Changing My Room Acoustics

Recommended Posts

A bit of an update everyone, I have combined a bit of the advice from a few of you and have got positive results!

Firstly, I have moved the left speaker to the right so my speakers are not set up symmetrical to the room.

The second thing I have done is increase toe in to get the cross point straight out from the tweeters to cross in front of me.

The last thing is I have got the speaker to point down quite substantially by using an extremely thick spike shoe on the back with Bunnings anti vibration squares under that and really thin spike shoes on the front.

There is now an acceptable amount of bass at my listening position, but there is still more bass when I stand up haha.

Not sure if the treble is more emphasised with the toe in or I have lost a bit of midrange but the sound is also a bit harsher or less warm.

Will keep tweaking and see how it goes!

Hi peeps,

 

I have recently changed speakers and after a few months of moving them around to try and get the best placement I have discovered something quite frustrating.

The bass gets cut off ONLY at my listening position. The moment I stand up from the couch, the bass is all there, sit back down and the bass is gone.

I have tried moving the speakers right back against the wall, I have tried moving the speakers reeeeally forward, and it does not help.

I know my setup is not ideal but I don't really have to much chance of rearranging the room, peace with SWMBO is much better than bass.

I'm thinking I need some sort of room treatment?

I have never done any of this before and would appreciate some suggestions as I do not know my bass traps from my reflectors.

Some pics of my listening area below.

Take the spikes off the speakers.

That sure is possible. Towing in means that you are aiming the center of the speaker towards the listener. The center of the tweeter usually is more efficient by a few dB than the off axis. That is also true for the midrange driver but the effect is less than with a tweeter.

 

You can't do much about the bass being stronger when standing up, except raising your seat up, or use bass trapping on the ceiling. Try your luck with the height of your seating positions, as sometimes small increments do make a difference.

 

Edit:

It is also possible that by moving and towing in your speakers that a first reflection point moved from a position where it previously was getting diffused by a cabinet/book case or absorberd by a curtain.

Will try that, it's a bit of a PITA with my speakers, they're 80kg each.

You can go to Clarke rubber and buy rubber black mats. This will also help plus not damage your floor boards.

Thanks for the tip, was a bit worried about that.

      Hey guys,
       
      I have recently decided to embark on a DIY bass trap build.. It seems most people in Australia have used the Polymax Absorb XHD 100mm batts. I have just contacted my local insulation store and they stated that the Polymax will take at least 2-3 weeks to build and get shipped to the Gold Coast. The guy I spoke to suggested the Bradford Supertell Glass Wool http://www.bradfordinsulation.com.au/commercial-and-industrial-insulation/underslab/industrial-board-blanket/supertel which they have in stock and sell for $230 for 2 pack of 3 x 1.5m (100mm thick). I have no idea about the performance of this product and I was wondering if anyone could shed some light as to whether it will be similar in performance to the Polymax (particularly in the low end obviously).
       
      Thanks in advance for any help!

      I have never seen a scientific study on the matter or even read an in depth discussions by respected reviews but what do you think is the most critical comment in any system? I could be funny and say the room or listening area. But I think we all accept, regardless of treatment, construction or design the room plays a huge part in the final balance of your overall sound. But let's ignore the room. And look at the gear.
      I'm going to cut to the chase here and say I agree with one comment I read quiet some time back that the most important component(s) is both ends. Yes more than one (not counting the room). If your media player sound is not upto scratch the final sound will never be "perfect". Looking at the other end, regardless of the rest of the audio chain if your speakers are rubbish the rest of the gear doesn't matter. So I do believe that it is both ends which are critical. I have even read that most preamps and powers (and cables if you think about it) will do a reasonable job. Provide you have top notch gear at both ends you have s good system. Right?
      Now I have to say that the biggest change and improvement I have heard in my system has come about by changing my power amp. The bit that is not meant to matter. Well it does. At lest it does for me. I have had some fab. comments from many others how good my system sounds will all my other gear in place. I loved it too and thought it unbeatable. The sound I like in my listening room. But the replacement of my power amp with a DIY Sure Electronics based Class D amp has totally change the sound of my system. And for the better by a mile. The power amp had in place was a very expesnive DIY 300B so no slouch.
      When I upgraded the Xovers in my DIY 2-way speakers to a third order I felt a huge lift in soundstage, focus and clarity. But still the single biggest change I have ever experienced is the inclusion of this 500W Class D amp I call ROBUSTO. Is it just the massive power or is it the new, now matured, technology?
      Let me know what you think is the most critical gear in any system.

      Hi All,
      Having recently bought a Dayton Omnimic V2 measurement system (thanks to site sponsor Paul Spencer/The Loudspeaker Kit), I thought I'd start a discussion thread for those learning how to use it.
      It certainly seems like a capable piece of kit, but I have a long way to go to become proficient in it's use. Hopefully other forum users could help those of us who are keen to learn, helpful tips and hints as well as pitfalls for the unwary.
      The kit comes with the USB microphone, a very small tabletop mic stand, 6' USB lead, case, software disc and test tones disc. The test tones are tailored specifically for use with the system. There is a 60 page Help Manual on the software disc which seems pretty comprehensive.
      Discussion of other measurement systems or methods are also welcome.
      Regards,
      SS

      Good morning … just a quick introduction … well probably long and rambling if the truth be known !

      I've spent over 35 years in the music industry, as a recording engineer, studio designer, commercial and domestic installer/system designer, and most recently, vinyl record cutter.

      I've never been musical in the "read, write & perform" sense, but have a deep appreciation of music, and how music & "sound" can affect us physiologically and emotionally.
      That's led to a bit of a life long quest:  To get that special "musicality" out of each and every audio system. To more than adequately recover the beauty, detail, weight and musicality of every performance for the benefit of our very hearts and souls.

      If I had an official title, and should the word even exist, I'd be an "acoustician" first and foremost, having realised many years ago, that the room is actually part of the system.
       
      With that in mind, as well as system components and their optimization I practice optimization on the room itself, and room acoustic qualities (or down falls !)
       
      I hope I can assist some members grappling with "boomy bass" and "floppy bottom" isues ....
       
      Karl.
