Hi,

Planning to built a pair of speakers. Full spectrum sound, good imaging, enough dynamic reserves. Plan to run these semi-active as I own a Lyngdorf system. Peerless XXLS 10" woofer in a closed box (qtc at 0.707) and using room gain, boundary effect and Lyngdorfs Roomperfect to get well controled bass that extends into the cellar

Active X-over at 200Hz, passive x-over somewere around 2 to 3Khz. Have not really made my mind up about mid & tweet, just too many choices.

Any thoughts about easy to filter mid-woofers that still have a good polar response at 2Khz.

Cheers
Huib.

Hi,

For the side mounted woofer the x-over frequency should be less than 200Hz, more likely to be about 100Hz the most is 120Hz.

My experience is that your OB mid-woofer will NOT go down flat to 200Hz, so 100Hz is impossible, unless you heavily equalized it using DSP.

Hi,

It's not an Open Baffle.

It's a regular box design but because the Woofer doesn't needs a huge cabinet I slimmed it down to make it optically as lean as possible (WAF). The small top cabinet is what normally would be the mid chamber within the bigger cabinet.
