I changed my subwoofer once again :-D

Hey Everyone - Hope you're well

It's been a while since I logged onto this site and I'm sorry for the delay in responding to some of your messages (wasn't aware).

This was my previous post - https://www.hifivision.com/threads/...dayton-audio-bass-shakers.98043/#post-1078734

Got another subgrade itch sometime in July and I decided that I wanted to change the sealed 21" custom sub to a ported one. Got on the phone with Albin again and he changed the sealed enclosure to a ported one -

It's port tuned at 28hz and for me personally, I like how it sounds better now

Since it doesn't go that low, the bass shakers do an amazing job of complimenting it. Instead of driving it with the Crown XLS 2502 like I used to, I got a Fosi amp to do that job - https://www.amazon.in/dp/B07L6FN97Z?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1

Oh and I sold the Tonewinner D4000 sub because I didn't need it anymore.

Oh and if you ever plan on building a big sub like this one (it's bigger than my 10kg IFB Front Load Washing Machine), please put handles and wheels to it. I didn't do that for the sealed one and handling that was a nightmare!

How do I test my newly purchased subwoofer? How do I know it's hitting as hard as it is supposed to be hitting?

You'll need to get a UMIK-1 calibration mic and measure it with REW. I tried wrapping my head around it but it was too much for me. You can take help from the good folks on here or Chatgpt can help you.
