The sub in was not designed for speaker level input

Sorry, KurianOfBorg! I don't know your equipment or your level of expertise. I'll try again. smile.gif

If you use Receiver "Sub out" to F12 "Sub in" it is safe. If you use the receiver's "Sub out", the receiver manages everything. Do not connect L&R speakers to the F12 when using receiver Sub out. The crossover on the F12 will be bypassed so only F12 sub volume will be active.

On your receiver you will need to go into your Bass Management menu, then select what bass frequency you'd like for crossover. If your L, R & surround speakers are small, try 80db -100db. If larger try 60db. Try several & go by what sounds best to you. Your receiver will manage audio frequencies from there. Your receiver should also have an independent speaker volume level menu to calibrate all speaker levels including the F12 sub but you will need to set the F12 volume to a starting point. Use that to balance volume levels for best surround effects.

If this helps, great, but if not we'll need to know what receiver do you have & go from there.

How is it safe unless the sub is specifically designed to handlle high level amplified input? I know the L/R speaker inputs can handle it, but there is no information on whether the "Sub In" port can handle it. A "Sub In" port is generally only connected to a line level / pre-amp output.

I have an Onkyo HT-R380 which only has a passive (amplified) sub out.

You're right. The receivers sub out is analog, not digital. Note on page 29
of the manual are directions how to turn on or off the sub. Select No. This will keep your front L & R speakers full range. Wire L & R to the F12 first, then run wires to appropriate L & R speakers. Depending on the size of your L & R speakers is where to set the F12 crossover point. I'd recommend a starting point of 80hz. Everything below 80hz will go to the F12, above 80hz to L & R.

I'm not planning to hook it up that way. Since I want to control everything from the receiver, I'll try connecting the Sub Out to just one of the L/R speaker level inputs.

Does anyone know how 1 or even 2 of these would do with an Infinity Alpha 1200s? I've got an Alpha 1200's that I bought new and has hardly been used, sounds great, would just like to have more base for watching movies.

Thanks

Yes. It looks to be similar to the F12. Not sure what you mean by "more bass" though. An F12 will add a little more output but wont go deeper. If youre looking for a real upgrade youd probably be better off to sale the Infinity and get a better sub.

I meant to say deeper base. Thanks for your help.

For a little more money this is a much better sub. If you sell the Infinity it would be less than the F12.

Does anyone know where I can get a F-12 circuit board? Something shorted my circuit board and efforts to restore it have been fruitless.

An ebay link would be great.

mwagiru. You could contact BIC directly to determine whether they sell a replacement amp

Alternatively, you could purchase a replacement plate amp from Parts Express. You may have difficulty getting a plate amp that will fit exactly.

Hey wwinkler! Thanks for replying.
I did contact BIC but did not get a response. I went through parts express and came across this 1x600W TAS5630 Class-D Amplifier Board

It might / might not fit exactly but I think the the specs fit just fine. As I have never done a DIY of this kind before, I need some confirmation whether this is good for the F-12.

Much appreciated!

It isn't all that hard. Most any plate amp will do. If the plate amp is too big just cut out the opening in the sub to the right dimensions. A saber saw is a good tool for the job. If the plate amp is too small, then mount it to a piece of ply wood and glue the plywood to the back of the sub. Here is a shot of my old B&W sub with a new 250 watt plate amp from Parts Express. I only had to enlarge one dimension by 1/8" to fit the amp. I just used a rasp.

This is a long thread! From what I've researched, it looks like the nxg500bas is very close in performance compared to the bic b100 (according to Jim Wilson / jman). And it seems that the bic f12 and h100 are very similar in terms of parts and construction. How similar are they? I'm looking at potentially getting 2 f12's for smoother response throughout the room.

Lol. I dont put a lot of faith into company specs. It seems that actual real word use (and measurements) shows that the more expensive H100 performs no better than the F12.

The PL200 looks like same parts as F12, in different box.

It's the same crappy box, crappier sub with a higher output Amp pushing it hard so it sounds deeper.

I use an F12 for my personal computer audio. It just plays along with music at modest volume levels. If you do the same thing, it will perform very well for you. If you want to use it to play loud LFE in a home theater I would probably get something better. It is a super sub for the price and even a great sub for filling in the bass on speakers that play music. It is comparable to the old B&W you see pictured above. It doesn't perform so well under the stress of loud movie sound tracks. Choose the best the product for the job at hand.

The only difference is B&w products will last about 7 years longer before it blows up.

Ya I've owned F12's one broke down in 3 months had to go through hell to get sent another one. 2nd one died after 1 year.
They are from America, I would have hoped they'd actually build better products than this.
Absolutely hate that company!

Sorry to hear that. I bought one about 4 years ago. Sold it to someone about a year ago for $100 and it still works fine.

They are from China. It doesn't take much to overstress a 100 watt amp with a subwoofer. You played them too loud. You chose the wrong product for the purpose.
