Thanks!

I will be getting the Woofer & Tweeter from www.mass.com.au.
The only problem is the price, Its going to cost me AUD $270.00 just for a pair of Woofers and Tweeters.This is a bit too expensive 4 me, one thing I would like to ask is whether you could post up the Woofers and Tweeters u would choose if you had a price limit of AUD $200.00

Audax, TM025F1 TWEETER 25MM HIFI ROUND TEXTILE (MICRO)

Those are nice tweeters. If you are looking at that one you should also consider the TM025C1 which gives away some sensity (you won't have to pad it as much) for a really compact form factor* (and a little less $$$ if the CAD prices in the pictures are any indication) or for the same money the TM025F9 which has a slighly smaller faceplate (so you can get it a bit closer to the midbass) and a slighly more extended range at the bottom.

* might be small enuff that you could consider mounting it co-axially.

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


Note: the missing specs on the right are the same as the one on the left

Thanks!

This has been a big help.Are these prices in AUD$, if so I will be getting one of these models, but which one.Because there is such a small price difference, which one would you take.I really dont know which one to choose!!!

Jeroth
BTW, where did you get the pictures and prices from?😕

These prices are in Canadian $$$, which are close to the Oz $. If i had to pick i'd get the one with no mounting bezel, next choice would be the one with the flattened top & bottom

BTW, where did you get the pictures and prices from?

Snapshots out of the McBride Catalog.

Is a BASS MIDRANGE the same as a woofer because they dont sell any woofers on the ME-AU site that are under AUD$150.00, all of the ones that are within my prive range such as the AUDAX HP170Z2 6-1/2" are classed as a BASS MIDRANGE.Can any1 help me on this 1.

Jeroth
 
Yes the woofers you refer to are generally not suited to reproducing midrange material. Something like the **170Z* with the HD-A cone are nice drivers. The 'bass midrange drivers' are what you are after. I'd specifically suggest the HP170Z2. I'll let the other guys tell you the rest of the story.
 
OK

Thats fine because I dont intend on buying ready cut boxes off the net anymore, I am going to buy the wood and get it cut to the rite dimensions.So what type of box would be PERFECT for these speakers?
Is there any1 who could post up a design or a link to a box design that would suit these drivers.

Thanks,
Jeroth
 
Using the WinISD calculations you end up with a box:

12.11 inches wide
18.48 inches high
07.78 inches deep

These are internal dimensions with a box made from MDF 3/4 inch thick.

The vent is a 2 inch tube 3.08 inches long, tuning the enclosure to 52.44 Hz.

Here are the metric values

307 mm wide
469 mm high
200 mm deep

MDF is 18-19 mm thick.

Vent is 51mm diameter and 79 mm long.
 
that box is pretty tall and not very deep, that could be something worth changing but seeing as i dont have a calculator and only one hand i cant do it.

25mm Mdf may also be an option, its marginally more expensive and will reduce vibration.

Anyone got the programs to run a crossover?
 
If i made it shorter by, say, 3 in, would i add these 3 inches to the depth of the enclosure, or is it more complex than that.Thanks for the warning about it becoming an obsession, but i think its 2 late(even though ths will be my 1st project).

Thanks for EVERYONES help, it is greatly appreciated.I am just happy that I have finaly decided on drivers.

Now its time for the cross overs.Any ideas any1??😕

If anyone could help with a crossiver, it would be appreciated because I hane no clue how to design one.

Jeroth😕
 
Are you looking to learn to build them or would you prefer someone to do it for you??

If you would like to learn here is a great article
http://www.the12volt.com/caraudio/crosscalc.asp
and this is Andy Graddon's site,
http://home.iprimus.com.au/gradds/
It has all the info you could need on 1st order series Xovers.

We will also be happy to verify any values that you come up with, ie, post what you come to from those articles and we will tell you if you are on the right track.

PS - Sorry if i am a little slow in my replies, i am typing one handed as i broke a knuckle at hockey last night.
