BIC PL-200 as mid-bass modules?

As I wrap up my UM18-22's build I've been kicking around what to do with my PL-200's. I was considering using them for mid-bass but after checking them out on data-bass I'm not sure it's a good fit - I wanted to get some feedback from those here using a four-sub setup with mid-bass. I imagine most here know the Dayton's so here are the BIC's.


I'm hoping you can help me with a couple things as a starting point:
1. Is mid-bass truly between 50-100 or are these just 'comfortable' numbers to gravitate toward?
2. Do the BIC's fit the bill or should I look at alternate solutions (bearing in mind it took some selling with the wife to do the Dayton build)?
3. Where would you align crossovers to get started?

I've picked up the UMIK so hopefully I can start to get my arms around it in the next few weeks; I'd appreciate any thoughts to get me headed down the right path.

Cheers!

I threw mine in the trash after limping it along with an nu1000dsp after the amp died. If yours are still working you might try them nearfield but as your measurement shows, they aren't very good <35Hz or >70Hz.

Oof - shame about the amps. Both of mine are fully functional and, honestly, not bad for what they are. I was considering using the UM18's for anything sub 50hz and EQ'ing the BIC's to handle the 50-100hz range; from there the LCR would take over on the top end. I also considered having them both cover the midbass range for some added umph, with the UM18's taking over for the low end.

In my experience the PL-200 weakens as you get past ~70 - 80Hz, and they can't handle enough power/EQ to do what you're after. This was with a single PL-200 and not the newer version II.

Of course, YMMV, every room is different. If you aren't concerned with their outcome give it a try (might do so at lower volume).

The PL-200s are a great subwoofer..... for somebody else.

Sell them and use the funds to buy happiness. Those little guys served you well but we're...

I tried to use my old F12 for mid-bass. I used the line level inputs to feed into it, with the outputs going to the mains, and tried various crossovers in Audyssey.. I couldn't get it to integrate properly, so I took it out of the chain, and crossed my mains higher to let my 18s reach into the mid-bass region..

Hmm... So far not sounding like a winning combination. I've got dual sub outs so I was planning to run a splitter on one for the BIC's and the other feeding into the NX6000D; I'm running on the assumption that my Denon can manage a separate eq for each sub out then I'd further tweak the 18's through DSP. First and foremost it sounds like I'll need to run REW for the 12's to see what my in-room looks like before going too far down the rabbit hole.

I will say this: couldn't hurt to give it a try. Tinkering is half the fun.

Not sure what your receiver is, but I don't think many receivers have separate controls for the two sub outs, they are usually identical. To get the best out of this setup, you'd probably what a MiniDSP.

Depends on which model Denon. That would require SubEQ HT, which as far as I know, is only available with Audyssey XT32.

I'm running with an X3500H which does have Audyssey XT32. In looking at the manual for Graphic EQ it does show the option to adjust tone by Each under speaker selection - it doesn't go on to call out subs so it could go either way.

If you have that app that allows you to adjust EQ I would think it'd give you the answer.

If you look a the Max Burst for the PL-200 on DB, it's right there with the lowest ever measured above 60hz. So honestly it would be a terrible MBM, and your UM18s would put out fair bit more midbass then these(10db+). If you want MBM's I'd just sell the PL-200's and use it to fund a Maximus 12's, PA460's, or something of that nature.

That's what it looks like. However, I'm a bit confused - isn't CEA2010 only measured from 20-63hz? If that's the case, are any points above 63hz valid?

It is, but Ricci tests with additional points at 10, 12.5, 16, 80, 100 and 120hz, on top of the 20, 25, 31.5, 40, 50 and 63hz ones used in the standard CEA2010 test.

Love my little PL-200. It's still kicking for like 8 years+

It is designed as a cheap and pretty little 12". It has a humped up frequency curve on purpose, designed around the undersized amp, weak 12, and the port and small box size.

It does o.k. from 35 to 70hz. Gets really boomy above 80 because of the compromises. I still use mine for my morning radio listening in my living room. Works well for radio playback with butt-rock.

It does decent without being stressed from 35 to 60, but above 80 or below 35 it is not good.

Mid-bass is from 80 to 150+ and you want overkill from 80 to 150 and likely without pushing spl mid-bass is hard to achieve anyway - chest kick wise.
