I can't follow the argument at all. If making a cap change makes the differences in the amps very evident, how can you then say the amps all sound essentially the same?
Speakers as the principle component/other components are servants
Speakers hold the Kingship in our overall audio systems.
I think my recent posts have substaniated this thesis, well at least my opinion of sorts.
This OP came to me after reading through some of (most of what is too deep for my understanding)
pedro's
topic
**Why is science a starting point, yet not the end point?*
Meaning science gives us all sorts of parimeters, specs, graphs and such. Most of which we have no clue how to interpret,
All we ae concerned is , **how does the speaker actually sound**.
Pedro suggests science has let us down, that science, if it was so intelligent, why can't science tell us which speaker is the superior and which the inferior sound???
Obvioulsy science is not the end all /be all.
Its only a tool, human sensibilities come in at the very end to say
Yea
or worse
Nay
I say nay
to all/eversy xover design in the fq's ,,ohh say 800hz = 15khz.
Yeah I know thats a massive chuck of our music.
As many of you know i make very long winded posts
But actually I reduce them to make them more readable and so folks don't lose interest.
~~~So cut to the chase.
We accept high tech in every aspect of our lives.
You name it, super high tech is there,. Had you told us back in 1965, folks would be walking around with telephones, sending pics/videos,,we'd all laugh you at your face as scifi fantasy.
~~~Long story short.
The new wide band /high sensitivity speaker technology. What gives?
Why the denial it exists?
Why the fear to inquisite?
Why the lack of interest?
Why the rejection?
Speakers will crown your system with beauty Or else render it as distortion/low fidelity.
Tweak/,od/upgrade all you want, at how much you care to spend $$$$$ ($40K!!!) on cables etc.
Ain;'t going to make hardly even a miniscle gain in sonics, if the speakers are ~~faulty~~ due to low sensitivity.
Bass woofers, I'll grant low sens Seas and Scaspeaks high end woofers a stunning succcess.
Above 800hz, I have issues with any driver neededing a xover.
I tag these fq's with xovers. The Wet Blanket sound. Sounds mechanical, like compressed music,, comming from a box.
Squeezed, contorted, tiny soundstage, strained fq's if vol is over 10 oclock. = fatigue/Coloration in abundance.
Many fq's of the source, missing in action.
I am not suggesting these new wide band is for everyones taste. Not at all. Only that we should at least give these wide band a consideration as a possible alternative to our old traditional ideas.
Inqusisitiveness is a good thing in all things audio.
Without a healthy curiousity, we putrefy , stagnate.
Even Worse
we might miss out on the super high fidelty we all hope to hear one day in our systems by this neglect of the new high technology in speaker design. .

larryi2,540 posts07-06-2021 1:43pmI can't follow the argument at all. If making a cap change makes the differences in the amps very evident, how can you then say the amps all sound essentially the same? I found the Mundorf SESGO .47's on the 12 tube circuit to be substantial gains in the slam bass department. Worth the $650?? Yeah I;'d say so, 1 time deal. , maybe even some gaisn in upper mids.highs, Not sure as THE SEAS MILLENNIUM IS A MISERABLE 87DB SENS = dysfunctional, not able to register the gains made by the addition of the .47 SESGO Mundorf caps. The W18's responded nicely. This is what i am trying to get it, I am confident if we take the Jadis Defy7, and swap the caps with the highs ens speaker, We will all note both bass gains as in the W18's response, but as well note gains in other fq register 'Why? Sens is much higher , like 91++db, On the Vox spec page. TRUE 91db, Seas Millennium has dips valleys, and is nota solid 87, there is SIGNIFICANT roll off over 10k hz. And thats with Mudorf high end caps in the xover. = complete waste of money. The Mundorf's only gave a MINISCLE tweak upgrade to the Millennium resolution. Point being higher sens, wide band, will trump any dome, in fact any tweeter Ribbons, AMT's you name it, every single time. Wide band are simply magical, and most folks just find them mysterious and **what i can't understand, is not worth looking into* And back they go to xover brands. . No xover fan-atic can give any supportive reasons why we should all stay with their popular vote. All factors for voicing high fidelity point in the direction of wide band. Its here, and ain't going no where. What is moving down hill are xover speaker sales. Ck out the used grave yard. WOW, 45 days, no bites. Its sad. Really depressing to know other audiophles are suffering with their listing. I feel for ya. |
I suppose you need to define “low sensitivity”. If you define that as speakers in the 87-92 db range
~~~~~~~~~~~~~~~~~ In general wide band = higher sens, = 92db++, Low sens xover types = 91db lower. Very hard to finda xover type at above 90db, Most are 87db, like my Seas Thors. tahts too low to make magical high fidelity, Those folks are only fooling themselves. Their speakers are not fidelity, Its distortion. Been there done that. |
Low E speakers is below 85%, that is still HiFi. 86-93% is HiFi high E speakers. It's as simple as that. Above 93% you are IN PRO territory. 98% and above is pure PA. From a speaker manufactures point of view it was ONLY a dollar and NOISE issue. Highly efficient speakers will show EVERY flaw in a noisy system and good pro speakers have GREAT Voice Coils. They stay cooler and hold TURE to their spec sheet. The issue is cost.. the VC normally for pro is at least 8 ohms and measured at 1 meter. NOT the hype of HiFi and 4 ohm BS. Today because of very quiet preamps and power amps, "SOME" of the manufactures are using Pro and PA speakers mixed with HiFi speakers. LOL all is good UNTIL you get a noisy valve or you go deaf and can't hear the noisy noise floor. 87-92% is a VERY efficient speaker and with care NOT to noisy. BUT above that. Mercy. I can here the HISS in Antioch, CA from El Paso, TX, make that Atlanta GA..:-) It's a loud one.. The old Klipsch at 99 to 103%. With a noisy system my ears just wouldn't let me stick around.. Same way at concerts.. CRAP sound, or noisy equipment.. I was GONE.. BUT that same speaker (Klipsch La Scala or Corner horns) with a super quiet Mac or Marantz or HK citation. LOOK OUT!! HEAVEN... OP what the heck does, "Low sens xover types = 91db lower". MEAN? Below 85% is still HiFi. I've heard BIG electro stats that were in the 60% efficiency range that would blow your friggin' mind... Just had to DRAIN a local transformer at the POLE to get them to sound really really good.. 500.00 PG&E bills behind A/B 600 watt mono block amps.. Rich Kids!! Not me.. They just didn't sound they way they could with class ds an 2000 watts.. What a Pitty! |
Very interesting, the pro drivers I have seen are garbage relatively speaking. A great dome tweeter is a work of art ferrofluid and all. Have you seen the casting of a Dayton subwoofer basket? 1st class. Lower efficiency is not an evil if you can afford the watts. If anything it is the sign of a highly evolved crossover. If you are hung up on pea shooter tube amps then you have a big problem. I have yet to hear an uncolored full range driver other than an ESL and even they need a bit of tuning. I you think you are going to get decent bass out of an 8" driver with a whizzer cone stuck on it I want some of the stuff you are smoking. Midrange is worthless if there is no bass and treble stuck to it. I've got news for you, science gave us all the wonderful drivers and components we have and science is perfectly capable of given us insane sounding loudspeakers it just gets expensive. Science has no control over the room you stick them in. However science again comes to the rescue with digital signal processing and the in home test equipment to get any speaker working at it's best. |
