Here is a preamble to this build... http://www.hifivision.com/diy/22712-volunteer-needed-2-way-diy-speaker-project.html
Apart from being a good platform to share knowledge, this collaborative build is an opportunity to discover local alternatives to the expensive imported components for an Indian DIY'er. My previous builds gave me confidence in the locally available options and I will share details of my findings in this thread.
These were my design Goals when I began this project
Halfway through my MTM build, I collected these beautiful 5.25 inch 4 ohm Kevlar drivers manufactured by Peerless India. The model number is M13 KH. They looked good on specs as well.
Pics of the woofer...
I had these Peerless India 25mm aluminum cone tweeters with me - Model number is T25 AN 06. With an Fs of 1250Hz(measured), looked like a good companion for the mid woofer.

Enclosure Choice
----------------
For ease of construction initial plan is to go for a forward firing ported enclosure. It allows a bit more freedom for speaker positioning - especially if need to be be kept closer to the back wall. An LF cutoff below 50Hz is targeted to allow a smooth transition to the sub woofer.
Driver alignment
----------------
After making the MTM stand mount and using as a main speaker, a simple TM (tweeter-midwoofer) configuration seemed like an ideal next choice.
I got both drivers from Varsha Electronics(Jeetubhai) in Mumbai. They have confirmed there is stock of these drivers and agreed to ship them individually. I will post driver costs and other details once it becomes available.
I will post measured driver specs and the construction plans later.

These were my design Goals when I began this project
- Easy to construct and finish.
- Use locally available components to match the quality(and finish) of speakers that cost much more
- Balanced sound output suitable for unfatigued music listening
- Good integration in smaller rooms and with sub-woofers
- Small footprint and WAF

- It could give almost the same low frequency extension as the MTM in a suitably sized enclosure, hence can be used as main speakers in a low power Home Theater setup as well when paired with a suitable sub woofer similar to this build - http://www.hifivision.com/diy/19965-my-ported-subwoofer.html and http://www.hifivision.com/diy/22681...ss-driver-available-locally-2.html#post317859
- It can be used as a vertical TM center channel speaker, resulting in good tonal balance between the mains and center since all use identical drivers.
- Owing to the good sensitivity of the drivers, should work well with low power amplifiers (50w) for moderate listening levels
