I'm planning on purchasing the Dayton Audio RSS460HO-4 Reference 18" flatpack kit from Parts Express as soon as it's back in stock. I was originally keen on doing a Stereo Integrity 18" build but it seems the prices have increased and the discounted Dayton kit at $360 shipped
now looks to be a better value. The flatpack from DIY Sound Group with the SI 18" cutout also isn't available currently. No big deal, i've read many times that these drivers are neck-to-neck in terms of performance. I don't have any woodworking tools (besides a drill and clamps) so a flatpack build is my only option.
Details on my room and listening preferences…this will be placed in a small bedroom around ~1,000 cubic feet, so a very tiny listening area. The sub will be replacing a Rythmik FV12 in my bedroom's 5.1 HT setup. I actually have no desire to upgrade my Rythmik as it absolutely demolishes in this setting, but I figured I would move the FV12 to my computer desk as I listen to lots of music there. I only have room for a single box, so no plans to expand to multiple subs. My preference is split between movies, games, and music, with a slight favor towards music. I do like to listen loud sometimes.
A few questions...
1. What would be the best route when choosing a power amp for this sub? I'm aiming for value but I also want to extract all of the sub's performance and don't mind springing for a more capable amp for a few more bucks. I hear the Dayton driver can take 500-1,500 watts so i'm thinking a Behringer iNuke NU3000DSP bridged mono at 4ohms will give it sufficient juice while also taking care of EQ. I've also heard great things about the Crown XLS Drivecore amps. Crown seems to get a better rep than Behringer, although the dollar to watts ratio isn't as high. Would an XLS 1500 have the same capability as the iNuke for tuning the sub? In other words, would I still need a miniDSP if I decide to use the Crown amp?
2. Compiling a list of what I need…the woofer and cabinet -- check, power amplifier + DSP -- check, plus 5 pounds of Acousta-Stuf, speaker wire, screws, zip ties, glue, and binding posts. Am I missing something? Is a microphone like a UMIK-1 + REW software necessary to measure and tune the frequency response flat?
3. I'm trying to envision how everything is connected and i'm a little confused about the rear of the iNuke. Do the inputs/outputs accept banana plugs or bare speaker wire? Taking into account that I will be running the amp bridged and I only need to power 1 sub, how exactly do I wire the subwoofer to the amplifier and the amplifier to the receiver?
4. My current Rythmik FV12 is placed near-field and I get very impactful tactile response, which I believe is partially due to the front-port. Will switching to a sealed subwoofer significantly lessen this effect?
This is my first time building a sub and I still have much to learn. I'll be using this thread to detail my progress and to seek further guidance once I have all the parts in my possession. I also plan on digging deeper into other DIY threads to supplement my research.
Any info, links, tips, advice is appreciated!
