MPBX 300 S2 2 OHM SEALED ENCLOSURE

MPBX 300 S2 ULTRA-SHALLOW SEALED ENCLOSURE IS SPECIFICALLY OPTIMIZED TO DELIVER ALL THE MPS 300 S2 SUBWOOFER PERFORMANCES.

300 (12) MM (IN.) | 1000 W | 2 OHM

The enclosure structure features incomparable robustness thanks to 15 mm (0.59 in.) wood thickness. Internal sound-absorbing material virtually increases the box's volume and reduces acoustic resonances. Panel-to-panel internal bracing with solid corners minimizes resonances and round corners ease the placement.  2S² (2 Sides/2 Sounds) design provides the ability to choose between Down-Firing mounting, through supplied feet with Hook-and-loop inserts, to increase the low-frequency extension, and Up-Firing installation to obtain more punch and definition. SSP (Sub Smart Plug) features both Plug-&-Play terminal block and traditional push terminals providing bulletproof connection and quick release.

AIR 

500 W continuous power handling is an incredible result for such a compact subwoofer. To accomplish this ambitious goal, the Hertz R&D has developed the proprietary AIR (Air Intercooling Revolution) technology, optimizing the fluid dynamics of the inner acoustic structure and the magnetic group to minimize the internal compression of air and maximize cooling capacity. The 6 layers, 1.5 in. (38 mm) voice-coil with cooling openings on the former contributes to the thermal stability of the subwoofer, making MPS subs ready to face to most demanding high-spl listening session.

Large is a little big for Bostons
Color: Dogwood (Brown), Size: Large (Pack of 1)
Seems to be durable for 2 VERY agressive chewer Boston Terriers. Cricket and Alice are shockingly good at chewing - grateful they pick to do so with thier toys. Trial vs other name brand competitor. PetStages' is a little larger so harder to bite on fir small dogs, but seems to be equally durable. While PetStages proudly states it has real wood fiber and scent (whoch I thought would win)... they prefered the other. Both dogs love to chew on real sticks. But, when the bossy one indicated she was taking over the stick the other dog had, they exchanged, and kept chewing, over and over, back and forth. I mean to say, whatever the prefered stick was at first didnt seem to matter later. These super hard chew toys do make me nervous. One dog broke a tooth last summer on a different brand toy, a very expensive extraction bill, and poor pup's terrible discomfort... but the other did not and has amazing white teeth, all around.... so.

The best chew ever for a strong chewer
Color: Dogwood (Brown), Size: Large (Pack of 1)
We have a 77lb goldendoodle who loves these. We’re lucky because he doesn’t chew on anything other than his toys, but when he starts on this…he really goes at it. It’s healthy, (not synthetic), doesn’t break apart, (no pieces to worry about him swallowing), it just perfect for him. The noise may get on your nerves but it’s a small price to pay to keep him from chewing on your furniture, shoes, or anything else a mischievous dog can find.

Little pieces break off
Color: Dogwood (Brown), Size: Large (Pack of 1)
My dog is obsessed with this. It does last a long time even given her strong chewing capabilities. I wish it was a little bigger. The main reason I rated it so low is when my dog is chewing on this it breaks off a little plastic peice and sometimes it hits the back of her throat making her cough so you have to supervise with this.

Great for aggressive chewers
Color: Dogwood (Brown), Size: Large (Pack of 1)
My dog is an aggressive chewer so they are great for her. I would love to have one a bit thinner so it could fit in a holder so it is easier for her to hold while eating. This keeps her busy and is long lasting. I have purchased these multiple times.
