Subwoofer Stokes Posted July 26, 2014 Report Posted July 26, 2014 I have a Fi Q 18 that I ordered from Fi. I am thinking of building a 4th order for it and I like pure LOW notes. It's all going in my 97 c1500 ext cab. Plan to take rear seat out for my box. Most of the music I listen to is slowed. What would be the best type of box and the tuning for the port in your opinion? <p>Black 1997 Chevy C1500 Ext.

Joe X Posted July 26, 2014 Report Posted July 26, 2014 Pyramid EQ? hope the signal to the subs is not passing through it.

DylanBunch Posted July 26, 2014 Report Posted July 26, 2014 If you just wanna play lows then build a low tuned ported box, don't waste the wood and space for a band pass. But if you want lows while keeping a wide range build a band pass 2006 Ford Explorer 2 Team AA/Sundown 15s 6th order Ct Sounds 7k 4 PRV Mr500 8s Rockford p1000-2 Team Subsonic Lows
Subwoofer Stokes Posted July 27, 2014 Author Report Posted July 27, 2014 Okay but will the band pass play lows as well as say a 28hz tuned ported box? <p>Black 1997 Chevy C1500 Ext.

Call Me Dubstep Posted July 27, 2014 Report Posted July 27, 2014 Okay but will the band pass play lows as well as say a 28hz tuned ported box? I hate to be a Debbie downer here... but... that question you just asked... I mean you can generalize that yes it may, or may not... its kind of asking which is better, apples or bananas? one person may like apples, the other person right next to him might like bananas... Bandpass box or not... its basically all trial and error, you cant just have the perfect box unless you go out and have someone professionally engineering the box specifically for your listening wants and within your space requirements, which costs about 50-75 dollars for blue prints... different boxes will play differently in different cars... Its mostly trial and error, if you have enough space... otherwise you are limited on your options... Personally I would just make a ported box and stay with it... I mean I have a FI audio q 18 right now next to me. Im still planning on a box right now i decided with a ported box at 29hz that is about 6.8 cubic feet... so i mean that's what i am limited to... I barely can fit it in my car. 2000 Ford Focus ZX3 Mods: Raceland Coilovers Borla Exhaust Aftermarket Header System: Sony CDX-GT66UPW Pioneer 6x8's System Upgrades : Pioneer MVH-X560BT 2 sets of Rockford Fosgate P1683's Fi Audio Q 18" D2 ( Currently Own) DD M1C ( Currently Own) All SHCA Wires and stuff...

Subwoofer Stokes Posted July 27, 2014 Author Report Posted July 27, 2014 Well I have a 9.8 cube box in my truck right now but it's completely sealed. I was thinking of putting a port in it. What should my port be sized at for 28 or 29 hz. Not port length but the height. I want the port width something around 6 wide. I just don't know how tall I should make it for the right port area. <p>Black 1997 Chevy C1500 Ext.

There you go, that's why you are not getting the lows, the box size in sealed will not help you too much once part the max recommended size.
