speakers and cables

this is about me being a loser and problem creator.

I finally got a 2nd subwoofer and I was excited to hook it up. Well, not too excited. I knew it would be a pain to hook it up. I was excited to hear it. I spent over 90 minutes connecting the speaker wires to my power amp. When I turned it on, the left channel was gone. It blew the fuse. I disconnected everything, replaced the fuse, hooked it up again. It worked for 10 seconds, blew the fuse again.

The way I hooked them up was I went from the sub speaker out from both subwoofers, rolled the left and right side wires together so I had 4 wires that I connected to the left and right plus and minus channels - speaker binders on the power amp. What are my options? My preamp has no sub out. Nor my amp.

Stupid question: should I just go from left to left on one sub and right to right on the other sub?

I don’t mind adding a low pass filter and reconnecting my subs.

A high pass filter would actually simplify your subwoofer connection. Speakers would be. You’d need one extra pair of RCA interconnects to go from your preamp into your high pass and then RCAs from low pass to amp. Since you were able to try ’Y’ connectors out of your preamp, I assume you already have enough RCA to reach your subs. But remember, and not to start controversy, the quality of (RCA) interconnect cable (particularly to & from the low pass filter, imo) will make a difference.

I am interested in this low cost low pass solution, as it should fix the overlap.

Not only should this clean up a bit at where your subs and mains overlap, now your amp will be freed up not to be driving the low frequencies from your main speakers. There are pros and cons, but overall I think you may really like a HP filter in your system.

@mswale

to clarify, the link what you sent is a low pass filter. What I need for my mains is a high pass filter?

Assuming you’re a 2 channel guy, get a Wiim Pro Plus streamer (200 dollars) or Wiim pro (150 dollars) streamer...Word on the street is that it’s newer firmware lets you do cleaner bass management (digital domain) and many other good things.

@grislybutter: I won’t try to speak for @mswale, but a HIGH PASS filter is what I thought he meant, and I certainly screwed up (OOPS!) when I posted above by referring to a HP filter a a LP filter. I edited my post.

You already have an adjustable low pass filter on your subwoofer. The high pass filter is what would edit the frequency of the signal going to your mains.

(So if the high pass filter was set at 80hZ your mains would then only theoretically only try to go down to 80, and then you could start playing with the low pass on your subs from 80 on up, and trying to match the subs with the mains.)

@immathewj

almost there. Very dumb question (you are used it to by now) does the high pass filter go between amp and main speakers? Or between preamp and amp?

(and I know sub HAS a low pass filter so I just have to connect it to the signal BEFORE low pass filter.)
