Hey guys. As a preface: patience is a virtue with responses here. My knowledge of DIY speakers is essentially zero. After going back and fourth between buying an ID sub to replace my lackluster Polk 505 and building my own, I decided to take the more cost effective and fun route and build my own. I need to pressurize a big room. Roughly 15x15x10, but open to kitchen and dining room. There seems to be a lot of love for this driver, so I'm planning on using Infinity 1260's and going to go off of Jinjuku's dual-opposed design, with an iNuke. My first question, is an iNuke 1000DSP enough or do you need the 3000 for headroom? Is there a most cost-effective option? http://forums.audioholics.com/forum...es/78575-modeled-infinty-reference-1260w.html This is what I need to order, correct?: 2x Infinity Drivers: Amazon.com: Infinity Reference 1260w 12-Inch 1200-watt High-Performance Subwoofer (Single Voice Coil): Car Electronics iNuke 1000DSP: Amazon.com: Behringer NU1000DSP iNuke Power Amplifier: Musical Instruments Or iNuke 3000DSP: Amazon.com: Behringer NU3000DSP iNuke Ultra-Lightweight, High-Density 3000-Watt Power Amplifier with DSP Control and USB Interface: Musical Instruments Cables: AVR to Amp: Amazon.com: C2G / Cables to Go 40047 M/M Pro-Audio Cable (6 Feet, Black): Musical Instruments Amp to Speakers: Amazon.com: Pyle-Pro PPSS30 30' Foot Professional Speaker Cable Male Compatible With Speakon Connector to Male Compatible With Speakon Connector: Musical Instruments Terminal cups (any recommendations for nice terminal cups here?) http://www.amazon.com/Recessed-Bana...qid=1355702134&sr=1-14&keywords=terminal+cups General questions: 1) Is there any reason to make this a ported enclosure? What would be the impact on SQ? If so, would you need two ports, or does that just not make sense? 2) For building the box, ply vs. mdf vs. birch? Is the ply used anything special? Could I go to home depot and pick up 3/4s ply and be in good shape, or is this something I need to get at a specialty lumber shop? 3) Does the placement of bracing have an impact on SQ, assuming it is braced sufficiently? 4) Do you need any rockwool internally? If so, how much? 5) If I went with the iNuke 3000, does that single amp have enough juice to power two of these subs? For ~$150 in drivers and materials, I would be tempted to build another sub in a year or two, and the amp is clearly the most expensive part of this build. Thanks guys! Pretty excited about this, I have a feeling it will make my (now sold) polk sound like the woofer on my towers.
