Hi,
I've been a reader for quite a while, just registered on the site as it seems to have the best information available.
I have WinISD, and put the paramaters of this driver, a Dayton Titanic 1200, PN 295-400,and I'm coming up with very odd results. When I called PE about the driver, they have nothing on it. Where I'm coming up with a screwy number I believe is the listed SPL versus what WinISD calculates being off almost 20db (!). Obviously, it's not showing optimum output, but the cone excursion when ballparking PE's "recommended" enclosure size looks weird too.
Idea is a sealed 2.5 cu ft (70.79 ltr) sonotube, powered (for now) by a proficient M3, rated at 180w. This level of power seemed appropriate for this driver, and I'm not going for extreme overkill. I listen to alot of music, but this will be in my HT setup as well. AV receiver is a HK AVR347 powering several old Sansui floor standers (Kabuiki Theater!). Lowpass will be around 80hz, as I get respectable output before a steep roll off from the Sansui's.
I have an eclipse 88120.4 (TC 1000 dual 4) that I could use, but I think it'd be severely underpowered with this amp.
Anyway, if someone can assist on properly modeling the Old Titanic, I'd greatly appreciate it.
