  1. Excellent work. The response looks very good. No surprises.
  2. Hello... I would start by defining a few things that will help others give you advice. Budget? Room size shape? Maximum size / dimensions available for the subs? Multiple locations available for the sub? How loud do you plan to listen? Rock concert levels or more modest typical home playback levels? What experience do you have with powerful bass systems? What is your reference for the sound you want?
  3. Sounds good Phil. Feel free to post measurements or listening impressions of your sub.
  4. Chiko, I'd suggest putting some damping in there behind the drivers. It should clean up the top end a bit and "tighten" the sound.
  5. Very cool. I'm sure that TH will move some air. What's the low corner on it?
  6. Jordy, The 21Ipal is good as well but if you ever want to run a single cab it will be hard to find an amplifier that likes the 1ohm load. If you have a good price on 4 and the impedance will work for you go ahead. The semi inductance for some of the drivers that you listed are shown on the driver testing page on the main DB website. Yes that HR input is the current "best" match at least until I can get a cab tested.
  7. Sure. All of the files are available in the first couple of posts. Welcome to the forum. 🙂
  8. My recommended driver for these is the Eminence NSW6021-6.
  9. Looks like great work Hunsbedt! Good job.
  10. Either of those woofers are excellent. The NSW is a lot cheaper here and the impedance is much easier to match amps to with a single or dual drivers. Performance wise the 21Ipal is a bit more efficient and may have a very small edge in power handling because of it but it's probably not enough to be audible. Both are absolutely top tier drivers. I own both. Either company is large enough and well established that any sort of mfg defects will be taken care of. There have been some reported issues with both drivers. It happens.
  11. I've run plenty of series or series parallel cabs too. Keep the cables as short as possible and use a heavy gauge. Keep the drivers the same model and loading. It'll be fine. There are untold amounts of cabs wired or run in series everyday. Three 4 ohm 21sw152's in parallel is probably going to be a min impedance of about 1.2 or 1.3 ohms. The SP amps will "do" it. Might be a smidge low for them but they've run 2 21 Ipal's in series. which is roughly 1.4 or 1.5 ohm.
  12. Hello Cam, To add a bit more to Kyle's post, group delay is WAY over rated when it comes to subwoofers. Lower is better make no mistake but the perception of it at low frequencies has not been shown to be very audible unless it gets very bad. Studies have shown that as frequency decreases we are more tolerant of large GD and it is much more difficult to distinguish. Personally I don't worry about it below 30Hz. 20ms at 50Hz is probably not worth worrying about. 20ms at 200Hz on the other hand should be quite audible. This is why group delay is often represented as a percentage of a cycle
  13. Hell yeah Jay. Looks awesome. Probably sounds alright too. 😏
