Right now, I have in my possession the Emotive mini-x a-100, which I already have an RMA number for because I was planning on sending it back.
The reason I was planning on sending it back is because of my subwoofer setup. The only place in my room that the subwoofer sounds good in is the far back corner, and I have a home made RCA cable running around the edge of the room and around the door and under the bed to get to the subwoofer.
I currently have my studio monitors and subwoofer hooked up to an onkyo HT-R540 receiver, and am using the software in the receiver to send the bass to only the sub via LFE and the rest to the speakers. The crossover is at 60hz.
I was wondering if it would be advisable to get a higher quality sound card with rca output, put that into the emotiva amp, split the speaker output on the emotiva amp, and use the rca to carry line level to the sub. I could get a female RCA plug for each end of the LFE cable, which I would solder two wires to and leave them bare at the other end for plugging into high level outputs on the emotiva amp, and high level inputs on the sub.
The downsides to this would be that i would not have a high pass filter on the speakers, only a low pass filter on the sub, and also that the RCA cable consists of a center conductor with a thick shield around it, grounded on both ends. I am not sure how high level would sound going through a wire like this. would the negative lead being the shield and the positive lead being the center make them interact electromagnetically?
what do you guys think? The main problem in my opinion is the high pass filter on the studio monitors. I do not want to introduce distortion to the mids by making the speakers play the bass notes which they are not rated to produce below 40hz or something like that.
