Do clothes make the man?

The following is an extract from a post discovered:

"  I recommend seeing if you can find a set GE 12DW7 and calling it a day. NOS supplies do seem to be drying up recently so getting a few spares is not a bad idea. In my very limited 12DW7 tube rolling experience, the GEs are slightly brighter than the JJs and Raytheon I have tried...the difference is barely discernible."

@abnerjack  Wow, those are nice speakers. I'm not sure which specific model you have, but both are claimed to extend down to 25 Hz (-3 dB) and have a sensitivity of about 89 dB.

From what I've read, the 5-inch midrange driver covers an unusually wide frequency range—from about 150 Hz all the way up to around 5 kHz—because there is no electrical crossover between the midrange and tweeter (most speakers cross over between roughly 2.2 and 3 kHz). As a result, the midrange driver is likely to beam at higher frequencies, meaning its off-axis output is weaker than its on-axis output.

With that in mind, how does the soundstage from the upper module perform when driven by a low-powered tube amplifier?

At a 150 Hz crossover point, I think the REL subwoofer should integrate well with the system. However, I'd also be tempted to bi-amp the woofer section and see how much the overall system scales up, as well as how it compares with using the REL.  My theory has always been that the speaker's original woofer integrates better with the rest of the system than an external subwoofer, particularly in terms of pace, timing, and texture.

@pindac   Thanks for finding that tube.  This seems like a foolproof solution doesn't it.  I'm shopping for them now.  Any specific seller you like?

@lanx0003 This is the Verity Parsifal.  Again, it doesn't have a true woofer, only the midrange.  The specs show it to be, if I remember correctly, 91 efficient.  If the larger woofers are  out of the picture, I think it would probably be around 94-95.  I havent noticed anything negative about them.  I listen at moderately low level and near field, so I don't ask a lot of them.  I think it is a match made in heaven.  It would be hard to bi amp as I would have to tear in to it, and I don't have the desire to do so.  Thanks for the feedback.  BTW, I really like the Rep's because you can adjust them when necessary.  As you know, bass is all over the place, depending on source, so I find this an elegant solution.  It is fun too!  Sorta tailoring your own sound, like you can do with your clothes.  I love puns.

After more deep diving, I think the Mullard is the ultimate, with the GE being a better bang for the buck and the RCA a good option.  Maybe I need all three.  As Sir Walter Scott so famously said "Oh what a vicious loop we weave, when chasing what we can't achieve."  No wait, that was Google AI.
