Re: Future of loudspeakers ?

for mass market reasons, what ever is cheapest will probably rule. However in the tradition of the old HiFi days, where speakers were not built upon the idea of small and cheap, but on reproducing realistic sound, like Klipsch La Scala's.

I feel that high effiency speakers will/are making a good arguement for maybe taking a second look at where we have already been.

Another thing that also has been lacking in speaker design is musical reproduction, aka keeping proper pitch definition (keeping the interval between notes) and Rhythmic Coherence. Too "high end" speaker designers are focusing on technology that alters the sound, usually to the detriment of the music.

When listening to real music, we do not focus on imaging or depth, we listen for the composers musical intent.

I think if manufactuers were to focus a little more on recreating that part of the music rather then soundstage and other "audiophile needs", we might start enjoying listening to our HiFi's more and stop worrying about the "sound" of our equipment.

Alright I will step off the soap box...

I hope everyone is having a great day!

speakers are already fantastic the way they are, why change?

Re: Future of loudspeakers ?

I feel loudspeakers will continue to be very diverse most folks will pick the slim tower types and cubes think these will be arround for a long time yet.But theres a few who are expecting more than just reproduction of test tones and want a loudspeaker that sounds great as well as measures well.Hi eff designs might become more popular as true digital amps become more available I think the quality sounding ones will be low power.As far as transducer tech maybe field coils will make a small come back otherwise we will get gradual improvement of old designs.With energy costs the way there are today maybe the future will be all hieff designs running off digital amps connected directly to voice coil and DSP for drivers and cabinet problems maybe even computer control of field coil and room correction would be the ultimate.I could see these designs being wireless and music coming from a hard drive.But my future will still hold a SET amp and horns

Maybe it gonna be something like this:

Isn't this a bit like the guy who wanted to close the patent office because everything had been invented already?

lol

you could tell your a "hornie"

What do I think will be the future of loudspeakers? Just keep an eye on Bose to see what will be next in loudspeaker design. Aside from the majority of people buying Bose-like speakers...I think we'll see more of the same with possibilities of powered speakers using small digital power amp...complete with digital corrective crossovers inside.

What will come with high quality systems? not sure

enjoy the music!

I'm always hornie these days!

I think the clear nxt speakers are the future.

Re: Future of loudspeakers ?

The immediate future of loudspeakers is digital crossover technology and active operation IMO. Oh and the majority will be made in China.

I think the old trusty "cones and domes" will stay quite some time. I believe that in the future the new light materials, like carbon tubes, polymeres etc, will dominate along with the research of more linear motor systems. I think there is still things to develop and improve.

Re: Future of loudspeakers ?

The trend will be the elimination of the room. The popularity of portable music systems (iPod) will move the market towards headphone reproduction. Us hi-end users will have fancy digital processing to mimic the effect of real speakers using headphones. No room interactions will mean amazing performance for your dollar.

Having researched the barriers to this I've discovered that two things are needed: an accurate transfer formula to translate all the phase shifting, cross talking, and eq-ing that your head normally does, and a way of tracking the wearer's head (since most of how we perceive audible space depends on our head movement). Well, the first part of this is already viable. The second part of it? Cheap digital video cameras and some image processing should handle that. Someone with the knowhow could set up such a viable commercial product today. That and a good set 'o headphones should shame more expenisve speakers.

Re: Future of loudspeakers ?

I think that, as with so many other things around us today, the cost savings associated with mass produced digital technology will drive loudspeakers in that direction. We've taken a few, expensive steps, like this:

Pioneer's Speaker

The ability to digitally manipulate the output to create 1, 2 or as many phantom speakers as you want, and to control the frequency and amplitude response, the ineveitable cost reductions that occur in mature digital technology, and the possibility of flat, on-wall speakers, or speakers built into the front of a video display, computer or, for that matter, virtually any appliance, will drive manufacturers in this direction. IMHO, of course.

Re: Future of loudspeakers ?

Cool topic!

For me, the future will hopefully hold the solution to my most vexing problem - no matter what drivers, the damn things need wire/cables to get signal.

My future speaker will have a digital receiver and amp built in and require no speaker cable to keep it "connected" to the rest of the system.

I'll have to live with some sort of umbilical line for electricity, sure, but that will easier to abide than all my damn tri-wiring and snaking of cables across the room.

Plug and play.

Then, I can tweak the amps or signal converters to taste, maybe even "chip up" certain room/frequency curves that are pleasing to me, and let 'er rip!

As an side: Did you ever notice that in Hi Fi ads, we always see a room set up or products without and cables or wiring being present?

All those clean and sleek spaces with killer goods never show the reality of cable clutter. I think cable runs bother me more than my dang wife!

Someday we may have truly holographic reconstruction of the wavefront (not Bob Carver's use of the word, but true wavefront reconstruction). That will require dense arrays of small microphones in the recording session, and dense arrays of small speakers in playback. The expense would be prohibitive today, but I hope you are correct that a mass market for this kind of fidelity will evolve. Current stereo, 5.1, 7.1, etc. systems are a very crude approximation to what could be done with holographic (Nyquist at the highest frequency) sampling of the two dimensional wavefront.

Re: Future of loudspeakers ?

I agree with the idea that we will see more DSP and amplification built into the spekaer itself, aka, the NHT. I'm guessing wireless will be a big deal as well, although with the above you still need to "plug them in". My big concern is the freenzy to go slim or in wall at the expense of sound quality.

I had an idea about a decade ago, for a thin ribbon tape that sticks on the wall at ear level - it wraps around the whole room, in other words. Then software is used to excite different areas of the ribbon to create a holographic many-channelled signal.

What speakers have you compared these to? There are no NHT dealers in my state (the closest one is in Albuquerque). From the manual I downloaded, I can't even tell how long the speaker cables are.


Reviewed (twice) in Stereophile. The cables are, for me, too long.

Thanks, Kal, my post was well before either of the the reviews were published in Stereophile. I am a subscriber and read your review with great interest. Thanks also for the cable info.
