need help two way

[sexya]

hi
i'm building a two way speaker for my stereo and have bought dayton classic shielde woofer - 5 inch one and hivi dome tweeter - tn25
this is my first attempt at speaker building. I need all the possible help for the same and it should be a simple build.

Good, now you have complete series model for the woofer. Do you know how to use WinISD software for the speaker enclosure, for a start. (On tweeter, you mean rec. xover freq. >2KHz).

i'm completely new to speaker building, i do have bass box and winisd so which one to use, and i dont know any thing of crossover etc

The above is the calculations for your passives.
As a start, I will use 3000Hz as the cutoff points for them(considering tweeter should be X2 from its FS to be safe) and see how it goes.

you've got some reading to do

Designing Crossovers with Software Only
FRD Consortium tools guide

overwhelming? sure

It is difficult (near impossible) to find speaker components in Bombay.

Here are the cabinet dimensions:

Now, we just need a series crossover--only two inductors (one per each speaker cabinet) to find or make or ship at great expense.

Here is the tweeter:

Here is the woofer:

Parts-Express.com:*Dayton DC130AS-8 5-1/4" Classic Shielded Woofer | woofer dc130as-8 5-1/4"woofer midbass shielded woofer dayton dayton audio dayton loudspeaker

I attempted to convert the super-spendy parallel crossover (made of parts that cannot be sourced at market) on this page: http://www.speakerbuilder.net/web_fi...P/dayschem.jpg to a series type crossover to reduce expense and make it more doable.
Attached is my guesswork; but, can someone put in the correct component values?

After checking on the box size I would go testing the xover similar to this
(L=>1,5mH, maybe 1,8/2,2mH on woofer), in the end I would adjust right padding on tweeter.

Pay attention (with max. power because) you will have (Xmax=2.5mm) cone excursions about double spec with only 20W @60/70Hz.

I have used the TN25. I found it to be better than the price would suggest. A touch grainy, but quite satisfactory. I failed at my attempt to solder wires to them. I melted the sides of the enclosure, that is all.
