What size room are the MartinLogan Axis and GoldenEar Invisa SPS speakers good for?

The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:

Listening Environment* MartinLogan Axis GoldenEar Invisa SPS
Near-field Poor Are you nuts?
Small Room Poor Bad
Mid-size Room Good Poor
Large Room Good Good
Very Large Room Average Good

(* Approximate Room sizes: Small < 100sq. ft / 9 m2, Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: > 400 sq. ft / 36 m2. Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual listening experience changes depending on floor height, room shape, surface materials, listening position, speaker locations, etc.)

In the following sections, we will get into more detail in order to better understand how the MartinLogan Axis and GoldenEar Invisa SPS compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers

One of the fundamental differences between these two speakers is that Axis is a 2-way design whereas the Invisa Signature Point Source SPS is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Driver MartinLogan Axis GoldenEar Invisa SPS
Driver Setup 2-way 3-way
Tweeter 1.25x2.4-inch ----inch
Midrange - 1 x 5.25-inch
Woofer 2 x 5.25-inch 4 x 5.25-inch

Axis features a 1.25x2.4" Folded Motion Ribbon Tweeter and 2 x 5.25" Aluminum Woofer . On the other hand, the Invisa Signature Point Source SPS features a ---" Folded Ribbon Tweeter , a 5.25" Midrange and 4 x 5.25" Polypropylene Woofer .

Frequency Response

Axis has a frequency range of 45-25kHz whereas Invisa Signature Point Source SPS has a frequency range of 25-35kHz. With a minimum frequency of 25Hz, the Invisa Signature Point Source SPS can go significantly deeper on the low side and provide stronger bass compared to the Axis's min frequency of 45Hz.

Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the In-wall class in our database.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.

Impedance and Sensitivity

Axis is a 4 ohms speaker compared to the Invisa Signature Point Source SPS which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Axis can provide this impedance level.

These two speakers also have different sensitivity levels. Axis sensitivity is rated at 94 dB and the Invisa Signature Point Source SPS's is rated at 92 dB. This 2 dB difference makes the MartinLogan Axis a more sensitive speaker compared to GoldenEar Invisa SPS, hence will play louder with the same amount of watts.

Power Range

Power range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.

Axis can handle a max power of 350 watts RMS from the amp the whereas Axis has a max power handling value of 250 watts RMS , 100 watts less than the Invisa Signature Point Source SPS.

Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impedance, sensitivity and system efficiencies.

Input Type and Bi-Amping / Bi-Wiring

Axis features Spring post type posts and Invisa Signature Point Source SPS has a Spring post type posts. None of these speakers feature bi-amping/bi-wiring.

Physical Specs

Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons.
