Anyone else a little disappointed with the results considering the hype of the driver? it looks to perform very similarly to the UXL.
How do you see that it performs similar?

I don't know if I missed the THD results from the UXL earlier or if they weren't posted on Data-bass before but I see that they are up now.

How do you see that it performs similar? Referencing 100dB via Data-bass.com's results the UXL-18's roll off is at 36 Hz. The HST-18's roll off is at 26 Hz. It is also noted that Ricci stopped the UXL-18's distortion testing because the driver was having issues, where-as there was no mention of the HST-18 having any issues at all. All I am seeing is the HST-18 playing lower with similar HF extension compared to the UXL-18 with the HST-18 having actual distortion measurements taken on it. How is that similar performance?

I know that the distortion numbers are a little lower but how much of that is actually audible? Their output numbers are extremely close to each other are they not? And the UXL-18 had a small advantage below 20hz doesn't?

If you are Ok with with ticking from the driver and/or higher than average distortion your window for suitable drivers may be huge compared to others.

Your comparison view is not correct at all. The HST-18 has +3 dB more output at 20 Hz in the basic response and 2 dB at 20 Hz in maximum long-term output compared to the UXL-18. Drag down the comparison tab on www.data-bass.com and see for yourself. Full-range response yields +3 Db more output at 20 Hz for the HST compared ato the UXL. How is that similar performane?

For a true subwoofer the HST is my vote over the UXL. I like the UXL a lot but everything I have read now I am placing the HST above that one.

HST
ZV4
SP4
UXL
Ultra
TDH

But each one of those also depends on the enclosures. Again another great products from Nick.

Sorry, I was looking at the max SPL numbers which show the HST-18 at 108.2dB with 22% distortion and the UXL-18 at 108dB with 29% distortion.

Sorry I've never heard any ticking with my drivers. So I see that the distortion of the HT-18 at 20hz is 29% like the UXL drivers do they also have this ticking from the driver that you're describing?

Josh did not test the latest version.
When I visited Josh in December 2013, I saw the HST-18 and commented about it to Josh. I thought you noted in a post that Josh sent that driver back to you and since the recent test was done this month... wasn't this test done with the latest version of the HST-18?

If not, what is the difference between version 1 and version 2?
