But anyone who is thinking of building one has to know that if you are after the 9Hz peak when The Incredible Hulk uses halves of a police car as boxing gloves, the horns are not the right tool.

Agreed! Except the DTS10's did this in room and this was not even close to their limits.

I get about the same, but have additional subs as well.

Remember for me these will be used outside. So I am more after mass spl really. At home I have a pair of sealed 21's for now. I will need a clone amp for them but I am more interested in building some horns again for outdoors. I wont be trying to go below 15hz really. But for budget I am willing to try a Micro for now.

I'm still planning on using my 6 x 21's along with any horn I make. Yes I can make it work, I've done it before and can easily do it again lol

Outdoor theater yes.

I cant afford to add a room to have a dedicated HT room. I love having friends over and so I figured I would just make a sort of portable outdoor theater. Mainly for fun but will try and get others, friends and at some point the community involved so others can enjoy it also. Either way horns are the go for me.

that sounds cool! I used to have a friend who had a outdoor theater. we were in the middle of nowhere so he had a bunch of DJ stuff and a huge old drive in projector his dad bought, it was always great fun!

That's the key phrase, "middle of nowhere".
I would love to do that, but I am not so sure the neighbors would be as enthusiastic as I would be.

That would be awesome to have a a couple bad ass horns and large screen.

16ft screen big field behind a school most of the times and biggish horns. Should be fun. Not fully happening yet but slowly getting there. These subs are the hardest thing to work out.

Glad that sub word was plural....that will be the hardest part in an open field...What are you planning for mains/surrounds?

So far just going to be building DR200's for all speakers. But may build 250's for the front. Figured I could use the subs as stands. SO I need 7 right....lol. I was thinking four subs and no more no matter what I build. Still have other things to purchase.

So, this is the view from the back of my room that is my living room that houses my home theater. This room measures 12 feet wide by 30 feet long by 8 feet high. While I'd love to pressure this room, it isn't sealed. To the right of the picture, it opens to a kitchen area (the kitchen area is 15X12). I'm talking about subs only right now. I've got 3 Klipsch La Scalas across the front, so for now, I feel good there. I currently have a single 18" sealed Dayton and it's good, but I'm lookin for more. I'm in the same boat as this thread (with a little more)...do I throw in a Gjallarhorn or Lilwrecker or just throw lots of sealed 18s and go for IPR 7500 or a clone? My goal is to be as flat to 10 hz as possible for Home Theater. Music is not an issue. Any thoughts or issues are welcome. Just wanna pick the brains of the audiophile geniuses here. smile.gif

If your wanting 10hz then you probably better just add more sealed subs. Both horns have tremendous output but will start to roll off before 10 hz.

10hz..... sealed. At least four 18's. If you have a huge amount of space and would be happy with 15hz then the LW.. If you have even more floor space the Ghorn. Cheapest option being the LW. Ghorn uses an expensive driver but for most on this forum that doesnt mean anything. So depending on how much floor space you have and budget those are my suggestions.

Where in the world would you put a gjallarhorn in that room? They are quite massive!

So I have been waiting for the UXL18 to come back into stock and I was going to build a small sealed box for it until we move and then I was going to build a GJALLARHORN with it, but I have been wondering how the Littlewrecker would compare to it? It seems the both dig pretty deep for a horn, but the Littlewrecker takes up less floor space and can be built for cheaper.

I am curious on everyone's thoughts as how these two compare and what are the pros and cons of both of them.

Thanks


In a nutshell? In actual use, from 0 dB to 120 dB, with a typical music or movie playback, they are essentially equal. The LilWrecker goes a bit deeper, the Gjallarhorn gets a lot louder.

In my measurements, the LilWrecker measured -3 dB at ~15 Hz and -10 at at 13 Hz.

According to the data at Data-bass, the Gjallarhorn measured -3 dB at 21 and -10 at 15 Hz.

The LilWrecker is larger than the Gjallarhorn, and uses a much less expensive driver.

So - you wanna get louder than 120 dB? Well, the LilWrecker would make smoke and bad noises if you tried to go for more, the Gjallarhorn would keep cranking for nearly 10 more dBs.

Distortion? Well, the LMS-U is a FAR better driver than the CVX..... it is really not even a contest.

How about dollar for dollar? If you could build more of the cheaper one and labor wasn't a big concern does this change things at all from a value perspective ?
