Hi all, thanks for taking the time to read . . . BACKGROUND... A few years ago now i was wanting to build a DIY HT sub, i ended up picking up 2x JL Audio 12W3v2s (D2). i built a sealed enclosure and used an old JAMO plate amp to power it. in my old house it worked really well, the...

I have one diy 18" and I'm working on building a second matching one. The one that is completed already has a Dayton spa1000 mounted. I have someone who wants to trade a crown cl4 (1200wx2 In to 4 ohms) for a Fi driver I am trying to sell. I'm just wondering how a pro amp like that would compare...

Hey Guys, 2nd DIY sub build, 1st was a DIY Rythmik 12'' in 2007 I have (2) brand new MFW15 drivers that I was saving for (2) LilMike f20's, but since my Theater room hasn't started, I figured I'd make use of these in my 1300ft^3 room, tucked inside a pair of Marty Micros- 3.75ft^3 net.....IOW...

Hello, folks! I have been lurking here for a little while, and watching all of the amazing stuff going down, I thought I would like a piece of that action. Basically, I am trying to build 2 big honking subwoofers. (The rest of my system is satisfactory for me, but my powered Klipsch 12 just...

Hi Guys, For those who have gone down the multi sub route, have you experienced the same jump in performance going to 4 subs from 2 subs as going from 1 sub to 2 subs? Up until now I have been bent on getting 2x SB13U, but playing around with REW room sim. I see that it might be advantageous...

I purchased two Sundown SA-8's for my car. I wanted to play around with them in my HT for a bit since my car build is a ways off. Here is one next to a soda can.

I have killed one of my SDX15 again. This would be the 3rd time, so I have realized that I cannot run ported subs for my HT because I am asking for too much sound - 2 15s won't do it, and their demise is either thermal or mech. So I have found 2 used LMS-Ultras from trusted guys for $1500. OR...

finally got around to finalizing the plans and making a cutsheet. dimensions are 23x23x26. i cant do long cuts so i have to do cross cuts and wasnt sure how to lay it out. http://www.delphiforfun.org/programs/cutlist.htm is the program i used and it made it so easy to lay out my cuts. ended up...

Not sure if this is the correct section to post this but iv just bought a Crown XTI 4000 to power a couple of stereo subwoofers in my system. I would like to connect the Crown to a Naim NDX as its source. The Naim OUTPUT has only two options 2xRCA or 1 x Din. I am using the RCAs to connect to...

Well i moved into my new house back in August. been using a Tempest-X in ~5cuFT enclosure and its done just fine. But its also very directional (sits to the right of the couch and can definitely tell the "bass" is coming from there. So the builder in me has me wanting to build new boxes and use...

Hello. Having already built 3 subs before I'm now intrigued to build one or two LLT to place behind my upcomming AT screenwall. Because of depth limitations behind the AT screenwall the sub(s) can only be around 12-14 inches deep. However they can be 8 feet tall and 2-3 feet wide. Basicly a...

Hello, I already have a pair of 12" Dayton MarkIII's sitting in the closet and am nearing a chance to build a sub. I agree with the LLT idea and use would be 98% HT with a bit of music mixed in. I have what looks like a large space approved by the wife. External dims would be best limited to...

hello, I'm building 2 subs using a CSS SDX-15. (thus 2 seperate subwoofers!). I will go with either a 120l closed design, or a [email protected] ported design (still have to decide). However, I'm currently looking into an amp that will be able to drive these babies... Pure spl is not important, it...

Dear all, this summer I will be building 2 subs for use in my HT. Driver will be the well known sdx 15. The plan is to go for an LLT, tuned at 15Hz with a volume af about 250l (give or take a few). Now I have a very stupid question: do you have to take into account the volume your port...
