Sub-woofer fast enough for Horns?

One of the most knowledgable sub designers is Tom Danley who developed the phenomenal servo belt driven driver motor. If anybody can speak to the original posters question I'd suggest him.

Some interesting responses that go right over my head. I honestly can't say if this has any effect on the time aspect of a subs delivery. In the seventies Techniqs (Panasonic) marketed a line of speakers with staggered driver units keeping the driver motors inline with each other. B&W followed with their 800 series.

Going from a single 18" to two 12" subs I changed sub location to the outside of the main speakers and slightly forward of the mains baffle. While the Velodyne EQ plot looked like a smoother starting point I honestly can't speak to any sonic advantage. Looks good though.

Not enough info, as others have said.

Regarding "fast", there is no such thing as "fast" 60hz, or 50hz, or 40hz, etc. They all travel at the speed of sound and have periods (the time for one wavelength) equalling the reciprocal of the frequency.

Many "perceive" speed or lack thereof based on distortion. High second order distortion at lower frequencies is the bane of many loudspeakers and subwoofers. Adjustability is a real plus in a crossover. The key is getting a low distortion subwoofer with a crossover that is steep enough for your main speakers to not have a bump in the upper bass where they overlap, which will also cause you, I think, to say the bass is "slow".

Vapor, I think we're not taking about horns being faster than a diaphragm but high frequency being faster than low.

Timing is timing: if this user is finding the timing is disconnected or does not match his horn loudspeaker it seems that there is a disconnect. I recommended a front firing sub placed forward in the set up if possible works like magic.

Horns are faster in the sense that they can increase both the dynamic range and spl by as much as 5db making them seem faster as they are often more in your face.

Q

Sorry guys, my horn is Cessaro Chopin. Their smallest model. I think it goes down to around 30Hz on paper. I am very happy with most music but not enough for electronic and heavy rock. I had Thiels 3.6 before and I think the Thiels has stronger bass.
