I also think sealed subs are great for deep bass if you dont have lot of space. You'll need tons of power tho!

Blocking the ports also cuts overall output. You tend to gain a little down low but lose a lot of the output at higher volume (voltage) due to port compression and a different Fq response / efficiency. Here is my 18" subwoofer with just 1/3 of the port blocked to extend from 25Hz to 20Hz. I'll take 130dB @60Hz any day. That rips! Same story with the SVS 13" I would argue the higher port tune is going to be better in most cases with both of these subs. When you go low you really need huge box, long and large port. Its just a different subwoofer.

@tktran303 Okay, its been 4 years+, any updates

As some of you may or may not know, we needed to update some libs and packages a few years back in our API and that broke enough things that make it challenging to keep the site working. All the data can be viewed, but we cant currently add or edit anything, but with a few weeks of work I can update the code and get the site 100% functional again and when that happens I'd like to start adding some newer subwoofers. I don't know Josh's schedule but its possible I could get set up here in California and do some myself. We can also bring on someone else. Just wanted to keep you all updated. Thanks.

Sorry this took so long folks. I had to upgrade mongodb driver from v2 to v6. And nodejs needed to be bumped too. I think I'll move the code to github and make it opensource so more than 1 person can make pull requests Note: There are still some broken elements but thats all on the admin side.

anyone been in contact with josh recently? I have not been able to get a hold of him.

LOL, ya, it takes work to maintain or make money. nothing is easy, but I do want to try and limp this project along if I can.

Its not (which is good news), mongodb did an upgrade from 5 to 6 and the driver I'm using in nodejs is not working with the changes. I need to make several code changes to hook that up. the second issue is a refactor I did a while back but didnt correctly update the react UI to work with the new API so we can't create or edit any systems or drivers. Its a bit more work for figure that out, but my guess is about 3-4 days tops. I might be able to do it in this quarter.

@Ricci send me a message!

eh... need to update the mongodb driver, which is a PITA bc I really need to upgrade nodejs and react too. If you dont constantly update software, eventually it deprecates. I'll get on this

Hey folks, I think everything runs its course and since I have not been updating db.com, I have not giving much attention to the forums either. At this point, there is a ton of great discussion here. I think invision has a self hosted option, but I don't see a price for it. It might be expensive too. In any case, these forums are $30 a month and lately I don't see the value in keeping em going because we don't have a lot of activity. I don't want all the content deleted, but I'm at a point where $30 every month is getting old for me. Any thoughts? I'm also willing to transfer ownership if anyone wants to take these over.

Probably decent, the Lab 12 has great mms and BL for its size giving it a low Q so it would work well in a horn. I don't see any reason this couldn't.

Looks like a new driver, not half bad on paper. Reasonable BL, not too too high mms. Price is solid too. https://www.parts-express.com/Dayton-Audio-MX12-22-12-Max-X-High-Excursion-DVC-Subwoofer-2-Ohms-Per-Coil-295-166
