[QUOTE="ciaonzo, post: 6540902, member: 607015"] No, I would never let go of your aspirations of getting over 145, it's certainly possible. I would just go with someone else's guidance to achieve that. Based on the type of driver it is and the market niche it was intended for, I'm sure Steve told you to use the Alpha in 2 cubes to get you the most output for your dollar. Regarding extreme dimensions for enclosures, it's like this. Long dimensions set up standing waves and if you build a tall, slim tower speaker you can end up with a standing wave for the half wavelength on the longest measurement. That will also have a large impact on the fundamental frequency response according to the quarter wavelength dimension and the 3rd, 5th, 7th, and 9th harmonics of that fundamental. The short answer is that for subwoofer applications, you won't have to worry about it because you're not likely to encounter any lengths long enough to have any impact on the frequencies within the pass band for the system. Build whatever size and shape you want. I think it's great that you intend to build a number of different enclosures because as the old cliche goes, there's no teacher like experience. [/QUOTE]
