The original Grotto™ subwoofer used trickle down technology from MartinLogan’s flagship subwoofers to deliver clean, powerful, and articulate bass in a decor friendly design. The all new Grotto series carries on that legacy and takes it to the next level. Its subtle appearance
belies the raw performance concealed beneath its grilles. 

Grotto series subwoofers offer a unique combination of understated, minimalist styling and impressively powerful, yet articulate performance. Utilizing our largest, and most powerful Hybrid Woofer Systems to date, Grotto 12 and Grotto 15 pack an incredible feature list and massive power into a classy, room friendly design, making them an ideal choice for those looking for a high performance, high output subwoofer that won’t look out of place. 

The Hybrid Woofer System used in the Grotto series, pairs either a 12" or 15" active aluminum woofer with two equally sized, custom-designed aluminum passive radiators. This driver layout provides the massive surface area necessary to achieve the increased output and lower distortion of a ported design while maintaining the more compact sizing and tighter bass typically associated with a sealed design.

Powering the Hybrid Woofer System is the brawn of MartinLogan’s powerful Magnitude®
MT-2kW amplifier, capable of delivering up to 2000 watts of peak power (1000W RMS),
and the brains of the Ultra High Resolution Vojtko DSP Engine, a best-in-class 500MHz DSP with 64bit processing. With their high output, low distortion Hybrid Woofer Systems paired with powerful and precise amplification and processing, Grotto series subwoofers have the ideal recipe for highly detailed and powerful bass performance even in larger rooms.

Hybrid Woofer System – The Ultimate Compact Powerhouse
Utilizing state-of-the-art Klippel analysis, all Grotto Series drivers are specially engineered for massive output capability and low distortion. Grotto 12 and Grotto 15 use our largest, most powerful Hybrid Woofer Systems, pairing either dual 12" or dual 15" passive radiators with a matching 12" or 15" active woofer. This driver layout delivers the best of both worlds; the increased output and lower distortion of a ported design, and the more compact sizing and tighter bass that sealed designs are known for. To ensure quick response, high output, and solid reliability, the active woofer is made of aluminum, known for its light weight, high strength, and excellent heat dissipation, all ideal qualities for such a high power application. Our design team did not want to skimp on the quality of the passive radiators either. So even though they do not receive direct power, they too are made of aluminum to properly blend both acoustically and visually with the active driver.

Magnitude MT-2kW Amplifiers Redefine Grotto Performance
MartinLogan’s proprietary Magnitude Amplifiers unleash the full potential of the custom engineered Grotto woofers. The highly advanced Magnitude MT-2kW delivers up to 2000w Peak (1000w RMS) of low distortion power for concussive impact, and effortless musicality. This ultra efficient Class-D amplifier delivers massive power with incredible precision and control, driving Grotto 12 or Grotto 15 with nearly endless reserves of clean power even during the most demanding situations.

Advanced Vojtko DSP Engine: Elevating Subwoofer Performance
Just like their smaller siblings in the Abyss and Dynamo series, Grotto 12 and Grotto 15 subwoofers utilize the cutting-edge, ultra-high-resolution Vojtko DSP engine, named after MartinLogan’s Chief Audio Technologist. Featuring a best-in-class 500MHz DSP with 64-bit processing, the Vojtko DSP engine controls all aspects of subwoofer performance in real-time. This level of computing power enables advanced features like wireless app control, integrated wireless signal connection, and other advanced DSP functions with complete audible transparency, allowing MartinLogan engineers to fine-tune performance for maximum output and fidelity. Thanks to the computational power of this sophisticated DSP engine, Grotto subwoofers are also compatible with the award-winning Anthem Room Correction system.

Reduced Vibration, Enhanced Bass
Solid bass performance is a critical component of any audio system, and helps provide visceral impact to your entertainment. Both Grotto models feature integrated anti-vibration feet to improve bass performance by reducing floor and wall vibrations. By dramatically reducing the energy transfer between the subwoofer and the floor, unwanted room rattles and buzzes are removed, leaving tighter, cleaner bass and improved system
clarity and dynamics. As a less intrusive alternative to acoustic room treatments, the integrated anti-vibration feet can also aid in minimizing noise complaints by reducing vibration transfer into adjoining rooms. Out of the box, these robust anti-vibration feet are safe for all flooring types, and optional carpet spikes are included to further
improve performance on carpeted floors.

Fine-Tune Your Subwoofer Settings with MartinLogan's Intuitive App
By far the most convenient way to adjust a subwoofer, MartinLogan’s Subwoofer Control app for iOS and Android devices allows you to easily adjust settings such as Volume, DSP Mode, Phase, and many others right from the comfort of your seat for ultimate control and ease of tuning.

Optimize Bass Performance with Award-Winning Anthem Room Correction
Grotto subwoofers are compatible with the award-winning Anthem Room Correction system. This highly advanced software measures subwoofer performance in your room and then performs custom equalization, tuning, and calibration to achieve the highest levels of bass impact and accuracy possible for your specific installation. Requires an ARC Calibration Microphone and a PC or Mac computer (sold separately).

Great speakers For my needs. Wanted a nice full sound floor standing speaker that wasn’t harsh. Using them just for music in our fireplace room not for home theater. Not a complaint at all on their lack of lower end frequencies, I pretty much knew when I ordered them I’d be adding a sub to the mix to fill in where they leave off. Now to pick the sub 😅😂

Fast shipping and products arrived perfectly. Thank you for a good experience

The delivery was quick and the unit arrived earlier Then expected because I live on the west coast.
The Eversolo T8 is everything as advertised and reviewed. The unit took about 8 hours of use to lose the bright forward sound. I’m happy with my purchase from Sate and Sound.

I'm glad I made the choice to purchase this amplifier! I couldn't be happier and the sound is quite captivating.

I just came back from visiting my big brother out of state who has a system in the mid 5 figure mark. When I came back I was inspired to upgrade but decided to wait. But then my Sub stopped working. I saw these on sale and thought “Is it meant to be?” Of course it was. I have these paired with a NAD T-778 streaming Qobuz. So far I am really enjoying these. I am hearing old songs as if they are new again. I have been listening to music more than ever. Bass is solid and highs are crisp. A truly immersive speaker. While I wouldn’t dare say they are as good as my big brother’s setup, they are close enough to put a smile on my face. I think they are a solid option for the price range. I am very satisfied and they are still breaking in.

Absolute game changer! Love the device - terrific sound quality, intuitive interface and beautiful design!

My amplifier arrived safely and has functioned wonderfully without issue. Thank you!

Reference caliber exotic retro-futuristic LP spinner. Few rivals. Few are so flexible.

I started years ago with an Ortofon Blue and this directly replaced a Mofi Mastertracker. I have coupled the LVB250 with a Darlington MB8 phono preamp and I can finally say that I am satisfied. This cartridge is exceptional and I don't think I'll ever need anything better.

Really good service and extremely fast shipping. Also good price on receiver.

Love the power of it it really feels like the gate way into high end it sounds beautiful happy with your service.Everything was all I hoped it would be thank you

I bought the M2si integrated amplifier to drive my 2.7 magnepans. It does a very nice job of doing just that. That the amplifier is advertised as dipping gracefully or smoothly down to 2 Ohms was a primary point in the buy. Plus, Safe and Sound had a very good buy on this amplifier at $ 799.00. The build quality is very good and it has a large toroidal transformer to better handle high current and increase bass response. The preamp is full Class A and is a strong point for this Class A/B amplifier. Great buy! You can't have it all at this price though. The motorized volume knob does not have an easy viewing of where it is set as it is an inset indention without a light marker. Also, no standby power for the amp but it does have excellent heat management as the chassis has a colder side versus the hotter 2 channel amplifiers side. It is a fully discrete amplifier (wonderful, no integrated except for maybe op-amps at the preamp front). 5 year warranty, hard to beat. The amplifier has to be broken in as treble is at first very forward , but settles after a good break in period. The silver white looks very sexy and has a kind of older vibe. The M2si is British and has a brightness to it which can be toned down if you use the right speakers. Magnepans can change resistor values at the terminals or maybe even use specific DACs. No complaint about not having digital inputs at all since there are plenty of line level inputs as you can use outboards which gives you more opportunities any way. I have three different DACs into the line level inputs so all I have to do is switch out the single coax cable I want to change some of the response. I like a very well made Class A/B like this unit compared to the Class D which I have tried. Soundstage is wide and there is a lot of headroom compared to a lot of class D. If the M2si performs at 90% of what their end does like it has been said, then wow. Way to go Musical Fidelity.

I have all Arcam equipment, the sound is fantastic. The price was amazing.. MusicLife app is so/so. Great piece of equipment..

Safe and Sound is an excellent place to buy audio gear. This phono preamp is excellent, as sounds as advertised and the price was right!

Amazing to deal with and best service on the planet

So pleased with the quality as well as pretty much next day delivery. Great company

Excellent CD player. Very impressed with the quality of the open box service. Absolutely impeccable, couldn’t tell from a brand new unit. Your customer service is also tops. Thanks for great shopping experience!

Amazing sound. Perfectly pairs with the components I have. Vinyl has never sounded better.

Unit sounds great butyou can hear sound bleeding through the speakers and amp at zero volume. Also bind post so small myspade pugs either too large to accommodate. Unit turned off several times, not sure why possible connection but I could not figure out maybe due to heavy load speakers .Ssrvice and sales always fantastic!

Super quick shipment and communications! Always great experience with Safe and Sound! The T8 is amazing! Big improvement over DMP 6!

These outperform my previous speakers by a wide margin: more punch, more body, higher articulation. The vocals are mesmerizing.

I was trying to scale down from a surround to a stereo setup and looking to upgrade DAC from Marantz av8805a. I have the Anthem mca 525 gen 2 amps and Sonus Faber Sonetto iii g2. It took about 70+ to burn in. It was an upgrade, but it is very subtle and hard to even notice unless really paying attention. This does fell like within the territory of diminishing returns. I don't know if it's because of my speakers, but it is the best speaker I can get given the size and weight for a small walkup apartment. However, I still decided to keep it because it is much lighter and runs cooler than the Marantz. It is also a little bit clearer (the Marantz sounded a little bit muddied, which I didn't even notice after years of using until I was comparing it with m3ai) and I noticed that it sounded louder at the same db level because of this (this means I can listen at lower db levels than I would with Marantz). I do miss the ability to fully control the Marantz via the android app. Overall a good DAC, but subtracting a little bit of points for the high price.
