I was thinking of porting my sealed setup but what is the point? I already don't use all of what I have, just building a better box to driver enclosure for better low end sensitivity like an IB should have.

I think this is a AVS Guinness record: The very first A/V related "video or it never happened" response.

Additionally... you might be the very first avs'er to actually PROVE a subwoofer performance sweep / REW chart via an online video.
(Nobody else has taken the effort or courage, those slackers! :p)

Correct me if I'm wrong, but I don't think anybody has ever posted their subwoofer response in real-time video on AVS before.

This is the "first sign" that I've seen that society is starting to reach "web 1.5" technological abilities, this is an important milestone.
As I've said many times already, pictures are so.... 90's dial-up :D







Anyways, enough about web-technology progression... ;)

Nice path!

I used to run the same mains and center... I really miss those mains :(
Thanks!

It was really interesting going back and looking at my upgrade path from a ULF score perspective. I remember when I first got into this hobby about 4 years ago when I purchased the eD A2-300.

It was absolutely awesome....based on my listening preference (-18db was the loudest I listened at the time...), I thought I was in bass nirvana! I had a 2.5 Star ULF system and was very happy! So, I can definitely relate to those that are satisfied with their entry level HT sub.

Ignorance is bliss. ;)

I love my Klipsch speakers. They are incredibly dynamic and great for movies and rock concert level sound! When I want to dial it back and listen to some jazz, classical, etc. that's where the maggies excel...and where the flat curve comes in for my critical listening. My HT curve has the bass jacked pretty good. :cool:

Why did you get rid of your Klipsch's?

Looks a lot better with the AT screen. How deep is the space behind your screen and what is the screen size before / after?
Thanks...I agree. :cool: It really changed it from a media room, to a theater IMO.

I've got around 28in from the frame to the wall.

@Fatshaft

Nice HT! Your subs look pretty menacing in the back!

I still can't get over your FR...crazy.

@BassThatHz

You are crazy sir...I get first demo of the 12 matterhorns...:cool:

You may not have to. What does your response look like nearfield?

Do you want to see if you have a ULF resonant frequency in your riser or couch?

You can use the Vibration Meter to take measurements and plot them against different frequencies. I did this with mine, and that's how I determined my HT seating gets energized between 10hz and 20hz.

Here is 40 horned 15's with 40,000watts.

(I'm not even sure if that was full blast.)

What ULF score is that?
I don't think any of us has topped this... yet!
Ivan won't give up the design... I'm sure Danley would for a price, but I haven't begun to explore that avenue. Hummm, it was initially designed for the military, so maybe they won't give up the design? Ha!

It does not fit into rooms so the room size is too big for a great ULF score.
Anything can be done if you start from scratch.
:D

Yes agreed, ignorance is bliss. I used to judge the worth of my early bass configurations strictly by how much bass they put out, not giving a single thought to how it sounded.

I sold the KG 5.5 and KLF-C7 to a friend of mine, but only after he promised to offer them back to me should he ever want to get rid of them. I sold the speakers because I went with a larger projector screen and needed small speakers to fit under the screen. Unfortunately, I couldn't accommodate an AT screen in my room, so it was either keep the KG's with a small screen, or go with a big screen and smaller speakers.

I was running a KV3 center, but then I wanted a lower screen height, so now I run phantom center with Crites CS-1 mains and 4 subs (4 star system). Good times.

They have a build-video which pretty much gives it away, basically 40 ICE 1000's powered by a big gennie and 40 15's (MTX 9500 / TC 15)

A 15" driver horn loaded x40. Not really all that hard to design. Just tough to build. Big and expensive. ;)
Guess we know who to turn too now for help.
:D

I've always had a few questions about the Matterhorn. Why the need for 40 individual amps vs. getting a few powerhouse amps drive multiple subs to save space and money? What kind of DSP work would go into the design to get it dialed in? I mean 40 drivers, each vertical row has a different distance from the horn mouth, so it seems like it would be a very tedious task to dial everything in properly. Maybe I'm just over thinking it and with a little time and patience anything can be done. It would be nice if @Ivan Beaver chimed in to provide just a glimpse of the secret sauce in the Matterhorn design.

I've seen some very great input from @Ricci about using multiple drivers in a tapped horn, but can't find the post...
:mad:

Hey Pop,
Do you have any response graphs from your near field vs far field subs? Raw ones?

Son of a....

Embarrasingly enough, no...I don't have the raw response graphs of near vs. far field. I have the raw response of just my front here. I have an "after" EQ response of just my fronts, then all combined, then inverting my nearfield here.

Clearly not what you asked for, but that's all I got for ya at the moment. FYI. The internal volume of my boxes (front and rear) yeiled approximately 3.9ft^3 for each driver.

Yeah, I guess I was so excited to start tweaking with my mini that I blatantly overlooked capturing the raw response of my far vs near field.

Won't happen again.
:eek:

It does not matter, any response is good. I was curious on how much boost you needed to bring up the low end of each.

More boost was needed than what I was expecting. Guess I was just jaded from the awesome motor tech of the LMS-U.

However, I was eventually able to get the redline as my ULFTard curve with a bit of miniDSP tweaking.



;)

Don't be disappointed in their low end response right off the bat, because it does take a bit of work...
