fuzzydog Posted December 23, 2014 Share Posted December 23, 2014 (edited) I'm curious to hear the thoughts of our resident DIY sub guys on SI's new 11" subwoofer driver. Looks like they're targeting this for use in small sealed enclosures. http://stereointegrity.com/product/hst11-11-subwoofer/ Regards, Fuzzy Edited December 23, 2014 by FuzzyDog Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted December 23, 2014 Share Posted December 23, 2014 That is one powerful little driver. This would be great for a small room or someone needing WAF. One thing is for certain, a small driver like the SI will sound the same as their larger drivers at matching db/frequency. The main difference is power handling, FR and extension.

The main difference is power handling, FR and extension.im not one to call you out Derrick. But I will say that I already spoke with Stereo integrity to ask about this 11" driver vs my 18" drivers. They said it is capable of the same extensions which is impressive for a 11 to reach as low as the 18 he lever the laws still apply here. They said it will not have the output of the 18. So as with all subs. Extension, size, output. Only get two. This case you will. Get small and super low. But not a ton of output. I was very excited to buy these as I wanted to be the first Klipsch member to build a pair to put in my living room but it will either get another Svs PC or I will sell it and buy a pair of the 18's. You just can't beat 18 drivers for performance unless you physically can not fit them. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted December 24, 2014 Share Posted December 24, 2014 Fs of 17Hz, pretty impressive for that size driver. You'd have to have a STOUT box to hang on to that sucker once it gets going. Double baffle, tons of bracing. Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted December 24, 2014 Share Posted December 24, 2014 (edited) im not one to call you out Derrick. I agree with you. The point I was making is that at 20, 30, 40 Hz, it will sound the same as the larger driver. It just won't have the output as you raise the spl beyond the small subs operating range. SI has some great drivers. I would love to hear and feel that 24 in. driver by SI. Edited December 24, 2014 by derrickdj1 Quote Link to comment Share on other sites More sharing options...

I'd have to a/b them side by side to have a for sure opinion on that. In theory for sure. They should sound exactly the same. Hopefully a Kansas City member will grab one so I won't HAVE to lol Quote Link to comment Share on other sites More sharing options...

derrickdj1 Posted December 24, 2014 Share Posted December 24, 2014 (edited) An 18, 15 or11 driver producing 30 or 40 Hz at 90 db should sound the same at the listening position. Once out of the effective operating range of the weaker driver, then you will notice a difference in extension or output. The catch is that movies and music don't play on frequency and difference may become more noticeable sooner because the effective range of the weaker driver may come into play sooner.

CECAA850 Posted December 24, 2014 Share Posted December 24, 2014 I disagree. Let's use a sane SPL of say 90dB for example at 40 Hz. Both sets of drivers should easily be able to handle that. Both drivers need to move the same amount of air to create the specified SPL. The 18's cone area allows for less movement than the 11 to create the same SPL or same displacement. The driver with more linear motion (in this case the 11) will always have more distortion if all else is equal. Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted December 24, 2014 Share Posted December 24, 2014 If the smaller driver is operating in it's effective range the distortion should be very, very low and not audible. I was just having fun when I made that statement. But, It should sound the same. Just like a kevlar, paper, treated paper, cerametalic cone should all produce a similar sounding F or C note if they are constructed correctly and at the same frequency and spl, lol.

You always talk about cutting your 7's higher to have less cone movement and therefor less distortion. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted December 25, 2014 Share Posted December 25, 2014 (edited) Yep, that 11 would have to move over 2 1/2 times the amount the 18 would for the same SPL. Edited December 25, 2014 by CECAA850 Quote Link to comment Share on other sites More sharing options...
JL Sargent Posted December 25, 2014 Share Posted December 25, 2014 All that aside, the 11 does look like a HOSS of a driver. Quote Link to comment Share on other sites More sharing options...

CECAA850 Posted December 25, 2014 Share Posted December 25, 2014 I'd like to put 4 of them in a cube. A big HEAVY cube, with a few KW of juice and see what happens. Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted December 26, 2014 Share Posted December 26, 2014 I do agree that the small cone will have more distortion due to more cone movement. The distortion is not as easy for us to pickup in the subwoofer band below 80 Hz. Unless the small sub is pushed hard things should sound pretty much the same. I am in no way saying that the 11 in. driver is better than the 18 in. driver and in a foot race that the 18 would not win hands down. Either way, this was just for fun and I hope you guys had a great Xmas. Quote Link to comment Share on other sites More sharing options...
alexg5775 Posted December 26, 2014 Share Posted December 26, 2014 I have always liked SI and this is a very intresting little driver, being 11". This is for the person seaking a ht subwoofer requiring a smaller enclosure. If you have the room the 18" is clearly the better option. I wonder how this sub would work in a car?
