Thanks.Nice Job Clausdk....
I'm sure you can easily notice the difference in SQ between the 2...
Gotta get some real grunt amp behind that LMS...
Still working on EQ settings.I know its early days but which of the two do you prefer? What are the defining features of each?
Thanks alot!Claus, I absolutely love how those turned out. Very, very nice work. The finish looks fantastic, and the glossy base is a nice touch. I still love the subtle curve of the top, and I really may steal your design if I'm able to do a dual MalX setup down the road.
So is the plan to replace the MalX's with two LMS if you decide you like it better, or are you going to keep one of each?
My guess is that if you reduce it with traps, it will give the impression of less weight on the bass. When I first tried traps, I noticed two things in particular. Firstly, it sounded like the bass had moved outdoors! It no longer sounds like that but comparatively it was the initial impression. It's a bit like when you suddenly notice the air conditioning noise in a room only when it stops. Secondly, it sounded like there was less bass, but I recognised that this was a time domain issue. It's hard to keep track when you keep changing EQ and crossover like I do, but I find I tend to run the bass a little higher. This increases the sense of punchiness and oomph in the bass and it becomes more visceral yet does not seem louder than before, even though it is. I find this more satisfying. Yesterday I had a session with some rock music and the improvement in bass punch is startling. Kick drums just have that extra attack. I think some might even find it underwhelming, the impression of less bass and as a result turn it up like I did.Alot of trial and error went into the 30-40hz area, but eventually I think I got it as good as I can with my current knowledge and experience!
Yep, that's easy .... the room!It's quite interesting to see your waterfall graphs and nice image switching for easy comparison!! Looks like you solved the 25hz, 40-50hz and 70hz problems, and beyond that just looks amazing really. Do you know what's causing your dips from 70hz onwards?
Just those 3 huge and horrendously ugly things. The rear one is now covered with a sheet. They are all about 2.4m high and about a foot thick to make up for being foam. All made out of what I had on hand. I'm going to experiment a little with seeing what happens if I squash the foam together to make it more dense. I may soon get some rigid fibreglass and see how it compares. Unlike most bass traps, I plan to use mine as midrange absorbers as well. The two front traps - one has a foam single mattress on the front and the other a small double. That's a lot bigger than most folks use where about 600mm would be more common.How much acoustical treatment did you end up with? Not sure it states that in your blog? Just those 3 big corner traps?
I'd think of it as a leak. As a membrane trap it would not be very effective because they are pressure mode and need to sit right at a boundary to work.I think it might act as one big membrane bass trap and it certainly vibrates in some scenes during movies!
That would be a membrane trap, like the ones on Ethan Winers old site. I believe those are much less effective as they are narrow band traps with a centre frequency of about 90 Hz. Handy in that they are unobtrusive, but fairly limited. I plan to add some as well, but I'd consider them "bonus traps." You'll find that Ethan himself pretty much suggests that people put in the broadband traps, as many as people can fit, and no longer strongly recommends the membrane traps. A typical room is actually like one big membrane trap, but generally not a well designed one and also one in which it works only over a narrow range. They need to be tuned at different points to extend their range. There is a good BBC paper online about modular membrane traps where you can see their range. Ethan recommends 6" broadband with a 6" air gap over a membrane if you can allow the extra space or 4" membrane if that's as big as it gets.I was thinking one 100mm trap each side of my TV behind the main speakers.
Try a free program like Cutlist. It should be able to put together what you need, if you have the rough dimensions.these are my favorite looking DIY subs i have seen yet. i would really love to build a couple myself as i think they are good looking enough to get past SWMBO!!
is anyone able to pen up some cut sheets??? i have tried using sketch up but i cant figure it out.
