  • Large Monster Stereo Speakers. What's the largest you've built?

    As I'm sitting here at work with nothing to do due to the weather, I got cruising the world wide web and ran across the Infinity IRS V. What an awesome looking setup! Then I got thinking: How hard would it be to build 4 separate cabinets, one containing six 12 inch woofers reaching down to 16 Hz, and the other holding like 30 tweets and 16 or so midrange to get all the way up to 40 KHz. Could it be that difficult? I know there'd be a significant investment, but why not? The Servo is the only part I don't understand, but no problem Tri_amping.
    We recently bought a farm and I have a large pole barn to do with whatever I please. The new man cave is leaving the confines of the house living room, and will be whatever I decide to build in the barn. This leaves lots of possibilities and and offers a place for something as large as these IRS V speakers. So what's the largest, closest thing to being at the show speakers anyone has built? Please chime in.

      Tom, how did three tweeters workout? I have seen this done before and have always wondered about it.

        It worked pretty well, but I had a pretty large living room back then so I didn't notice any comb filtering issues. There were actually four tweets and four mid woofers , one pair was facing rear out of phase. The bottom two subs were plate amp powered. Cadence solobaric car subs, they sounded as big as they looked. I didn't really know what I was doing back then, though, and I had no measurement tools either, but I loved them, And yes I was single at the time. 😀

          The biggest that I've ever built, however they remain unfinished. 4 cubic feet.

            This is the biggest I've ever been associated with building. 450 pounds each cabinet, 15" woofer, 8" midrange, 2" upper mid and large ribbon tweeter. The 15" woofer is in a 7 cubic foot tapered transmission line. It's a little over 5' tall.

            I don't have a picture handy, but we did build a 17 cubic foot tapered transmission line sub that hosted a 21" B&C subwoofer.

              18" subwoofer, ported, sonosub. 7-foot tall X 24" diameter. House shaker. Not stereo, but a great addition to any stereo/surround sound setup.

                    ​Pete, do you remember what species of veneer was used on that cab, it is stunning. I recall the 21" sub build with your head sticking out of the woofer opening.
