@trittya
you have mentioned about different materials for the cabinet. Does the sound get impacted depending on the material.
Dear Joseph,
The three materials I recommended are MDF, marine-grade ply and Baltic/Russian birch. AFAIK, there is
NO perceptible sonic advantage
(IF ANY) of plywood over MDF.
Some of the world's best speakers are made of MDF but it has to be braced with HARDWOOD. Therefore, sonically they are all at par. Now, structurally speaking, I would prefer ply over MDF for longer/larger/taller cabinets beacuse of two main reasons, one is that structurally, GOOD WELL-BONDED ply is marine grade ply (say, novateak) is superior in the long run as it is much less susceptible to expansion and contraction due to absorption/loss of moisture due to change in climatic/humidity conditions in most of the Indian sub-continent. The third option, Birch Ply would again be overkill for home-equipment. Firstly, its very expensive, about 4 times that of MDF cost and about twice as much as good marine-grade ply and secondly, its not really needed. Pro-audio folks use birch, NOT because of any sonic advantage but because of its durability, as the equipment is bound to get tossed around from venue to venue, one installation after another. Again,
NO sonic advantage over the other two.
Sonically, the most
exotic ply would be bamboo-ply which is highly weather-resistant, too, albeit not as much as marine-grade ply. The problem lies in getting it in the appropriate thicknes, but if you can, nothing like it.
BTW, one of the largest dealers in bamboo ply in India operates from Chennai. Details here
Marine Plywood,Flexible Plywood,Bamboo Plywood,MR Plywood,India
Here, you should be able to get all that you want and more incl pre-laminated/veneered MDF,HDF or all kinds of ply incl BWP(Boiling water-proof) ply
(of course, for speakers that would be OVERKILL)
IMHO a decent(or competent ) carpenter should easily be able to do it,provided the drawings are good. This isnt rocket science.
As Mr. George stated, a competent carpenter can do a good job. Even if he does not have experience in making speaker cabinets, the flat pack can act as a reference for him to make the balance stuff as drawings are already available.
Yes, a
competent or decent carpenter can make a good speaker cabinet, but you see, firstly, those two terms are clearly relative and not absolute and secondly, rocket science it may not be, but craftsmanship it surely is. There's another way of looking at it, LOL, there used to tooth-extractions by pavement-based "dental surgeons" before we had dentists touting their BDS/MDS degrees. Different matter that it used to be done with a pair of pliers and NO anesthesia. Though, I seriously doubt whether any roadside dentist could do a ROOT-CANAL-TREATMENT.
On a more serious note, if that gent/craftsman/wood-worker can give you a SONICALLY INERT/DEAD cabinet with proper bracing and sealing, then you are safe. The only point is that a craftsman who has made cabs before is aware of the crucial implications of the finer nuances, so its better, naturally.
I suggest, although I am not part of the build is that, Chennai-ites go to the out-sourced woodworkers of someone like Mr Mark Murugesan of AUDIOCRAFT or Mr John Thankachan of TORVIN, while FMs from B'luru/Hyd'bad can do likewise with those of Mr Siva of CORRSON or Mr Arasu Kumar of LAYA. Mumbaikars/Pune-ites can do likewise with Mr Rajeev D' Souza of LITHOS or Mr Vikram Joshi of RAAGA PROSOUND. Now where does that leave my brethren from Delhi? Well, Woodstock closed down shop long back but there are expert cabinet makers still around in and around Lajpat Rai Mkt as well as the fact that its worth finding out from Mr Nishi Mohan Nakra of ENBEE(since retired) as to where/from whom he used to get his cabs made. FM Parora spoke to him once in NOIDA and may be aware of his contact details.
Methinx it would work out better if the kits are shipped to their respective owners for getting cabs built locally/nearby as per specs/plans. That would save a lot on shipping the finished cabinet, too.
Anyone in North India who cant find a good cabinet maker can get i touch with me and tag along as I am going to get all my cabs for my
LINE ARRAYS, Di-poles and down-firing sealed sub-woofer with a 21" driver made from FM Kanwar's woodworking lines. Now, thats an invitation, not a request, lets be clear on that. I, for one, love both mu music and my money and would not throw my hard-earned cash on something that I am not sure about.
At the end of the day, Gentlemen, the bottom-line to
all members in this group buy-n-build is that, its your money, your kits and your cabinets. So, the choice, too ought to be yours.
The only reason I wrote so much here is that I'd hate to see/know of a FM who is not happy with what he has acquired.
Enough said.
Wishing all of you the very best for the project.
Warm Regards as ever
