Hey guys, new here.
For my college project I want to build and design a set of small speakers. I want these to be of reasonable quality as I am going to use these myself afterwards.
My first thoughts was a two way system, however I have no idea how to wire crossovers or what drivers/tweeters to use together.
Someone has mentioned to me that a full range speakers are much more simple to wire but cabinets are more complex, so would a pair of these be more suitable?
My college course is General Art and Design, so if anyone can give me inspiration on funky, yet good enclosure designs, that would be fantastic.
Sorry if this is posted in the wrong place.
Many thanks.

The Parts Express TechTalk forum is about 99% DIY speaker oriented. If you look around the site, you'll probably find something you like. And I'm sure you can get as much help as you need. A lot of people like the funky side of speaker building too.

For £40 you are not going to get the best drivers in the world. It is a very simple first order electrical crossover, which means the frequency response is probably going to be poorly controlled.
However the statement in the add is probably true it will sound allot better than a pair of speakers you could buy for £40.
You are not going to get massive volumes from speakers of this type. If you want to achieve student party levels the easiest way is to buy larger drive units as they are usually more efficient. However if you have a smallish room the will probably be enough.
At least it simplifies your problem to building a funky cabinet for them.
If you told us more of what you want to get out of the speakers then we could tell you more about what drivers and solution you need. For instance how power full is your amplifier. If it is a tube amplifier then you will need a very sensitive speaker. If it is a 1000W PA amplifier then something based on PA drivers would have more chance of surviving.
Do you want to use it for parties.
What sort of music do you like and how loud do you normally listen.

Andy

I have come across this speaker kit, can somebody please pass their
eyes over it and tell me whether it is any good. any thanks, Nick
Hi,
Its cheap and cheerful and very good value for £40 delivered.
The bass driver specs :
Resonance: 50Hz
Sensitivity: 89db 1w@1M
Impedance: 6 ohms
Power: 60 watts nominal
Frequency range: 46-6000 hz
Qms: 1.48
Qes: 0.57
Qts: 0.41
Vas: 29.5 litres
Chassis: 180mm square
Baffle cutout hole: 140mm
Its designed to work in a ~ 10L sealed box, ~ 15L vented box.
The simple x/o almost certainly has no built in BSC and the driver Qts
is low enough that it would work well in decent sized BIB's and BVR's
designed for FR drivers to boost the low adding some BSC.
The tweeter may need some padding to bring it level with the bass/mid,
it really is a cheap x/o, but the drivers alone are easily worth £40.
FWIW the kit should work well in the FreddieChang BVR posted earlier.
Fill the triangulated section with sand for stability and damping. Add
some bracing. Top needs foam lining. Possibly invert the drivers, i.e.
bass/mid top, tweeter just below. possibly offset tweeter centre to
0.6 of baffle width and build mirrored pairs. Bass can be adjusted
by adding pillow stuffing behind the driver.
They will go lot louder than a FR, and for the price hard to better.
rgds, sreten.
maybe u should build something like the Cyburg needles or Frugal Horn MK3

I primarily listen to a lot of Electro house music etc. But used to listen to a lot of extreme metal (big diversity I know ), but so long as these speakers are of acceptable quality I will be happy as they are only for my college project, and will probably tackle something more expensive at a later date.
I dont currently have a amplifier, but I am look for a decent cheap second hand integrated amp, suggestions are more than welcome. I was thinking something like a Cambridge Audio A5? I heard NAD did a good one which can be picked up cheap these days.
So sreten, you are saying that If I buy the driver kit I mentioned, and fir them in the Freddie Chang, they should perform well so to speak?
Also, how do I pad the tweeter like you mentioned?
Thanks guys.

Hi,
When it come to "wacky" and "funky" cabinet designs its hard to
predict whats going on. The top volume of the Chang is about
right for the driver but the port opening I really can't work out.
I'd move the angled section to 1/2" away from the port rather
than 2" and consider experimenting with adding furthers section
to extend the ports height from 3/4" to say 1-3/4", 2-3/4" and
4-3/4" and see which works best.
If you don't want to mess about my best guess is reduce the
width from 1" to 3/8" and the angled section to 1/4" away.
To adjust the tweeter level down, add 1R, 2.2R or both in series.
There are a lot more technical ways of doing it, but
that is not that relevant for your course AFAICT,
you want an interesting looking cabinet, not a box.
rgds, sreten.
If you need a hand with the maths of the angled piece, ask.
Amplifier ? Used a Pioneer A-300X is very good.
On a serious budget ? worth £25 IMO :
http://www.ebay.co.uk/itm/Pioneer-S...i_Amplifiers&hash=item2ebd2d6791#ht_500wt_834
(Might need a simple attenuator to work well with CD players.)

Thanks a lot sreten, when you say add 1R, 2.2R or both in series, what do
you mean by this? Sorry I am new to all of this technical speaker stuff.
Hi,
Ceramic Wire Wound Resistors 5W - Resistors,Pots, Switches
Wire 1R in series with the tweeter for a some reduction, not enough ?
Wire the 2.2R in series instead. not enough ? add the 1R in series as
well, a bit more attenuation but less difference than the first two.
In fact go for 1.2R and 2R from that link I posted,
gives you the best range, 1.2R, 2.0R or 3.2 R.
rgds, sreten.
Hi,
amplifer link doesn't seem to work :
Pioneer Stereo Amplifier SA-520 | eBay
try again, rgds, sreten.
Works, good buy for the cash strapped, jump on it.

Ok thanks, I will bear that In mind, out of curiosity would I be able to pick up a pair of full range drivers
for £40 odd to fit the Freddie Chang or not? And if so, how exactly do you wire full range speakers?
Thanks
Hi,
You simply wire then to the input terminals and hope for the best.
Technical types tend to add filters to manipulate the response.
TBH for £40 delivered you aren't going to find anything better,
or find cheap FR's with enough specs to ascertain suitability.
Ordering the bass units, tweeters and x/o's separately is £70.
rgds, sreten.
I suspect how good they sound and technical details will be
fairly irrelevant as to how well you are marked, but if they
work well for the cost it can't hurt, as well as looking as
though they cost a lot more than they actually did.
