    Comment by 'VinceHoffman' in item '"The Vinneplex"- our dual duty music & cinema room'

The acoustic treatments seen in the earliest pictured iteration of my purpose-built "stereo room" (from 1997) were entirely DIY. The sidewalls and ceiling treatment were DIY...

    How Big or Small is Your Physical Movie Collection?

    Thanks @phillihp23! It's a 4 bay 30" tall Salamander Designs Synergy series cabinet. I bought it back when we first had a toddler in the house (He is 18 now- LOL!) and I had a lot more gear to rack. Back then our first plasma-screen-based (movies and console gaming) home theater resided in the...

    How Big or Small is Your Physical Movie Collection?

    I'm a big proponent of owning the best physical media version available of your favorite movies and TV series. Despite having thoroughly culled and curated our physical media collections to get rid of titles we don't love enough to repeatedly watch or listen to, at this point our media...

    How many subwoofers are you using in your main system or home theater?

    I run four Seaton Submersive HP subwoofers in a 20x14x11 foot sealed, soundproofed, and thoroughly treated room. The four dual-opposed 15" Submersives are arranged in a distributed bass array with pairs placed at the quarter wave points along the front and rear walls. I only apply DSP EQ to the...

    All time favorite Movie Thread

    Blade Runner- the Final Cut. From the first time I saw it in my teens to the most recent viewing 40+ years later (and the dozens of viewings in between), this one never gets old for me!

    Vinyl Cleaning Methods - How do you clean your vinyl?

    After decades of using effective but deafening and labor intensive vacuum based RCMs (first Nitty Gritty, and later a VPI), during Covid I switched to Ultrasonic cleaning. I briefly owned a Kirmuss but found his cleaning regimen just as time consuming as the best practice use of the prior vacuum...

    I just texted you @Sliderule. Do you own an Apple iPhone/iPad/Macbook with which we can communicate via Facetime?

    How to find cause room response problem

    I have an even cheaper proof of concept @skid00 & @Sliderule. -Visit your local Home Depot or similar builders supply store and purchase one or the other of what I've pictured below. -Keep your receipt! You'll need it later. -When you get home DO NOT OPEN THE PACKAGES. Simply stack the sealed...

    How to find cause room response problem

    As I previously suggested @Sliderule, reach out to Acoustic Sciences (Corporation) for some good advice and a possible solution. Art Noxon, ASC's founder built the very first Tube Trap prototypes with the specific intent to absorb the back wave of full range Magneplanar dipoles way back in the...

    Uneven Frequency Response in Treated Room

    Some photos of the room as it is currently setup and acoustically treated along with a description of the gear and acoustic treatments you've employed would be very helpful @laurynasmega.

    How to find cause room response problem

    Not in this case @Mike-48. Your calculation above assumes a monopole loudspeaker design with an essentially omnidirectional radiation pattern at low frequencies. In the OP's case we are dealing with a dipole loudspeaker where its rear radiation is 180 degrees out of phase with its forward...

    How to find cause room response problem

    Hey @Sliderule how about we arrange a quick phone call (assuming you are in North America) or a Facetime chat and I'll clarify exactly why your 200Hz-ish suckout problem is that strong reflection from the wall immediately behind your speakers...
