Line array horns and THT+

#1 Post by Rich4349 »

Are line arrays and horns unconducive to each other *in the same cabinet*? Could something like the TLAH have the front of the enclosure extended (in a straight line, forward) to improve the bass response? The ungainliness of the size and shape would likely make this not favorable for frequent transport, so this is more of a hypothetical or home use idea. Would the sides of the distal flare(s) interfere with lateral dispersion of the high end? Could there be an intermediate length calculated and added, that would add *some* bottom end, while minimizing said high end lateral reflections?

Also, could the THT have one last flared section added on to both increase the dB of the bottom octave, as well as slightly lengthening the horn path, lowering said bottom end?

In before: "if these ideas would have worked, Bill would have added them to the plans."

Bill: are the peanut gallery's suggestions 100% irritating, or do they ever give you (constructive) food for thought?

Mains and subs of any configuration don't work well in the same cabinet. Mains must be placed where they provide the best imaging, subs must be placed where they give the best in room response. That's seldom if ever within the same footprint. THT goes as low as anyone really needs. TLAH goes as low as it needs to as well.

How do the Davids fit into these considerations?

Also, was hoping to produce the brown note. :shock: :)

It doesn't. I designed it for those who insist on an old school three way tower. Mine is in my workshop, where it works as well as that setting needs. There is no brown note, that's an audiophool myth. No instrument goes that low, not even the largest pipe organs. Some HT LFE content goes below 20Hz, but IMO it's only there because the guys who mixed it are having a laugh on those who use Audyssey or the like to see it on their PC screen, despite having speakers with no chance of reproducing it at audible levels. Look at an equal loudness chart to see why. It takes 120dB at 10Hz to sound as loud as 90dB at 100Hz. 30dB is a one-thousand fold increase in power. :shock:
