Bi-Amping speakers with only one input?

swegyptian

Hi there,

I have a set of 3-way speakers that I really like, but they only have a single pair of inputs. I was curious if I could still biamp them by modifying the crossover, and changing the speaker terminals. Could it be as simple as disconnecting the leads that feed the mid/tweeter, and connecting them to an additional set of terminals?

Any help would be great.

Thanks,
Alex

Yes,as long as it does not have a series crossover(they are rare) then you can just add an other set of terminals.Ofcoarse assuming you can correctly determine which crossover components are for each section.Be aware that each amp driving the different sections will need to have the same gain or you will have an imbalance between the mid/tweet and woofers.

I currently have a Denon POA5200, and was planning on picking up another when one pops up for sale. Can I just use splitters on the RCA out from my reciever? Or does that mess with anything? I guess I also need to see if I can split the auto on cable to turn both amplifiers on too. I know that a stereo 1/8" cable does not work, and I need to use a mono cable, but I wonder if a stereo 1/8" splitter would work. I guess I will find out later.

Thanks GV#27.

EDIT. I just checked the back of the 5200, and has remote in and out, so no problems there.

Sure you can just use a RCA Y connector on the pre outs.

Since you don't have a second amp gathering dust, I would suggest going for better interconnect/speaker lead synergy.
The costs of second amp/speaker wires/interconnects/and associated connecters could add up to a better primary set of connections.
Maybe better in cabinet connections and upgraded wire could take your system to the next level. Just food for thought.

I was thinking that I could upgrade the inner speaker wiring while I was at it, but honestly I'm not a really big fan of pricey cables in general. I really only go for nice heavy gauge speaker cables.

what kind of speakers are these that you want to bi-amp. also, what are you driving them with now. im asking because i was wondering if it was worth the time to make it all work. if you are using a receiver now you can go to a more powerful amp. that would make the speaker sound better.

I have a Pioneer Elite VSX54Tx for a preamp, and a Denon POA5200 on the front speakers. To biamp I will probably find another one, or buy two new matching amps. Maybe the speakercraft BB2125. These are my speakers:

I would buy some Polk Speakers with twin binding posts. The LSi line is awesome.
