12" Flatlyne Review

Recommended Posts

Ordering process and packaging.

I posted in a topic at SSA asking if they were available in D4 coils because they only listed D2 the places I looked. Nick told me they could do D4 and to email him if I was interested. So following various threads here and other places I decided to go with the Flatlynes because I like to be different and not to many people have them. I emailed Nick(Incriminator) on the 22nd of December and got a reply within a half an hour. I sent payment 10 minutes after I got a reply and an hour after that he emailed me and told me they were added to the list. After all the holidays he emailed me on the 5 of January and told me they were going out that day and I received them on the 7th of January.

Upon receiving them I was impressed by the outside of the package, fragile tape and stickers letting the handlers know to be careful with the packages. I like the foam cushion protecting the top of the woofer and the woofer was in a plastic bag as well. The motor was sitting in a half box lined with foam to prevent it sliding around. Each woofer also came with a little care package consisting of a sticker, pamphlet showcasing their product line up and mission statement, a user manual for the woofer consisting of wiring diagrams, enclosure recommendations, and warranty info, and a disclaimer sheet explaining hearing loss and the air driven cooling used.

Build quality.

This driver is heavier then it looks, shipping weight is 30lbs and I believe that is all driver. I couldn't imagine the top assembly being more then 5lbs leaving about 25lbs for the motor. The surround on the sub feels to be really heavy duty just from the feel of it and I punched through some of the mounting holes which was a little resistive for a tiny screwdriver. The cone appears to be very rigid having a smooth feel to the back and a textured fiberglass feel on the front. The dust cap on the driver is very tasteful not flashy(which I like, not a flashy person at all). The dust cap is also very shallow not a big convex shape also referred to as boob cone. The drivers suspension is stiff only moving about a 1/4 inch when pressing firmly. The driver has stitched leads which is a nice touch and the coils all measured in spec of 2.8 per coil. The ADC is an interesting feature on their lines which raises the basket about 1/4 inch from the motor assembly. Playing the drivers free air you can really tell it works, just playing a 30Hz tone for a minute at ~75watts the motor seemed a few degrees cooler after playing. That means the coils should have stayed cooler then without it. And last the motor assembly, it is about 8 & 1/4 inch in diameter with a top plate of 1 & 1/4 inch tall, about 1 inch tall magnet, and a bottom plate that is about 3/4 of an inch. Almost forgot about the beautiful "black chrome" finish on the motor.

Thank you for taking the time to post this - very interesting, thorough, nicely delineated, and well-written as a bonus.

Barry Adamson?! I'm genuinely impressed. It's fantastic to have a music guy aboard.

are you able to port the flat lines is there a given size for them can't find it on their web site is why i ask this is why i am looking at the li series you can put it in ported boxes for what i know. this way i can use them in ported or sealed is what i thinking for the li series more then likely will be sealed just ncase i want it ported.

I didn't do any type of strict break in, played a 30hz tone free air on 75 - 100 watts for a minute or so, and a couple hours of playing in the install. My amp that is pushing them is a sundown Audio prototype rated at 1400wRMS @ 1ohm @ 12.5V.

Thank you for the compliments I tried.

HeHe Yes Barry Adamson. I loved the work he did on the Lost Highway soundtrack so naturally I investigated more into his music and like a lot of it, I also like a lot of Angelo Badalamenti's pieces also.

Yes you can port the Flatlynes. From what Nick(Incriminator) said they follow the same box requirements as the LI series.
