All the speakers I made - suri

[square_wave]

Oh boy ! This sure is a bummer !

I know only one person who is into hi-end diy loudspeakers. From what I have observed, when you work on an original design, it takes a lot of tweaking and pain till you finally arrive at a design which technically works great. Then begins the final tuning to get the speakers sound good to your ears. This takes a while too.

Be patient, you will reach there surely. Best of luck !

Have you ever thought of using different electronics with your design? You are working with very revealing drivers. Hence my question.

Hey Suri

Only the other day I thought I heard the swan song? What happened all of a sudden? Don't lose heart. I'm sure you'll come out with flying colours.

suri,a noob observation here but as cranky mentioned,even i somehow feel it could be more due to the silver havin been used the way it is.remember vaguely some reading on the attributes of silver when used in applications such as this,and the repeated mention of 'brightness'/'sibilance' and so.not to mention,a bad recording as well,probably???

still,give them time,am sure they'll settle down.cheers

Suri, please give the speakers some more time.
What about the WOS? Did their sound change/improve considerably with burn in?
Oh I forgot, the driver is the same right!

hi iaudio -

the 'witches of sound' sounded right at the very beginning and remained so - i cannot remember them improving or becoming worse with the passing of time.

well maybe females find you irresistibly attractive and are energetically trying to get out of the enclosure!

though why not enjoy vishu chill let the speakers burn in for a while and see how it goes things just might even out!

regards

hehehe -

yes i will let these two days pass - and cranky has given direction - which i must attend to - given that doing all the internal wiring again - with copper seems a daunting task - but may have to be done:sad:

What is the brand series capacitor on the tweeters?

The sibilance you describe is a known issue with 100% pure silver wire, as is the honkiness with a high Qts woofer in a very large enclosure with lots of damping material inside. These issues seem common to both you and me, and will not settle for a while, but when they do you will enjoy the results.

In the meantime, you could temporarily remove the damping, and add back a smaller quantity later. I don't know what you've used, but I initially stuffed my boxes with fiberfill but later removed all but a small bit of it - and what was left I teased out the fibers from to make it voluminally much large, to just kill some of the standing waves. It is much better now, though most of the improvement I feel came after the woofer settled down to its final parameters.

I suspect it is an issue of time and nothing more, though you may try this tweak so you can find it a little more bearable.

hi cranky -

ClarityCap.

and i thought i was being clever using silver wire!

will remove the polyfill and see -

hi square_wave -
thanks for the encouragement - felt really bad yesterday!

actually - i never thought of using (better) electronics - are you saying that i should be using class A SS amplification? Using better electronics should have been something i should have, perhaps, thought of - funnily enough, it never occurred to me to do that!

The scanspeaks are very revealing. The person I know works strictly with scanspeaks. He moved from musical fidelity seperates to Plinius top of the line power amp (pure class A) and went from there to design his own SS and tube power amps which are far superior to the Plinius. The scanspeaks scale up to meet the challenges. They are wonderfully revealing with the right amps and source.

Consider an upgrade. Pure class A is not a bad idea. An odyssey extreme amp (same what is being used by SID) is not a bad idea at sane price levels (not pure class A of course). A matching preamp can be expensive unless you go DIY.

 

[sachi]

^^ Agreed...as for a preamp, I would suggest building the Cavalli Audio EHHA-I and use it as a preamp. A formidable headphone amp and preamp.

Other options include Broskie's Akido line.

I am not sure if it is prudent for me to comment on this but Ill take a shot at it.
He has been supporting the DIY community for a long time now. From what I have witnessed in the recent times, he has moved away from supplying DIY kits and has evolved into being a creator of very miniscule number of hi-end gear for serious buyers.
I can send you his contact details if you can PM me with what you are looking for.

sq_w,if i might venture to guess,would 'he' be..siva of corrson???

BEFORE MODIFICATION -

By witchesofsound at 2010-04-15

AFTER MODIFICATION-


Modification involved surrounding the recessed tweeter faceplate with multiple (circle) layers of felt and getting it flush with the baffle-

with this - the sibilance problem has shown amelioration -

the silver wire- i will change to copper

and the cross-over may need change - audio_engr has pm'ed me about that and cranky has given direction about possible capacitor change-

a lot of work!

Suri glad to hear that things are on the way back to its full glory of WOE !!

Well I still say the same that do give some time before you do these serious changes to the design !!

Won't say much as you've already be guided by.......................

sq_w,if i might venture to guess,would 'he' be..siva of corrson???

Yes. That is correct.

 

[square_wave]

Hi Suri,

I am not sure if you are moving in the right direction with this. A Tweeter which is flush mounted on the baffle without any felt will sound good if the rest of the design is correct. I feel you need to leave the tweeter as is and ascertain the actual anomaly.

hi square_wave -

thanks - the felt filling is not too effective - so i will need to start rectification some place else - cables - the first step i guess.

Hi,

If the person Square Wave is refering to is Siva of Corrson,I agree 100%.
I have heard Siva's solid state amp along with the Rs7,00,000/ Plinius and Siva's amp was better.

I wonder if he'd be willing to guide some wannabe DIYers of the forum. Any comments square_wave

@capt.I had already suggested that you listen to the Corrson amp when you go to B'lore,and have given you Siva's contact details.

Hi,

so i will need to start rectification some place else - cables - the first step i guess

Suri please do this before you jump to anymore conclusions and start ripping everything apart :lol: !!

Try one thing at a time and see what results it yields to ascertain the future course of action !! Also give enough time between these changes to fully see and analyze the results of that change !

capt.I had already suggested that you listen to the Corrson amp when you go to B'lore.

Capt should you ever visit Bangalore you are more then welcome to drop in for an Audition of my humble DIY stuff should you be interested offcourse !!
