Can DIY SUB match Professional SUB in Market??

[sarith]

I've used dual opposed subwoofer with 8" woofers back in late 90's. It was really good compared to it's size and power. The box was made using jackfruit tree wood with internal bracing and glass wool damping.

Unlike normal boxes, this box was made a little longer and taller for 8" woofers. This sub was particularly good with explosions. I loved testing it with 'The thin red line' movie.

A sub is far easier to do successfully using the DIY route than 2 or three ways.I think a little research on the net will answer most of your questions in considerable detail. Types, sizes, driver options, construction methods used, costs, user experiences etc.

So of these which are your top preferences? Please rank and state why.

I was wondering if someone can answer this question. For a subwoofer that is available at 500 dollars at svs sb1000, what would it cost in material cost to duplicate its performance. And how much time will it take to build it. That will really help all of us who are thinking of building our own sub to save money.

The answer to your question is not exact. If someone like me had no way to bring a sub in checked in baggage from the US I would have no option but to bring a driver and build my own. If I was in the US I would have many options to pick up a pre owned sub. Most mfrs use around 50% or less as input cost the rest goes towards R & D, profit margin, dealer margin, shipping, advertising and promotion etc. Now if you get a good preowned unit at half price things get a lot more interesting. Having said that, a sealed sub is perhaps the easiest type of speaker to build, and you will get a huge bang for your buck.

I forgot to mention that the said box was a sealed one (no port).

The standard trick for those Bass monsters in my area is to get a high power high sound quality car sub and put ti into a massive braced box and power it with ungodly amounts of power.
XXX RE 15's, Rockford's P3's, JL's etc etc are all in houses powered by crown's, Yorkvilles and the like.
My friend has a sub that skates across the floor when you play. Every week or so, he has to reposition it.
Home made is better IMHO.

Cool.

I have build two DIY Advanced TL sub one with a 5.25" driver (passive) and other with a 6.5" driver (Active) and both had exceptional low end, tight uncompressed bass and had very good integration with main speakers.

Could someone please answer the question? If you have not built a SB1000 equivalent sub, you can take any popular sub and let me know how did it cost to build yourself and how much time did it take?

I am partial to TC Sounds for VFM specifically their LMS-R subwoofers.

For amps I am partial to the Keiga KG N D-52100-5P . The Yung SD500s I imported all failed so avoid them.

TC's new RipCurl Amps can also be considered.

I don't know what one considers a "Professional" sub but the TC/Keiga combo can rival most commercially available subs in the same price range and maybe more.

IMO,

a properly tuned and properly powered DIY sub could beat subs available in the market. for the drivers there are numerous car audio subs available, in fact I am myself using 2 Pioneer TSW1208D2 car subs in my system, make the box right, tune it right, it could sound great. but, most car subs are not that efficient.

my advice would be using a Pro audio driver, 15", 18" subs could produce really high spl levels, also maintaining the tonality at the same time if properly tuned. these are good, efficient and also cheap options. have a look at these, decently priced and pretty good specs:

the amp could also be a DIY, if you have the skills, to make a 300-400W amp, dont have to bother much about distortion, after all it needs to be a sub amp, for 20-200hz freq range.

It is doable and not so very expensive. You need a good 12" driver like Eminence lab 12 which is available in india so so need to import.

Get a good quality used amp 200 to 300watts rms.

Make a sealed enclosure.
Get MINIDSP or any active crossover kit which can be connected to pc for equalizing .

You are good to go, and it will sound tons better than any branded sub woofer in similar price range.
