Well, this will be the first box for my new subs. 3.875 cubes per sub tuned to 33hz. Makes for a near perfectly flat response line. Port walls will be removable so I can tune higher for comps.

Edit: Just realized the measurements are from an old drawing. So a couple aren't right. Box is 49" wide. Port height is 16.625".

Feel free to let me know what you think.

 

That's gonna hurt... poor van

 

rolmao... I hope so. The van will take it. Might need more deadener. I can't wait to hear them that low. Most people with TF1's are running small boxes, tuned high, with loads of power. I'm going to try a big box, tuned low, on around 2400rms (to start). I have a feeling there will be a new amp in my future...

 

Yes, New amp will be needed !! lol...2400wrms might just tickle them..lol

 

Worse case scenario, I only run one for now....

 

I ran my 12" in a 2.25 cbuic foot enclosure tuned @ 31hz. Lost output on the higher end, but dug down deep on the lows.

 

WinISD and BB6P didn't like some of the T/S & Mech info I inputed for TF1 but at 3.875 the response is ruler flat. While I'd like it to get loud, I'm shooting for SQL. More power will come in time.

 

Well, after some input from fellow forum members, this is the design I will be building. Not likely the last, but we'll see. It's 3.5cuft tuned to 36hz. Almost 19.5sq" of port per cube. I'll still be able to switch up ports for comps.

THANKS to everyone for their input.

 

looks cute

 

it looks like a JL symbol :P
Hope it works out well for ya man!!
