  1. Ported Subwoofer Build Projects
    Hello, I apologize in advance because English is not my original languange (still studying it). I need your advise if this design will fly and what corrections do I need to do. I'm changing my HT to a different room and I only have a small space for my subwoofer on the rear corner of the room...
  2. Ported Subwoofer Build Projects
    I just convinced my buddy to buy a couple Stereo Integrity D4 HT18s to complement the speakers he's getting installed in his basement. I was thinking that a good candidate for powering these would be an iNuke3000DSP. He's got time to order an amp, but with FREE shipping on the already...

    Someone must have one lying around when they upgraded (or are currently wanting to upgrade) to the 18 inch version.
  4. Sealed Subwoofer Build Projects
    I jumped on the closeout deal for the Stereo Integrity 18", it was too good of a deal to pass up. I am going to use a D4 and an inuke NU3000DSP to implement a Linkwitz Transform (LT) to reach down low. The box is being aimed for 4cuft net, which will put it near Qtc of 0.7. Some fill will be...
  5. Sealed Subwoofer Build Projects
    All, Bought one of the Stereo Integrity 15 D4 during the pre-order. I am finally getting the time to build it. It will be going in a 3cu.ft. sealed box. Originally, I had a local Behringer EP2500 for a great price that I was going to buy, but that deal fell through. So, I am now looking for...
  6. Ported Subwoofer Build Projects
    I'm planning a sonosub build for my Hauptwerk virtual pipe organ, one 18" driver in 24" tube. I decided to wait a bit before purchasing the Stereo Integrity drivers until I see how others make out with them. I had hoped to purchase one or two of the HT 18 D2 drivers here soon, but now Nick of...
  7. Sealed Subwoofer Build Projects
    I may as well join the SI HT18 build party... as it seems we got about fifty-eleven build projects going on with them right now. I would expect no less at their bargain pricing. Nothing fancy here... just a pair of 18's in a sealed box (approx. 11ft³ per enclosure). Graham (gperkins_1973)...

    Alright this is my first ported enclosure that I've ever made so I'm a big noob in that aspect. I bought two of these subs last night since eD has them on clearance. So I've got LOTS of questions here :bigsmile: I'm not really looking to experiment here. I'd like to use a tried and true nice...

    So I ordered the ED subs. What should I do with them? Box size is not a factor, building them might be (for pvc ports). I've made 3 slot ported boxes for car audio before but have not worked with PVC. It'll be powered with 500w/ each. I was thinking to down fire them in a 6^3ft sealed box (6...

    What are the criteria for choosing between the dual 2 ohm and dual 4 ohm versions of the RL-P15's? The numbers are different on the drivers, but are those numbers representative of all circuit config of the voice coils? Or, do they represent the coils wired in series, for 4 ohm and 8 ohm...

    Hello All. I am about to purchase an RL-P18 for my home theatre.:jump: Will the SQ on the D4 be any better then the D2? Either way, I plan to wire in series. My amp: QSC PLx 1602 -BRIDGED 8 ohms - 1100W, or 4 ohms - 1600W Box – Sealed 4.5 ft3. I have little feel for what 1100W will...

    Hello all. I am trying to figure out the diameter and height of the Sonotube and the length of the 6 inch port but I have no speaker software. Steve modeled it for someone that had the D2. This will be for HT only and I would like it to go down as low as possible. I have no test equipment so...
