have to agree, higher tuning doesn't bring any benefit. I simulated single L15P200AK in a small reflex. if you high pass it BW 8th order  at 80 Hz, you can give it the stick until it runs into the thermal limit without exceeding xmax. With 1600 W (rated peak power) it will dish out 127 dB

i dont know what i was thinking wen i wrote this most 15" drivers should play "ok" upto 800hz

...ya just wouldnt,  theres a few other cabs iv looked at too...




i am looking to take the 15"s out of these cabs that i have:  http://www.bob-audio.com/en/FS252.php
and build something similar (single cab per driver)
i currently run these over top of two super scoopers, sounds good, but because the BOB cabinets are so tall it makes it a pain to set up by myself, also very heavy.

is anyone godo with designing things to a drivers specs?  i cutoff at 100Hz for the scoops and run these over top.  it also has a 2" compression driver in it with what i assume is an internal passive x-over
i will likely put these comp drivers in their own box with the passive x-over in it, or run them spereately with other tops off another amp in the future....

the quoted design above looks pretty good...i suppose it is a question of measuring the box they are currently in but it is trapezoid in nature and i am not so sure on how to calculate the port length and opening size as its a weird design inside from that perspective (shelf between comp driver and the lower part, ports on either side of the comp driver etc etc

any help would be awesome
