Building speaker with surprise inside.

You will still be able to smell it
Police still check them.

Hiding pot in speakers isnt a new idea

>>1024562
Well I am not high profile person, and living in shady area, anything else you suggest tho?

>>1024562
gave me the idea of sticking weed into water proof bag and putting it into water cooling reservoir in pc case while using pastel dye since that stuff usually is non see through.

>>1024558
just make it like you would a normal cupboard or drawer. how ever, keep it sealed from where speakers will be. youll need tight tolerances or something to absorb vibrations or shit will shake open

>>1024564
Try this or a variation of it, it works although as has been pointed out, if the cops bring a dog you are pretty much fucked.

BTW speakers are a terrible idea, police always check there, and under kitchen cabinets too, best I ever saw was a guy who glued magnets under a window on the outside then got a small box with more magnets and put it in there.

>>1024711
Well that is one way of hiding your shit, but I guess there is no way of growing anything this way.

>>1024711
thanks for a tip

>>1024566
I don't smoke, but this would probably be one of the best ideas I have seen, so long as you don't fuck over your computer.

On that note: Fake hallow waterproof rock, castle, ect inside a fish tank might be a good idea.

>>1024711
If you use a hallow door with something that smells strong, and you store it there all the time...

I did this with some peanut butter cups for the lolz, a few days (maybe weeks) the door smelled l like peanut butter. Like just walking up and smelling it.

>>1024730
yeah you need an airtight container or as airtight as you can get it, bottle blanks are a good one.

>>1024737
Was like 10 tho, building all sorts of shit, I think it was after Halloween as-well. I think I put a Lego man in it next because my mom complained.

>>1024736

Yea I guess that would work

This is a good one if you have the right kind of door

>>1026170
What the fuck are you trying to say?

>>1024558
I build speakers. Whatever you need just ask away

>>1024566
The warmth would ruin your weed

>>1026406
I plan to put 25cm sub on the bottom of each stereo speaker add 100w built in sub aplifier for each and for top I am not sure if should go with 2 way or 3 way splitter. Should sub area be isolated off rest of the speakers? there will be large pot between sub and speakers on top. Should sub area have resonance pipe as well?

>>1026503
Not him, but in my case I will obviously install LED setup. probably my own design, and probably will install automatic PH system for DWC.

>>1026555
You could go 2 or three way, either sounds good. The sub should be isolated, and it should have a resonance pipe, called a port. Do you already have a subwoofer driver in mind? What are your space requirements and budget?

>>1026561
I will use pre built sub panel.
Going for as cheap as possible setup, but with manageable sound.
I assume speakers case have different requirements than regular furniture, will plywood and wood glue be enough? I got used to making furniture for myself, but never glued stuff.

>>1026566
plywood, glue, nails, and you should probably get yourself some walmart veneer to cover it. can you link the sub?

>>1026567
Well I am not from the US and it is from local auction.
It have phase,crossover, volume regulation and lo/hi input.

>>1026569
do you know the name and the price? it might be easier and cheaper to build your own

>>1026572
around 75usd
there are cheaper ones, but without phase regulation and only lo input
also brb 2h

>>1026572
OK back if you are still around

>>1026621
if you are able to give me the name of it, it would help out a lot.
I can design the speakers for you, but what would I have to consider for what you are putting in them?

>>1026621
also what power handling requirements do you have?

This is pretty much no-name stuff, called sub-200
Here can see circuit from auction
So far I have been satisfied with 30 yo apmplifier and 2-way stereo 35W
I plan to listen to buy amplifier later after building speakers, most likely will travel to shop and use own speakers for tests, anyway the thing is: I do not plan to play sound excessively loud

>>1026627
alright that actually looks pretty high quality. There can be space for the grass in both the sub section and the main speaker section or just one. how do you want it

>>1026635
OK there will be single big pot in the sub section, planning to face sub to the ground and between sub box and upper part 25x25x25 pot filled with water (DWC) will be installed, columns will have about 150cm height.
Not sure how much space should I leave for sub section (and I hope sub wont destroy god damn pot)

>>1026716
>>1026729

it looks a lot taller in the pic than it actually is cuz i modeled it wrong

anyway heres the fixed version

>>1026716
the other thing is that the upper port must be 9.6 cm long.still cover it with thin black felt so people cant see in

>>1026733
So I should go with self made 2 way crossover + sub? and place speakers on my ear height yep?
Also what D hole is for? it is necessary to be there? I would prefer to let air go out from the top.

>>1026737
It is to tune the speakers and so your plants can get air. You can put it on the top if it is better for them just make sure it's 10.5 cm wide and 9.6 cm long

>>1026739
DWC uses fish air pump, planning to place pump in general sub area and it will go to pot adding oxygen to roots and excessive air would go trough top, using carbon filters - the only method of stopping smell.
and as 9.6cm long you mean port (pipe) length for upper part?

>>1026746
Yep it's a pipe there's one in the sub area too. I don't know how clear my drawings are. If you don't need air to go out the top, then it doesn't need a port on top.

>>1026749
crossover is tuned to speakers specification of could use other speakers of same size?
on side note they came out quite bulky originally thought that would fit within 30cm space, is it a matter of bottom port placement, maybe could place it on one of walls making possible to fit it in 30cm square space

>>1026755
You could use other speakers of the same size, as long as the tweeter has a resonant frequency of 1000hz or lower.

You could put the port on the wall to make it thinner, but the smaller you make the box the worse the bass sounds, and it can get pretty bad. I used a woofer that works well in smaller spaces and it's still less than optimal. If a 10 inch woofer isn't a hard requirement I could use and 8 to better effect.

>>1026749
Which other speakers were you planning on using?

>>1026759
I think something off brand, not decided yet, but will look on local market for parts and get them working together, also from your project I see speaker needs some free space, my idea of pot right over speaker won't make it work I assume, it needs 40cm height, and these speakers grown to over 2m tall like god damn...

>>1026766
The other option is just to put all of them in the same box with the pot sitting on the bottom. You'd have all 150cm for the pot and you'd get good bass.

>>1026768
How will speakers placement look like in that situation and what ports it should use?

also i gotta go sleep now sorry

>>1026768
Ok I am back, so it wont be a problem placing all speakers in the same case without major sound quality loss?

>>1026954
no not at all. In fact most 3 way systems are designed like this but there are small boxes built around the midrange and tweeter because they don't need the air suspension like the woofer does to produce bass.
I'll draw you up a rough one real quick so you could see how it looks.

i was workin today so thats why it took me so long sorry

also build a small plywood box around the tweeter and midrange driver. just enough to cover both of them.

when you figure out what drivers you want to use for the tweeter and midrange post the specifications or name and I can design a xover for them. it cant really work with other ones.

also the box is designed around the sub so its pretty critical that you use that one. if you have another one in mind also post the specs (I need the name) and ill fix the design. this will only change the port length.

>>1027139
also the hole in the plywood counts as part of the port's length so you'd probably want to cut it closer to 8.4 cm long because it will equal 10.4 cm when glued to the 2 cm ply

>>1027157
OK I will look after parts either tommorrow or in 2 days as now i am on phone, not best way to browse for parts.

>>1027154
I just make fast check on these speakers you listed out here to find local equivalents... they are all woofer speakers and no tweeter?

>>1027582
The big one is a woofer. The middle one plays midbass, so midrange and some bass. The small one is a dome tweeter.

>>1027590
I mean 2 smaller speakers on list are both mid woofers

>>1027591
http://www.parts-express.com/goldwood-gt-525-1-soft-dome-tweeter--270-182

Nope definitely a tweeter

>>1027667
OK sorry my fuck up, looked up local stuff, would you like to browse trough this producer stuff?
Thing is, producer have only few tweeters resonance frequency measured, and none have exactly 1.0kHz, few are between 1.1-1.3 range, if you want here is producer website, however checking for tweeter resonance frequency have to be made manually in each specific speaker as this is not listed in their catalog. Anyway here:
website http://www.tonsilproducent.pl/en/assembly-speakers
catalog www.tonsilproducent.pl/files/katalog-EN.pdf
And here is tweeters mash-up, so you can see their spectrum and resonance http://docdro.id/dyDflaG

>>1027908
The resonance doesn't have to be exactly 1K, I can adjust the crossover. I'll look at the tweeters now.

>>1027984
in catalog there is also resonance of woofer speakers, not sure if this is useful info.

>>1027985
I need some help with that because it doesn't list the size of the woofer. Do you know which ones are 10 inch? And the mid woofer needs to be between 5 and 6.5 inch and I don't know which ones are

>>1027988
system is simple:
TONSIL GDN20/30
20 is size in cm
30 is power
20cm/30w
applies for all

>>1027993
Thanks

>>1027993
Their selection of 25cm woofers isn't very good, would you be able to use a (or 2) 20 cm woofers

>>1027993
The mid woofer you should use is the GDN 15/40/30.

The tweeter should be the GDWK 9/80/1

>>1028002
Will look after different woofer producers here, tell me what I should look for.

>>1028023
Low resonant frequency, if they list more specs then lowest vas (equivalent air volume) possible.

>>1028068
Hmmm tell me what would be considered as low VAS as finding one with 48L
And how low would be satisfying?

>>1028068
Checking local market stuff...
Most of it is no name with no more specs than power and size... And ones with listed out specs have riddiculous price.
Anyway, what speakers you would suggest to use for double sub configuration?

>>1028075
>>1028083
48L might work, what is the resonant frequency?

>>1028086
Not listed... all data presented:
Qts 0,41
Vas [L] 48
Qms 2,71
Qes 0,48
There is no characteristics graph either.

>>1028086
well fuck could not find resonance data, how about this one

>>1028101
I just modeled that and it would be very good. It does look pretty expensive but it is a great subwoofer and makes my job easier.

anyways you would need to make the port 11 cm in diameter and 51 cm in length.

this would play flat down to 24 hz. the lowest note on a bass guitar 31 hz.

>>1028286
51cm port? wow that is damn long.
and single unit price is around 100usd

>>1028101
Unrelated, but could someone explain that power rating to me.
More specifically, if I feed that AES rated 300W to it at 25Hz, will it be able to handle it for extended periods of time? Do I need to pay any extra attention to cooling?

>>1028366
there are three types of power handling specifications for speakers. Electrical and 2 types of mechanical. Subwoofers hardly ever have to worry about electrical but mechanical usually is a problem.

The first type of mechanical is xmax, and that is the distance that the speaker can travel until the voice coil leaves the magnet gap, causing distortion. This is non destructive and could be used with this amount of power, but the bass just wouldn't sound very good. The second type is xmech, and that is the distance the coil former can travel until it hits the backplate. This type is destructive. At 100W (your amp's power) the sub stays within the xmax by a huge margin until about 8 Hz. If you wanted to use all 300W, its power handling would be limited to about 17 Hz. After that, it starts to distort, and a very good ways after that (about twice as much movement) it becomes destructive.

bottom line is don't worry about the power on this one.

>>1028555
Ok, thanks for explanation.

>>1028555
Hey man, you plan to design crossover for it as well? some other things left to be calculated?
Also is this "cut list" something I have to follow?
Thought of 2 larger 150cm pieces on sides and smaller 150 in fron and back enclosing top with small cap that would go slightly inside in the way to show off plywood layers as decorative element.
What part is most important? internal air volume?

>>1028563
Port size and internal volume need to stay the same. The cut sizes are for optimal sound but changing them won't make a perceptible difference. I'll redesign the crossover soon.

>>1028563
make sure to have the polarity on the tweeter reversed

>>1029035
Question: if I would like to precisely tune up capacity and inductance. Is using more than one element advised? I know I could combine few capacitors for precisely tuned elements to ones you given to me.

>>1029051
You can, but I wouldn't recommend it. If you really wanted to, you could run multiple ones in series to get the value listed.

The reason why this level of precision doesn't really matter because different factors will change the value of the capacitor and inductor, like heat. (i.e. the values will change depending on how loud it is, how long it's been playing music in a session, and the ambient temperature.

So you want to build a couple of coffin sized, speakers, that reek of weed and radiate heat like a motherfucker........ what could possibly go wrong!

You know you need a big-ass grow light, serious ventilation, and an easy way to add water witout frying everthing, right? This is gonna be way more trouble than it's worth, and unless you invest money and space on a carbon filter your room is still gonna smell like weed. It's gonna be hot, loud, and stinky. Don't do this.

>>1030643
Planned to use own design of LED setup, 30W and DWC so water supply should not be an issue.
Also I have vacuum enclosed super silent air pump that will do for air exchange and many other solutions.

>>1029818

They're also going to be full of humidity so I assume his speaker boxes will swell apart and disintegrate in addition to reeking of weed and nutes

Fuck man it would be easier to do a micro screen of green grow inside of a faux-kegerator, you could even rig a small chilled canister to dispense beer from the tap

Cool, at least you aren't completely retarded. I know you are working with the materials you've got, but consider shorter "boxier" cabinets. You'll get more yield then a tall skinny box if the plants are trained right. And ffs don't put the sub under the plants.. ..just move to oregon and grow that shit in your yard like a normal person.
