Re: 4 Polk Subs, PSW505's vs 1 High End Sub - Advice please.

For what you can buy a 505 for, it's a good value, for sure. However, where you're trying to go is the next level, and if you can easily sell them, you should. Everything Jim said about the horns is true. People have copied mikes f20, to good effect, but I seem to recall it was based around movie watching. If you're serious about building a horn, I would put in some more research. I don't know your skill set so I'm not sure about recommending a build like that. Rhythmik supports diy. Maybe a call to Brian Ding would be helpful.

Woodworking is easy for me, as well as soldering, I have both patience and aptitude. I would not feel comfortable building an amplifier from scratch. But I can certainly buy one and install it. I'm not sure how much more is required. Space is not an issue, I could build a huge horn, or two. haha But, I do love it when the bow is drawn across the strings of a Cello, and I want to hear the Bass string when it's struck. I was disappointed recently watching Jurrasic Park, when the T-Rex started walking, my room did not shake or quiver. If the "rear view mirror" and the "glass of water" start to shake, I kind of expect the room to feel a bit like that too.

Sounds like you've the skills! It might be worth looking into some horn designs. A quick search on Google will bring plenty of options. I can't say for sure you'll end up ahead of a well designed ID manufacturers sub. Especially if you're after articulation.

Forgive me, what does ID mean?

OK, thanks. Then I'll go ID. Sounds like a sure thing, easier.

You will get more articulation out of a good ID sub than you will a horn aimed largely at the home theater crowd.

Trouble reading subwoofer graphs

I am having trouble reading the graphs. From the graphs, it looks like this sub will recreate detailed music from 20hz and then stay strong and flat.
http://www.hsuresearch.com/products/vtf-2mk4.html


This sub seems to be only marginally better, maybe a flatter response? It looks to me like the same SPL as the vtf-2?, looking at the graph.
http://www.hsuresearch.com/products/uls-15mk2.html

I do not understand the following graph, I can't see like the previous graphs, where and how quickly the sub creates sound at 20hz, or how flat the response is?
http://www.rythmikaudio.com/LV12R_specs.html


Because my theater is in my garage, and my neighbors are very close, I do not want to bother my neighbors with throbbing bass. I want to enjoy music and movies, with the occasional wall rattling of an earthquake. In order to achieve this, I am putting lots of light weight tools and things on the walls and shelves. They vibrate and crash around quite easily. And I am going to keep the 2 Polk 505's and place them right behind the couch. I am inclined to go with the Rythmik up front, because of the servo technology. I think it will be more articulate. But, I am unable to compare apples to apples because of the differing graphs. My space is about 3200 sf.

Any thoughts?

Thanks.
