(August 2, 2023) The power and performance offered by Monoprice's Monolith branded subwoofers is undisputed. We here at AV NIRVANA have experienced it for ourselves during past testing and review sessions, finding that Monolith delivers on its promise of uncompromised performance. And, what's better is Monolith's desire to bring that performance into your home without battering your wallet.

While the brand's subwoofer lineup carries impressive standard pricing, Monoprice's current summer sale amplifies savings by giving you up to 50% off most of its models. That means more boom and more buck for you!

Take a look Monolith's current subwoofer sale offerings and see how much you can save... It's time to level up!

The baby of the freestanding Monolith sub family is the Monolith THX Certified 8" 150-watt Powered Subwoofer equipped with an 8" driver for performance down to 24Hz. Engineered with a vented MDF enclosure, the sub's downfiring cone flawlessly reproduces low‑frequency sounds, enriching your audio with impressive depth and clarity. Its tuning is finely calibrated to ensure a seamless blend with the satellite-style speakers, resulting in a well‑balanced and immersive soundstage.

The Monolith M‑IWSUB8 8" In‑Wall Subwoofer can be mounted in your wall or ceiling to add powerful bass to your home theater experience. Outfitted with a compact, 8" polypropylene woofer, heavy-duty mounting tabs, and a paintable magnetic grille, the M‑IWSUB8 can dig down to 36Hz without taking up any floor space. Its 91dB sensitivity ensures an easy pairing with just about any amplifier.

Stepping up in size, the Monolith M-IWSUB82 Dual 8in In-Wall Subwoofer carries two 8" drivers for even more deep bass performance down to 36Hz. All you need to do is add power (recommended amplifier should output 50-watts to 300-watts RMS), and you'll have discrete playback hidden in your walls!

THX Certified Select for room sizes up to 2000 cubic feet, the Monolith M-10 V2 THX Certified Select 500 Watt Power Subwoofer's ported cabinet and 10" driver are capable of impressive output. Tapping the power of a 500W RMS Class D amplifier built around a Texas Instruments 48‑bit data path (with 28‑bit filter coefficients) and DSP engine, owners can drive their home theater experience down to 17Hz when run in a vented, Extended EQ mode. The sub can also be sealed for output down to 20Hz.

Using the same 500W RMS Class D amp found on the Monolith M-10 V2, the Monolith M-12 V2 12in THX Certified Ultra 500 Watt Powered Subwoofer increases driver size for more effortless output. Its THX Certified Ultra stamp says it's suitable for rooms up to 3000 cubic feet, with output down to 17Hz (vented) and 20Hz (ported). With a current sale price of $699, the M-12 V2 delivers insane performance for your coin.

The Monolith M-15 V2 15in THX Certified Ultra 1000 Watt Powered Subwoofer has the muscle to take your low-frequency game to a higher level. Weighing nearly 133 pounds, its triple-ported cabinet is a robust statement to LFE reproduction. And sub's 15" driver is capable of a 25cm XMAX (one way), meaning it can be driven hard! Output down to 14Hz (vented) is fueled by a 1000 watts RMS Class D amplifier.

Power built into a space-saving design is exactly what you'll get with the Monolith M-212 Dual 12in THX Certified Ultra 1000 Watt Powered Subwoofer. Equipped with dual forward-firing 12" drivers and a gnarly 1000 Watt RMS amplifier (1800 Watts Peak), the M-212 can confidently hit frequencies below the 20Hz threshold. Tested and certified by THX and receiving its Ultra status, a single M-212 can energize rooms up to 3,000 cubic feet.

Positioned as second in command on our list, the Monolith 13in THX Certified Ultra 2000-Watt Powered Subwoofer is a powerful heavy-hitter. Armed with THX's Ultra status and a beefy 2000 Watt RMS amplifier, the 13in can happily operate in most any large room setting. Owners can expect performancee down to 16Hz in vented configurations with Extended EQ engaged.

Bigger, badder, and absolutely monstrous! The Monolith M-16 THX Certified Ultra 2000 Watt Powered Subwoofer is deserving of the brand's top seat at the table. Its luxurious cabinet features a matte black painted surface, making it unique amongst its Monolith peers. And its overall size (28.1"L x 22.0" W x 25.6" H) and massive 171-pound weight say everything about its output capabilities. Sporting a 16" driver and four, yes f-o-u-r, ports, the Monolith 16in can command rooms up to 3,000 cubic feet in size. Monolith says the sub's onboard 2000 watts RMS amp can peak at 3,800 watts, with performance hitting as low as 14Hz. If you're looking for the ultimate in Monolith output, this bad-boy is a sure-shot choice.
