Default first project

Hi all,

I am about to start my first speaker project. I have been reading round a number of web pages manly linked to from hear. Any way I found the following project that looks nice and simple and low cost for a first time.

http://www.vikash.info/audio/standin...7&threshold=50

However I have also seen this wine bottle project on this web site and liked the Idea of cylindrical enclosures.

My Wine Bottle DIY Project

I have a good bit of wood work experience so what I was going to do was turn cylindrical sealed wooden enclosures for the TangBand W3-871S, with a nice flowing external shape but constant diameter internal cylinder to create the sealed volume for the speaker.

As in the wine bottle project I was going to use two enclosures and drivers per side I.e. 2 on the left and two on the right.
After all that rambling my question is should I use the same internal volume as the first project i.e. 2.86 litres in a cylinder form i.e. a cylinder of r 7cm d 18.5cm roughly?

That should be an interesting project. It is a good one to show your lathe skills.

I am assuming that you mean "litres" and not "decibels" correct?

Ideally the inside would be somewhat irregular to minimize standing waves. The ouside would ideally flow like the Fujitsu TEN or the midrange in the B&W Nautilus...

How are you planning to utilize 2 drivers/side? 1.5 way? Bipole?
