Thank you for the review and info.....Still waiting for an update on your upgrade. Just bought 2 of these JBL 550P Subwoofers for $189 incl. tax and free shipping. total for 2 was $379.98
Love this. Unfortunately, I look at sound systems in open spaces, so I look for ported subs and look at 21 inch speakers as.they.push twice the air that a 15 inch does. Pi r squared. When pushing outside, you need a deeper box and bigger cubic feet.
Very nice project. I know how confusing diy audio is if you furst start. But there are plenty of good resources. Snd above all, you will make experiences and learn from them
Hi Mike! I have the footage I just need to find the time to edit it. Work has been crazy this week, but I'm planning on having it done in the next week or two. Thanks for watching!
@@generationbehindhifi no worries the only thing about the Polk psw505 i recommend you put rubber feet onto them since you have wooden floor because they have wooden feet or at least if you have carpet idk
Great Video, and effort, but you are forgetting one HUGE HUGE thing. When you model the subs on your computer for the deep bass, you are NOT factoring in that almost all subwoofer amps have built in equalization, that varies by frequency. In other words, most sub amps, have about 5-8 db of boost somewhere between for example 30-40 hz or there abouts. So your calculated bass on the 10" JBL driver, is true for the driver alone, but not when connected to their specific amp they use. You can only truly see the bass by measuring the combination of driver AND amp, as they are a paired "unit" and rely on each other.
Hi Kevin! Thanks for the comment! Sorry! I was under the assumption that anyone who is watching this video is probably aware that if they enable any type of EQ or bass boost function, then the response curve will change. Just like the response curve will change on your front mains when you adjust the tone controls on your AVR or processor. At the end of the day its impossible for me to cover every possible scenario in every video, but I think I did a pretty good job of covering the basics and what to look for. I will try and do better next time and I do appreciate the comment. Merry Christmas, Kevin!
@@generationbehindhifi Think you are not understanding me. Subwoofer amps have BUILT in EQ, that is not user engaged, but it is on all the time. It is part of the amp circuit and not defeatable. That is how they get such deep bass out of a relatively small subwoofer box. Almost all sub amps using EQ, as a matter of fact. Not something the user does, but its on all the time, and boosts ONLY the deepest bass several decibels. That is why when you modeled the bass response, it did not go all that deep when using the T/S parameters. You forgot to factor in the built in subwoofer amp EQ that extends the response usually to around 30Hz or so.
As I said on the last video of this sub…was thinking about picking two up. I did. Now I’ll follow your journey further. I haven’t hooked them up yet as my AVR arrives today. The older 550P’s had speaker level inputs so I assumed I could try them out when I got them using my stereo receiver (Sony STR-DH190) and apparently I overlooked the fact that the new ones only use RCA. Doesn’t matter…just means I had to wait because my theater is getting upgrades anyway. I currently have no plans to upgrade components (driver or amp), but I’m excited to see how this CSS SDX10 performs for you. I see it’s fairly power hungry so I wonder about the factory amp handling the sub. I’m not saying I will copy your upgrades but if I do upgrade the driver down the road, I may seal up the box (was thinking some nice thick plexiglass and use an external amp to drive them. This of course is down the road if I find that they aren’t to my liking. I get the new receiver today along with a couple other deliveries so I will be cleaning up and arranging my dedicated space and we will see how it all works. I’ll need to spend some money on acoustic treatment for the space next. And I’ll be able to open up my old AVR (Sony STR-DG720) and determine the cause of its failure. Not worth fixing, but definitely fun to play with.
I think you will be very happy with two of them! The JBL 550P is by far the best bang for the buck I have ever seen in this hobby. Interesting... I never knew they offered the 550P subwoofer with high level inputs because the model I received only had stereo RCA or LFE inputs. So far the amp is doing just fine with the SDX10 and offered pretty decent SPL too. I will be doing a SPL video showing the before and after results and I think viewers might be surprised by just how much dB i gained with this new driver. Thanks for the comment and happy tinkering!

Enjoying these vids keep it up I just subbed
Awesome thank you!
Good job 👍
I have a Pair of the SDX-10's in a Dual opposed subwoofer. VERY good drivers !!
Very nice! I agree! I'm very happy with their sonic abilities.

Thanks! The project is coming along nicely. Once I'm done with my FrankenKlipsch project I will post an update on the JBL project.
We must be getting close to the next update on the JBL?! Lol. Trying to be patient.

Everybody should learn REW as well
I couldn't agree more! It's a very power free software tool.
The improved freq response in the review video is with the drivers replaced? Or can I mod the sub without replacing the driver?
Correct! You will have to replace the driver with the same one I bought if you want the same frequency response curve.
Parts Express has a 500-watt dsp plate amp, and while I don't see any dimensions, it looks like it'll fit perfectly in that box.
Hey Sam! Yeah, I saw that! I do have my eye on that one too. We will see. :)
You should check out the Polk audio psw505 it has 300 watts to 460 watts very powerful for a 12 inch im curious to see what the inside looks like
Thanks for the suggestion. I will keep that in mind. I'm pretty booked up at the moment though.

where's parts 2 and 3?
Part 2 was just released yesterday.
