I just looked up some info on my HF horns and I seen they are rated at 110dB from 2.5kHZ-20kHZ. now the LF drivers I have are rated at at 97 dB from 35HZ-2.5kHZ with a highest reccomended X-over at 800HZ that would leave me a bit soft in the middle range from 800HZ-2.5kHZ. I am using a 3rd order X-over that has -3dB at 800 HZ and drops 18dB for each octave. (It is a PL-800 can made for the Peavey amps 1 for each channel as I am running in stereo CS-800 LF and CS-400 HF) What I am debating is I found some 3" mids I could use and run them off the HF amp along with the Horns with possible a cap on the horns to allow them to function in their proper range and the 3" to fill in the middle area. Any comments on my Idea?

WOW, a fellow audiophile!
I/We need more info on what you are running, when, where, how, and most intriguingly - why? I'm not sure of your setup, and clueless as to your gols.
For now - I wouldn't worry too much with low impedance, as speakers can cover past their parameters both ways. Just make sure you stay within impedance!!!! That 3" you're thinking about adding could mean certain destruction to your rig. For guitar/bass, 4 ohm woofer (and horn for bass/keys/pa) combo would cover most of what the band needs...venue and size of your couterparts' "artillery" would determine wattage and need for a soundman. And then the mikes, explosives, motorcycles,...
For home theatre and car audio, PM me. I am still saying WOW at live performance...takes me 1.5-2 hours to figure out what the soundman was "trying for" usually. Less-bleeding ears?
EDIT: I didn't see the other post and I'm a little more confused with more info...

More responses, please, before I have to jump in here............. All right, I'll bite ... but I'm warning you ... ... I know very little about such things, as all I've ever used is combo amps - no cabs, which have but one speaker ... so no worries about whether to go in series or parallel. That said, if you add this 3" speaker you are talking about in parallel, I am worried that the resulting ohmage will result in ownage. On the other hand, I believe that running the speakers in series is a safe bet as far as the load on the amp goes, but I think that the resulting increase in effective ohms of the two speakers in series would subsequently reduce the volume of that part of your setup, so you may lose the ability to fill in that you were looking for. That's as far as I can go with my guessing. Any good? D2o Edit: P.S. if this is something like one frequency cancelling out another or timing of transition or something, that's way out of my zone. Have a look at this document to see if their discussion of some of the issues helps at all. Further edit: I began to do a little bit of research about your setup last night, and found two things: 1) whatever "bridging" is, I read of a potential problem depending on the speakers used (I saw it in reference to 15" speakers though) ... I don't know if bridging equates to the parallel issue I was mentioning above ; 2) more importantly, when I said I know very little, I may have overstated my qualifications.
