Louis' drivers have their compromises, most apparently in the midbass. The 7" driver that Dennis played with likely had a falling response below 300hz. Its top end is also less extended than the RS5 driver.

I would argue that if we are swapping tubes and capacitors, contouring the response at line level by adding a resistor or two is not that different.

I agree with your last sentence. But we are talking about very little $ and maybe use of caps I already have to play with a minor DIY project. This is a hobby afterall!
