Hi,

Kinda playing with the idea of building my own cabinets and setting it up.

Aside from big bits of wood ;) , what else would I need?

I had a look on the bay, and there are components for different manufacturers like Mission and Wharfedale.

I figured;
Some sort of tweeter
A mid-range Woofer.
And a slightly larger woofer for underneath.


Now, I am running it off a Denon PMA-320.
It only has 60W per channel. It has four channels, but I would prefer to run it off two.

A or B Speakers - 6-16 ohms.
A and B Speakers - 12-16 ohms.

I heard I need a crossover? What is it for?

Am I swimming in dangerous waters or on a winner?
I'm slightly on a budget, this is why I decided on building my own.

Thanks

Any help is appreciated :)
 
Ok, don't want to sound patronising, but you haven't a cat in hells chance !!!
So this is what you need to do,
Read this book several times:-

The Loudspeaker Design Cookbook by Vance Dickason, (latest 7th edition is a stonking £35 :eek: ) Then the scale of the task will be clear.

Scour net for design software, you'll need this to put in practise what you learnt from the book.

Work out what drive units you want to develop with... acquire the Thiele Small parameters, feed them into the software, and start working the design up.

Build and use measurement equipment you have bought, test and tune.


OR
Choose a design from a design/kit on http://www.wilmslow-audio.co.uk/ and follow the instructions...... :)
 
Lol, okies :)

Ill read up a bit more then before I make a decision.

Anyways, I have uno question.

If we have two speakers, speaker A and speaker B.

Each have a RMS of 100W

After being connected to the crossover, what is the actual load on the Amp?

Are they simply added together to make 200w? Or is the load split between them due to different frequencies being split? Making the load 100w?

Thanks
 
LOL Read the book ;)

RMS is a measure of how much average power they will take.... nothing to do with load on an amp,,,,, don't worry about the "paper" numbers.

So you have an amp, and you want 1 pair of speakers yes ???
 
Yup,

Do you know what, I am absolutely confusing myself. I reckon I will just buy a couple of floorstanders and be done with it :D

Anyone got any reccomondations? Sub 150 ideally.
Was looking at the Kef Cresta 30's and the Wharfedale Zaldek 1000

Thanks
 
I have some Kef Cresta 1's (older model of 10 I guess) for rear channel, which is small bookshelf speaker, they sound pretty good for the money. So the floorstanding version should perhaps be a bit better, as long as your room is not to big.
