    Open Baffle

    The woofer drivers for a dynamic (i.e., cone, not planar/electrostatic) open baffle speaker need to have very large excursion capabilities, to handle the required EQ and to push the quantities of air needed for decent bass. The baffle dimensions are quite critical too. And they need to be...

    So, who's going to see DaVinci Code?

    No. I learned everything I need to know about fictional early Christianity from "The Life of Brian". :D

    The WEIRDEST 2.0 setup I've ever seen!

    And how does all that glassware stay put??

    Ceiling, soffits, and symmetry?

    Even without suspending the ceiling there's plenty of space between the joists for insulation; that's been the plan. That will give me about a 7' - 6" height. Dig out the basement!?! Oy!! The "soft" soffit ideas (insulation + cloth) would not give soundproofing, alas. That's a major...

    Ceiling, soffits, and symmetry?

    That was quick! But no, don't have the space. Well, I suppose I could if I really wanted to because I'm kinda short. ;) But I'd rather not.

    Ceiling, soffits, and symmetry?

    The area of my basement where I plan to build my HT room has a main HVAC duct running lengthwise a few feet off center. I'll enclose it in a soffit of course. My question is: is it acoustically necessary to make another soffit to make the ceiling symmetrical? Or is it a fairly minor problem if I...

    Verbatim CD-R deal at Big Lots!

    Big Lots has Verbatim "Vinyl" CD-Rs, 5 packs in full sized jewel cases for $1.99 a pack! They are printed to look like 45 rpm records but besides that gimmick the main thing is they are the high quality dark blue "azo" dye recording surface that reputedly lasts longer than the silver ones. I...

    DIY travel speakers

    While we have a few DIYers here (including me), I'm not sure many of us (including me) are that advanced/hardcore. You might try the Madisound speaker building forum (madisound.com), DIYAudio and other DIY oriented forums. By "travel speakers" do you mean something more than the usual MP3...

    Change of plans...

    Since this is a school project with a tight deadline, I suggest you proceed in that spirit and accept that the initial results will be less than optimal. In other words, approach this as a learning project for now rather than as finished speakers for your system. Even a pro cannot design a fully...

    Change of plans...

    I think you'd only need one crossover per pair, wouldn't you? The Behringer crossover I mentioned is a stereo two-way or mono three way unit. And I think it also has a sub out. If not, another of their models does.

    Change of plans...

    The Advents were excellent speakers in their day (I owned a pair of the original Large Advents for about 30 years) but progress has been made since then. It is entirely possible to surpass them with a good DIY speaker using good drivers. I hope you have given up on designing your own...

    The Seas 27TDC or 27TDFC tweeters are a bargain (I think a bit more than $30 but less than $50) from what I've read. They measure nearly as well as the very expensive and superb Seas Millenium tweeters. I have not tried them, though. I built some speakers a couple of years ago with the Vifa...

    V for Vendetta

    I loved it. However, I generally find action movies shallow and tiresome. Unlike most action flix this one had brains. It's the story that grabbed me -- and even my wife, who has even less regard for action movies. We saw it in an IMAX theatre. I don't think the IMAX treatment did anything...

    Your favorite Brew?

    Never liked beer. Prefer hard cider (like Green Mountain). A taste I acquired visiting the UK. Bourbon (Maker's Mark). A good red Zinfandel, especially with tomato-y southern Italian food. Salut!

    Building a Windows Media Center 2005 PC - Parts 1 & 2

    I was going to ask "what about us Mac users" but Awesomebass pretty well answered it for me. I have been kicking around the idea of eventually going the HTPC route but since nearly everything I read was about Wintel I didn't know if it was even feasible for Macs. Forget who said it earlier...

    Non-parallel walls?

    Right. From all I've read it has little effect except to move the locations of the resonances around in unpredictable ways. Not worth the trouble. And it'll really p*** off your builder! Stick with right angles and to tried and true methods of low frequency absorption: resilient mounting for...

    Orion progress

    I've seen that one too but, nope, that's not the one I was talking about. It uses cone drivers -- SEAS Milleniums like the Orions.

    Orion progress

    Jax is right. And since an open box with its needed EQ nearly guarantees the need for a fully active bi- or tri-amped system there's the market resistance to active speakers to consider. However, I think the old Carver Amazing speakers were open baffle and passsive. But the woofer drivers...
