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”.

Holy shit an actual review, thank god. Yeah, I’m not getting any helpful info from phone cam videos of peoples cars rattling to pieces.

Bricksmama says:

Nice video. So tired of random, horrible noise “reviews.”

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?

TheFresh Kivis says:

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:

hi what’s your recommended box dimensions and specs for two of these pioneers
