r/SoundSystem

Was waiting for a while on the final parts and glad to be testing these after John's casually dropping a message that they may be better than the JMODs (but with less output).

Got them fired up yesterday and did a nice outdoor listening session.

He is right. The imaging is insane and the amount of bass output makes them quite viable without a sub for smaller setups.

HypeX plate amp, relatively easy to move with one person, that MEH sound we've all come to love.

Really looking forward to playing around with these more and putting them through their paces.

Am thinking of building an mt-130 mid section like this, think it would look pretty sick and then have a compression driver/horn on top in a separate box, could this be done without changing the sound.

Any idea how much this rig would cost?

Finally finished my Solana build. Big man tings shout out to John for the design and for providing the step files for the low tuned enclosure. Also shout out to @tliptak on this forum for hooking up the 3d printed wave guide. He did it in two parts which made assembly pretty easy.

On the waveguide I used bondo on the seam and build up automotive primer to fill the seams and smooth the surface to 800 grit. Then burple spray can automotive paint and then 2000 satin clear coat for the matte finish. Matte finish looks great and is more forgiving that gloss. It kinda looks like colored leather. I had a little trouble getting the threaded inserts for the drivers to adhere to the PETCF with super glue so I ended up using epoxy on some of them so they wouldn’t strip.

I modified John’s enclosure to accept the Hypex FA253 instead of the FA502. The two 250w channels bridged to one 500w channel at 8ohms, leaving the 100w channel for the CD at 16ohms. Since only 8ohm DH450 are available in the states I got the 16ohm from TLHP out of France. Highly recommend these guys they arrived to the states in like 3 days FedEx with minimal duties.

I had the CNC cut two sets of enclosures in case I wanted to make a second pair or I messed up assembly. Box assembly went mostly smooth but I over sanded a bit in some places. I finished with 3 coats of Osmo 3051 raw to keep them raw wood look.

I ended up buying a bambu P1S for $400 to print the low tune ports. I thought about modifying the step file for the low tuned port with screw tabs so I could swap the port from the inside for the mid tuned version. I might still do this if I don’t build the other set of enclosures. I think if you’re on the fence about 3D printing, it is pretty easy these days I recommend just grabbing a printer and having a go at it.

So far just sticking with the suggested EQ in the plans but will take measurements later. So far I’m incredibly happy with the form factor and the sound quality. I ran these really hard for six hours, touching the limiter a little bit. For house and techno they really sound punchy with great separation for mixing records. The low end is sufficient for a small place and party. But for hip-hop and other bass heavy types of music, you would definitely would benefit from a sub.

Currently wrapping up some Type O 2x12 to pair them with.

Impulse bought an A30 pro series power amp for 25 euro’s. Seeing some crazy prices online, is there anything to them except collectability? Should I just flip this?

I had some MDF left over from another project so decided to test build a large slot port 29/30hz tuned reflex for the 18sw115. I wanted to try doing a full rebated build using just the router and track saw, so I made a jig so that 'IF' I like the performance I can build some from ply for my little rig.

The goal was not ultimate SPL, but a focus on 25-65/70 with a clearsish response to at least an octave above at 135/140. The cabinet is a washing machine sized 288L, as thats the largest I wanted to go - plus I could always install it in the kitchen for an awesome kitchen party 😅.

The reflex volume is 133L gross with a port area just over half sd at around 640cm2 and 1.1-1.2m-ish in acoustic path length. I'm going for a small volume low tuning which will result in a non flat response, but with the aim of using a low shelf instead of a high pass to protect the low end and flatten it out and keep the delay as low as possible (DSP assisted reflex).

I've measured some used 18sw's using DATs and used the hornresp semi inductance model, interestingly with both drivers the fs comes in above spec sheet despite having been abused in hogs before. I'm not sure which to believe, but either my measured values or spec sheet gave usable responses so it was worth a try.

So ... My question ... How long before I melt a coil? the hornresp model peaks at 3.4kw at 30hz 126db 1m 2pi, the question is how this will average out? The power levels drop off fast and by 40hz are no problem, but then its being crossed low at 65hz so the average will still be fairly high. Comparing the filter to other designs, they seem to do similar with around 3-4db max boost around fb.

I can't wait to get this outdoors and some proper measurements made. Initial testing on a t.racks dsp 4x4 and one channel of a teac a-h300mkii and it really sounds great.

Hornresp came out pretty damn close, the port resonance wasnt quite right but everything else looks good. Akabak BEM also matched hornresp when using the spec sheet figures, but more accurately modeled the port resonance a few hz lower as it really came out. I wasn't sure on the measured values for the 18sw in akabak so cant compare there.

Just some little update on my Solana build. Running them via t.racks dsp206 and FP10000Q for now. Measurements came outa pretty well with the standard EQ-Settings from the JW documentation. The DH450 needed more Gain reduction than expected (~-13dB instead of -10dB), but I haven't finished fine tuning.

Hi guys, anyone know what subs concrete lion are running? Been trying to figure it out for a good while - they seriously impressed me last year at St. Paul’s and my research tells me they were running Paraflex, and in the old photos I can see that.

However, when I saw them at St. Paul’s it didn’t look like paraflex? More like a scoop with the driver enclosed. (Have attached photos to show)

Anybody with more knowledge know what they are?

Hi guys, i am a sound tech located in the Netherlands. Ive stumbled upon a small venue with some Pioneer PA speakers, 4 times XY-3B and 4 times XY-218S subs.

Ive noticed some audable issues around the 100hz and after measuring the room it was clear that it was totally out of time. Since i didnt want to change settings in the current Powersoft K-series amps, ive flown in some new Powersoft Unica amps.

Ive noticed already massive improvement after using the presets from the preset manager.

But the presets are locked on the limiter settings, as the Kseries limiters are completely off, i am not 100% trusting the settings in the locked presets.

Ive tried to ask Pioneer/Alpha but it seems: as they Discontinued the Speakers, they are not able to even locate the unlock key for the Powersoft presets 😆..

Does anyone in this community had previously the unlock code for Pioneer, or has any idea how to achieve them? As i want to make sure that they are set correctly.

Yes i am asking for the greater good, as i already created my own custom presets because of this.

I hope that we can at least restore some legacy ourselfs.

Thanks 🙏

Just doing the last finishing touches before carting it all over to Suffolk for Uncanny Valley Festival next weekend (tickets still available 😉)

Got 18” Celestions on sub, 18” RCF on bass, 12” Fane on mids and 1” P-Audio comps up top. TSA4-700 for treble, Jam K16 for bass, running full 4-way stereo controlled by a dB XCA28.

Over 9 feet of 360° power.. As far as I know this has never been done before (but I’d love to see others!). The closest I’ve seen is the old Katabatik system with omni tweeters

I’ve put a switch in the back to allow me to run 4-way with the scoops on sub or 4-way with the hexagonal lock boxes on sub duty and the lower mid driver on kick - to allow for more versatility in deployments. It’s mostly optimised for dub but also really well suited to the more experimental/ambient/sound art side of things, where you might want to set up on e.g an art gallery.. So 18” scoops aren’t necessarily appropriate lol

Huge thanks to everyone that’s helped, weighed in, lent tools or time, and encouraged this silly endeavor

Check out @awassa.sound for more info about upcoming events. Hope to see some of you in the fields this festival season xxx

Random photos from the build. I used the three 15deg panel design. Had to grind down the edge of the driverchassis a bit. Won’t be possible to remove the driver without removing the bottom piece unfortunately. Rest came together relatively nice. Took some extra pictures showing the cable routing as these are hard to find online.
