| Maggies and subwoofer integration My understanding is that the more distributed bass sources you have, the smoother the in-room bass. To a first approximation, a dipole can be thought of as two monopolar bass sources 180 degrees apart in phase, and separated by a path length. Thu... | |
| Subwoofer speed is in the room, not the box @erik_squires wrote: "The biggest problems I’ve heard/seen have been excessively large peaks in the subwoofer range. Sometimes those peaks put out 20x more power into a room than the rest of the subwoofer. Think about that!! Your 1000 W sub is pu... | |
| Class D Amplifier(s) for SWARM Subwoofer System @peter_s , it's not apparent to me where the lack of gain is coming from. With the JL Audio CR-1, do you have plenty of gain? The Dayton amp just has a single channel. The two sets of output terminals on the back are both connected in parallel ... | |
| Class D Amplifier(s) for SWARM Subwoofer System Hi @peter_s The Swarm with Dayton amps "not being able to keep up with" your 87 dB speakers puzzles me. I've use the Swarm with an Edgarhorn system, claimed efficiency 107 dB. The Dayton amps easily had enough gain. How are you getting... | |
| Legacy Focus plug rear ports? I make speakers that have multiple pluggable rear-facing ports, so imo plugging ports is a viable means of improving loudspeaker/room interaction in the bass region. Plugging some of the ports will lower the port tuning frequency, causing the low... | |
| Favorite Obscure Rock Song These are arguably trend more towards "progressive rock" than "mainstream rock". Apologies for not picking just one: "The Camera Eye", Rush "Moths", Jethro Tull "Astronomy", Blue Oyster Cult "11:59 PM October 30th", The Changelings "Rajah Kha... | |
| All speakers have a little EQ built in @akgwhiz wrote: "@audiokinesis can you expand on how low, or how much of the phase curve that’s low inductance, at low impedance is acceptable for most tube gear?" The interactions between the speakers’ impedance curves and the tube amps’ output... | |
| All speakers have a little EQ built in As one who occasionally dabbles in crossover design, often with one eye on the frequency response curve and the other on the impedance curve, I’d like to toss out an observation: Equalizing a frequency response anomaly without introducing an impe... | |
| Is Anyone Using Subwoofers the Same Size as Their Mids? I use four 10" diameter subs in my system. Depending on which speakers I'm using, my midwoofers range from 10" to 15" in diameter. In general, subwoofer drivers are optimized for subwoofer frequencies, and midbass drivers are optimized for midb... | |
| Speakers - Your "Safest" Choice @gnoworyta wrote: "What I was trying to get to is the speaker that you or others think are a "crowd pleaser" (for lack of a better term)...." I understand the appeal of a safe-bet "crowd pleaser" speaker, but imo this is an unrealistic expectatio... | |
| Which is better, a fussy speaker or a versatile one? To the extent that amp + speakers + room = "a system within a system", compatibility and adaptability are arguably desirable qualities for a loudspeaker. Duke | |
| What happened to my room acoustics In my opinion: "There is a roll-off before 20kHz.." This is the shortest wavelengths being absorbed by surfaces in the room. "A dip is present around 12kHz.." There will be a on-axis cancellation dip in the response with a round horn or roun... | |
| Horns with good timbre and tonality? @phusis wrote: "What about, and maybe when is the diffraction part most troublesome here; what’s inherent to - as a distinct sonic imprinting/coloration - the narrow slot section leading up to the horn widening at every volume level (i.e.: at low... | |
| Distributed Bass Array Speaker Placement Arrival times are not critical in the bass region, at least not within the range of delays arising from the subwoofers being different distances from the listening position. The ear’s time-domain resolution is poor at low frequencies. We cannot ev... | |
| Subwoofers: Ported or sealed? @jaytor wrote: "[Open baffle subs] don’t pressurize the room like a conventional sub - the bass is there in the room. For music from traditional instruments like double bass or kick drums, this sounds very natural. These instruments don’t pressur... |
