Replacement/Upgrade horn on the KTM LC4 Adv

Oi!

I am going to ask Santa for a horn for christmas and curious about choices and what not. I know there are a few but these were the ones I focused upon.



They do offer the single horn which would be easier than trying to fit a double (it is a one horn bike I believe).

The big question is... wattage; specifically 72 of em. Is this not a problem for a short burst thing? Are the stockers similar?

Hella Twin Supertone Horn
Compact horn with outstanding sound. Rugged black body with red protective grille. Comes with bracket for screw-mounting. Kit includes horns, relay, mounting bracket, and installation instructions.

Voltage
12V

Frequency
300Hz low tone
500Hz high tone

Sound level
118 dB

Connection
Flat plug

Power consumption
Max 72W


Dimensions
4-27/32" dia. x 3-11/32" depth

dont panic about wattage unless you ride around with them on all the time. you've got enough juice to honk those badboys for a couple good 30 second blasts per ride

If you were behind me and pushed the button on those things... after I got back up, I'd shoot you repeatedly.

They are loud as hell.

Hell no! get 2, or even 3 of the things. Great for waking up overworked soccer moms drifting into your personal space.

Say it loud... yer' Meat and yer' proud!

I'm Meat!

Now off to hunt for wiring upgrade and fuse info... two upgrade horns will likely fry the stock wiring or just trip the fuse when I reset the pacemakers on those oblivious seniors in their Buick Landyachts.

I thought I saw something by bentspoke regarding wiring upgrades with more power requirements on the HID thread.

Na... you just use a relay to step down the amp draw to the switch. Easy as pie... should come in a horn kit.

Ah, see that in the kit. Excellent...

And a lil tidbit for the kiddies out there who didn't know (like me):

"Stock horns typically have an output of 97 dB. The decibel scale is logarithmic and therefore the sound pressure doubles for every increase of 3 points, i.e. a horn with 118 dB is approximately seven times as loud as a stock horn."

Me so HORNY!

I briefly had a 139Db Striebel Air horn on my bike (adventures work shop). Great horn but, it was way too bulky and the only space I could find to mount it was back on the luggage rack so I'd wake myself up with each horn blast. Unfortunately, being exposed on the luggage rack, it gobbled up a whole lotta sand when I did my infamous Power-endo ground loop and has not been the same since. Now it emits a pitiful 2Db (yes two!) Db whispering whirring noise when activated and now sits in the "its no good" bin . I was contemplating Fiamms until I saw your post.

Hmmmm, 3dB ~ double the air pressure so 97dB stock to 118dB for the Hellas is 7 times louder... therefore, 139dB Striebel is 14 times louder than stock.

HOLY BLEEDING EARS BATMAN!!!



Um, the Fiamms might be groovy, the Hellas have a name I know - there is also another one... Check out this site: the wife apparently is musical and gives a critique of the horn:

The Supertones:

Note that the ones from India are "dissonant" so in this case you get what you pay for!

I mounted a set of Fiamm horns (130db), one on each side of the headlight assembly. Just tapped into the old horn wires and presto instant ear bleeding, dual horns. I love seeing illresponsible drivers knee jerk the wheel back into their lane causing them to almost oversteer and spin out of control. No more nappy time for them.. I purchased the dual horns from JC Whitney in Dec02 for $30.00. No problems noted so far.

Think that site's physics is awry as found several references to figures that support the following table. A 20db increase would only increase perceived loudness by 4 times. :





































dB Change Voltage Power Loudness
3 1.4X 2X 1.23X
6 2.0 4.0 1.52
10 3.16 10 2
20 10 100 4
40 100 10,000 16

thanks overlandr,

that's right, the log scale should never be linear! so it is less difference at low dB changes and ALOT of difference at high ones. therefore, the hellas are only 4x louder than stock (still purdy loud as heck) and the Striebels are actually over 16x louder than stock.
