It started off with a phone call from Ashley with regards to a new series of DD <\/strong>that was soon to be hitting the shores of New Zealand.<\/p>\n\n\n\n

Most people know that I was the first to receive a pair of REDLINE 715 SERIES so Ashley & Lance thought I\u2019d be a good candidate to try out one of the REDLINE 800 SERIES.<\/p>\n\n\n\n

Firstly, I\u2019d like to point out that this subwoofer is the 18\u2033 in the new 800 series & is first of its range in the SOUTHERN HEMISPHERE. That on its own its insane!<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Once the package arrived I opened it up & the first thing I thought was\u2026 \u201cDAMN thats going to be heavy\u201d followed by \u201d did the boys send me the right sub??\u201d Reason I thought this is because the motor in size looks to be the same as the 99 series.<\/p>\n\n\n\n

Man its pretty impressive! Looking at the cooling set up I could see this wasn\u2019t going to get hot in a hurry. And the direct connection with more than enough cable to wire it all up. I was guaranteed that the 4\u2033 coil rated at 2krms would handle the abuse that I am known to throw at a subwoofer.<\/p>\n\n\n\n

*SPL (1 W \/ 1 m) is not an accurate indicator of a subwoofer\u2019s output capability and should not be used as a comparison to other subwoofers to determine which one is \u201clouder\u201d<\/p>\n\n\n\n

**Xmax specifications are derived via one way voice coil overhang method with no correction factors applied.<\/p>\n\n\n\n

Parameters are ran after initial suspension break in and will change over the products lifetime<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Now I\u2019m powering this subwoofer with my Atomic 5krms @ 1 ohm, 2x 100ah batteries and major part in my set up being the custom MECHMAN alternator supplied by DC-TECH.<\/p>\n\n\n\n

Through out the playing time the 818 has not once got hot or smelly. On a few occasions I have found myself \u201cturning down\u201d my bass control as the sub has progressively worn in. The 818 I found to play very clean and controlled, being designed to be played loud. Not once has it sounded out of place if you know what I mean.<\/p>\n\n\n\n

Having to compare the 700 series to the 800 series, I soon heard a massive difference between them. While 700\u2019s were loud, the 800 had just sounded so much stronger, cleaner and far more brutal.<\/p>\n\n\n\n

Being  \u201ckind on your budget\u201d this sub makes it a sensible buy aswell as being easier on your pocket for those DD<\/strong> fanatics out there.<\/p>\n\n\n\n

BUILD QUALITY: *****<\/p>\n\n\n\n

VERSATILITY: **** 1\/2<\/p>\n\n\n\n

SOUND QUALITY: **** 1\/2<\/p>\n\n\n\n

VALUE FOR MONEY: **** 1\/2<\/p>\n\n\n\n

PROS: 4\u2033 US Made coil, excellent cooling system, doesn\u2019t look like a budget subwoofer.<\/p>\n\n\n\n

CONS: 1 is never enough.<\/p>\n\n\n\n
