Popular Post Shimei Posted November 8, 2019 Popular Post Share Posted November 8, 2019 Hello fellow Audiophiles! One of the pet peeves I had while working in the automotive sound industry is that I was forced to place speakers in less than ideal positions. In turn, I was in the field of automotive sound when the first time delays and processors could compensate for less than ideal conditions such as the driver speaker being located closer than the passenger. I was also in the industry when "Wave Guides" or horns tried to compensate for the varying distancing by delaying the travel of sound through unequal horn lengths. Reflections, Reflections, Reflections everywhere. Sometimes they could be used in a positive manner and at other times they were a nuisance when the fad was using an RTA meter to produce a totally flat curve in the cab of an automobile. Well, now I'm enjoying home audio. And I have the luxury of placing speakers "ideally" in a location to maximize listening pleasure. Is it better to rely on processing or natural distance and reflections? I found this video rather informative and hope that it will help others in maximizing their speaker environment: GDK, semente and The Computer Audiophile 3 SMSL M400 DAC Bluesound Node 2i Sony 65 inch OLED A8G, Sony 4k Blue Ray X700 Parasound Halo A31 Amplifier Tekton Ulfberht Speakers w/ Be high frequency upgrade [4 ohms ea.] Two Tekton Active [300 watts rms] 4-10 Subwoofers Link to comment
Ralf11 Posted November 8, 2019 Share Posted November 8, 2019 try to put them in the best positions first, DSP later think about 2 freq. ranges: Bass & high freq. for Bass - avoid areas where standing waves either add up or cancel out - a swarm sub system helps a lot for HF - analogize to light rays - you can slide a mirror along the side wall and have a helper watch to see when the image of the speaker appears in the mirror BTW, what is a high quality single DIN head unit for an old car? one with no fancy lights Link to comment

That is actually what led me into this research. For example, in a car a 12" subwoofer may have a wave length of say 12ft. That's just an example and probably not accurate as there are so many variables with enclosure design. Pointing the woofer at the head may only have a 3-4ft distance. Whereas firing the sub backwards against the rear of the car where the waves reflect and reach towards the driver may be closer to 12ft. That's why firing the subs rearwards in cars sounds louder. My personal setup in the home I run Tekton Ulfberhts which house in pair 4 12 inch subwoofers along with the mid and high array. I'm currently piecing together the Tekton 4-10s for 20hz to 80hz impact. 4 of them which are 16 ten inch subs. I've always preferred smaller woofers to large woofer in my thinking of Newtonian law. The smaller woofers are more controlled. In quick bass successive notes or beat line larger woofers reproduce with a rumbling bass note, that is, 18s and 21s. But the smaller woofers reproduce the "distinct" notes in the successive bass lines.

cjf Posted November 9, 2019 Share Posted November 9, 2019 Agreed on doing the physical placement first to the best possible location as determined by test tones at x-over Freq and SPL meter at listening position (mainly referring to bass region here). The better the physical placement the less processing is required to correct things. There are lots of opinions on the large woofer vs small woofer argument. Some say the smaller woofer requires more movement to reproduce the same output of a larger woofer and in turn this extra driver movement always equals more distortion. I prefer fewer large woofers properly powered over many small ones that may each be well under powered My Audio System -Last Updated May 20 2021 Link to comment
