Axiom Home Page Forums General Discussion Stereo Out with the new and in with the newer

I moved the 800v4 today. Rich will be happy. My living room right above was not. I was only listening to blues at subdued volume.

Time for some more learnings.

As some of you know, I've been feeding my dual 500v4 off the active DSPs. They are positioned on the inside of each LFR. The 800v4 is in the back of my space on the .1 channel. I often switch it to what Onkyo calls "double bass" which sums the front channels and sends them to the sub. In this configuration, the 800 adds some real nice lower end support to the 500s. The 500s add spatial dimensionality to the bass.

As you can see in the top image below, I've now moved the 500s to the sides of my space, forward of my MLP. I also moved the 800 11 feet in front of me. I tried two configurations: a) 500s still fed off the DSPs and 800 off the .1 and b) all fed from .1.

Moving them to the side did what I hoped it would do - bring the sea of bass out from my front wall so that it illuminates more of the space around my side walls and into my room. This may be difficult to understand because I already had a lot of subbage. But, it has to do with how the subbage interacts with the room. I had room-filling bass to be sure that no one in their right mind would complain about. But, I suspected it could get thicker and more textured.

That it did. But not enough. I paid a lot of attention to placement and then calibration...at least as much as I could given the very humble controls and tools I have. So I then tried configuration b) and fed all three subs from .1. Bingo! The bass now is deeply saturating from the front wall to almost my MLP. The increase in texturing doesn't require an audiophile degree. It is extremely noticeable. The highly resolved growls that I love so much from my Axiom sealed subs have increased in resolution and intensity.

My dual 600s in walnut caramel arrive on Tuesday. Those are going in the back and I am keeping my fingers crossed that with both of those, I will have a temporal, spatial and spectral equipotential bass field across my entire room.

The second photo below is the splitter I am using on the 800 to feed the 500s. I don't recommend it. If you are thinking of a splitter, get a Y-cable instead.

Finally I have included links to the coax cables I purchased for the subs and joiners. I tested the conductivity and insulation for both. I didn't want any shorts that could take out my gear.

Edit: I forgot to mention I have a ton of headroom. The Onk sub gain is set to 0. The 800 is 3 on the gain dial, one 500 is at 4 and the other at 5. At my usual -30 to -20 music listening level, I likely have at least 40dB of headroom on each sub.

The 600v4 are here! The 600v4 are here!

Crank that shit up to 11 and tell us how they sound.

Here they are in all their yummy walnut caramel glory!

Axiom has added two more horizontal straps in addition to the previous two. Also the foam up top has been thickened with more layers. FedEx appears to be more careful now too based on the condition of the boxes in the last two shipments. Their drivers have been very helpful.

Here's a photo of the "lab". Some easy clean up required.

It's a whole different ball game now boys and girls. Single, large sub will do? BULLSHIDO! Mojo's dojo says differently. But I always knew that from ripple tank experiments in physics. Physics makes us all its bitches!

I love how all the equipment now doubles as a heat source. I can trade my fireplace in for more audio gear.

I am hearing articulate string bass in songs I've never heard before. Not subtle at all! Wow.

The room saturation even at low volumes is absolutely incredible. Turning it up makes an emotionally excellent experience even excellenter.

I've confirmed the 600v4 goes as low as the 800v4 in my room. They both start moving at 1 Hz but don't really get going until 10 Hz. I'd say 1 is the very useful start of the range but some may say even lower.

The HP drivers on the active LFR1100s also keep up right at 1 Hz on up.

Nothing to sneer at that's for sure.

Edit: When I turn on all 5 sealed subs, no one would argue that infrasonics down to 2 Hz are usable. No one would argue because they can feel the ripples at the supplied frequency. LOL!

Can you give me a measurement of the ep125 driver total diameter in mm. Want to compare cutout requirements for retrofitting into existing tower speakers.

I didnt receive a reply when asking about buying 8” drivers from the Bryston line, but I see the 125 drivers are available too, and at a sale price if I understand correctly until Nov 30.
