BIC America F12 sub anyone ? - Page 93

post #2761 of 2834
Had to move into a new place(cabin house a real one) and i have this bic F12 slightly behind me and have it on digital at 80hz on my cheap pioneer with everything else on small and it sounds so GOOD. i can not even tell where the sub was maybe my floor at my old place and so on was making this sub overly noticeable? I'm 100% happy that i bought this sub now and thanks to this thread for helping me decide this over the Polk 505.


Heck the only thing i noticed is i don't think this sub is 100% shielded not that it matters much but still the actual driver is not shielded.

Placement is everything. Shielding was important to prevent accidental magnetic tape erasures and magnetizing CRT tvs. Not such a big deal anymore.

Anyone can compare Dayton sub-1200 and BIC f12? Any significant differences? Thanks

For starters, the Dayton has less power and a smaller frequency range.

A friend based in Asia just relayed a power source issue.

I have used the receiver for a few days with a 110V convertor but now decided to use the recommended method to convert it to 220V operation. I followed the BIC America F12 official instructions to change the voltage input from 110v to 220v by changing the jumpers after opening the control plate. Unfortunately after this is done, every metallic point on the back panel including all the switches (On/Off, Phase selector) etc are conducting electricity so that when you touch it gives off an electric shock. This has been checked with a tester.
Tried the power directly though the wall socket as well as through a voltage regulator which gave a fixed voltage of 220V, but with the same result. If the connections are changed back for 110V operation, it does not conduct any electricity on the back panel.
Fred from BIC America said this is the first they have heard of such an issue. In the meanwhile as I wait for BIC America to respond wanted to know if anyone has had a similar issue?

I just ordered this sub from Amazon and I'm matching it with Mirage Nanosats. A bit nervouse about it playing all the way up to 120hz. That's where I'll be crossing it over

It'll work fine up to 200Hz. 120Hz should be no problem for the F12.

Yeah. I'm more concerned with how the sub will sound handling the mid range.

I found the Bic F12 to play it's best between 30Hz and about 150Hz. This is where the bass was pretty tight and powerfull.

The sub is capable on it's own. Just a matter of how it plays in your room now.

That's good to know ...it'll be placed at the front of a room next to a wall on one side only and on tile floors

Put it on a piece of carpet or some kind of rug.

picked up a 2nd f12. should be here friday.

anyone have any thoughts or recommendations on having two subs far as placement goes? how do you sub crawl with two subs? I have never had two Home theater subs before.

I am in process of building my home theater. 1st coat of black paint on so far. Hopefully only 1 more to go! Got a denon x3000, sony hw50es, chief mount, 134" carada screen, and 2nd bic f12 that should be here friday.... and hopefully not a divorce!

Apologies, but I couldn't find the thread portion where you discussed the PA PSW505. I have that sub, and I wonder why you chose the Bic over this one? This is my first sub, and I truly love this one, especially for music. Since I found a great deal for a pair of KEF dual-8"driver mini-towers, I've wondered how much better they might sound with a different sub. Anyway, I have been looking at the BIC lineup and they seem to be equal to the Polk Audios in almost every way. Of course that has almost nothing to do with how they actually sound, and having no other sub to compare I can only go by what owners of other brands describe.

Thanks for any help on your choice.

EDIT: I wanted to add that when I first hooked this Polk Audio sub up, I used a pair of Bose 301s as mains, all connected to a cheapo Sony 7.1ch receiver I'm using as my PC sound system. Anyway, the PA sub easily overpowered those Bose 301s, while the KEFs have the opposite effect, as they tamed the sub quite handily, and the mid-bass has improved 1000%.

update - My F12 arrived today, as I mentioned before it's paired up with 5 Mirage Nanosats. I'm crossing the sub @ 120hz and I think the combo sounds really good. I still have to play around with some channel volume settings, but overall I can't think of a better bargain for a 12 inch sub that sounds this good

Click here to see how to perform the subwoofer crawl.

I have two F-12's in the rear of my HT, about a foot away from the side walls.
Also, I have two SVS PB12-NSD subs in the front of my HT, also about a foot away from the side walls.
After running Audyssey MultEQ XT32, with Sub EQ HT, all four subs sound and "feel" great together.
post #2778 of 2834
thanks, i know how to sub crawl, just didn't know how people were doing it with two.
post #2779 of 2834
It's the same as with one. Just pick the best two spots you find during the single-sub crawl. My son picked the number one and number three spot because of his furniture layout, and it worked out fine.
post #2780 of 2834
I was able to get my f12 to sound a bit tighter by tightening the screws where the driver is. They were not loose but not tight either, so by doing that I'm getting less resonance from the enclosure.

I've had it for about three weeks now and now that it's broken in, I've had to lower the volume a couple of notches.
post #2781 of 2834
just placed my order for this sub still confused on how to break it in and adjust it though I am going to use it with two monitor 55t's L&R monitor Center and monitor 40 series rears paired to a denon 1613 can anyone give me tips on what hz I should set it to and how to adjust it??
post #2782 of 2834
Start off with the crossover on the back of the sub set to it's highest point, set the volume knob on the sub to about 10 o'clock, then in your receiver, set crossover to 80 Hz, and see how that sounds. I have mine set that way with small Jamo bookshelf speakers, and it sounds pretty good to me. You can always tweak it to your liking if those settings aren't good for you.
post #2783 of 2834
So why do I set crossover on sub to highest point if my speakers are all set to 80?? I a just trying to learn as I am fairly new to higher end home audio and not your standard htib or sb..
post #2784 of 2834
You do that so the receiver controls the crossover.
post #2785 of 2834
so Once I do that should I just let my Denon run the multeq test?

Yes. Set the sub xover all the way up so that the receiver can control it and set the sub volume at 10 o'clock. Run Audyssey and the 1613 will set all the speaker volumes including sub volume accordingly.
post #2787 of 2834
Awesome thanks guy's for the quick responses... Love this forum..
post #2788 of 2834
And don't be surprised when you run Audyssey if you need to dial the gain on your Bic down to a setting of "2" or even slightly lower to reach an acceptable level. I think that's fairly typical. Enjoy your new sub!

I wouldnt even be able to hear mine at 2. I have it set about 6.
post #2790 of 2834
Mine is set at the 9 o'clock position
