Hi the reason could be trivial A speaker sounds boxy when the box make noise Then what can make a speaker box make noise ? the woofer of course your speakers are 24kg/each The towers that disappear are 100kg and more high stiffness and high weight are what to look for Like in the...

Hi ! disclaimer i am ignorant But why not using a small resistor to tame the tweeter Wilson Audio do this to fine tune the response in room of their speakers https://parts.wilsonaudio.com/parts/bundled-resistors/

Hi very interesting mod The response above 2kHz looks much smoother some designers use felt around the tweeters to get a similar result i guess

Hi ! thank you very much for your great work and congratulations for your impressive collection why did you choose 80dB level ? will the curves change at 90db ? the FRs seem all within +/-5dB I would say that all should sound good ? any differences in sound should be related to something...

i use one of this it was showed to me from a representative of speakers manufacturer Fischer & Fischer a resonant cabinet will amplify the sound of the carillon very much Needless to say that tried on the above mentioned brand speakers the amplification effect was practically not...

Hi very likely imho i guess a lot indeed. The Thiel 3.7 have been designed to provide better performance at an higher price point i am sure they must have built many prototypes using different materials for the baffle and decided for machined aluminum (as per Stereophile review of the 3.7)...

Hi thanks ! yes i see now Wonder which one is right 0.34 for Qts is fine as i said i would be curious to see the results of a multitones test the less the intermodulation products the better of course Lately i have become so much more interested in speakers And the main reason...

Hi thank you very much for your interesting post i am not sure to understand how the distortion test has been carried out As i said above i have been quite shocked by the bad results the woofer is quite big and was used also in the epic dq10...

very interesting posts Thank you very much i am a little on DIY what stops me to cannibalize some cheap units with potential is that almost all used smd parts Off limits for me for instance i am using one of this from Neotech it sounds quite clean The biggest weak point is the volume...

the only large cab will be for the woofer that could work also as stand I do not like wide baffles The needed volume could be obtained with more depth but again the woofer cabinet will make or break the sound It is a challenge Many good speakers have so so cabinets proned to resonate The...

hi really great project indeed Nice this is my reference model for look Of course the parts can vary a 3 ways with the woofer in a separate cabinet The beasts must be kept in cages Seriously the control of woofer vibrations is for me by far the biggest challenge I do no like the...

Hi there are rare applications but usually expensive and complicated I remember the Jeff Rowland Synergy that has the option of a battery power supply Or Dartzeel Or Sutherland some models But as you say a very minimal noise levels can be reached with proper filtering Batteries are less...

https://www.hifiengine.com/manual_library/jbl/l166.shtml midrange starting from 1kHz Yes but i am afraid i could not stand breakups Actually i am looking at nice little fullrange from Faital Pro 3 and 4" units almost all have a strong peak at around 10kHz This worries me for using full...

Hi thank you very much This is an extreme of course I saw in a JBL monitor i think i agree the midrange performance is key for great sound but the question is which are the lower and upper limits of the midrange ? when you have answered this question you can start look for a suitable...

Hi thank you very much and sorry for the belated reply but i did not receive the notification Yes after the FR i look for CSD IMD and THD mainly As you say usually these measurements are carried out only by third parties Usually for any other industrial product the specifications are enough...
