    When I am looking to have music playing throughout the house (small house) and also wanting to make sure that I can stay at a fairly low price (Thinking POLK MC80's) should I consider buying some 'caps' for the speakers to prevent any conditioned air from leaking out through the speaker? Or are...

    I have been doing alot of modeling and thinking about this plan. I think I have a solution and wanted to get your thoughts on it. Looking to try to maximize performance on a budget here and still be able to place the speakers behind the screen. I have about 115 watts per channel available. I...

    Looking to build some high efficiency in-wall speakers. I don't have depth to do a compression/waveguide. I ran across this tweeter......the only thing is the frequency response drops above 10khz. This fits the budget, size restriction, power handling and output potential. Just concerned...

    After reading through the entries in this forum, I am somewhat embarrassed to post this single driver experiment, but it sounds so very very good. I will now take the nasty cabinet and transform them into something that can be displayed in public. This build started as an idea by a friend that...
  5. DIY Subwoofers - General Discussion
    I am experimenting a little with my LLT sonotubes, and tried laying them on their sides. So for the first time I've gotten a good look at the drivers while they are working. Did measurement sweeps today, and some pink noise. I was curious as to how much movement I got when pushing the tubes a...

    Hi Guys, Not sure if this is the correct forum to be posting this. So I was having this discussion concerning efficiency and sensitivity and some of the guys were lumping the terms together as if they were exchangeable. The one EE I discussed this with said both terms vary in the same way and...

    Anyone have suggestions on build plans for bookshelves that have very decent SPL for their size? I already have a sub (with more on the way). I'm more interested in SPL than SQ. It would be nice to keep the price around $300 or less per speaker.
  8. DIY Subwoofers - General Discussion
    I will like to compare the efficiency of the same sub in two different enclosures. Lets say you have a AE AV15X driver in a sealed 4cf box and then decide to use the same driver in a 8cf PR/ported box. Lets say you are using 1,300 watts to power the sub. My question is, what will be the...
  9. DIY Subwoofers - General Discussion
    It seems that xmax results in greater overall SPL volume and also lower notes. But from what I can tell efficiency is impacted in that more excursion requires more power. Can anyone clear this up?

    Hey All, haven't posted here in a while. I've been setting up the video side of things with the new Mitsu 1500 Pj. Now thanx to the massive 100" screen, my audio doesn't seem to be quite to scale as far as soundstage goes. This compulsive need to build things is really out of control ! Thanx to...

    After taking a closer look on Klipsch, I'd really like to build my own speakers with efficiency over 95db/1w, but can't find any kits or suggestions... Klipsch is really overpriced here in Norway, RF82 cost 1850 US dollars.. My goal is a speaker not (much) bigger than the rf82, but as loud and...
  13. Home Audio Acoustics
    Hi! I sat playing with the distance/frequency quarterwave calculator on realtraps.com. Thought I'd see what the effective frequency of my DIY cornertraps are. I'm thinking like this: My traps are 30cm deep from the surface to the wall at the deepest. The result is a 1/4 frequency of 287Hz...
