Carry on friend.

If it is okay for you, please share your process of thinking to select this speaker.
It will help us when any of us take the same route.
 
A small diversion to the project, i wanted to try DIY Spikes also.

I went to the lathe machine workshop nearby, and gave my specifications and directions.

Below link has photos of the final product.

https://picasaweb.google.com/108964908220887375691/DIYSpikes

Each one costed me around Rs.65/- so the total cost is (8 x 65)520/-, I will collect rest 7 spikes by tomorrow evening will post the final pic of all 8 tomorrow.

I am afraid if the lathe guy makes perfect spikes same as the sample one I have with me.

Thanks,
Hari

Hey..to be specific there is no special reason for me to pick these drivers.

I picked these drivers with in my city from fellow DIY'er goldy.

These can be used for MTM set-up.

Thanks,
Hari

Today evening I got all the 8 Spikes..:yahoo:

There are some mismatches in the sizes, but they can be definitely fixed while in the process.

The picasa link has the updated pics of all 8 spikes.

Lets hope best..!!
 
I hope you have estimated for enough space between the speakers and rear wall. Bipoles typically need to be at least 3+ feet away from the rear wall.
 
Good work so far.. what are your plans for Xovers? Call me, I would tell you a guys number who makes inductors for you.

all the best.
 
What finish are you going to give for the spikes?

Did you missed out the disks for the spikes?

I am planning to insert them into a nut bolt..!

which will get fixed into MDF thick slices.


I agree they may not have perfect finish..! but i will try to expose them as little as possible and they do their job..

:confused:

KC - I am planning to keep a distance of 1.5 to 2 feet away from wall. Would that not be sufficient.

Thanks,

I met goldy he shared his ideas and opinions on the bi-pole idea.

Pros and cons .... and practicality for a new DIY'er like me to take up bi-pole.

In simple he told you can't achieve what you are thinking off...:-)

We had a very good discussion ...fianally i gave up the idea of bi-pole.

So except the backfiring drivers my towers will have the following:

- 2 12" Passive radiators
- 1 12" Subwoofer
- 1 Tweeter
- 2 4" drivers of peerlessT

So far i have all the required drivers to start the project, only thing that is pending are the passive radiators.

Tomorrow the hunt will be on for passive radiators DIY build.

Thanks,
Hari

Hmmm, tell me something, why this design?

Reasons for the build...

1. One sub for each tower so total 2 subs which should generate a decent and perfect bass.

2. I don't have to bother about the placement of subs and also no extra space for subs.

3. Passive radiators can reduce the size of the cabinet to a great extent, and i think PR's can help in tuning the subs well compared to ports.

Thanks,
Hari
 
Now all the drivers required for the project are ready :-)

- 2 12" Passive radiators
- 1 12" Subwoofer
- 1 Tweeter
- 2 4" drivers of peerless

So my first Step 1 Driver Collection is complete.

Now next start Step 2 Cabinet Building
