BMS 18N862 would be my choice for going deep. 550lit box with two of those will have f3 of 27Hz.
You would not like the price :-)

30-80hz is too wide to make such a big peak. Chose either 30 or 80. Can not have both in a reflex.

Just to get back to the original question, I was just wondering if some of the more experienced people on the board would have any personal preferences on producing the best and deepest low end with reflex boxes, what would be the ultimate driver and box design to suit it to produce high spl around 30-70 hz. Thanks Tony for your input on your boxes.

And this might be a bit stupid question but when designing a reflex box for the previously mentioned frequency range,  would it be more efficient if there would be a peak in 30-80 hz obtained in the box design  when the box is only meant to play those frequencies and there would be dedicated boxes for bass above that frequency range?

Just thinking about different options for a reggae soundsystem based on reflex instead of scoops.
My DubsubSmile hybrid reflex/scoop also has a AC behind the driver

did not want to offend you!!! Smile
i just assumed the ported backchamber is to add a little bit to the low end, and the port looks really small for that purpose on the picture. but if it works the way it should, everything is fine!

That's cool bro. I spent hours trying different port sizes. You're right. This was too small. Its now more then double that size.the problem is.. different drivers need different size port.

If you take the front section away and leave the tunnel, this will help do away with the 'cancellation dip' you find in scoops
