I will be completing a full review of the Stereo Integrity mkIV in the near future once I can get it installed properly. Right now, it is in a temporary box, but I can give some impressions based on what I have heard.
Information about the sub can be seen on the website (still under construction). Stereo Integrity Home
A little bit of background - I met Nick in 2009 at my first DIYMA meet that took place in Statesville, NC. I found Nick to be cool and very knowledgeable. He had a mkIII woofer and a Mag V4 to look at, and I was able to eventually get the mkIII for a review. Here is a link to the meet thread and my impression thread of the mkIII.
The mkIV has been in the works for quite some time, but it is finally in production. Nick contacted me to see if I would want to listen to the driver, and of course I agreed. I placed the box in the floorboard between the JL sub and the passenger seat. Here are a few pics.
I have used a variety of subwoofers in my BMW and in the BRZ, but I remembered how much I liked the sound of the Mag V4 that I had in my BMW and the mkIII that I had for a review.
Once again, I'm very impressed with what Nick has put together. I plan to explain the reasons why I like the sound of this driver. Stay tuned.....
Had the pleasure to listen to this sub yesterday for a little while in Jason's BRZ. Here are my impressions:
Listener reviews are subjective, so first let me say that what I primarily look for in a subwoofer is to disappear into the sound field as an low frequency extension of that field, fully integrated into the field.
This subwoofer, positioned in the passenger footwell of the BRZ, definitely disappeared into the sound field. I've heard good subwoofer installations before that did a good job at integrating with the soundstage on some music, but then making its presence individually known on other types of music. We listened to a good variety of genres on the sampler disc from blues to rock to folk to dubstep and the music always extended into the lowest octaves cleanly and seamlessly. Now that I think about it, though, I would have liked to hear some more kick drums of various types to hear how it help up in more dynamic situations, as most of the low frequency information we heard was more of a sustained note.
Guess we'll need to do lunch, soon!
Thanks Sam for that feedback. I certainly would like to get together to hit some rock / metal to see if it delivers the impact. Hopefully I'll have that voice imaging issue sorted by then
I had an incredible time with this sub today. From Zac Brown Band 'Different Kind of Fine' - very strong drum kit sound and strong bass guitar sound.
To Cirez D........at about 1:30.....my mouth dropped wide open while driving down the freeway = this is exactly what I looked like - the driver beside me must have thought I was crazy. Such incredibly deep, accurate, and tight bass. Bliss!!!!

I just listened to this on my ear monitors on the YouTube link you provided. As son as I get done typing this I'm going to search for the CD on eBay! Holy crap!
Actually, can someone help me find a way to purchase this song or the CD that this song is on (preferably the CD instead of the just the single song download)? I'm having no luck finding it.
Klippel tested linear excursion? I know the TW5 was designed with access to a Klippel.
The reason I ask is because going by manufacturer specs, the SI only has 27% more linear excursion, but depending on sd, that could be cancelled out by the tw5's larger size.
4?? How does that give space back :laugh: Is she a total bass head? If so, this might not be the driver for her. If she's an SQ enthusiast though, 2 of these would be more than enough.
Mike - I was talking to your lovely wife at lunch time yesterday, and she said the other day, 'her song' came on, and she turned it to '3'.........last night it hit me........that must mean -3.0 db on the Clarion.........I thought the system was loud at -15.0 db! The BOOM with no RATTLES!
Lol, I just showed her this post. Sadly, when she said "3" she meant the one on the other side of zero (+3.0db!). The damn thing only goes up to +6.0db! Luckily when 'her song' came on she was streaming from iHeart radio and the sensitivity of the aux inputs is lower than the CD level. So my voice coils were spared a meltdown, lol.
Guys I've narrowed my choice down to these or Illusion Audio. Either way they will be going in a hatchback. Having never had a hatchback, which way would you recommend they be installed? Down firing....up....front. ..back? Thank you for the input!
All of these methods could potentially sound good (in my opinion and in my experience). The two builds using the mkIII BM's that I clipped photos of above had them firing up in a false floor presentation. I know the one sounded great, and I could imagine Trevor's sounded good in the Volvo. When you weigh out the various compromises - that will likely determine your answer. Space savings, aesthetics, purely best sound, etc.......
Concerning the Cirez D......I haven't found CDs either - I think individual tracks can be downloaded from Beatport, but I haven't used them yet.
Here is another one that really impressed me on the mkIV BM. The beginning beats don't seem very interesting until the volume is turned up on a good sub system. There is a lot of detail going on there that the BM played flawlessly. I'm sure me previous dual 12" sub install wouldn't have been able to resolve that.
Thanks for the reply. I spend hours going through Trevor's Volvo build after you posted the pic the other night. My wife says thanks lol.
Where are you over in NC. I've been working in Cherokee for the past month....
