Hello, I have a Swart Amps Space Tone, ST-6V6se amp, which is like a customized Tweed Princeton/Champ 5F2/5F1 circuit. I like this amp quite a bit, but I think I am about fed up with the extremely dark and dull sounding Eminence 820H speaker that I have in there at the moment. I got this speaker like 3 years ago, based on many good reviews about his hemp cone speaker. I mean is not a bad speaker, but for some reason in this amp, it sounds quite dark, middy and kind of dull, with very little high frequency definition. I have tried all kinds of different tubes and I just get a small improvement. I was thinking maybe it is time to try a more chimney speaker, with better clarity, articulation and definition, with emphasis on the high frequencies, something that could bring something closer to sparkle. I know that the Tweed amps are not the best in sparkle highs, but I think this amp could do better in that area. I the amp does have a Tone knob to make it brighter and I also have a good eq pedal, but still is not able to bring what is missing on this amp. The Eminence 820H was good in being better in the low end frequencies for an 8 inch speaker and sounding bigger with it's good efficiency of 96.1 dB, but I think I am ready to trade in this for a more chimney, brighter more open sounding speaker and I think that the reissue alnico Jensen P8R could probably get me there. I would really appreciate some thoughts on this new Jensen P8R reissue speaker!!! Cheers!
