Hi erniejade,

Nice to see you.

This is a really interesting question. The short answer is yes. The longer answer follows.

There are lots of ways to connect things but I think that I would run the source (DJ mixer?) to the F1 Subwoofer and take the line out from there to the input on the L1® Classic. You can have some fun trying the L1® with or without a B1. Using the B1 will change the crossover point on the L1® (for others reading along this only applies to a Classic or Model I). You'll want to try it both ways.

I have tried the F1 Subwoofer with the Model II and I've found the sound to be overly bassy (but you can turn that up or down on the back of the F1 Subwoofer). The crossover is different on a Model II, and it might sound better with the Classic/Model I. You can read about my experiments with the F1 Subwoofer with the Model II. Skim over the first two posts and then we get into the discussion that should interest you.

Does that help?

Correct me if I am wrong but the L1 MII plays down to 200, sub or no sub connected? (B1 or B2)

The F1 has a freq range of 250-40, but is internally crossed at 100 no matter what setting the F1 is on.

One thing I found when comparing the B2 to the F1 (which I pretty much knew anyhow) is that the B2 has a lot bass (spike between (90-110). Lots of stuff happening here that is overly hyped, and does not sound all that great on modern music, although probably great for live music. I dialed most of that out on the Parametric EQ, but the F1 does not have the quality, and that is a good thing in my book.

The F1 regardless of spec sheet plays so much lower that when comparing the two subs, it almost seems something is wrong with the B2. It is missing that entire octave.
I think the L1 Classic or original hits 120 hz without a b1 attached. Sometimes it can get a lite screatchy when pushed without it. I was hopping there wpuld be a way to hook one up and kind of have it think it had a b1 attached with a bit more kick to it. I think with a b1, it crosses itself at 180 hz.
Hi erniejade,

Good memory.

Actually it's 110 Hz.

If you connect anything to the Classic/Model I Bass Line Out, the crossover moves up to 180 Hz, and the output of the Bass Line Out is a bandpass (no EQ) 40-180 Hz. So you could try connecting your source to the Classic, and connect the Classic Bass Line Out to the F1.

I thought about this yesterday but my gut feel is that it will sound overly bassy. I have a Classic here and I'll make some time over the next few days to do some tests.

Yes.

Here's what it says on page 11 in the F1 Flexible Array Loudspeaker System Owners Guide.



"HPF passes input through a high-pass (100 Hz) filter. Affects LINE OUTPUT signals only."

I just did a quick test with a spectrum analyzer. The output of the F1 Subwoofer is unaffected by the setting of the Line Out EQ switch. This lines up with the documentation above.
