Eminence LAB 12 Professional 12" Subwoofer Speaker
Eminence LAB 12 Professional 12" Subwoofer Speaker is rated 4.9 out of 5 by 30.
Rated 5 out of 5 by from GREAT LOW ENDI've been running professional sound for 10+ years, these drivers loaded in a custom box are simply amazing. I've got 2 boxes with 2 LAB12 in each box, they just shake the room.

Rated 5 out of 5 by from Awesome speakerBuilt cabinet my son had designed for the youth room at church. It looked pretty small on stage, but the sound was anything but small. Solid bass is something that they didn't have before, but this sub has proven to be more that everyone had expected. Well worth the money and the time.

Rated 5 out of 5 by from Awesome SubwooferI have been using Eminence speakers since the 70's and you can never go wrong. The Lab 12 Subwoofer is great. If you want to know what subterranean feels like get it, If you want to know what a kick drum sounds like get it. I built a 1.92 cubic ft. cabinet using a Bash 500 Watt module in a bass reflex enclosure. I have been listening to this woofer for the pass 4 weeks and I'm very HAPPY. My main speakers have dual 12" Eminence woofers in them also. Eminence woofers handle lots of power and they last!!!!!

Rated 5 out of 5 by from PAL12 tapped horn subwoofer using this driverI recently designed a tapped horn using this driver. It is meant for PA, but could be useful in high output home music systems.With the correct high pass and around 500w rms, this sub kicks some serious butt, for an awesome price vs performance ratio.If you're looking for something that will do 35hz-110hz or so, and not break the bank, in a 30"x38"x15" package, look no more.More on the design here... It out!

Rated 5 out of 5 by from goodnice subwoofer, when i opened the box it looked bigger than i expected. this woofer is powerful, with the right frequency sounds i can feel my couch moving across the room. im only powering it with a 120w amplifier, and i can already tell that its not enough power for the sealed box i made.this subwoofer needs some wattage to really show off. but its a great subwoofer for the price.

Rated 5 out of 5 by from Eminence Lab 12 subs for for hifiI use two of these...each in a 2.5 cuft sealed box. One for left channel and the other for right low, both low passed at 100 hz at 12db/oct. they are powered by an QSC RMX2450. I used them to replace the dayton reference 12s. They fit right in without any extra work on the baffle cutouts. They sound terrific! Their extension is quite deep. Very musical, blend really well with the mains (high end speakers like Harbeth SLH5s, 4pi, etc) and substantially better in every way to the dayton ref 12s. Highly recommended for home hifi use.

I built 4 vented enclosures at 2.6 cuft after port displacement. Port is 13.5x1.5 and 12" deep. There doing the job I need. Was just wondering was is this can tuned to. Was hoping to get into the low 30s

Asked by: FTL music
With that volume and port size the tuning frequency is 38 Hz.

Currently just built BFM tuba 30. what crossover does PE sell that would best serve this woofer.

Asked by: jvr31
There is no such thing as one crossover for all applications. The crossover needs to be determined based on many other factors, such as how low your main speakers can play safely and what will blend the best in the room.

Which one do you think would be better Matt?

The box I have is 18x18x21 and Has 2 rear, 3 inch ports. The amp is THX cert. so the freq is 21-100hz. I dont know if this sub being 6 ohms will hurt the amp and I dont know if the Dayton rss315hfa-8 12". would be a better pick. Thank you for you help!
Asked by: mikeado
Assuming the amp will be fine with a 6 ohm load the Eminence is a much better option.

my home subwoofer is 8 ohms

I have a 300 watt powered subwoofer for my home theater. I blew the factory 12 inch boston that was in their. Will this one be better than the Dayton rss315hfa-8? and also will it work fine with only a 300 watt amp and going from 8 ohms to 6 ohms?
Asked by: mikeado
You will want to choose a subwoofer that will work the best in the enclosure you have. If you can supply dimensions for the box and whether it is ported or sealed I can help you better.

Can you tell me the difference between this sub and the Eminance 12c? Which is more suited for Automobile use?

Can you tell me the difference between this sub and the Eminance 12c? Which is more suited for Automobile use?
Asked by: Stratous0
There are a few slight differences, the 12C model has slightly higher power handling and a 4 ohm impedance load. They both will work in similar enclosure volumes. For an auto application I would recommend the 12C in about 0.8 cubic feet sealed.
