Monolith M-IWSUB8 8in In-Wall Subwoofer | Passive, Paintable Grille, Easy Install, Adds Powerful Bass To In Wall or In Ceiling Home Theater System

I replaced my 10 inch monoprice Alpha with this. it is 4 ohm, so loud enough using a 100 amp Audiosurce amp. It is not advertised but internally it has "thx" printed on the frame, so presumably it is thx certified (?). It i only 8" dsia. but the high quality driver still allows it to go down to 36Hz. The internal crossover can easily bypassed using an internal configuration option. ( I am already using the AVR-s crossover set at 80 hz and I did not want to stack 2 crossovers) Wall cavity preparation. such as bracing, and fstuffing goes a long way towards eliminating unwanted rattles and resonation., There is also a similar double spaker configuration, use that if you want more wattage.

Easy to install. Good punch. Heavy, quality piece. Installed my my living room in new 2.1 setup and it sounds crisp and lively. Only thing that keeps me from giving a 5 star is that the grill fits weird. Others have mentioned the same thing. The grill sticks on with magnets and is basically the same dimensions as the sub housing itself with no overhang, so you end up seeing the black lip from the sub housing. Would look cleaner if the grill was slightly wider than the housing so that it could cover it completely and sit flush with the wall.

Purchased this to replace the 10? alpha installed in an outdoor patio 5.1 system paired with 6.5? alpha series. The alpha was good but not overly accurate, distorted at higher volumes, and the grille liked to rattle. This little 8? is amazingly clear and tight at all ranges. I have had it installed for less than 2 hours and it sounds awesome. I?m sure after break in and adjustments it will only sound better. If you are torn between this and the alpha and can afford this one get it. Build quality is unbelievable the grill is far superior and the sound quality is awesome. Ive had multiple monoprice home theater setups and have always been impressed this one by far is the cleanest sound yet. I will likely be replacing my 2 12? klipsch in the house with the dual 8? Version very soon. Maybe 2 ?? For those wondering 150rms at 4ohms dimensions are now listed for cut out dimensions.
