OK This was an exhilarating CEDIA 2016 for fans of Monoprice. The company originally known for its affordable cables continues to expand its catalog of aggressively priced AV offerings with the introduction of several new amps in the Monoprice Monolith line. Additionally, I spotted a subwoofer at the show that should be of immense interest to AVS Forum bassaholics.Actually, let's start with the sub. It's hard to ignore the 15" driver that's stamped with the TC Sounds logo. For those in the know, TC sounds made some of the most-revered subwoofer drivers, the LMS series, that were a favorite of AVS Forum DIYers seeking maximum performance.The sub seen at the show was a prototype and therefore did not yet have a price attached to it. However, since it's a Monoprice product, there's a good chance it's price/performance ratio will be quite high.Take one look at the sub and you know it means business. Glance at the specs and you'll understand why the fine folks from Monoprice almost knocked their booth down when they turned it up. We're talking about 1200 watts of amplification pushing a 15-inch LMS-R driver to produce a CEA 2010 max burst output of 122 dB at 20 Hz, measured from 2 meters. If that number proves to be accurate with production models, that's a completely absurd (indeed, practically unprecedented) amount of bass.I'll follow up with a separate article about this subwoofer when more information becomes available, such as pricing and availability.Now, let's get to the amps. Monoprice introduced the Monolith line at CES 2016 with the Monolith 7 ($1500), a seven-channel amplifier that I reviewed here. At CEDIA 2016, the company has fleshed out the line by adding the Monolith 2, 3, and 5 amplifiers to the lineup.As hinted by the model names, the Monolith 2 ($1000) offers two channels of 200-watt (into 8 ohms) of amplification, the 3 ($1100) has three 200-watt channels, and the 5 ($1300) has five 200-watt channels to work with.These new amplifier models will be available soon, and since they are essentially the same as the Monolith 7 (aside from the channel count), I already know that they will sound excellent.
