Platform 5

The Platform 5 series is a huge subwoofer that should only be used by the serious competitor or enthusiast. This subwoofer is capable of extreme power handling and more output than any other subwoofer that we have ever offered. The Platform 5 is a 100 lb. behemoth built with enormous 11″ diameter triple stacked magnets and is the only subwoofer that we offer with a 4″ diameter voice coil. This subwoofer was designed to be the biggest, strongest, loudest subwoofer that we could deliver. It uses the strongest possible magnet grade and an enormous 8 layer voice coil to create an incredibly strong magnetic force capable of moving the extremely stiff suspension to huge excursion and output levels.

  1. TeamPsiBird

    Look no further than the platform 5s if you want ground pounding bass and a badass woofer. These things are monsters! I have 4 of these in a firebird and they are beasts! David does amazing work and has top notch quality and customer service. Definitely worth every penny. Don’t second guess yourself on these 100lb. giants!

  2. Charles rickard

    I have 4 of these on 24k end. no issues. David and psi are excellent at delivering nothing but the best. biggest subs I have ever ran. I will never run anything else.

  3. Justin Raatz

    Hands down beat subs you can get on the market. David and David alone builds these monsters with the beat parts you can get. I run these in my avalanche on 2 twisted sounds 8.5ks and don’t skip a beat and take awhile to warm up the coils which means no worries on over heating unlike most of the other subs on the market. If your looking for the best of the best look no further then psi platform 5 hps guaranteed to win and built to last

  4. Jovani (verified owner)

    This sub was beyond my expectations. I was a bit impatient with the build time I must admit. But after having my box built and I just installed it, I’m at a loss for words. Yes it’s currently still in the break in stage on a Soundqubed 4500.1 but this sub takes what it has to offer. I can’t wait til after the break in on the same power to see how it sounds. Thank you PSI for building this sub for me. I will be a repeat customer of this company

  5. Joshua Jarvis

    quality and durability is superior to anything else on the market. customer service is also amazing.

  6. Blade Thompson

    Absolutely can’t beat these subs I have a single 15 on 10k and it takes it like a champ and I’m talking about daily full tilt music love these subs

  7. Scott Anthony

    So I took y’all’s reviews and said f*ck it! I’ll buy 1. I ended buying 2 more. You know the best part about these subs are….. you can’t break em. I recommend if you get the 12” you absolutely must brace it. The 4-spoke cracked on mine. The 15/ 18” use a 6-Spoke. So I changed the 12” basket to a 15”. I still brace it cuz they heavy AF. I have owned literally probably every manufacturer’s top tier sub. ^ Cake. (Top of the cake)
