IDmax v3 or FI Q........! For super lows

[dftnz7 10+ year member]

You need at LEAST 1.5 cubes NET for those IDMaxes. What you are doing is like running an alcohol drag car on 87 octane and complaining about the outcome. Deep bass requires a larger enclosure, and without looking, I am sure an IDMax recommended enclosure is at LEAST 1.5 cubes.

1.3 gross, Im about .1 off.

Im probably going to try a 1.5 gross enclosure though..

That won't make much of a difference. You're barking up the wrong tree with a sealed enclosure for low end extension (unless you double your volume and even then...). A ported enclosure tuned in the low 20s will sound exactly like a sealed enclosure of the net volume from about 35hz and above and it would get you some lost output below 30hz. Or, you can just build a new enclosure at 1.5 gross and enjoy the same sound you have now.

Or, if you have a lot of power on tap, you could implement a Linkwitz transform circuit to reduce output above 40hz and then apply more amp to get the desired output levels. The only problem is that you would be running much more power to the 20-35hz region and could bottom out the sub.

Ive went +/- .3 before in other sealed setups and noticed a significant difference.

Then do what you want and enjoy your new setup. Go with whatever you think will be best because that's the only way you will notice a positive difference. The brain is a very powerful tool.

Sounds like you need to get off the "sealed sucks lolz" bs.

Please dont take me as rude and I dont necessarily mean to intervene, but have you checked out the specs on the new RD Sonance? I've gotten to play with a few.

They get pretty **** low. Pretty **** loud too And they sound amazing.

I have no problem with sealed boxes in the correct application. I don't believe that they are the best option for sub 30hz performance with those subs though.

Why would the Q's not be better for the lows, especially in a sealed box?

Ive read here and there that sealed is better for sub 30hz performance.

Look for some old Avalanches.

x2... rlp's are also a good choice

sealed has more overall control through the sub's spectrum... ported has more control around tuning..so if you tune low...it should be more in control for the lows
