A quick question related to my plans on an "Idunn 2.5" speaker (the whole thread with XO:s and cabinet ideas is here: http://www.diyaudio.com/forums/multi-way/290262-seas-idunn-2-5-a.html).

For a parallel cascaded 2.5 speaker with two identical woofers (Seas U18 RNX/P) are there any cons for using a single chamber for both woofers instead of two separate chambers? This of course implying that I intend to tune both chambers to the same frequency and double the volume for two woofers in a single chamber and change reflex port(s) accordingly?

Sreten beat me to it... Just ensure that you have sufficient volume for both drivers; I was recently given a pair of low end consumer speakers that had two drivers in a volume that should have been twice as big - removing one driver & covering up the hole vastly improved the balance of sound

The lack of volume shouldn't be an issue here. It'll be 40-50 (effective) liters for two 6.5 inch woofers depending on how stars align regarding outer dimensions, bracing, available reflex ports etc. Probably closer to 40-45 liters at 35-38 Hz tuning or so.
