Product Review

I needed some 12" speakers for our practice room wedge monitors. These were affordable and I received them in 2 days. The sound quality is very good and I consider these a good "bang for the buck" speaker.

All around performer

Industry standard for this price range, well made.

At home in a bass rig, PA or guitar cabinet.

N/A

Deep bass with very good highs. I use 2 in a '68 Bassman cabinet and play bass and guitar as required.

Your general opinion of this product.

With 250 watts per speaker your covered for most any amp when used in tandum.

Great for a custom cab

So far, no complaints. It has handled everything I thrown at it. Plenty of gasket on the front.. the back has less, but no matter.

I put this into a custom built cabinet that I built. The specs for the price present an amazing value. Not too heavy weight wise, low resonant frequency, good frequency response and SPL sensitivity.

Very easy to use. I didn't have a manual of course, but Eminence has cabinet designs on their website that helped tremendously. After balancing several speakers, from basslite to Kappa, I settled on this speaker. Eminence only gives a volume of space required.. the rest is up to you.

I thought a bass speaker was only good for bass.. WRONG.. it sounds great for guitar.. doesn't require a horn for slap. My cabinet design no doubt contributes to this, but none the less.. very shocking. Everyone I've demo'd it for has been absolutely floored.

Eminence is the best hands down

Top Quality, I won't ever buy another brand ever.

250W What more could you want & I'm not electrical savvy in any way. but installing them is very simple.

The Manual was of little help but the way they are laid out when you replace a speaker it's self explanatory what goes where. It took me 1/2 Hour to swap out all 4 of my speakers.

I custom modified my Marshall 1960A Lead cab with these speakers. The vintage 30's were ok but if your playing down tuned guitars or like me 7-string or 8-string Guitars through a POD XT pro Rack Mount with a 500 watt Power amp, your golden, amazing bottom end, very tight sounding & they never break up or crackle on you. I set my cab up for stereo, left channel, right channel & these speakers are 250w a piece, that means my Left channel handles 500w and my Right channel handles 500w, a thousand watt cab with a 500w Crown Power amp. It's a Beast that sounds better than any custom guitar cabs on the market today. I dare anyone to say different, if you are going for extreme modern heavy guitar tone, these are the speakers you need & want.
