STL D Posted May 13, 2015 Report Share Posted May 13, 2015 I am expecting solid numbers from this one. Link to comment Share on other sites More sharing options...
Infrasonic Posted May 14, 2015 Report Share Posted May 14, 2015 Got to hear these, finally over at Archaea's house. He has eight of them all sealed with five up front and three 'nearfield' behind the main seats. These sound great! Link to comment Share on other sites More sharing options...

He has eight of them all sealed with five up front and three 'nearfield' behind the main seats. These sound great! They do sound amazing, especially considered the price. I love mine. I'm definitely curious to see what the actual performance differential is between it and the HT18. Link to comment Share on other sites More sharing options...
Infrasonic Posted May 14, 2015 Report Share Posted May 14, 2015 In real world use, they would be nearly identical. I have eight HT18's and compared to Archaea's eight Ultimax18's... I wouldn't say one 'sounds' any better than the other. They both sound very good and are a good value. The UM18's look better though and one could argue that the cone is much more durable which can be useful if you have a house with small children. The HT18's have the advantage of two voicecoil choices, d2's and d4's. I prefer d4's so that's nice to have the option. Link to comment Share on other sites More sharing options...

Just curious if it really narrows down to the dayton between worth the price differential or not. It's been a debate with no answer thus far, so this testing will finally answer it. The UM cone though... It is practically bullet proof. Thing may as well be a chain mail cone. Link to comment Share on other sites More sharing options...
mojave Posted May 18, 2015 Report Share Posted May 18, 2015 Looks like some measurements are now available. http://www.data-bass.com/data?page=system&id=116 Link to comment Share on other sites More sharing options...
Ricci Posted May 18, 2015 Author Report Share Posted May 18, 2015 Man That was quick...Geez. Let a guy close out the upload browser at least! I think you may have been seeing it before I even turned the visibility on? I just did that a few minutes ago and you already posted about it 25min ago. Weird.

Infrasonic Posted May 18, 2015 Report Share Posted May 18, 2015 Haha! Suck it, Josh! Erm, I mean... thanks bro. UM18 is a solid performer. Link to comment Share on other sites More sharing options...

The data on the JTR Orbit Shifter Pro looks very impressive. I'll wait until you are done to post the link. Link to comment Share on other sites More sharing options...

Ok...What in hell are you talking about!? I have publicly posted zero data on the OS-Pro and there is nothing on DB about it. I've literally uploaded zero data on it or any JTR product. Are you joking or what? Post the link or send it to me in a pm. I want to know how in the hell you are seeing things that should not be visible so that can be corrected.

Ricci Posted May 20, 2015 Author Report Share Posted May 20, 2015 You got me...I figured you were having fun at me. UM18 gets the thumbs up right? I think it does real well. I believe Daytons MMS spec is off. I asked them and the said it is calculated not physical weight of components. Link to comment Share on other sites More sharing options...
lukeamdman Posted May 20, 2015 Report Share Posted May 20, 2015 UM18 is a winner in my book. Link to comment Share on other sites More sharing options...
boober Posted May 20, 2015 Report Share Posted May 20, 2015 UM-18 definitely gets the thumbs up! Thanks Josh for testing this out, you've helped make my decision on which driver will be my next one. And also a BIG thanks for all your testing and work on the forums. Link to comment Share on other sites More sharing options...
STL D Posted May 20, 2015 Report Share Posted May 20, 2015 Definitely gets a thumbs up. It's a beautiful driver with solid output and is practically indestructible at a great price. Right now is an awesome time to be in the DIY segment. No matter what your budget is, you can build a great sub for your buck. Link to comment Share on other sites More sharing options...
Hifisound Posted May 26, 2015 Report Share Posted May 26, 2015 Any specific comparisons with RSS465HO ? Apart from slightly higher SPL with UM18, both look similar in the measured data. ( Even though HO show a much higher F3 in modeling ) Link to comment Share on other sites More sharing options...
mlah384 Posted October 28, 2015 Report Share Posted October 28, 2015 Am I looking at the charts wrong? Or does the UM18-22 outperform the HST-18 at 10hz?? I gotta be reading that wrong? Link to comment Share on other sites More sharing options...
