Hey guys, I have a single eclipse 12" sub and it is running of a eclipse two channel amp. I have the sub in a sealed box with a volume of 1.78cu. ft. Its that big because that the biggest i could get it with the MDF availble at the time of construction. The manual says 1.93cu. ft. but i couldn't get it that big. I listen to trance and house and find that with the box facing the rear of the boot it has trouble keeping up with the music. I have it facing the rear as you all know you get more volume out of the sub. However when i face it to the front of the car, it doesn't have any trouble anymore and can pump all day and never slow down on a quick beat, however i do lose about 2/3 the volume.

Now i hear people say that 10"s are better for music with faster beats. Even if my sub is facing the front they say 10''s are more responsive. Is it true? I have never heard a 10" really other than those at the shop and i like 12"s because.....well its either a 12" or its not a proper sub, but i think that is just me.

Opinions?

Cheers

I've found exactly the same thing recently, turning my sub and installing it firing into the car. I lost some volume (a fair bit) but I think it sounds just as clear - keeping in mind it's not complete yet.

From what most people say, 10's are tighter and I think they do return quicker - but that's ONLY comparing the exact model of sub. If you compare a high excursion 10 and say a sony 12, the sony may be tighter due to the rubber and voice coil etc.

Maybe you should try Two DVC 10's off the same amp? It's just a suggestion.

lol ive never EVER aimed a sub towards the back of the boot, its always against the seats...


would u prefer a loud system that sounds s**t or a quieter system that sounds better?


a 12" is fine for techno stuff if facing forwards.

i dont know how the volume is better when the sub is facing the other way... in my mums car i canot notic the volume difference but the quality facotr is 2x better facing the seats.


if the sub is not as punchy as u want try looking at getting a higher wattage sub. also go to a store and ask about really punchy subs and compare them with the 10" drivers.

i find that altho 10" is nice and punhcy, it doesnt quite make enough bass for the bassier techno songs i listen to.

also the 10" doesnt seem as loud at the same volumes as a 12" or 15"'


thats my 2c i dont know if theres any scientiffic proof or anythign behind what i said but it comes from expereince.

well with the sub facing the back the hole car shakes and i feel hands on the wheel vibrate. Facing it towards the cabin means hardly any vibration but i do hear more sound even though i cant feel it.

Well the physics of it say that a 10" (all other things being equal) must be faster, and quieter. So my solution - 2x 10"s lots of bass, and tight response - forward facing.

Yes well i always have believed that 10' subs were the best for the techno and dance etc... As they will provide a better response and sound that is suited to that genre. A 12' sub is great for Hard rock and metal thou, really brings out the best sound. I love my Alpine sub atm it sounds bloody awesome even thou its underpowered.

But yeah definately go 10's if your gonna listen to the techno and dance music! :)

It's my opinoin that when the sub is facing the rear of the car it uses the volume and shape of the boot to reflect and amplify the sound. Its like having a box in a box! When it's facing the seats you lose the effect and instead you hear only what the sub would produce as though it were in an empty room (well, behind a chair in an empty room)

I personally do not notice much difference in quality between having them facing either way, if anything it sounds flatter when having the sub facing fordwards, but thats more than likely due to the boot amplifying certain frequencies better than others. I dont notice any timing issues at all either way. But the increase in volume more than outweighs the benefits of a slightly cleaner sound ;) all you need to do is fine tune the EQ a bit and your laughing anyway

When you do fire the subs into the cabin, then it is best to completely seal the cabin from the boot area. So basically if you've made a box that fires fowards, then try to seal up any gaps around the box so that you cannot see into the boot. I have personally never actually done this, but have heard mentioned countless times...

I had a 15" but found that it just wasn't suited to my music (hard NRG, trance a bit of metal etc), so i've p****d that off and am now in the market for a nice pair of 10's. Will have the same surface area, but will be much punchier :D

You could try building a smaller enclosure for your 12" to make it tighter.

Is your amp big enough to run the sub?

If you are having to point it rearward to hear it the it's under powered. Rear facing does increase db but decreases SQ. I always set up subs to point forwards as the custoners want good sound more than 'BOOM'.
If you prefer the rearward facing BOOM then get a time alignment corrector.

yeah my Hu is a 9831 and has time correction. The amp i 150wrms and the sub is 170wrms. So its pretty matched. I faced it to the front and like it better because it has more sound. When it was to the back i found that the boom and air vibration would kill the sound. I like it better now that its at the front.

LTDHO you sound like you know what your talking about. In the future i will be buying some type R subs. You probably think i am talking s**t but i am going to be buying four of them. I listen to house and trance so do you think if they are powered right and face the front 12"s would be just as good for response as 10"s.

cheers

rockford fosgate power amp. umm 2000wrms at 1 ohm. the type r's are 500wrms each so i thought they would have enough power at 500wrms each.

I had a look and am tossing up getting shipped from the USA cos its cheaper.
