Default Cylindrical Speakers

Hi! Have you ever listened to any cylindrical speakers? How good they are? What are the pros and cons of speakers in such shape?

Besides those designed by Jim Rogers in the late 1970s, it seems not many cylindrical speakers in the market. The traditional box-shaped design has been dominating. I'm curious to know why.

Some say the standing wave problems are one of the reasons but I can't speak for that, I think it has to do with ease of manufacturing and that speakers have always been boxes so when incorporating them in with the rest of the interior, the "furnishing consultant" finds they blend better than does cylindrical.

Just a guess.

A little more complicated for commercial production, not enough benefits that support the additional cost to manufacture.

Hi...

I built a pair of cylindrical transmission line speakers a number of years ago... I made them out of 10" high pressure water line (PVC)... I can't really comment regarding sound (I've not compared them with 'box' speakers of similar design)... I like their sonic characteristics, particularly their sound stage... but I'm not sure how much of this is due to the cylindrical design..

But... They where a real bugger to build... Wouldn't want to build another pair.. And there is one other issue worth mentioning.... The materials I used where incredibly heavy... the speakers weigh about 135lbs each, and this combined with their shape, makes them nearly impossible to move... There just isn't anything to grab onto... And that makes them really hard to live with...

But hey, I'm not in a hurry to trade them in....

It isn't. Whoever programmed the star inserter apparently leans too heavily towards being a wus.

The meaning you were trying to portray has been totally misrepresented. Your post now reads that your project gave you a six star building experience. I am quite sure this is not what you meant.

Got any pics of your plastic water main pipe speakers that you care to post?

Something like that.

Keep in mind that in different parts of the world, it has significantly different connotations.

We wish to cater to all at diyAudio. Thanks for your understanding.

I recently made a lightweight cilindrical cabinet:

http://groups.msn.com/luidsprekers/f...to&PhotoID=305 (click next).

Inner skeleton: http://groups.msn.com/luidsprekers/p...to&PhotoID=283

Benefits of cilindrical would be a smaller rimple in the frequency response and the round shape is better suited to withstand pressure (the reason why gastanks are never square or rectangular).

Thing is about most cilindrical enclosures (talking subwoofers now, hmm wrong forum?), because they 're downfiring, with the port up, it's difficult to pinpoint the position even if standing up close or crossing higher as 80 Hz (which is good). They do however ratlle the floor much more (in case of wood) which can be good (can be bad )

Take a look at the SVS subwoofers as well.
