Can DIY SUB match Professional SUB in Market??

[nicenicenicee]

Dear Experts,
I have Denon 1612, and recently bought Pioneer AJ 5.0.
And i have been hunting for a sub for some time,
My problem is that all the better sounding sub are very expensive (read Rythmik / HSU / SVS / Velodyne),

Are there components available which can meet same performance ( can go low, with less noise), and also soft on my pocket.

What are your suggestions
a) in terms of Driver / Amps.
b) Where they can be sourced
c) Approx cost.
d) Guidance on building cabinet

TIA

Rythmik sells a kit for DIY but that is as expensive. Parts express sells cheaper kits. But since sub boxes are not that expensive, you won't save much. Most money is in amplifier and driver.

I've built four powered subs and if you can source the components(I got mine from the US, heavy stuff), they are an excellent option and value for money. In India Peerless 12 inch drivers are an option, they sound quite good, though a good plate amp may require some effort to source.

Why not? However buy the plate amplifier with a built-in crossover. Buy a sub and build your own box.

could you suggest brand and link you think are good?

One of the best sounding sub design is push-pull dual 12 inch subwoofer.

thanks to provide more details

Some TL line sub boxes sound great too.

thanks to provide more details

I have two very nice sounding subs for sale. MK sound, mint condition. Also made a TL line box and experimented. Sounded wonderful.

can u give detail, like which sub, which amp is used in your sub, as well if some pics

Main difference between some commercial subs and (most) DIY types is that there is no excursion limiting circuitry or servo feedback to reduce distortion. But as long as you use the right box for the sub and use it sensibly within it's prescribed parameters it should sound very good. Which a lot of good sub-drivers can easily do.
I have heard some HSU subs demoed at full blast with lots of LF on the movie sound track and it almost flapped my ears. Long term it will certainly kill my ears ( not to mention quick destruction of the ears of smaller children!) AND it sounded 'awfull' .... not distorted but extremely, and physically, uncomfortable. For the children it will be bliss. After a year of this they will probably never hear anything at low level and above 8Khz ! Automatic and permanent noise filter !
The shop assistant was extremely proud that everything in the room was vibrating .
Well, it all depends on what you want out of it!

Diy sub is a good option. you can procure driver and plate amp from FM Bijin Babu's site diyaudiocart.com he sells peerless and US make Dayton drivers and Dayton plate amps. Dayton is a tad bit expensive but I think the extra money is worth the quality. ( I never used any Daytons.)

 

[doors666]

take a look at the diy subwoofer section on the hometheatershack, you will get a good idea with a lot of pics to show what kind of subs people make

I have seen and listened to Daytons at a couple of friends' homes, they are excellent. They both used the Dayton Ref series 12 inch drivers, I dont know what they cost, but one used an O Audio Bash amp in a sealed box and the results were most impressive. The other is in a sealed box with some other plate amp and is also very impressive. Recommended!

They both used the Dayton Ref series 12 inch drivers,

Thanks Georgeo,
Could you get me specific details?

Check some here-

Will try, have some travel commitments this week, but as the previous post said, there is info on the Parts Audio site. If not this week will get the info after I return.

based on "hunch" for a TL line subwoofer. And this one sounded as good and even better than the sealed box MK Sound sub. A marked difference I noted was, this would fill the lows even from its both sides as much it will do just from the front.

See Big Famous Companys, Brands, [ Country] Makes are all not at all important what Actually matters is

The Design & Quality Components and The Very important is to keep it As Simple As Possible.

CAR Sub Drivers/ Amp for Home Theater SUB?

--------------------------------------------------------------------------------

I was just looking at some of the CAR Subwoofer drivers and amps, and i comparatively find less pricey than dayton's /TC sounds/ Peerless etc.

I am wondering, if i can use any of these combination and build something budget sub, which will sound good?

also wondering why these combination are not used generally by people to build home sub.

are they going to be more distorted?
will not be as loud as a daytons 250RMS and UM22-12 combo?
they are not going to be loud?
they will not be able to go as low?

why people are not making subs with these combinations while this whole propostion is less pricey?

Thanks in advance to enlighten me.

Andrew,
Thanks for link, but my question is entierly different, i want to technically know, how car amp/drivers are different in terms of performance and sound production than home drivers/amps

thanks to throw light if you are knowledgble on this part.

Today my need is to complete my present 5.0 setup with a good (but not very expensive) subwoofer.

I know that some brands like SVS/velodyne/Rythmik are v good, but their price is at sky. I don't want to invest that much.

but on other hand i see that there are some car amps in range of 10k and similarly car drivers which are also in range of 5k, but i am wondering if it is so obvious then why other ppl are not following this route?

is it just the blind following among ppl, or there is something which i will really miss if i go by this route?

There are some people who have actually built subwoofers for home using the car sub drivers and car amplifiers (albeit some changes to the car amps using a computer smps etc.) and plate amplifiers (dedicated sub amps) from Dayton etc., and are happy with the outcome. Look at many youtube videos which demonstrate these builds.

Your question is incorrect, it should be like this - can branded sub in market match diy sub. The answer is no.

You can choose the drivers you want, amp you want, chassis size you want. How many subs in the market can boast of a 15" or 18" driver, 500w or 1000w of power.. Most of them dont have a chassis bigger than 18-20". You can make a sub according to your needs or you can buy your sub and alter your needs according to that.

My attempt to answer the same question. Through pics taken from the internet.

All subs are DIY !

Hi Doors,
You mean DIY (if properly made) could be many times better. (now it seems i found someone who is taking it in direction i am expecting it.).

if i go in layman terms: i want to re-create something like hsu (if we take an example of an HSU :
(http://hsuresearch.com/products/vtf-2mk4.html) performance using DIY, in lesser cost. and by that i mean

a) it goes as low as 18 hz
b) has around 250 RMS / 1000 W peak
c) it as loud as 90db at around 15 hz. (hsu subs goes as per graphs on website)
d) doesn't cost me fortune, as HSU + shipping does
e) its noiseless

Now my question is:
a) is it enough to choose a driver whose frequency range is 20 - 250 hz mentioned in specs or i need to look something else? or what kind of driver i need to choose or what i need to look for in a driver which is not 300 USD.

b) is dayton 250W plate is going to be as good as hsu 250RMS/1000 Peak Power?
c) are car amps good enough for this purpose? if not what they lack?
d) are sub drivers classified as CAR sub are good enough?

I believe HSU is not a very good sub, its good for shake your walls in the movies, but lacks in the music department. a good 12" ported design should be able to get you to your goals, 250w plate amp should be fine if your room is not huge.
Car subs are different beasts. in a car, room gain is too high, so they dont need to go down low, if they go down to some 40-60hz, thats enough as room gain takes care of the rest. Also, the car subs are usually 1 ohm or 2 ohms, but ht subs are usually 4 ohms.

play around with winisd. identify a few drivers and model them, see what suits your needs.
