Agree with Beetle. Unless you are listening to strong wide band AM then stereo speakers of even the smaller bookshelf type are not what you want to enhance your ability to pull something out of the mud. You want narrow band audio 300-3000 Hz at the widest and preferably narrower. When DXing on the AM broadcast band I usually tuned my receiver in SSB mode listening for the tell-tale heterodyne of an AM carrier between the regular North American channel assignments every 10 KHz. I did this because the receiver bandwidth is much narrower in SSB mode than in AM mode and it also made it easier to detect a carrier. Once I had detected a carrier I would select either USB or LSB whichever gave the best S/N ratio. From there i would narrow the bandwidth as much as possible in order to filter out as much noise and interference as possible. For weak signals you do not want wideband audio.

BTW using this technique I was able to detect many 1 Kw AM broadcast stations in Central America that were positioned between the regular 10 KHz channels. Also some 10 Kw AM broadcast stations in Europe most notably from Norway on 1314 KHz and even Chah Bahar Iran on 765 KHz........but it was running 1.2 Mega watts at the time.
