TOPIC.
After four and half year turbulent travel down trial and error lane. Now near destination, i.e full sonic satisfaction goal, despite flaw in panel.
INTRODUCTION.
I would like to inform interested members how I have recently realized Martin Logan hybrid ELS 9 full potential with Anthem amplifier after substantial passage of time, namely about four and a half years. This improvement was piecemeal. First, credit goes to my colleague Roberto. Second, to ELS 9 instruction manual author since inside was valuable placement advice. Third, some credit to me for not being completely satisfied with acoustics. Tinkered with cables, software setting and room placement. Kept tinkering until all jigsaw puzzle pieces for achieving superb sound fell into place.
FIRST STEP.
First step is to determine expense budget. And then undertake research to acquire a music system that fits inside budget, has potential to create sonic satisfaction and possess synergy. I did the research but in the end decided to implement Roberto’s pinpoint hardware recommendation to me. He is expert in this area and has clear insight into audiophile electronic equipment and their synergistic combination. My hardware acquisition each took place separately over time.
Roberto recommend:
Martin Logan ELS 9 hybrid speaker.
Anthem STR integrated amplifier.
Nordost Blue Heaven 2m speaker cable for panel.
DH Labs T-14 2m speaker cable for woofer.
Audirvana computer software annual subscription.
My decision:
Shunyata Research Venom USB cable.
HP Pavilion desktop.
SECOND STEP.
Matching cable, electronics and loudspeaker in addition to optimized room fit, room placement and room dimension is key to unlock full sonic potential of system.
First, in my opinion large ML hybrid not unleash complete sonic potential in small room. Therefore in a small to small-medium room that are unsuitable to electrostatic hybrid speakers try Daniel Hertz music system. Price approx. 13k.
Second, perfect placement allows minimization of deleterious effect of standing waves in room. This will be achieved if formula given in instruction manual is followed. Formula is for ideal room. Since most rooms not designed to achieve optimum acoustics. The further your room differs from dedicated optimized room the greater measurement gap between manual trial and error adjusted placement and location obtained from formula.
Third, take care not to place music system in oddly shaped room with low multiple unsymmetrical sloping ceiling. If possible keep in rectangular room with one level ceiling. Length of room greater than width. Position loudspeakers along length of room and according to formula given in ML instruction manual.
CONCLUSION.
Three aspects to ELS 9 loudspeaker design I feel if ML implement without increase in retail price may lead to substantial improvement in sound, increase in MLO member and other owner satisfaction and therefore increase in revenue earned by ML.
One. ELS 9 panel width narrow. Increase panel width. Perhaps maximum to Expression 13A size. Additional cost to ML not much. Why not increase panel width if there is substantial improvement in sonics. And small increase in additional expense. Will help to acquire greater market share in this ultra competitive segment of market.
Two. Design rear woofer to be of acoustic suspension type. Therefore match in design with front woofer. Additional cost to ML not much.
Three. Ensure ELS 9 profile of change in impedance with frequency similar to ESL X. I assume if comparatively amplifier friendly profile can be achieved for ELS X then why not for ELS 9. This will make ELS 9 compatible to a greater variety of amplifiers. Cause delay in high frequency roll off when increasing volume in tube power amps with less robust power supply.
The magic of electrostatic panel is in high frequency transient speed, image size, imaging, air, purity, sonic picture and sound stage. When wired to Anthem amplifier, ELS 9 and if recording excellent give a taste of above sonic qualities. Curvilinear line source due to expansive panel and no crossover create spacious sound stage and larger sonic picture.
