AV Rack in chennai

Any Idea how to build A simple DIY speaker stands, for Bookshelves with Parts available in and around chennai, It would be helpful for me as well as many who can't afford expensive speaker stands available readily in the market.


Thanks

Sure Saran,

This is a stand I made a couple of years back for a pair of Kef Coda 7s. It now serves as a stand for the holy basil after I got in my floor standers

Here are the details:

The base and the top are made of MDF. The stand actually a 5" dia PVC tube you can pick up at any hardware store. Since the pipe is hollow I had filled it with river sand (you can take them for free from any construction site, of course after requesting the security guy who is around). The sand helps is additional damping and isolates the speakers placed on top. If you want more ooph factor fill it with talc. You can paint it whatever colour you like. I opted for brown as they complimented the Coda well

They rival any top quality speaker stand and it is truly amazing. MDF is an acoustically dead material, PVC does not resonate (several leading speaker manufacturers use PVC for bass port) and river sand helps it further.

Coat of making a Pair less than Rs 900

MDF boards= Rs 450
PVC Pipe= Rs 120
Resin, glue, bonding material = Rs 80
River sand = Rs 15 (tipped the security guy for a tea when he started 'scratching his head')
Painting = Rs 150

All the best doing these! I am sure they will rival top brand speaker stands with regard to quality, purpose, aesthetics and not to mention cost!

flanker and venkat, thanks for everything,

In case many members would want it and you would be kind enough to do it for us. Can you us give an idea how much it will cost with shipping.

I just got my rack made by a furniture company for 4.5k.(was a friend am getting him a vanguard wall mount for that price)

I got it made from rubber wood. I did not know flanker will come late in build. (just joking)
this is how it looks

I was thinking why can't a pentapod be done like a tripod. we have three on the front and two on the centers of the back and one long plank for all.
Thanks.

Good job pradski,

I see a turntable. Where is your phono amp? Clearly your AV receiver won't have one. Also with your centre speaker on the rack, its not good for your turntable (or even your cd player). I think you should mount the speaker on the wall and place the TT on top

Another thing thats evident from the photograph is that your racks have already started sagging. Do look into this

Build yourself the flexy DIY rack. You will enjoy it. Your existing rack would serve very well then as an excellent CD storage rack and with a few modifications even as an LP rack

I think you should still build the flexy. Would be glad to assist you.

Pradski, give m a little time. I shall enquire in the market for prices of the pieces, and check with some transport companies for ground shipping. I also have to work out the exact weight for shipping, I shall coordinate with Flanker, as I am very impressed with his rack.

Cheers

flanker,

I just got this rack two days back. I noticed that he has made it uneven. ( little angry with that).

About turntable, I wanted to keep it on the top. waiting for completion.

Centre speaker, there is no place on the wall.

This is how my wall is, any idea how to go about centres.

I am interested in the flexi, even venkat has promised to help.

Thank you venkat for your help to all of us.

Hi Flaker / Venkat,

I have a question regarding my woofer placement.

I have placed my Velodyne VX-10 inside a Cupboard. I intend to add a shelf above the woofer for placing Power Supplies and UPS / Or two shelf instead to place DTH & DVD Player. Shelf shall be made of wood I have attached the pic. hope it gets loaded.

I have read somewhere, woofer sounds better placed inside a closed place. It is indeed. but i want to know if it s the right way and how could i make sure the vibrations are not harming what ever i place in the shelves above the woofer.

If this is not the right place to keep the Sub, would it be ok, if i remove the lower shelves in your design and PLace Sub there below in it in the floor.

I am intending to go for Bookshelves on Stand. I shall use your design for stand

Thanks in advance

regards,
Prasanna KV

Prasanna:

It may not be a good idea to place the sub inside a cupboard. Unless the cupboard is very well made to handle resonance, the cupboard will generate collateral vibrations and noise.

In addition, keeping electro-mechanical devices such as a CDP or a DVD Player on top of the sub is a bad idea. Unless you can create very rigid shelves that will absorb all vibrations and not allow any to be transferred to the devices, it will create resonances that will mar the performance of these devices.

Cheers

Hi Prasanna,

I really don't know where you read that a sub-woofer needs to be placed inside a cabinet. It is completely wrong. It needs to be placed away from from equipment. It needs to be placed at a location where it performs at its best. Ideally, this is the easiest way to find where to put your sub

Place the sub in your listening position and play some music with good bass content. Walk around the room while listening. At some points there will be higher volume, some points deeper bass and some points complete lack of bass. Place the sub in the place where you got deep bass extension. Sit back and enjoy the best performance your sub can give in your room. Also experiment with the 'Phase' switch and see it bass improves

Hi Prasanna,

Corner of the room, open air, place a mat or something under it if it dances/moves too much due to the vibration. Corner of the room with two walls flanking it is usually the best place for a woofer especially if its a passive one. Active will thump out anyway since it will be powered so placement is not as much an issue for an active sub as compared to a passive sub. Generally recommended to place to the right or the left of the center and front left and right speakers against a wall i.e. corner of the room in line with the front left and right speakers and the center speaker.
