doing anything that can be regarded as drastically
wrong, and IMO that is the point of coming here and asking, he should
be left to his own devices. He did find the speakers kit and the box design
on his own, consequently I'm happy to comment on some of the details.

Aesthetics probably comes into it a lot, pleasing proportions, domestically
appealing size, overall visual balance (e.g. a black stand will balance the
drivers, whatever the cabinet finish), and probably the write up counts
for a lot too.

The box is different to a "monkey coffin" and not a difficult build.

Other options of course exist, for the OP to explore if he wishes,
but so far IMO he is doing alright, and shouldn't overcomplicate.

While difficult, I'll try to be less lazy and less pointless: Did the original design
brief change while I wasn't looking? Where's the "funky"? Where's the "art"?


Hi,

You know the design brief ? What has "funky" and "art" got
to do with proper innovative speaker design any way ?

I don't know what the design brief is, but I'm pretty sure it
doesn't mention loudspeakers directly. Your being critical
without knowing anything about the academic process.

Whatever the original design brief is, every point in it
should be addressed by the write up, and covering
all of those will be more important than someone
saying "I don't like what I think you are doing".

I didn't get the Mission speakers, I'm just going to stick with the Kit.
I unfortunately missed out on that Pioneer amp, got back from work with the intention of buying it, and it had been sold, my own fault. Theres a Pioneer SA-510 on there currently, I shall try and snap that up tomorrow evening.
The design I've chosen is not 100% yet as I'm not at college right now, so could change completly, but it is at the top of my list currently. This is for my Final Major Project at collge. We did not get a design brief as such, we are to write our own, and we can be as creative as we like. I do not want to go into an art/design career anymore, as I've realised I want to do Agricultural Engineering after all, and because of this, my tutor allows me a little more leeway in terms of what work I produce.

Thanks.

MrNick posted a picture he drew of a monkey coffin, and I commented on it specifically and also quoted his request from his OP. Peace out, man!

Hi,

No he did not, its not your bog standard box, your being lazy.

As it turns out, as usual, a hi-fi project is not a good project for some
courses, in that the issues that matter are completely irrelevant to the
courses scope, and thus the same issues are pointless to elaborate.

Technology and Design would be a very different matter, for relevance.

Me peace out ? Not much peaceful about your unconstructive criticisms.

Given Mr Nicks comments, then I agree with you Sreten.
I build monkey coffins because I don't have the skills ( or the motivation TBH ) to build anything else, but there are others here whose work outside of the box is pure Art that also sounds exceptionally good.
my initial comments to the OP were directed towards that option.
Mr Nick, with simple boxes finish counts, but sounding good also counts so best of luck with the project, just listen to the advice already given and you can't go too far wrong.
 
I took a trip to Maplins today to pick up some speaker cable, there were quite a few different types so I wan't sure which to get, can anyone enlighten me on what is best/required for my project?

Thanks guys.
I bought a £16.99 20m drum of what they call Heavy Duty Speaker Cable. 42X 0.2mm copper, N20AP code:
Loudspeaker Cable 20m Drums : Speaker Cable : Maplin Electronics

An externally hosted image should be here but it was not working when we last tested it.


Good but not fancy.
 
Hi, Usually quite a bit of solder, tin all the exposed copper, rgds, sreten.

It prevents whisker shorts and prevents almost completely corrosion issues.
When you strip the ends and twist them for soldering try not to get finger
grease on them, use a tissue, solder them immediately, and discard say
the first 1cm of any cable that is not freshly cut, the end has oxidised.

You'll also find tinning wires and tags greatly eases quality drive unit soldering.
 
Can I just use any old solder flux then?

What do you mean by "tags"?

Thanks

Tags are the terminals on drivers and input cups or the terminals on "tag strips" people often use building crossovers. It's basically any small piece of metal that's designed to have a wire soldered to it.

As for flux, electronics solder will almost certainly be rosin core, meaning you shouldn't have to add any additional flux at all.
 
I cant beat £40, but i just got 2 mission cp-134 for 17Eu each, and cp-168 for 19 Euro each, and 4 of the Visaton FRS5X for ~9 Euro each. Two sets of cheapish 2 ways for £107, so ~$54 minus crossover though

Also can vouch for that speaker cable, ive got a small amount here, and about 10ft of the old 79 strand version Maplin did years ago lol
