Ian,

A couple of questions regarding the active LFR.

1. Is it recommended to send the same amount of power to all 5 speaker sections or more to woofer? If not equal can the sensitivity of the sections be adjusted to match amplifier power?

2. Related to Q1 could you use say a class A amp for the tweeter and midrange, and maybe higher power Class D for the woofer sections?

3. Can you comment on basic room setup and acoustic treatments since there is rear firing drivers?

4. If there is future upgrades to the DSP section can these be updated/downloaded in the field by the customer?

5. With the software flexibility do you envision that this speaker will be upgradeable?

Thanks,

Current happy Axiom user...but thinking of major upgrade:)

Steve

Hi Steve,

The amp power ratings can be different as long as the gain is the same. All of our ADA amplifiers have a gain of 29dB.

No problem to mix amp classes, again as long as the gain is the same.

For an LFR reflections are your friend. Unless you are experiencing a particular room problem, I would recommend no added acoustical treatment.

The software can be updated from a header on the DSP board. It is possible to do an upgrade in the field but we recommend sending the DSP box to us for code updates. We can check the output this way also to ensure it has the code properly.

Thanks

Ian

The active speakers are far ahead of others' products. I hope Axiom invests in understanding how the FOC can be adjusted to suit various placements within the room. For example, most everyone places them against the back wall with a bit of room to the side-walls. That placement impacts soundstage depth for sure and maybe even width depending on room size. Wouldn't it be amazing if the DSP could adjust the curves to compensate for non-ideal placement so everyone could enjoy a 3D soundstage? Boundary gain compensation is one thing but boundary stage compensation would be so revolutionary!

Guys, I've now discovered Axiom's wood. Holy crap! All these years, I've just skirted by it. I'm going wood EVERYTHING! Geez, it's gorgeous. And those are just the photos. Wait 'till all my new gear arrives. I'll be all over it. My friends and BFF too! I really love what nature produces. And Axiom. If I could buy everything they made, I would.
