Axiom Home Page Forums General Discussion Stereo Active LFRs and room treatment question

Just block the speaker off the wall to suit your build depth. You are thinking a 2D skyline. Didnt do one of those. More of a ceiling thing.

I used EPS for my Arqen fractal upstairs. Built a hot wire foam cutter and worked well. Pretty accurate cuts and was a fun project.

For the Big QRD downstairs I used 1/8” wall panelling cut into strips for well dividers and 3” wide rigid packing foam. It is over 6’ wide and 48” tall or so.

Gotta be a rigid product whatever you use. The arqen is way lighter than a true QRD. Sections can be held in place with 3M command strips… but not a true diffuser like a QRD.

Here's an interesting DIY QRD build concept ... might add a bit of weight but it reduces depth allowing one to diffuse lower frequencies ... Folded Well QRD

on blocking out the center ... it might still need space around it but it does not have ports so ... have to ask Axiom about that.

Do yourself a solid and don't ever listen to the virtual centre the active LFRs holographize during a movie. You may then want to move to the LFR 180.

Have you tried the LFR180 Mojo?

BTW I listened quite a bit to the ALFR with a virtual center … that’s how I determined that it was not going to work for my space.
It’s fantastic if you never plan to have more then two possible 3 people if you sit close.

I’ll try it again when I get the seating in but I fully expect to end up with a 180ow behind the screen.

I agree with you.

Never tried it. One fellow came on the board and raved about it. He bought 100 grand of gear. A 1500 for each set of drivers in each of his actives.

Bet he never uses more than a 10th of that …

Be interesting to ask what voltage each input of the active speaker tops out at.
That along with max power it can dissipate will tell you when you have maxed out amp wise.
Bet a 1500 per woofer and a 1250 for everything else would be close (that is if you needed more than a 1500 alone/ALFR)

Given the nature of the LFR to send sound off the backwall, i've not put any thought into adding anything for sound purposes in those locations. Am close to getting a diffuser for the side wall opposite our curtained wall though (an acoustic felt product). Hopefully will have time to finally tune all the system in and measure it in the coming weeks, though a channel in our Axiom amp went dead so i have to get that resolved.

Some neat QRD ideas
