Hi all I’m in spain, I bought a custom fit sealed subwoofer for my smart roadster. Its the isotec smart roadster subwoofer.
If you search in google, you can see, that’s a really tiny car and every cm and kg is gold.
Its driven by an 8” peerless 110W RMS 4ohm subwoofer. I bought an 2x 70W RMS amp, bridged to 140 output.
My first need from the sub, is a very deep bass, and that sub, fails totally. The LPF is set to 50hz, at 30-40% volume, its sounds quiet good, but then, distorsion kicks in quiet soon. The sound gets very punchy and dry as soon as distorsion kicks in.
I can set the LPF to 128hz, and the output gets more powerful, but I dont really like the sound, very dry punchy and cheap, doesn’t even sound like a subwoofer, sounds more like my grandpa’s 80’ 2 way loudspeakers.
So I bought Sundown’s X8 sub 4ohm version a few days ago. Did not come yet, and I fear it won’t fit in the enclosure but that’s not the point.
I wonder if I will get a better output. I searched for the X8, because I’m fed up of low excursion, and simply searched for one of the best excursions out there for that price.
Now the tricky part. I can’t change enclosure, its a 10l minus the space taken from the driver. I don’t think its portable, no space, and the whole box is uneven, because it has to fit into the car.
X8 is not sealed friendly, does it mean I’ll have a bad output?
My idea was, to fit that thing, drive it with my 140 watt amp set at 50hz and hope for no distorsion.
I mean, the actual sub, is loud enough, the problem is the quality it total **** because of distorsion.
I know its retarded to drive 750Watt sub with 140Watts amp but atm I don’t need more. Maybe I’ll upgrade in the future, but the whole car is limited, battery is 12V-40A
Another question is, will the amp explode while driving that sub at 75% of power?
I was looking for diverse subs, including some Kicker, SA8, sealed friendly subs etc... but the X8 has such a great excursion, I have very much space for upgrade in the future.
Thanks!
PS: If the amp is set to 50hz, why does it still sounds punchy?? I'm a newby in this, LPF what does it really mean?? Does it means, it peaks at a certain frequency, like if its set to 100hz does it mean it peaks at 100hz, or does it mean it cuts everything from 100hz on???
