My first DIY speakers

May be it's a trial version. Looks good. Where did you get the design? is the cabinet and xover made occording to driver specifications?

Regards, Anil

Yes. The drivers were all measured with help from a friend. He also helped me design the crossovers. They are Linkwitz Riley. Fourth order for the tweeter and I think second order for the woofer. I have written it down somewhere. I will check and let you know. The woofers are in parallel and have a zobel network. Effective internal volume is about 44L.

Are you using your speakers for HT or just music?

I am building two subwoofers for HT with Infinity Reference 1230 car sub drivers. Each will be housed in a separate box and will be equalised with Linkwitz Transform circuits. The boxes are still under construction. I am aiming to achieve 35Hz. I wanted to ask if you know if inexpensive PA amps are available to power my subs or do you know if any amp kits are available. I was thinkig of building two amp modules but there is a big problem of fake semiconductors in the market. So I need to be careful.

Good work, one more DIY enthusiast in our list. I am using this speakers for music. I also have Tannoy fusion 2 bookshelf speakers. I recently added YAMAHA CA-610 (1979) and Pioneer SA-9100 (1974) to my
amp list, both sounds wonderful. Regarding your sub amp, you have to procure it thro ebay.US or Parts Express, they are excellent. Good subwoofer amps are not avilable in India for DIY use.

Anil

good, How much did it cost you. what about cabinet construction and materials

Ash

The woofers cost me Rs 1620 each. The tweeters cost about Rs 1200 each. I bought a 4 feet x 8 feet sheet of MDF and built the box myself. Plus the cost of enamelled wire for the coils and polypropylene capacitors, all cost about Rs 1000.

What is the thickness of front baffle? P17 sounds better than Tc18 because of polyproplyne cone, mids sounds better and can go down to 37hz. Initially i designed Transmissionline speakers, i did not like it, later i changed the design, built a bassreflex enclosure with 3 braces to minimise standing waves and vibrations, tuned to 40hz. Post few more closeup shots with xover.


Anil

The front baffles are 18mm thick. I have not used much bracing actually. As you can see, the speakers are still unfinished. Maybe I will do it shortly.

Double the front baffle, sandwitch two 18mm MDF for better performance.
Internal bracing is a must for tower speakers. I would like to audition your speakers. Please mail me your contact# to anilmn@inbox.com.pk

Regards.

I have begun to dismantle my speakers for more bracing. And I also need to finish the cabinets.

I have downloaded lot of articles and write up on DIY speaker building.
I have done lot of home work before building my speakers. I do have a very good article on bracing and alignment of inductors in xovers, if you want i can post it.
