| Why the obsession with the lowest octave "a THERORETICAL -3db, who cares what you guess a system will do." - Acoustat6Theory is not the same as guessing; it's what designers use in the design stage. Dukespeaker designer | |
| Atma-Sphere MA 1's Amps and Magnepan 1.7's I drove a pair of 3.6's with early-generation MA-2s for a while, and they sounded magnificent. I have it on good authority that the MA-1 likewise sounds wonderful on the 3.6. I don't think you'll need the Speltz autoformers. The MA-1s will almost ... | |
| Why the obsession with the lowest octave I'd choose quality bass down to 40 Hz ballpark over somewhat muddy extension down into the bottom octave. An honest 40 Hz is pretty darn deep anyway.That being said, recently I built a semi-custom four-piece subwoofer system for a customer, and th... | |
| Hi efficient speaker, bass problems Unsound, I don't think the ear can hear all of these lags in the bass region.That's one of the reasons bass is perceived as omnidirectional inside a room: Our time-domain resolution is so poor down there that the ear/brain system cannot tell the d... | |
| Hi efficient speaker, bass problems What I've been talking about above might be called "room gain complementary tuning". Let's look at a couple of well-documented examples. First up, the little Guru QM10, which defies expectations with its bass extension into the lower 30's. When pl... | |
| Hi efficient speaker, bass problems "Duke, some of us are not so enamored with the sound of most loudspeakers with ported bass." - UnsoundMe neither! But remember that unless you're outdoors you never hear the bass independent of the room. The bass of most ported-box speakers isn't ... | |
| Hi efficient speaker, bass problems You're absolutely right Timlub - my bad! It was indeed Lewhite I was responding to! Thus dissolves my illusion of infallibility... Okay to answer the questions which I think actually did come from you this time, the subject of room interaction dip... | |

| Why do subs sound bloated or slow? "Many subs have group delays of up to or more than 1 cycle. Of course this is audible."I don't remember the exact group delay figures used in the study I read, but they were consistent with what one would expect from a well-designed vented system.... | |
| Why do subs sound bloated or slow? "Under many circumstances, optimizing frequency response and optimizing transient response is a zero sum game. In other words, getting one right usually means you get the other wrong."Strongly disagree. When you get one right, you get the other on... | |
| Dali Helicon 800 or Acoust Zen Adagio in this room Thank you for providing the drawing.Your room is effectively quite large from the standpoint of bass energy, and large rooms tend to make speakers sound "leaner" than they would in a small or medium room. I'd suggest going with speakers that tend ... | |
| Help with used "rock" speakers under 4K That's a very large room. In my opinion, speakers that have a good dynamic capability and smooth power response with robust bass tend to be good candidates for a very large room (think "prosound-style but with smoothness and deep bass"). One way t... | |
| Hi efficient speaker, bass problems In my opinion a fairly high output impedance (low damping factor) amplifier actually works extremely well with proper loudspeaker matching. In the bass region, a high output impedance has the effect of raising the woofer's electrical Q, which redu... | |
| Go for sub or larger speakers? I have some design experience with large full-range speakers and roughly comparable satellite/subwoofer systems, and imho done correctly the latter will have better bass quality and no audible integration anomalies. Duke | |
| Front port vs Rear port The audibility of coloration from a delayed signal gently peaks at about 2 milliseconds as I recall (based on an AES paper by by James M. Kates), corresponding to a path length difference of about 27 inches, but remember that the point of origin f... |
