    Emerald Physics 4.7 makeover

    Here, sharing my positive experience modifying Emerald Physics EP4.7 speakers! Compression drivers: removed bug screens (not needed because of dust caps). Measurable improvement in 10-20K distortion (2-3 dB less), more 'silky' sound, does not really increase SPL. Dynamat on the back. Woofers...

    DIY Open Baffle Speakers -

    Just thought I’d post a couple pictures of the open baffle speaks I’m working on. Drivers were just mounted, still have to wire ‘em up. I’ll be testing with the Cerwin Vega crossovers I have just as low-pass filters for the 12” woofers. The Dayton “point source” 8” full-range drivers will be...

    Need help with DIY open baffle speakers using console drivers

    Hello everyone, I plan on making some DIY open baffle speakers using some drivers I pulled from a GE stereo console. My biggest question is what is a desirable baffle width and height to have for the 12" CTS 933C675-4 drivers? My other question is mid-range and tweeter placement? Please see the...

    Using ASC Tube SuperTraps behind OB speakers ?

    Hi there, I've been using ASC Tube SuperTraps (12", with reflective front) behind my KEF Cantatas (two tubes at about 1/4-1/3 on the front wall) with great success on improving the soundstage. Now that I got my first OB speakers (Emerald Physics EP 4.7), I have found removing absorption...

    Chronicling my journey into low power and open baffle

    This will be an ongoing thread, chronicling my journey into lower wattage amps and open baffle speakers. It may split off into just one of those if the other doesn’t catch my fancy. I recently measured the output of my amps at my typical listening level and realized that I was using...

    Please recommend a full range driver.

    I love the image that a stereo pair of single speakers can produce. Who makes the best "full range" drivers? Which is the best "bang fer da buck"? Do I need to build a band pass crossover for them? Do they "need" a baffle?

    Hanging Open Baffle Speaker

    I can't seem to find very much information on the web about Open Baffle speakers being hung from the ceiling and was wondering if anybody here has any experience with this practice. My space is limited, and have too much cool stuff (crap) to place another pair of speakers, and their wires, on...

    Powering two 15 inch open-baffle subs

    Hi everyone, I am seeking advice on a decent amp to power my two 15 inch open baffle Hawthorn Augie subwoofers. Ideally with a cross over so I can have stereo subs. Currently using a NAD integrated C 320BEE to drive them. Appreciate any input. Cheers

    DIY Open baffle conversion of W70 Wharfedales?

    I've posted the below in the British Audio section, so apologies for those that have seen this twice... I've got a Wharfedale 60D Mark II pair that are acoustic suspension and I've been very happy with them. Good crisp response and enough bass and clean highs. I also have a pair of very early...

    Wharfedale W70 open baffle conversion

    I've got a Wharfedale 60D Mark II pair that are acoustic suspension and I've been very happy with them. Good crisp response and enough bass and clean highs. I also have a pair of very early all alnico W70s that are ported. While these sound pretty good, with complex music having multiple bass...

    Series or parallel connection of bass drivers?

    I am planning OB speaker with two bass drivers in vertically stacked U frames with fullrange driver above on flat baffle and I have to decide if I should connect bass drivers in series or parallel. I have previously read on various forums that resistance in series with bass drivers may effect...

    My first OB project: Fast, cheap, and great-sounding!

    Some background and a word of thanks... A while back, I asked y'all for thoughts on some Magnavox console drivers. (See the thread Advice on Magnavox console speakers ... ) Everyone who responded offered something interesting and encouraging. The bottom line was these are good speakers...
