DROP IN TEST DD vs. Fi

[chris the man 49]

thats right fellas tomorrow night my build will be completely ready to TL a drop in test with Fi and DD

specs are as follows

car electrical

220amp mechman alt

3 optima batts

few runs of 0 ga

big 3 (ofcourse)

car box

2.7cubes tuned to 60hz with 76^2 port

port and sub firing into the cabin

car amp

Sundown 3500

Car Subwoofers

Fi BTL UFO D1

DD 9515H D2

to make the test as fair as possible, voltage and charge times will be alotted between each run

BTL will be run at .5 OHM in same box

9515 will be run at 1ohm in same box

not going for a single style, like outlaw or anything.

just the highest score we can get for each.

i really hope the btls wins this shit, because its honestly louder to my ear than my dd.

VIDEO RESULTS WILL BE TAKEN TOMORROW NIGHT

Is it really a fair comparison? Considering they will be ran at different impendances?

Clamped power should be roughly the same if you're doing a test like this.

Is it really a fair comparison? Considering they will be ran at different impendances?

many may say the DD has the advantage because the g and H motor hold more records than almost any sub.

many may also say the BTL has a better peak.

i feel it is fair to run them head to head this way.

worse case scenario i could always back off the gain a tad on the Fi but i feel i dont need to

[rodneydude23 5]

Yeah I getcha. Wish you had a few more subs to compare! That make things more interesting..

lol we have a SMD but its too dam long for the box LOL

you can always send me your 15s

i cant gaurntee youll get them back tho

LOL JK JK

we tested a HCCA 15 3 days ago

BTL on a straight drop in beat it by .8 dbs

THATS HUGE

[ssh 924]

Tuned in. Wanna see this btl rape

[chris the man 49]

Tuned in. Wanna see this btl rape

me too, i just love my ufos power

Lol I'm not sure how much my 15" icon would like all that powah

[bcst86 5]

that btl is sexy

[QuinnyGT 4]

Be an interesting test, Why not have them with matching impedences?? As small a dfference in power will be, its still going to affect the scores IMO, will you be clamping them??

[kraz3one 0]

Watching this.. can't way to see that btl do dmv tho I love my old dds

[Duran 387]

Even if they are at the same nominal impedance, the impedance will peak differently with some power on them.

[edouble101 314]

Tuned in....

[poundindak69 15]

warching this

Waiting !

[chris the man 49]

You guys are all definayely right. The btl does technically have an advantage. My friend lost my clamp setup. So unless we buy get it ready then no . I'm just tired beyond tired of DD as a sponsor right now. Everytime they tell me something new I have to have DURAN clear it up.

So I'd rather give the btl any advantage it can get.

Regardles all settings will be kept the same on the amp we may calculate the gain and back it off a tad bit on the btls run.

How the hell are you gonna do that? if you don't have clamp meters? ..

So this test is already worhtless before you begin it..

If the DD wins this one i'll take off my hat for this one.

My friend will have his clamp meters

We are just doing a basic test man. It's not going to be in all professional

That's exactly it. If the all mighty DD wins when it has the power disadvantage we will know who is king.

No..it is not a definitive answer, there is no definitive answer. It is not black and white like that..the only thing that can be said is speaker X was louder then speaker Y in this very specific install. It does not remain constant at all what so ever .

Some speakers work better in some applications..for reasons that simply is a waste of time to find out.

I DO agree!,

in this install we used the specs that you sent my teammate Tommy, 2.7 cubes we just bumped up the tuning a few hertz

this is a basic fart box install i feel it can actually prove quite a bit about each woofer. surely most people have room for a 3cubic foot box.

its a great general test and as far as i am concerned has only been done 2 times useing the exact woofers, only in 18"s tho.

DD gave us 2.5cubes tuned to 65hz

but we decided to go with what you emailed my friend as it seemed like a much better idea.

[shizzzon 461]

Ok, let me say something.

Ok i'm done..

Nah, ok here it is-

My buddy had a DD9500 sub, do not know what revision the motor was and a BTL ufo motor.

Both were 18s.

Did a direct sub swap.

Box- 4.5cuft NET, single 8" flare port tuned to 42hz.

Powered by 2 SA Saz3ks @2ohm strapped.

DC Power 270A alt and 3 Batcap2000s.

On a burp- BOTH subs did exactly the same score- 152.7db

However, the differences were great when the power was lowered.

On lower power, the BTL put out a considerable higher sustained output than the DD did.

also, the BTL was more musical or should i say more enjoyable to listen to on music than the 9500 was.

So his conclusion was-

BTL won hands down.

Sounded better on music, more smooth.

Was more efficient on less power.

Able to produce same score as DD sub without the extra money it cost to own one.

Obviously, the DD may not like this box but that's all the test offered.

[rodneydude23 5]

So then btl ftw?

i can definately understand those results

i figured that would happe to us
