For best results, MTM configuration should work. Buy D25 Ag 3506 tweeter & P 17 wj 00 08 woofer, it's made up of polyproplyne cone best for midrange reproduction. They also sell crossover components. Always offset the tweeter from the center, one way to reduce baffle diffraction. It may cost you 23k to build with double layer front baffle. Results are exceptional with detailed mid, highs & lows. If you want more info, i am happy to provide you the MTM drawings with crossover details.

All the best, Anil

Hi Anil,

This is so amazing, that you doing, building your own speakers. Great Job man !

Do they really sound good ? or they lack somewhere compared to the branded speakers in the market. Surely there would be slight difference but if its not all that apparent then I guess its perfect.

Anil I really really want to build my own speakers from the scratch though I have no experience in any such venture ever. Could you suggest some books and websites to get started. I checked one website but then it was american site with drivers available there and all the circutry, which offcourse would be of no help to me.

Do you think it will be a waste of time and effort for me as i don't have any electronic background, is that necessary ?

I did check the corroson website that u mentioned here. Sorry forgot to mention, I am in Delhi.

Thanks
Aryan.

Thanks Aryan, sorry for late reply as i was out of town. Yes they really sounds good. I did collect lot of data on speaker building. These are low end drivers, but sounds good compared to other cheaper chinese mass produced stuff. The best ones are SEAS drivers with phase plugs, very are expensive & not avilable in India.
If you do not have tools & experience, a good carpenter can build a good enclosure for you. Regarding crossover it's very simple. You can get the Inductors wound by Corrson, they do the job for you only u have to assemble occording to xover diagram. Diy is a good hobby it does not require any electrinic background, know few bacics thats it. Check out DIY section on good bookshelf speakers using vifa drivers.

All the best, Anil

Hi to all,

Anil Kumar and Vivek phadnis wow. Congratulations to both of u. From what i know its takes a lot to make a good speaker and u guys seem well on ur way.
If u guys ever really make it big and want to go public with an IPO please contact me. HA HA seriously great to see DIY stuff. I guess the joy of creating something is totally different from just going out and buying stuff like most of us.
Regards and good luck

Here is my latest creation. Two subwoofers with Infinity car sub drivers. Each driver is rated at 300W RMS, 4 ohm. Right now I am using it with an 80+80W amplifier. I plan to build more powerful amps for these babies.

Hi Vivek, congradulations.

Thanks Anil. Do you know where I can buy amplifier kits in Bangalore? I am looking for something like a 200+200W one.

thanks for the info anil. can you give me a rough break up of your cost for your MTM pair? .i cant figure how it would run upto 23K. given the cost of the components and the enclosure made of particle board or mdf? how much did you spend on the 2 Linkey Xovers?

great work by the way. congratulations! i can imagine how much you must enjoy these speakers every day especially since you built everything yourself.

thanks a lot

vivek,

great looking box. i thought you were going to use seperate enclosures. one for each sub. i am guessing crossover inconvenience? thats a sweet box though.built it yourself? is that black fabric or laminate? 80+80w means per channel or using seperate amps for each? and did you make the crossover circuits? is the box sealed or ported? i am guessing sealed!!

i tried using 2 old pioneer 800w dvc car subs and drove it with a stereo 200w/channel amp(denon i think). those were college days so no patience for Xovers.

i used each sub with the two 4 ohm coils in series to double the ohmage. i tried the famous "deathbox" original design when it was still free. i made 2 of them. the sound was maddeningly loud and shook my house. the old denon blew one day so i sold 1 sub and used one for my car.

post more pics with your present amp.
good luck with your design.
keep us posted.

Hi Vivek, contact Mr Siva from Corrson, he should be able to help you. He had a couple of 80 watt pc boadrs imported from Australia.
