Sony xplod box is done

**Still learning** · 10-10-2005 12:00 PM

Here are some pics of the box i made for that 10" sony, the SQ came out pretty good for the sony the only thing that bothers me is the terminals, they kind of get in the way.I panted the box red to match the coil and put in crome ports, i also siliconed the box, so its kind of a closed/ported box, this box was made to fit into a small area, thats why its tall and wide, not deep. Here they are.....

Sony box 1
Sony box 2
Sony box 3 Sony box 4 Sony box 5 Sony box 6 Sony box 7

hmm... its not a bad little box, It has that "antique" "hand built" feel, minus the chrome and garish sony :p
i would reccomend adding a few more screws to the sides, front, and bottom just to keep it tight (the back looks like it has enough going down the sides). And iirc, ports do better when theyre on the same face as the sub, but if it sounds good to you, then it is good. :)
Speaking of the sony, im guessing the two sets of terminals are for the two coils, just remember ohm's law :)
what are u going to use it for anyway?
and just a few general questions...
To whom do those feet belong in the 6th photo?
and lastly, are u a big hotwheels fan? lol

**Still learning** · 10-10-2005 04:26 PM

Well, i took these pictures on my back steps and my little brother(10 yrs old)was in side the sliding window area, those hot wheels are his, but i play with them all the time right?????.... LOL, anyways, i thought about putting the ports on the top, but i hade no clue that where the ports are placed had anything to do with the quality of the sound? could you explane please? For where the sub is going, im going to hook it up in my little brothers car (17 yrs old). The amp is a 2 & 2, I.E 2 way (sterio), two out 2 ohms each, the sub is 300 watts RMS, is there anything wrong with this set up? Because i dont want to hook it up, and screw up the speaker. Thanks.........oh and i have all of the wood glued together, then i screwed the front, sides, top, and bottom together first, so i could put silicone in the cracks there, then i put the back on and throught the speaker hole i sealed the back cracks.

P.S.- Its hooked up to a mono 300 watt amp right now and i can here some viberating from the box and i dont know how, why, or where the hell its coming from?????

is the box making the noise or the ports? I bet the problem is the port but I might be mistaken... Are those metal ports? wood? plastic?

Is the box made to specs?

**MacLeod** · 10-10-2005 05:30 PM

You should carpet the box. Ive never been a big fan of painted boxes, they look kinda amateurish. It looks like an excellent box though. Very solid looking.

**Still learning** · 10-10-2005 06:48 PM

The ports are plastic dipped in crome, i got them off of e-bay for 2$(including shipping) there also tube like 5 inches in so they are just a little extra thing, the ports viberating? how in the hell dose that work? As far as the carpeting thing, i thought about it but then i wanted a color that matches the coil, and thats what i did, but now that i did it, i agree with MacLeod, it looks too hamemadish if you know what i mean, but i dont know how im going to carpet it, i mean the box is fully put together. So could someone explane to me the whold viberating and ports thing?

**hellohello** · 10-10-2005 08:08 PM

well, vibrating could be a lot of things, it could be the wood of the box flexing if its half an inch thick or less, the ports could be loose and vibrating, or if u used a lot of wire inside the box, the wire could be smacking against one of the ports or the side of the box...

Disclaimer: This is just what I think the whole having the port on the same side as the woofer is all about, I could be wrong, its happened before :p

The idea of having the ports on the same face as the woofer is to reinforce the sound coming from the speaker... like to keep everything flowing in the same direction, because u have those ports aiming sideways, u have the sound flying around everywhere, making it sound a lil weaker, not as focused.

As for the amp setup, its not a stereo speaker, it has to be hooked to a mono amp, or a bridged two channel, running it in stereo will most likely kill it.

**neomagus00** · 10-10-2005 09:06 PM

running a separate channel to each coil won't hurt it, but it may not be extracting the best performance your amp has to offer...

**hellohello** · 10-11-2005 07:16 AM

I remember reading that running each coil on a seperate channel was bad, since not all recordings are perfectly balanced u could have the coils doing different things and have it tear itself apart...

**neomagus00** · 10-11-2005 04:22 PM

no, it wouldn't hurt it, even if you have totally different signals going to the two coils... the two coils interact to produce a single magnetic field, which then interacts with the magnet to move the cone...

**Still learning** · 10-11-2005 04:26 PM

Ok so you suggest that i just gook it up to a sterio amp and hook bolth terminals up to the same channel? Would i get more proformance this way? or would a one channel 300 watt RMS mono amp give me more power, I mean 300 watts RMS for the amp will be giving the sub 300 watts RMS, and the subs watt handeling is 300 watts RMS, therefor a mono amp 300 watts RMS, would be the ideal thing.With the sterio amp that is 300 watts RMS, the watts are divided between the two channels, thus- I would only get 150 watts RMS from each channel, and i would be only using one channel for the two terminals so i would really only have 150 watts RMS to the sub right?

**hellohello** · 10-11-2005 05:02 PM

um... I think ill back away slowly and let neo handle this, since he seems to know more than i do :D

**Still learning** · 10-11-2005 06:07 PM

ok, what amp would you guys suggest for me to hook up to the sony sub, that would be as close as 300 watts RMS possable put through the sub, because i want to put all the watts i can through it with out killing it. I dont want to have to bridge it, it seems to complicated.:)

**neomagus00** · 10-11-2005 06:43 PM

bridging is actually simpler :p... but the amp we reccommend depends on your budget... do you have any laying around you could use? if so, what are they (model numbers, if possible)?

if you want to do some looking, you want an amp that can do 300W x 1 Channel @ 2 Ohms (assuming your sub is a dual 4-ohm coil model)... that can be a mono amp, or a stereo amp bridged to mono... the stereo option is 150W x 2 Channels @ 4 Ohms, which requires an amp that's twice as powerful, so unless there's a really good deal or you already have one, find one that matches the first spec... if you must choose between over- or under- powering the sub, choose over...

**exalted512** · 10-12-2005 01:58 AM

painted boxes can look much better than carpeted boxes, it just depends on how you do it. Next time, buy a small can of resin and wood filler. Fill in all the screw holes and the seams, put resin on top of that and paint over that after everything is smoothed out.

my next box will be painted. To give you an idea of what it can look like with some time put into it, click here:

thats wrong unless i missed something, which could very well be true because i only scanned through the thread. Especially if your amplifier has a seperate gain for each channel. thats like saying you can hook up 2 amps to each coil and not gain matching would be ok.

heres another picture of that box

**hellohello** · 10-12-2005 07:19 AM

^someone paid atention in art class :) so, cody, are u agreeing with me that the sub's coils should be on the same channel, either 2 bridged or 1 mono?

**exalted512** · 10-12-2005 09:39 AM

i have no clue why anyone would run a 2-channel amp in stereo on a single dvc sub. It can be done if its gain matched, but theres not really a point

**hellohello** · 10-12-2005 09:42 AM

yay! I knew i wasnt completely inept :)

**hellohello** · 10-12-2005 09:45 AM

btw does that box say audiobahn on it? lol

I have a question about the whole reinforcement of sound. If you were to build a box that is long/deep rather than tall and wide, wouldent that have a megaphone effect. If you think about it, when sombody screems down a long hollow tube the sound is magnified, therefor if you were to build a long/deep box it would magnify the bass, yes? or am i sounding like a complete crazy person?

I dont want to spend more than $250 for an amp, if i can buy something good that fits this that would be great; i dont have anythig laying around, its hooked up to my brothers amp now so......
If you have a suggestion for the amp, 300 watt RMS, that would be cool, thanks

so i should over power the sub? how the hell? why would i do that? would i just turn down the bass level on the deck?

I thought about it, but i didnt want to get to expensive for a sony x-plod box after all....

**Still learning** · 10-12-2005 10:47 AM

i am just now realising this... When an amp is-
300w RMS x 1 @4-ohm
300w RMS x 1 @2-ohm

I would choose the 300w x 1 @2-ohm and hook that up to bolth coils because the sony is 4-ohms right?

**hellohello** · 10-12-2005 10:52 AM

I was just curious as to what the box said, wasnt trying to incite rioting...
As for the Long/deep thing, it doesnt amplify the sound, it slows it down so as to emphasize the bass, think of a trombone, when u slide the bar out, u make the tube longer, and the sound gets deeper, not louder.

Now as for the amp, you have to tell us the model of the woofer, i dont mean Sony Xpold, thats the manufacturer and model line, theyre should be a model no. on the magnet of the speaker, if your in doubt, take the speaker out of the box and take a picture of the back of the magnet and post it here :) just make sure it isnt too blurry ;)

I was thinking of this amp but i dont know what the cost is,
