Pioneer TS W311D4 Audiophile Review

I put this video review up because I was sick of looking at subwoofer “reviews” where it’s just a video of the subwoofer moving a lot and making noise with no other explanation.
This is an in-depth analysis of an affordable, entry-level subwoofer, The TS-W311D4 from Pioneer.
In this video I use the box/subwoofer matching program, WINISD to analyze the frequency response of the subwoofer in sealed and ported boxes at different tunings. I also give my personal experience and point out some claims that I think are either misleading or untrue.

Music is by B-SHOC. A Christian Rapper. The song is “Hellbound”.

whats up Brian, Are these speakers free air like if you want to place them on a board and use the trunk as the box like the old pioneer impps?

Hello Brian, you made a very nice video there!! I appreciate that you’ve made a real review here 🙂 Thank you!
My problem is, that I don’t have much experience with building subs.. I’ve built like about five enclosures without any “pre-planning”.. They sound not bad – but now I’d like to build a good closed enclosure (because I’m driving an A3 8L 3 Doors and it doesn’t have much space..) + I love accurate good base
I listen to a big variety of music. From Metal to Core to Hiphop to Classical to Rap – Dubstep – Vocal..
I’d really like to get the job done good.. I’ve downloaded WINISD but I can’t find the TS W311D4 Sub in the settings + don’t really know much about all the “herz” stuff..
Brian, I’ve bought a Pioneer GM-D8604 Amp and want to use two channels for the sub and two for my new front system (..other story)
What would you recommend me? Do you have a recommendation in metric size? I have 21mm “MDF Wood” that I can use – PS: Why is the front side of your sub double?
Greetings, hope I didn’t spam you too much here 🙂 I’d be happy if you could give me a tip!
Take care

Henry Fernandez says:

That Soundstream is a good looking sub with the perfect RMS watts im looking for, so should I make that free air move? I already saved Soundstreams Cali # so I will call them monday.

Ivan Pelser says:
