With a sound tone that is similar to the Fiamm Freeway Blasters, the Stebel Magnum horns have slightly less volume but also offer an authoritative tone.
We purchased the Stebel Magnum horns in England and the retailer had them listed at a rating of 139 dB, a figure that we now know is so off the mark that it’s laughable.
The Stebel Magnum horns have a slightly higher pitch than the Fiamm Freeway Blasters; the high/low pair have claimed 500 Hz and 410 Hz frequencies, compared to the Freeway Blaster horns at 485 Hz and 405 Hz.
The factory claims 115 dB, but we measured only 81.9 dB at 2 feet away, a variance of -33.1 dB.
The Stebel Magnum horns somehow feel lighter than the Freeway Blasters, even though they’re not; it may be that their shape makes them seem lighter.
The silver plastic cover on the back of the Magnum horns was unattached on one horn and loose on the other when we purchased them, and the horns overall seemed like they are built to lower quality standards than the Fiamm horns.
But they still sound pretty good, with a car-like tone. Mounting should pose about the same level of complexity as the Freeway Blaster horns.
Not much else to say about these, they would probably work fine if nothing else was available, but they just didn’t make a big impression on us.
Roughly comparable to the Fiamm Freeway Blaster horns, the Stebel Magnum horns were slightly disappointing in our sound measurements, registering a measly 83 dB at 20 feet. Even the stock Ducati horns were louder than these.
UPDATE: The Stebel Magnum horns were installed on the Suzuki V-Strom 1000 ABS (Blog) with good results. See the Stebel Magnum Horn Review Redux.
