By "match closely", do you mean physical appearance or impedance? Speaker characteristics for SSB and CW may differ. The best overall compromise I've found over the past 45 years is the Heathkit HS-1661. It is very efficient, as in LOUD, has a thick aluminum cabinet with no vibration or peaky resonance. Radio Shack sells a replacement speaker that fits perfectly if needed. For CW only, the MFJ ClearTone, MFJ-281 is hard to beat. It peaks strongly at 700 Hz and is very sensitive. Cost about $12. The HS-1661 shows up on Ebay occasionally and usually sells for about $30 or so. I painted mine black. Modern stereo speakers will work but they usually have higher power ratings and require more power. Amplified speakers will also work well but could be affected by RFI depending on brand and model.
