| Great for a custom cab |
| Quality |
| Would you consider this product to be made well? How dependable? |
| 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. |
|
| Features |
| What do you consider to be the best features of this product? What features would you add to this product if you could? |
| 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. |
|
| Ease of Use |
| How easy is this product to use? How easy is the product to use with other products? Did it take long for you to learn to use this product? Was the manual helpful? How playable do you consider this product to be? |
| 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. |
|
| Sound |
| How is the tone? |
| 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. |
