As I stated before this video dropped, the QBombs are good budget SPL oriented prefab boxes. Can you do better with a custom built box? Of course but, but if you need something cheap and easy or catch these on sale, it's hard to imagine a better boom for your buck.

I feel like the audio community get so caught up on giving a stink eye towards the existence of prefab boxes that we forget that it’s not outside the realm of possibilities for a company make good quality boxes. Plus I feel like we judge prefabs too harshly without realizing that they’re not trying to be the best or win in any SPL lanes, they’re just being there for the newcomers who may have a curiosity or don’t really mind having something like these. After all, it’s like a wise basshead always says: bass is bass! 🔊🔊

I hear you, I think there's a lot of unscientific speculation in the world of box building. As far as I know the kerfed port is like an flared port--It reduces port noise. So it's really only useful if you're in a situation where you can't make the port opening big enough. I'm beginning to rethink the logic of putting a corner 45 in all four corners of a box. The corner should be the strongest point. So you're reinforcing the strongest point in the enclosure. I suppose if you have air leaks in my help. But if they were truly helpful then you would put a corner of 45 and literally every corner of the box instead of just four of them.

@DIYAudioGuy
3 жыл бұрын
Short answer, Yes you need a low pass filter to keep the high frequencies from playing. You will also need a tweeter with a high pass filter. Long answer, it's not that simple It might play up to 5,000 but it might not sound good a typical crossover point is going to be a little bit lower than that but the actual correct crossover point is going to depend on how low your Twitter can play. In the Tweeter specifications there's a resonance frequency typically you double the resonant frequency and don't let the tweeter play anything below that.

Nicely done! In my experience, the Placement of the port in the enclosure, as well as the location you fire the port in the vehicle, can dramatically make the effective tuning of the enclosure play a lot differently in the vehicle and make your overall vehicle response with the subwoofer extremely different than any modeling software can predict. unless you are a wiz at using horzrep 🤓. But also something to consider is the depth behind the sub to the back wall in conjunction with the port being on the same shared back wall can affect the effective tuning as well. But I’m probably preaching the the choir for the most part. Great video though awesome content!!

@@DIYAudioGuy the only program that takes into consideration the box dimensions and room (cabin) dimensions with regard to measurements from said room walls and the enclosures faces/or sides is hornsrep. But it’s very intricate and touchy. But im with you, I’m no expert either. What I think I’ve learned through all my builds has definitely help solidify the math and physics that i come up with when modeling. More importantly, what I’ve learned the most is that when I think I’ve got it all figured out and taken into consideration everything I can to predict the modeling the best, I unknowingly forget something and have to tell myself that I just didn’t get enough info and that’s why the response is not what I wanted it to be. Instead of just saying it’s a mystery. There’s always some type of math or physics behind why it does what it does, and I’m just trying to figure out all those things in my journey!!

I have owned a ported q bomb box for a 15” sub. 3.25 cu ft. Input a Rockford Fosgate P315 in it. I was amazed. The only 15 I’ve ever had. I had a ported dual 10” q bomb box for under the seat on my Ram that literally came apart. I’ve seen several come apart. The best prefab box I’ve used was a ported box from bassworx and I put a single JL 12w6v2 in it. I can’t imagine that sub in another box. Prefab- win some lose some. I’m guessing we get lucky sometimes not only with craftsmanship but also size.

@@DIYAudioGuy no, I used 2 JL 10w6 subs though. From the quality of most of the prefab Ram boxes I’m sure they’re meant for some 150 watt subs- not 600 watt subs. From all that I’ve seen separate, the subs being used were 500 watts each and up. Guessing too much force exerted on the boxes. They came apart in the middle, separating the top and bottom. Looked fine from the outside, but when bass hit it would come apart and make a slapping sound.

I bought the duel 12 slot port box from them late last year for 80$ it felt light and cheap. While i had a proper custom box built for my he2 15s so i decided to put my old sony xplod 12s on a r2 500x1 fosgate amp in a honda crx at 2ohm, set the gain with a multimeter and I've been listening to different styles of music, rock music sounds the best definitely but not impressed with the enclosure. The sonys do sound very good in a sealed enclosure, so i inverted the sonys and set the headunit to reverse sub output and they sound a bit punchier. I have no clue what the box is tuned to, there was no description. Im looking forward to getting the 15s back in the car. Thanks for doing videos like this. Hope you do the D4S enclosure review.
