So I have an HRT MSII and audioengine a5's, and I'm looking to add a subwoofer. The A5's don't have a dedicated sub out, but a 2-RCA line out, so I think they won't be able to detect the lowpass settings from the sub. Since the A5's don't have a highpass filter, I'm wondering if it's possible to get some device which does nothing but split analog signal (coming from my MSII, 2-rca) into two high- and low- passed signals. However, I don't want to lose any sound quality.
Can anybody suggest something, ideally something rather cheap, which can do this? I just don't want to make the A5's run full-range when they're connected to a sub. If somebody thinks it won't really make a difference, though, that would also be good to know.
Note: I'm not using a receiver because the a5's are active, as will be the sub.
Here's a full diagram/listing of the connections I have.
Computer USB to USB HRT MSII DAC
DAC 2-rca to 3.5mm Audioengine A5
Audioengine A5 2-RCA to 1-RCA, 1-RCA to 1-RCA subwoofer.
I can low-pass the subwoofer, but it would also be fine to have the lowpass be controlled separately.
