Post Subject: Some thoughts in a positive directionPosted by noviygera on: 9/27/2011

Petar,

I thought for along time how to reply to your post. All my thoughts basically narrow down to this. You're a soulful guy. There is nothing smart I can say to add or subtract to you findings but I think that the result you will finally get from your LF "end of all searching" is a very refined and "soulful" signal reproducer. That's good to know because this "soulful" characteristic of sound has not been explicitly described anywhere -- as means AND the end of getting to the righteous result but now there is a rough guide.

So this 23" multiple woofers project of yours is part of the means to the goal. I believe that the infinite baffle is also a good idea. It will take you in the right direction but do not mount those woofers behind your listening position. I tried that and it's tonally good but it's confusing as hell to the brain even if crossed over 80-100hz, still confusing. Put them in front or on sides, where the main channels are. That's my experience.

Also, there must be a good ratio between the speaker cone area and listening room volume to get proper tonal pressurization of the listening room. What that area is I do not know but it is a lot more that two 23" woofers for a normal sized room, I believe (see ps note). I'd like to try at LEAST two per channel, positioned behind each channel.

Since you strike me as a person of soul, I would love to hear your result from using those 23" woofers. If they are good, why not make more and sell them.
I am currently looking at multiples of 18" to 24" woofers (Precision Devices or Hartley), even wondering about that 31" Fostex.

Thank you for your reply.

p.s from my experience of having a 500 sq. ft. listening room with 7 ft. ceiling and having two 18" woofers in a infinite baffle configuration, it is not enough to pressurize the room. I am talking about low and medium listening levels. Four 18" would be just acceptable. Eight 18" woofers in infinite baffle will be good for a 500 sq. ft. room so there is your rough ratio according to my experience.
