Transmission line loading actually has far more impact on midrange than bass. But traditionally, folks have concentrated on low frequency performance, considering it the sexiest part of loudspeaker design.
The very many posts on amplifier distortion in these threads come across as splitting hairs when compared with loudspeaker distortion. Listen to any ported loudspeaker back to back with a true transmission line, and addition to absence of quality musical reproduction, the amount of hash and trash heard will leave an impact not soon forgotten.
Series crossovers also fall into technology that did not take off, but should have. For whatever reason, folks cannot get their heads around them. Initially, they seem exactly backwards, until you think about how the circuit actually works. The obviously more seamless integration of drivers jumps out as most apparent, as you no longer have a loudspeaker made up of drivers speaking on their own. I find so many loudspeakers poorly integrate midrange drivers and tweeters (classic example: midrange to ribbon tweeter or cone woofer to a horn driver) due to such inherent variation between the two, which parallel crossovers of almost every loudspeaker ignores. Other factors such as the ease of generating slower or faster roll off into first order crossovers to soften or sharpen the sound parallel networks strictly tethered to 6 dB / octave (or whatever their slope) simply cannot also makes a compelling argument
