Speakers: Anything really new under the sun?


After a 20-year hiatus (kids, braces, college, a couple of new roofs, etc.) I'm slowly getting back into hi-fi.  My question: is there really anything significantly new in speakers design/development/materials? I'm a bit surprised that the majority of what I see continues to be some variation of a 2- or 3-way design -- many using off-the-shelf drivers -- in a box (usually MDF at it core) with a crossover consisting of a handful of very common, relatively inexpensive components. I'm asking in all sincerity so please don't bash me. I'm not trying to provoke or prove anything, I'm just genuinely curious. What, if anything, has really changed? Would love to hear from some speaker companies/builders here. Also, before one of you kindly tells me I shouldn't worry about new technologies or processes and just go listen for myself -- I get it -- I'll always let my ear be my guide. However, after 20 years, I'm hoping there's been some progress I may be missing. Also, I unfortunately live in a hifi-challenged part of the country -- the closest decent hifi dealer is nearly 3 hours away -- so I can't just run out and listen to a bunch of new speakers. Would appreciate your insights.

I recall seeing a video on YouTube (sorry I don't have the link) that showed a cone flexing and going out of shape as it moved in and out, so the selection of cone material by the manufacture is really important.

Absorption material in the enclosure can be useful in not allowing internal reflections to impact the movement of the cone. From that point of view a vented enclosure might be helpful as long as the horrid sound emanating port is addressed.  

I agree that resonances can never be fully eliminated but they can be lowed so they have negatable impact.

Here's what I use:

Well worth investigating along with a sound deadening covering of all internal surfaces to help with lower frequencies.

This takes some effort, but it worked wonders for me. I'd love to hear if others can achieve a similar result.

Grab a suitable grounding cable and connect it to the frames of all speaker drivers. You'll be amazed at the improvement. Manufacturers spray the frames as bare metal just isn't acceptable, so you'll have to expose the bare metal at the attachment point so the earth works.

Cabinet resonances are an entirely different matter which can be reduced with better internal lining of all surfaces and filling the enclosure with sound absorbing material.
