| There's a lot more bass in a 6.5" driver than most of you think Someday I suspect, when Jesus has definitely got us for a sunbeam, our works may be adequately assessed. | |
| There's a lot more bass in a 6.5" driver than most of you think For those interested in "room EQ", including bass, this is an interesting discussion that Floyd Toole joined and argued for multiple subs. It's fairly long, so for those with limited time I quote below relevant excerpts from dr. Toole's contributi... | |
| There's a lot more bass in a 6.5" driver than most of you think You write in your comments to Toole:"It’s 2020, who on earth uses steady state measurements?? "Toole does not give a definition of "steady state" in this paper, the readers learn it in EE101. Lacking that , some believe it is better to negate a si... | |
| There's a lot more bass in a 6.5" driver than most of you think Apparently we read different papers from two different universes, each with its own laws of physics. In your universe the definitions of physical states (eg. "steady state") follow circular logic. Let’s leave it there. As a parting note: "room EQ"... | |
| There's a lot more bass in a 6.5" driver than most of you think What is your definition of "steady state measurements"?Please note, this paper is from 2015, what changed since then in the area we are discussing? Dirac and others were there. Toole is not talking specifically about bass. He discounts the claims ... | |
| There's a lot more bass in a 6.5" driver than most of you think @erik.squiresYou wrote quoting me:" 02-01-2020 8:32pm>>When you EQ one sub, what you effectively do is ameliorate the modes situation at one spot (eg. your listening position) and make it worse elsewhere. It is easier to place the sub next t... | |
| There's a lot more bass in a 6.5" driver than most of you think @twoleftears Your quoted the Positive-Feedback report"Description of the Magnepan subwoofer accompanying the "condo" 30.7."The bass unit was about 3 feet tall and about 1 foot wide. The cabinet or structure consisted of a V shaped open baffle with... | |
| There's a lot more bass in a 6.5" driver than most of you think There is no complexity to distributed bass. Place three similar subs randomly along the walls. The flatness of frequency response is irrelevant under 20Hz. Actually 18Hz is often a safety cutoff point for infrasounds, especially if you use vinyl... | |
| There's a lot more bass in a 6.5" driver than most of you think Distrubuted bass addresses room modes, probably with more success than other solutions. Not sure what we are discussing here with respect to infrasounds (<20Hz). People can’t hear them, unless they are pure sine waves at big volumes. No concern... | |
| There's a lot more bass in a 6.5" driver than most of you think Please answer technically. Anybody can make any statements on facts. I am not trying to be omniscient here, but prefer to separate facts from opinions. | |
| There's a lot more bass in a 6.5" driver than most of you think Yes, mics can "hear" under 20Hz and software can visualize the measurements.How are "boomy" or "not boomy" infrasounds differently visualizedin magnitude curves? | |
| There's a lot more bass in a 6.5" driver than most of you think " @erik_squires 02-01-2020 4:31pmThe Swarm, when sealed, goes down to 18HzImpressive! I’ve gotten flat response to ~ 16 Hz with a single sub. Repeatedly. Not boomy. "I wrote before, that I stood once next to the 16Hz organ pipe and all I could fee... | |
| There's a lot more bass in a 6.5" driver than most of you think @noble100 Thank you.I started the audio journey as a hobby several years ago. I bought licenses from Linkwitz to build his LX521 and from another source to build the distributed bass. Then I moved to my own designs. It is still a hobby, but my sys... | |
| There's a lot more bass in a 6.5" driver than most of you think I have built both dipole and distributed bass systems. Dipoles are great for any kind of music down to the bass guitar low E (40Hz). Under 30Hz the experience is not impressive. The Swarm, when sealed, goes down to 18Hz. With the ports open even l... | |
| There's a lot more bass in a 6.5" driver than most of you think One more interesting concept is dipole bass, proposed by Siegfried Linkwitz in his LX521. The subs are v-frame dipoles and the side wall modes are minimized by cancellations. The bass is incredibly clear and tight.Finally, one can put the single ... |
