| directional speakers Regarding the radiation pattern of ATC speakers which use that big 3" dome midrange on a shallow waveguide - As a general ballpark rule of thumb, a horn or waveguide starts to lose directional control below the frequency where its dimension in a ... | |
| Titanium Voice Coils - where to get best price? I agree with @erik_squires, that you’re unlikely to find an off-the shelf replacement for your woofer that is functionally identical except for the voice coil former. I think you’re also unlikely to find a recone kit for your woofer that has a ti... | |
| directional speakers @treepmeyer, in my experience interaural crosstalk cancellation works; it significantly expands the soundstage in width and depth, and enhances the sense of being within the acoustic space on the recording. I owned an electronic interaural crosst... | |
| directional speakers It looks like there is a divergence of opinion about how wide the speaker’s radiation pattern should be. Given that the BACCH-SP system is using the spatial information already on the recording to present an exceptionally wide soundstage, rather ... | |
| directional speakers @treepmeyer posted, quoting from Theoretica’s website: "An ongoing investigation of speaker directivity at Princeton University’s 3D3A Lab, has shown that dipole speaker designs, electrostatic speakers, as well as speakers with horns and wavegui... | |
| directional speakers @treepmeyer, did Theoretica give you any specific recommendations or general guidelines? Did they tell you why they recommend speakers that are "more rather than less directional"? My guess is that they want to minimize early lateral reflections, ... | |
| Titanium Voice Coils - where to get best price? @btlancaster24, no I don't. I use either off-the-shelf drivers or factory-made custom drivers; I've never sourced my own voice coil formers. There is a publication called "The Loudspeaker Industry Sourcebook" that lists sources for loudspeaker ... | |
| Titanium Voice Coils - where to get best price? @tsacremento, I think @btlancaster24 means Titanium voice coil formers. | |
| Free air, tighter bass - snake oil or cheap tweaks? @erik_squires, I like both of your ideas. Many years ago there was a company called Audio Concepts who sold to the DIY speaker builder market. They competed with Madisound and Parts Express and Meniscus. Anyway one of their kits was a medium-size... | |
| The D'Appolito, MTM Configuration Joseph D'Appolito's original design had a few characteristics which have not made it into everything "MTM". He used an odd-order crossover (3rd order), which would have a lobe at 45 degrees above the tweeter axis in a normal tweeter-on-top two-w... | |

| Dd67000 crossover points? The JBL 4367 is a passive two-way (15" woofer and 1.4" throat horn) with a crossover at 700 Hz. Imo it’s a good idea to cover the range from about 1 kHz on up with a single driver, and crossing over a bit lower than that would be even better as l... | |
| Speakers for weird sized room..... Long wall or short wall? If it's the short wall, then dipoles come to mind. Dipoles can be placed right smack up against the sidewalls because they naturally have a nulls to their sides, but they do like to have a fair amount of distance behind ... | |
| Subwoofer speed is in the room, not the box @erik_squires wrote: "Installing 1 subwoofer correctly is a big deal and a lot more work than most audiophiles want to do. Tripling the number of speakers (from 2 to 6) for SWARM is also a big deal for many. Failing to do either well is what makes... | |
| Maggies and subwoofer integration @jjss49 wrote: "sure sub swarms of 3-4-5 subs work well, but in the op’s 11x13 room it might just be overkill..." Multiple subs might very well be impractical in this case because of space constraints, or cost, or for other reasons. But assuming ... |
