hey,
living in darwin we don't really get n e goss on brands other than
sony rockford alpine pioneer kenwood etc
but does n e one know much about these venom subs i've seen on the net
they go hard?? :badgrin:
i'm looking at really making my wagon heard..
being a big free air space i wana maybe put a 15 in there aswell as my 12
and i was wondering what these venom subs were and if they are worth
getting??

I have a 12" venom...they go HARD as man!!

HEAPS of mechanical movement..

actually there's a guy on caraudioaustralia.com that sed he ran upwards of 400wrms thru these puppies and didnt have a problem.

y do people think about puttin 15s and 12s together?

they r 2 different sizes...which will create a different moving pattern between them...hense giving out different sounds...not a good thing

thats y most good car audio places will insist you dont use 6x9s with subs!!!

Having different size speakers is good. I haven't really seen people with 15's and 12's in one boot, but 6x9's and 12's or 15's yer for sure. The 6x9's will provide midbass and the subs can do the lower frequencies.

As long as the crossovers and gains are set right (tuned) It would sound better than say having 4x 6" speakers and a 12" sub.

beta running say 6" 3ways or sumfin alike....
to a trained ear u will hear different frequencys with 2 diff sized subs...

the best sub combo would be to have 2x10's and a 15!!

6x9"s arent required with this setup but it is the best sounding combination i have ever heard - and i have heard quite a few!! but i am not gonna bother with 15's in the magna!! maybe just a single or double 12 will be fine enough!!

As for the 2 size subs - it is good because it gives different frequencies - the 15's are good for really really low frequency bass and the 10's have the respo0nsiveness for crisp clear thumps!!

Manual

Yeah I dont like the idea of 2 different sized subs..

Also depending on what music you listen to will dictate the size you need.


If you listen to stuff with really fast kick drum (eg: Fear Factory, Dream Theater etc) A 15" has less chance (not saying it can't..just bear with me) of coping than a 12" simply because a 12" is smaller and it takes less time/energy to move forward and back. So it is easier for it to keep up.

Simple physics :)

15" are generally good for rnb, rab, hip hop, dance...stuff where the bass isn't as quick as prog rock, metal etc

But as you go higher in your price/quality range you'll prolly find 15"s that can keep up with metal for sure...Im not saying that they all cant... :)

i'd heard about cars with 12" and 2 10" covers all bass requirements leaving you with the cripsy yet rumbling effect for those low frequencies.
i was just thinking cause of the wagon and a large surface area that a 15 and whateva else would be a good combination..not a 12 n a 15 but yeah maybe a 15 n 2x10's???
so i dunno,, i guess i'll look into it.
so the venoms run pretty good hey!!!!
my mates got 2x12" type S alpine in his wagon running off a V12
and u can hear him from a fair distance away
i guess i'm really looking for something different..
a lil usual to catch the eye...
15" and 2x10" with a real good setup...neons and stuff!!!!

i refuse to let you use to different sized subs!

You seem keen on a 15". Save the $ from the 2 10s and extra amp and get a super good 15 and a mad amp to give it the go!

I can gaurentee you wouldnt hear ne difference then!

Youll also have change for a nice sub enclousre!

i run 6x9's on the back shelf with my 10" in the boot and there is no problems there, it sounds better with them in than it does with the 6x9's out.

You need a range of speaker sizes to get all different frequencies!

OK, so with say u got a 10" and a 15" subs.

Ull certainly get different frequencys....But imagine hearing once bass beat from ya 10, then ya 15...its gonna sound weird! very weird...to different sounds...different times...

*** that...id stick with a good 15"

thats like saying having 6" speakers at the front and 6x9's at the back is bad, but infact it sounds a lot better than 6" all round.

It won't sound wierd, if you look at pro speakers they have all different size speakers, like 5.25", 8", 12" etc...

with that set-up the 6x9s should be puttin out bass...front maily highs n mids.

try puttin bass with a 6"...have fun listenin :)

i have that current set-up (6 1/2" front n 6x9 rear) mainly bass from the rear, and it is good.

but with bass you dont want two different notes...you want one strong one!

ok, if you don't believe us, go to your local night club and look at the speakers, I bet they don't have all the same size speakers.

go look in your car...i bet it has very different acoustics and settings then your magna does

:)

I hope I can help out a bit here. I'm halfway through a degree in Audio Engineering, so I've spent 18 months tuning my ears to different frequenices and waveforms. If there's feedback at 1.2kHz I have to know that it's 1.2kHz, that's the kind of tuning I'm talking about.
Firstly, different speaker sizes. The only real problem that may occur is comb filtering due to the increased inertia (resistance to move) of the larger driver. Comb filtering is a phase problem that occurs when a signal is slightly out of phase (not in sync) with itself. This happens all the time in a car due to the many reflective surfaces (ie. windows etc.). A larger speaker driver (eg. 15" sub) will have greater mass and surface area which will not allow the driver to move back and forth as efficiently (or as quickly) as a smaller driver (eg. 10" sub). Therefore a smaller driver will be able to handle transients (fast attacking sounds, eg. kick or snare drum) better than a larger driver. However, the physical size of a speaker cone will generally have an effect on the frequency response and will definitely determine the resonance of the driver (consider resonance as the driver's most favourite frequency to reproduce because it can do it so well, it is the frequency that the driver and it's mechanical components are 'tuned' to). Also, the greater the surface area of the driver's cone, the more air it can displace. That's the speaker size tradeoff.
Now, putting two different speaker sizes together. Good speakers that are correctly mounted on-axis, regardless of size, should not conflict with each other. Two different sized speakers will not produce different notes. However, they will most certainly have different frequency ranges, ie. a larger sub may handle anywhere down to around 12Hz (8Hz below human hearing) while a smaller sub may only go down to 40Hz (1Hz below the lowest string on a 4-string bass guitar). This will be the difference you will hear and you will only notice it if you are in the same enclosure as the speakers, which is the case here, and you have been training your ears for much longer than I have. If a frequency that is prominent in both of the drivers' ranges is played then their output will reinforce, in fact it should double (simple acoustic theory). You will only notice a drop in signal level if the frequency goes below or above the frequency range of either of the drivers. What happens here is only one driver is producing those frequencies efficiently.
Now, mounting. If you are ever mounting speakers of different sizes and frequency ranges, whether it be subs in a car or a hi-fi speaker box, the driver's should be mounted on-axis. This does not always mean they can be mounted flush on the surface of the box. It means that the voice coils of each driver must line up vertically. Basically try to line up the magnets on the back of the driver. This will effectively eliminate time delays and thus comb filtering. In the recording studio we use co-axial Tannoy loudspeakers (a co-axial speaker is a driver which has both the High Frequency driver and the Low Frequency driver built into the one cone structure, completely eliminating delays and directional problems) as our main monitors. Having said that we also use Yamaha NS-10s as reference monitors and they are not mounted on-axis. Needless to say the Tannoys sound clearer and there are no phase or directional issues.
I am also a bass player (I play a 5-string bass which goes down to around 30Hz). Bass amp speaker setups come in a number of combinations but the most common box would be a 4x10" box. This provides the player with the punch and drive needed for rock and funk playing. Some players will add a 1x15" box to this to get a more dubby bass sound with lower frequency emphasis. In fact you may also see a bass player with a 4x12" or 2x12" box stacked on top of a 1x15" or even 1x18" box and it will sound fine.
Personally, I would go for the combination of a 10" sub and 15" sub just because you will increase your frequency range not to mention the increased transient response of a 10" sub. With that setup you will have a punchy bass sound that will also shake your bones. There's no real problem having a 12" and a 15" together as I've explained but there is no real advantage in it either.
Hope this helps.

EXCELLENT response! :)
