please help to design 3 way system.

[vishnupg]

Hi,
i am totally new to design a 3way system,so i need you guys help.first of all i budget is less.

now will it be better to use a 10 inch woofer or to use two 6inch woofer,

can a sub woofer be used instead of a woofer or is it better to use one sub and woofedr in parallel.

i have a mid range from dainity it good it is 5 inch.

i need to build a cabined with 2 or 2.5 feet height and may use 2x6inch or 10 inch

one mid and tweeter please suggest which configuration will be better....also please help to design enclosure

I'd personally go for a single larger driver rather than two smaller drivers.

Are you going to use a passive or active crossover? If you are going for passive, you may want to read this.

I'd also get a few books: Link

The guys on the Parts Express Tech Talk forum Techtalk Speaker Building are great about helping people with a speaker build. Tech Talk is almost entirely centered on speaker building. If you post over there, you'll probably get a lot of help. There are also a lot of proven designs available for your building pleasure.

i will be going for a passive crossover only....my aim is to build a mini tower sepaher system as show here Page Redirect

but i want to use 6 inch instead,then can i use a subwoofer ,a woofer a mid and tweeter to cover whole freq band.

is it good to go for a closed enclosure....i dont know hoe to tune a vented enclosure ,is there any good softs for that,

i thanks for that techtalk speaker building

Do a search for and download WinISD. It will get you a box size in either sealed or ported once you know what drivers you'll be using.

oh thanks mike,i was unaware of that,let me download winisd. let me ask one thing all this softs shows the min required enclosure size right, can our design go more that that size without loosing BASS

 

[fatmarley]

This sealed or ported calculator is a handy tool.

WinISD is good because it saves all your driver info and makes it easy to compare different drivers. I use this online calculator for quick checks. I don't know why but you have to put a '0' in front of (QTC): .707 to make it work.

If you don't understand what QTC means, read this.

thanks fatmarley,

now suppose that i have found the required volume for my driver to give the required response,then can my enclosure volume go beyond that

 

[fatmarley]

Why do you want the enclosure to be bigger than the one required for your driver?

 

[vishnupg]

actually my fried needs a mini tower design and he is low on budget. So i am planning on an enclosure 3f height and 8 wide 8deep.

 

[Inductor]

Doesn't answer the prior question.

 

[vishnupg]

what i meant was that the enclosure size will be as mentioned above but the required volume for my driver is much less that the volume already in the enclosure...

is it ok to use that enclosure

 

[Inductor]

What driver?

Generally no, but if the difference is no more than 10% then there shouldn't be any problem.
But I think the easiest way to solve your problem is to sand fill the bottom of your box until you reach the correct volume.

here my only choice for driver is a brand called dainity.it is best one available in south indian market.

their subwoofers are really good.

can i used these subwoofer as a usual woofer. 2 6inch subwoofers in parrel

Thanks giralfino

 

[fatmarley]

Can you post a link to the drivers you intend to use?

If the drivers are any good there should be an online specification sheet somewhere (usually a PDF file)

 

[mikejennens]

I would recommend building the box according to WinISD. If the box isn't floor-stander sized, add a false section to make it look like a floor stander. In other words, make a floor-stander (the height you want) with the width and depth recommended by WinISD, then add the bottom panel of the speaker at whatever Win ISD calls for.
Win ISD will give you an idea how much bigger you can go beyond the initial recommendation and tell you what the box will be tuned to.

yes guys this are the drivers that i intend to use...so i want 5.1 system

i have selected these full range for my fronts and rear speakers Iwai Electronics Pvt. Ltd.

and i have selected this woofer for my sub Iwai Electronics Pvt. Ltd.

i need the fronts to be atleast 2ft tall this will give a tower like appearence right?

then what is the normal configuration for mid channel....can you please suggest

should i use a full range as above or a mid range or mid bass ones...please suggest a example driver
