Is it possible to know preference ratings among the harman brand loudspeakers in controlled double-blind tests so it would be easier to choose where we set our own point of diminishing returns based on our different budgets.
I would have to convince our marketing department to release this information. In addition, we would have to include a specification that captures the maximum SPL output capability for each product so you know whether or not the loudspeaker meets your application requirements.
At the present time, I am trying to convince marketing to publish the comprehensive anechoic loudspeaker measurements that I've shown you, and which CEA and CEDIA are considering to adopt. JBL Pro already publishes these measurements for their products.
From these measurements, you could pretty well tell when you've hit the point of diminishing returns in terms of sound quality -- max SPL capability notwithstanding. I have a mathematical model that will predict the loudspeaker preference rating based on those measurements with 86% accuracy. For example, if you compare
speaker curves P and I, they hit very similar performance targets in terms of on-axis, listening window, early reflections, sound power response, hence the preference ratings are within 0.5 rating.
Additionally, I have a question regarding the jbl lsr 4300 series. I have searched the net and looked at the manual. I cant seem to find how to integrate another sub with them using its room mode correction software. Wouldnt the room mode correction of the mains not work optimally if I use other subs (for example an adire audio and svs sub) and they couldnt be controlled by the software? Or is it imperative to also purchase two lsr4312sp for the system to work optimally?
I believe the
JBL LSR 4300 series room correction wasn't specifically designed to take advantage of multiple subs canceling room modes via acoustical constructive interference, like how the
Sound Field Management (SFM) option works in the JBL Synthesis Room Correction solution. However,the LSR 4300 manual says it supports 2 subs. So I would presume there is a way of dealing with them via the RMC software, but it looks like you need to use the 4300 series subs to do so. Let me look into this more.
