I am looking for a woofer working in a closed box with a crossover frequency at 200 to 300 Hz. Above will be a bending wave wide range driver and as this has very good transient response and low distortion the woofer should match.
My present loudspeaker uses a version of that bending wave driver and an Accuton S280-6-282 in a vented alignment which was designed to be in a larger room freestanding. As my room is smaller I am trying to design a loudspeaker on the front wall corners (https://www.diyaudio.com/community/threads/on-wall-or-corner-loudspeakers.403432/#post-7458326 ).This would generate a significant room/corner gain and so I am thinking a smaller woofer in a closed box with slower roll off would be more suited. The box volume can be up to 60L but I would prefer a smaller box as this is easier to construct resonance free.
Design wise I like this Accuton cell driver and I see that it has quite low distortion but quite low sensitivity (not a big issue with class-D amps) and has quite a high resonance peak at 2kHz requiring something more than 1st order x-over. Hificompass measured that woofer but had a remark that the loudspeaker (Vimberg) he got it from had terrible bass.
I was also looking at Purifi PTT8.0X04 NABor 08 8inch or PTT10.0X04 NAB (not yet available). These are designed for good midrange performance but I would not use them in that frequency range. I am also not to excited visual design wise.
