Product Details

Eminence Lab 12C High Power 12" Subwoofer Speaker Driver 4 Ohm

The LAB 12C, from Eminence, is a 4-ohm take on the original LAB 12 subwoofer (for more information on the LAB 12, visit the History of the LABhorn thread at ProSoundWeb). The 12C features the same long-throw construction with a heavy-duty 12-spoke die-cast aluminum frame and Kevlar® reinforced paper cone. A lower impedance voice coil is designed to handle 500W RMS, 1,000W program power, and extract even more power from your amplifier, while nickel-plated, spring-loaded speaker terminals offer quick connection. Proudly made in the U.S.A.

Eminence's LAB 12C is designed to perform optimally in a small, sealed 1 cubic foot enclosure, or a 1.25 cubic foot vented enclosure (using a 4" diameter port that is 14.75" long for a 38 Hz tuning frequency) for automotive use. When used in either application, it is recommended to use a steep 35 Hz high-pass filter.

For home theater use, Eminence recommends a 4.5 cubic foot ported enclosure using a 4" diameter port that is 14.5" long that tunes the cabinet to 28 Hz and yields an F3 of 29 Hz. When used in this manner, a steep 25 Hz high pass filter is recommended.

For even more enclosure recommendations, see the Related Items section.

Eminence Lab 12C High Power 12" Subwoofer Speaker Driver 4 Ohm
Eminence Lab 12C High Power 12" Subwoofer Speaker Driver 4 Ohm is rated 4.4 out of 5 by 5.
Rated 5 out of 5 by from Boom for the buckModified a cerwin vega je36 folded horn in about 1 hour to retrofit the 12" lab both sealed volume and obviously baffle size. It's awesome!!!Pounded and went low!!! 12" eminence lab killedThe original 18" vega in output and sound quality by a mile. Very good driver if used properly and coupled together

Rated 5 out of 5 by from High output at 30 Hz with 2 PRs in ~2 ft3 boxUsed BassBox Pro to design a 2+ cu ft box with 2 opposing Dayton passive radiators (from PE) for over 115 dB at 29 Hz. The boxes are heavily modified flat pack kits, designed for 12 inch traditional bass reflex slotted port. I am using 2 of these boxes for Hammond organ pedal bass, needing power at 32 Hz pedal C. Needed extra grill spacers to handle excursion. Powered by Crown XLS 1500 (>500 W/chan @ 4 ohms, confirmed during testing) that gives up before the Lab 12C. Measured impedance to verify design. Long experience with many drivers. Speaker is everything as advertised. Highly recommended.

Rated 2 out of 5 by from Ultra's will bottom this speaker out.I've built amps for years and was on the road as a pro musician for over 18 years. Eminence was always good to us on the big p.a.'s... The 18" would hold up better than JBL or EV. I was building a powered sub box for a friend and decided to try this 12"eminence. It would bottom out before I got it up to 200 or 300 watts. I even added a 24db crossover to shut out everything below 25 hz and it still bottomed out. Very disappointed. I bought a JL Audio 12W3V3 and you can crank it now with clean ultra lows at all volumes.

Rated 5 out of 5 by from Best kept secret for car subwoofer out there!Got 2 of these Lab 12Cs each in 1 cube sealed. Pushing 500 watts to each.They can do anything! Go low, be quick for double bass tracks, and play clean. LOUD is an understatement for these. I love how these music is accurately represented using these in a small sealed enclosure.I tried using 4 10" JL 10W1V3-2 in a sealed box since I wanted more punch than these Lab12C subs. Long story short....They sucked compared to these Lab12C Subwoofers!Building a new bow now to use 4 Lab12C subs each in a cube with an Alpine MRX-M240 amp, running at a 4 ohm load.If you want accurate bass reproduction look no further than these Lab12C Subwoofers!

Rated 5 out of 5 by from super woofer!I used these in my Intrepid 3way build. In 3cubes with 25sq in of slot port and tuned to 25Hz, they are nothing short of incredible. Though regarded as a subwoofer, I am crossing them at 300Hz with a lr2 electrical filter and they are superbly clean. The speakers debuted at InDIYana2013 and received multiple compliments on their bass response. I could not be happier with them. I routinely feed them about 600w and the amp gives up well before the speakers do.

I'm working on a street beater. I normally use subs like dc audio or DD subs for this type of project. Looking to do a 4th order bandpass with 8 lab 12s. What should the seal chamber be and ported side be and port sqin and depth. Thank you

I have a 2cu.ft. enclosure with sub and 4" aero port included tuned to 32hz.would this be okay for this sub or would the dayton ho be a better candidate?thankyou for your time.

Asked by: miked74
I would recommend the Eminence for this application, it has a smoother overall response and about 4 dB more output with the same power input.
