Heres a tough questions for you hard core diyers?

[johncorn]

Question # 1. ( What is the fastest woofer in the world? What it is made of magnets, voice coil,frame,surround,termails,phase plug,video shielded,weight, So do you know??

Question # 2. ( Same as above for the tweeters.
Planner,silk,text,metal,gold,ribbon,soft,paper
aluminum,titanium,horn,plymer,fabric,bullet piezo,super tweeters,neodyumium,phenolic,mylar,
hybird cone,I think that is most of the top end producers.So do you know this one as well?

Question # 3. How come there is not a speaker that does hi-fi 2 channel music as well as hometheater? A stereo sales guy said that would be the key and would only be one speaker to buy.I starting to think he is right. I have been looking for the perfect speaker system and still can not find it can you?I think human nature keeps makeing me search for more better more more look what I bought.Well that is not me.I just want a speaker that can play everything well
and hometheater. I am looking for that diy kit from heaven. Is it out there maybe only you can help me get closer to the gold pot.So if I find it I will let you know. If you have it plaese let me know. Thanks jm

P.s. I need to stop doing diy projects for a while.I just get my self in trouble.Always doing this project and then that one.So This is my last post for this question.Come on lets see what oyu got.Jm

Only two channels and at 75 watts RMS.
T-Rex, King Kong & the Terminator stomp and shake that room and rattle them curios in the china cabinet to scare the wits out of the miss's and her kids. Kind of sounds just right to me except that rattling in the china cabinet.
If you want more and deeper bass, just substitute them 5'ers with the 7 inchers.
Great for music, at 55 decibels you can still hear & feel the deep bass notes.
But then there's thylantr's setup. A line array from floor to ceiling powered by 3 kilowatts of amperage.

What did your wonderful sales person at Best Buy tell you the difference was? I had no idea that there really was an ideal difference between hi-vi and home theater speakers. Most of the speakers they were trying to convince you to buy weren't perfect either. Not trying to be an a**.

Meaningless question as has been covered repeatedly on this and other forums

Also a meaningless question. There are many many posts arguing out the subjective differences between tweeters. The objective differences between tweeter technologies can be boiled down to two things (since freq resp can be normalized across technologies)
a) dispersion patterns
b) distortion

As far as these two questions go, investigate and take your pick.

There are no end of speaker systems that do well in both realms. If you doubt this, please explain what you think to be the differences in priority between the two applications. The big problem with matching HT with 2-channel is the room, not the speakers - HT wants a relatively dead room compared to stereo, since the 5/6/7 channels excite the reverberrant field moreso than does a stereo setup. However, the desirable characteristics are the same in both cases - smooth FR, smooth PR, low distortion, wide bandwidth.

There is no 'perfect' speaker, since in any real-world system there are always constraints be they on size, cost, aesthetics etc. Looking for a 'erfect' system is futile; instead, you should be looking for one that fits within the constraints you are willing to live with.

That is a killer system. Nice job.It looks so tastey.Does it sound as good as it looks? jm

Well, it was not best buy.Your not a a#@.Is a diyer with his 2 cents worth.I like input.It was a hi-end hi-fi shop.Not some chained store.He was trying to explain something not sell something.jm

Well that is hard to do.The system I like cost $20,000 dollars for the t.v.,speakers,amps,pre amps,cables,power protecter and so on.Yes it does need a dead room for hometheater your right.

It is the ablity if I spelled that right to start and stop on a dime.I mean to stop with the music stops.Not keep moveing for 2 or more sec.after the music stops.Like jet lage.It is called woofer lage.Can a crossover do that or is it the damping factor in the am,p it self?jm

I found the issue with combining a home theater system with a good stereo system using the same speakers is that it is difficult to match the speakers without sacrificing the quality of the main stereo speakers. I feel that a multichannel system should use identical speakers for all channels to preserve the imaging, soundstage and any spatial cues that require perfect phase matching between the speakers (which is more important for DVD-A and SACD). With that said, I use 5 identical 2.5 way speakers in my surround system and sacrifice the quality of the main speakers. There are compromises that can be made like using three way speakers for the left/right and two ways using the same drivers and midrange/tweeter filter as the three ways for the other channels.

It's all a matter of compromising the quality of the main speakers to get matched center channel and surround speakers.

True.That is what I mean.You can not have your cake and eat it too.jm

The radio speakers on the space shuttle!!! Okay, I couldn't resist!

Seriously, woofers are "fast" enough in the frequency range they reproduce (or they wouldn't be reproducing that frequency). Now, Q is another matter, and that may be what you're after. Sealed box woofers, especially low Q designs, have better transient response (how quickly the driver stops moving after reproducing the sound).

As for tweeters, the lighter and stiffer the better. I would say that generally, ribbon designs would be the "fastest" to use your terminology. But there are many traditional dome designs (metal and cloth) that sound just beautiful.

As for Home Theater/2-channel audio, the same rules apply to both. You want good frequency extension, SPL, and smoothness to name the most basic attributes. If there are differences, it is as one poster said, you might be trading off two high quality stereo speakers for 5 identical, but lesser quality speakers for the same cost. Therefore, I would say that you can have just as good a home theater speaker setup as two channel, but it will cost you 5/2 (two and a half) times as much, not to mention a good subwoofer which can serve both music and Home theater equally well.

Cheers,
LeoF

> Question # 1. I have no idea. I can tell you that your amp can make a heck of a difference here. THis is one of the reasons my Pioneer VSX 810 is collecting dust.

> Question # 3. How come there is not a

Cool I love it.Thanks for the info it helped.So what kind os speakers are on the space shuttle?A very good question?

[johncorn]

True and over priced as well.I do not like them at all.jm

All wooders have the same 'speed' if they don't its called linear distortion. This is when voice coil does not move in proportion to the signal. Some woofers sound 'faster' but this is more likely a function of damping and Q.

The problem is that for any claim of topology superiority someone will point a design or commericial product that uses something different that gets good reviews or has a large following. It also depends on the application.
A 10" 2-way with a ribbon, bad choice.

This takes a compromise see:
<A HREF="http://www.wilsonaudio.com/products/alex/index.html">http://www.wilsonaudio.com/products/alex/index.html</A>
This might be a reasonable compromise between HT and music, but for the ultimate compromise, that would be the company that rimes with nose.

That was to easy to guess.I say bose.right.A lot of comapanys are going from floor standing to bookshelf.I guess to save on production cost.jm

I just don't like using their name, it makes it easy for them to search for comments on their products.

I myself don't care if they see what I write.

EVERY bose system I have ever heard has been a load of crap !!!!

[thylantyr]

>you?

I haven't found a store bought speaker I like
and for sake of argument, lets say I did,
I wouldn't want to pay $500k for it even if I
was rich.

I find satisfaction by doing experimentation
with 'off the shelf' drivers and I find the ones
that will perform well for a particular design.

If you want your dream speaker system you
will have to do some work, either by auditioning
store bought or DIY.

The first thing you need to do is to define
what you like in a sound system then try to
solve the mystery one step at a time.
