Areo or slot

So much fail in this thread. The one guy giving solid advice is acutually super knowledgeable and debating with a self professed genius or something.
As far as my advice goes stay off this toxic thread and let happen whatever happens.

Do you want to start **** also? I've been talking to the guy since last night. Now, you guys want to come in and immediate start talking shitt. I even told him to contact you and Buck. Wtf? I already told him that I wasn't a box building genius. I don't get it. I actually gave you a compliment to the OP, yet, you still have to start **** with me. We can do this all night, it's up to you. Your move "keyboard warrior". Sorry OP, I'm fukking tired of these guys riding my jock.
 
Yeah i got drunk again. Thanks for the welcome.

I've been talking to the OP since last night and everything was perfectly fine. I even recommended Shredder and Buck to him. But, HLSPLS and Shredder had to pop in and start talking shitt about me. I don't get it. I guess that they want beef. It might be a long night.

On the internet, the first one to get mad loses. It's also impossible to know their tone. You should always read posts optimistically. Sounds dumb but i find it helpful.

And, they are the first ones to get mad. That's why they start with the name calling. I'm not going to kiss anybody's ass or back down from anybody. I don't roll like that. They are the pusssies that have to call people names. Keyboard warriors. I even gave Shredder a compliment and he still started shitt. Fukk that. How are you supposed to read posts optimistically when you are being called names? I'm not going anywhere. I'll stand up for myself every time.
 
You had to start ****, you couldn't help yourself.
Apart from the part where you suggested OP reach out to Buck or Shredder your """advice""" here has been poor and based on zero real world experience.

Some dude you know drops 30,000$ into equipment into some 4th order and breaks 160dB and now you're convinced that 4th order bandpass is why he's that loud and that 4th order is the silver bullet for anybody to get loud. You come right out the gate telling OP that 14 cube for a pair of 15s is too large when you have never seen his subs, never looked at specs of manufacturer recommendations, nor build a large box yourself. Then you give port advice when it is likely you have never built a box and tested several different ports for comparison, nor read the Salvatti white papers which is the definitive resource on port design.

4th order is crap most of the time. If you want a decent flat/musical response you are approaching sealed box efficiency. There are very few good applications for that alignment and modelling the subs first is critical to know what you can even accomplish.

Anyway, just quit chiming in on stuff you have no experience with and don't understand.

Who broke 160 in a fourth order? The guys I know who broke 160 have done it in a sixth order. I've looked at a lot of different 15" subs and have yet to see one call for 7 cubes ported, have you? The biggest that I can think of is a Kicker L7 15" that like a big box around 6 cubes. I still stand by a 4th order blow through with 3- 15's. I also stand by what I said about changing the amp(s).

I think Pop came right out of the gate questioning 14 cubes for 2- 15's, not me. Do you really think those Rockford subs call for 7 cubes each? Why didn't you call Pop out? I think that I was the third or fourth person to question all of the cubes. 3- 15's in a fourth is his best bet. And, change the amps. Kiss my azz!

with 55,000W and 1600 square inches of cone area. The vast majority of the youtube bandpass builds (and really everything besides the top secret stuff that DB Drag leaderboard top 5 guys use) would do the same numbers in sealed box with the power and cone area they run.
Even Terry Brock doesn't use any of that nonsense in trunk builds that BTFO everybody else in trunk classes by 5-6dB.

Yes, some of the Atomic SPL lineup, in fact there was a guy on this forum within the past year talking about them, and Shocker Mike always told me sigs gain up to 8 or 10 cube then you do better with 18s. DD9515 do very well in >5 cube boxes as do Fi SP4. I'd imagine several more similar design concept 15" subs will also gain efficiency up to about 8-10 cube per.

I've done a lot more testing with 12s and with that motor a 12 will be louder than a 15 right up to almost 5 cube so I have no reason to doubt Mike's testing with larger cones. Anyway, I don't think anybody commenting has ever used the subs OP named so why comment if you haven't used them, haven't modeled them, and haven't tested any 15" sub in a lot of airspace?

Kicker square 15's are cone area of a round 18 and will want a lot more space than Kicker recommends. I've played with a couple Solo X 18s and seen a good bit of Kicker in the area besides and guys that do good numbers with them use boxes nearly double kicker recommended.

Anyway, the reason manufacturers claim less space is because they know the consumers are mostly ignorant goons that only care about bragging rights as to how much cone area they have and how big of a number is printed on the heatsink of their amp (or the more savvy consumers how much Steve Meade dynos out of that amp). The company that promises the most cone area in the least volume will sell more and larger woofers. DC made a name for themselves like this and Kicker had a great run with the original round solo-baric with the same marketing. In both of their defense both do perform well in smaller boxes, but also both will gain with more volume behind them.

Why didn't you call Pop out?
Because he has significantly more experience and just asked the question. And a valid question since that is on the high side and can get into mechanical trouble. You'll notice OP tried less airspace, wasn't happy and was happy with them in 6 cube each. All things being equal he will gain output and efficiency going up to 7 cube provided he isn't at the mechanical limits of his subs.

Build more boxes, test every variable you can think of, buy a meter and take measurements, lurk more.

Whoa, that will be one skinny port. The width of the back wall ports will be 1.08" wide (27.5mm), but the front port will be shared by 2 subs so...
