I purchased and built a tri12apr15 kit from CSS a few months ago, built the cabinet to specs, and finished it piano black. I have been having issues with the driver bottoming on low lfe scenes in movies, and have been working with Bob through emails the past week or so. I figured I would start a...

I do realize that these are two completely different designs and will produce different results, but, what I am asking is,rather, how would these two completed subwoofers sound in comparison to each other? Here are the two different enclosures that I am considering: 1. Going with an SSD-18 in a...

My buddy and I are building a theater and planned on using the TRIO12. However it has just been designated End-of-Life. I received an email from CSS and they said they'll be bringing out the SDX12 in early December. So I'm wondering what a comparable unit would be. Any suggestions? Wait for...

Hi! Since this is my first ever subwoofer build i would like to share some pictures of the project and of course some final test results and comments about it when its all finished.

I made my first sub about this time two years ago with a TRIO12 and a Bash 300 amp. It was a pretty big ported sub and sounded great for a year or two until it got water damaged and the box pulled apart. Since then I have decided that it is much more practical for me to build a sealed, partly...

Hey guys, New to the forum, it's impressive the amount of information viewable on this site. I've managed to get a trio12 and a piece of sonotube with port from another member. I bought a pa500 amp from css. I've been told I should ask for some help on here about dimensions for this build...

Does anyone know or could speculate how two of the TRIO12 APR15 BASH500 Sub kits would compare to a single HSU VTF-15? Thanks.

Situation: I want to replace my current subs with a pair based on the Trio12 driver. The room is about 2500ft^3. The stairwell leading upstairs is on the back wall and is open, so the "real" volume would be greater than what I indicated. The footprint of each sub will be limited to 18” x 20” –...

CSS Quartet12 (TRIO12) H in 24" Cube Hi all. First woodworking project is a DIY subwoofer from Creative Sound Solutions. The kit is the CSS QUARTET12(TRIO12)H, which is a TRIO 12" woofer and 2 opposing 12" passive radiators, powered by a SPA500 Amp. The cabinet used is a 24" cube vice the...

Thanks for Mike P for his assistance in this project. I'm building a sub for an acquaintance to use in his research of the effect on subsonic frequencies on humans. I'm making a 24" (od) cube with inner 3/4" shell of mdf and outer 3/4" of Baltic Birch plywood. Yes, it will be heavy and he...

No, I didn't actually build it in the attic. But that's where I installed it. Lurked around for quite some time before finding the TRIO12 HORN KIT on the CSS website. I was immediately excited as it met all my criteria: - LOTS of output - Low response for HT - No need for additional HPF, no...

This is my first attempt at a DIY subwoofer build. I chose the CSS TRIO12 based on cost and positive reviews. I also liked the idea of the sonotube taking up less floor space. Specs: Diameter 16" Volume 4.697 ft^3 Tuning 20.50 Hz Port Size 6" Amp 500 watt Bash EQ 18.7hz...

I've been following some of the sub-woofer horn threads here and have been quite fascinated by the results. I recently came across CSS's new TRIO12 Bass Horn Kit* and have been wondering if anyone has built it yet what their impressions are. On the chance that someone has... I have a few...

So I've build 1 of 2 Trio12 subs in 4.5cf enclosures tuned to 19hz with a Bash 500w amp. Dimensions are 13widex24.5tallx36deep, it'll be placed beside the sofa so it'll be partially hidden. This is my first box build and had minimal tools, so its ugly as sin....but sounds pretty good. In the...

I am well on my way to my first sub build, and here are some quick picks I took of my progress. This sub has a tuning frequency of 21 Hz, and the inside net volume of the box including the woofer, bracing, and etc. is very close to 4.4 cubic feet. I actually made my box fit the slot port...

Hello - my first post to this forum which I've recently been reading. You all have a great resource here! That being said - I am in the early stages of planning my Audio setup after remodeling my house. I would say that for me I'm more interested in musical reproduction - than I am...

Good evening , I want to build a sub and was looking at the css kit. I would like to hear your opinion about this kit. Would you recommended it? Or would you recommended something else ? Mu budget is between $350 and $700 Alain

I decided to go with tall slender cabinets for my subs. That's what will fit best in my room. The CSS kits are cubes so I want to make them taller and narrower. Since these will be placed in a corner can I mount the driver on the bottom and the passives on adjacent sides instead of opposite...

I see CSS is currently out of APR12's so they are offering a TRIO12 kit with 1 APR 15. The recommended enclosure is still the 20" cube but they suggest mounting the trio12 driver facing the floor with the APR facing front. I was just wondering the why and what the science was behind it. Also...
