Went back to work today, I have an hour commute so I finally got a chance to crank up the volume a bit. I know this is the IA forum so a bit for me might seem miniscule for some. The biggest subwoofer system I have had in a vehicle was two SA-12's with 1200 watts in an Expedition, which was great BTW. I have a stock head unit with a JL Audio FiX-82 providing the signal to my amplifiers. I was playing a notch below my clipping level using a 50 HZ test tone. I am giving the subwoofer around 550 watts. The Flatlyne sounds good. It will play every note you send it. I listen to almost every music genre and this sub sounds great. I have posted here that this sub is not terribly loud, but my ears are hurting from my drive home. You have to consider the fact that it is a 15 in a hatchback, so I would rather err on the side of being "too loud" and just being able to turn it down. I wish I had better command of the English language to describe how it just fills my car with this awesome bass that just hugs you and makes you happy. Great product plus great customer support, you just can't loose.

This is the old set up, really good subwoofer Sundown Audio SD3.

I would recommend. But look at your application and see if you can fit a 15 in there. It is a good sounding sub but not terribly loud.

When I built this system, I was thinking that I am older now and I just needed a little bass. The SD-12 was great. It was in a 1 CUFT pre-fab enclosure. There was nothing wrong with it. I needed a SQ sub that I can load into a ported enclosure so I went with the Flatlyne.

No shredder package because I am cheap lol.....build quality is top notch and the customer service is great, both from SSA and IA.

Sub sounds great, it only has about 20 minutes of play time so the suspension is quite stiff still. I am giving it about 500 watts @ 1 ohm of a DLS Audio CC-500. It plays loud and low, I listened everything from Journey to Future....sounded great!

I'll try to get it installed tomorrow.....

Sub is here! Build quality is excellent, can't find nothing wrong with it. Packaging was great.

It is like paint, but thicker. You can use a textured roller....

Thanks. It came out nice. It is pretty heavy, maybe 50 pounds. I can't wait for the Flaylyne to get here.

Box is finally done....

Rounded the edges, I'll duratex maybe tomorrow.....

Box is pretty much done.....waiting on the woofer!

I have my box modeled up, it will end up being 3.33 CUFT @ 30 Hz. My amp is a DLS Audio CC-500, HPF is set at 30Hz.

I apologize, I should have shared already. Here are both emails I got from IA: " The recommended ported box specs are 2.5 – 3.5 cubes with 12 – 16 inches of port per cube. Let me know if you need anything else." "The recommended ported box specs are 2.5 - 3.5 cubes with 12 - 16 inches of port per cube. Yes, you can use a 6" aero port if you keep the box around 3 cubes. "

I am pretty excited, I was looking at the features of the sub, under hung neo motor, full copper shorting, it is going to be great!

Tricia Wright from Incriminator Audio got me all the info. Pulled the trigger on the 15, thanks!

I am seriously considering a Flatlyne 15, I have been inputting the T/S specs in numerous box building programs and I am coming up with wacky results. I was wondering if you can recommend an optimal box size and if a 6 inch round port will be sufficient to keep the port velocities down to under 30 m/s with around 800 rms. Thanks.
