The Grimm Audio LS1a Studio Monitors are Grimm Audio’s flagship monitors and are explicitly for those who want the most neutral, transparent, and detailed sound reproduction possible.
A great studio monitor requires a high degree of accuracy with untrammeled musicality. Grimm Audio cut no corners developing the LS1A studio monitors and we at Front End Audio believe that Grimm Audio is making some of the absolute best monitors money can buy for your studio. The LS1A monitors offer true transparency, reproducing your audio with accurately, with all beauty intact. At the same time, the LS1A will also reproduce any imperfections, giving you all the information that you need to make it right. These qualities make the LS1A monitors ideal for both mixing and mastering.
Because the speaker cabinet is much wider than it is deep, the small, sealed box is designed to provide an effective baffle down to around 250Hz. It’s suspended between two half cylinders that combat diffractions and function as an integral two-legged floor stand. An 8” magnesium woofer and a 1” dome tweeter divides the work between them. Despite their compact size, the floor standing speakers are clearly intended as main monitors in mastering studios and mixing rooms that have space to put free-standing speakers. The DSP controlled analog subwoofer output allows for perfect and easy integration with stereo subwoofers, for those that need high SPL performance below 40 Hz.
Housed in one of the two legs are the drive electronics, encompassing two 180W Class D power amplifiers, a 48/76-bit DSP, digital I/O, AD/DA and the same clock circuit as featured in the Grimm Audio CC1 master clock. The DSP technology in these monitors can be utilized to tune the speakers to your room!
While the LS1A Studio Monitors are amazing, if you're looking to get the absolute best Grimm Audio has to offer, check out the LS1BE Studio Monitors which feature Grimm's premium woofer, tweeter, and upgraded electronics!
The Grim Audio LS1A monitors come standard “White Lacquer” as shown in the photos. However, for an extra charge, they’re available in other color finishes such as: Black Lacquer, Caramel Bamboo veneer, and Natural Bamboo veneer.
The Grim Audio LS1A Studio Monitors ship with the standard short legs. However, there are two other options you can select from: High legs (for studio applications) or Nano (no legs, for when you want to place the speakers on your desk). If you’re interested in ordering the LS1A monitors with one of the alternative leg types, give us a call for assistance.
There are two subwoofer options available for the LS1A studio monitors: LS1s (standard subwoofer) and the SB1 (premium subwoofer with Digital Motional Feedback technology). The subwoofers are sold separately. While the subwoofers aren't a necessity, there's a great benefit to incorporating them into your system. If you have any questions or need help deciding which subwoofer will be best for you, give us a call and we’ll be happy to assist.

What We Think
The Grimm Audio LS1 Reference Studio Monitor system sounds unbelievably phenomenal. But when you add the LS1 Sub-Woofer Set to the LS1s, something even better emerges. When listening to the Grimm LS1s with the subs added, we noticed a sound that was not "effecty" - as if designed for wow-factor; as if to impress someone who truly does not know what they are listening for. Instead, we were suddenly immersed inside a world of music in a way that we have not been before. Using Dire Straits' 'Water Of Love' as a reference (Listen to something you know!) we were able to hear each drum in space. It was if we could reach out and touch each tom-tom of the drum kit. It became blatantly obvious just how valuable these monitors with the subs would be not only in a mastering situation, but we think 'especially' in a mixing application. Why not get it all right from the start? Granted, we're talking about a set of monitors that with the subs, would set one back more than what they have in their vehicle. Still, for the discriminating professional, the Grimm Audio LS1 and Subwoofer Set should warrant serious consideration. We could tell right away that not only could we hear everything perfectly in such a way that we could detect any imperfection and immediately know just what to do with it, that we would enjoy our work in the studio so much more than normal. And if we would enjoy it more, then so would my clients, which is perhaps the most important consideration, after all, isn't it!?
