The Goldwood 4028 drivers have no + or - markings. Does it not matter which is what or is there a secret handshake I’m not aware of? After testing them as outlined in the plans, make sure they're all wired the same. Once the cab's assembled, play a sine wave at the crossover frequency and measure t...

in unraveling and reverse engineering his intellectual property. To be honest, i don't get that part. Maybe i am just to far away from that, but wouldn't be the only benefit i could gain from that to draw a plan and build a box...like the plan i already bought from bill to build this box? This seem...

Time for the grumpy old sound man to throw a little cold water on the discussion. If you spend half of the time on learning how to properly EQ your system once it's built as you have on trying to choose a cab, you'll end up with a much better sounding system regardless of the sub you choose. You an...

PM me your email address and I'll send you a link to download the spreadsheet I've created in making sense of some of this stuff. It's not super organized, but you're likely to find some of it enlightening. The equations are solid.

there haven't been any useful discussion about using HornResp Could you get deeper into that, briefly? Because the common idea here is, that the software is somehow bad or faulty? Is there other software? Or what is the point? It seems a totally fitting tool, esp for the choice of drivers before bu...

Ideally, you'll want the bottom of the DR's to be at least a foot above the audience The top one yes, the bottom one on each side has to fill the front area. There will be a pair on each side (at least). You want the bottom cab of any size stack above the heads of the crowd. Off axis attenuation be...

In the fifteen or sixteen years I've been active on this forum, there haven't been any useful discussion about using HornResp. Just my experience that you'll have to rely on other forums for that informati0on. You could try sending a private message to user Wylandright206 . You may also consider rea...

Interesting, thank you for sharing that. Where did you got that numbers from? Simulating the cab with the drivers TS-parameters and manually adding the stacking and plating-part? I would be curious to try this out in different frequency points and with different driver-combinations. I fear i have t...

A few years back I put together a spreadsheet to help me see the picture a little more clearly. It's not completely comprehensive and this particular calculator I created only compares the cab's at 40Hz and assumes full width cabs based on driver size. The results aren't the full picture, but gives ...

Doesn't relate directly to OP but: Seth, in the above quote you said T60 with 15" driver in a 20" wide cab, however the plans clearly state following. "Recommended fifteen inch drivers are the Dayton 15LF500-8, PRV 15SW2000, Eminence LAB 15 and LaVoce WAF154.01, used in a 27 inch wid...

Only dj, rather experimental subgenres from psytrance and dnb/breakcore...no live band.... If you're looking for maximum output outdoor, in the frequencies that can be reasonably be reproduced, Titan is the only way to go. If you build full width (36") 15" loaded T48's you would be WAY ah...

...Volume-wise the question is, if it would be enough to have just 4 of the packages (8 t30 loaded double 10) or if it's worth it to double it (8 t60 loaded double 12)... I apologize if you've already mentioned it in the thread, but tell me a little about your intended use; most likely venue/s, ind...

Food for thought regarding the double loaded cabs... pretty much the only time a double loaded cab makes any sense is if/when you need to wire the drivers in series to double the cab's impedance in order to run double the amount of cabs per amplifier channel. In nearly every other circumstance, it's...

Love the connective sentiment in this corner of the internet. You guys are great! Thanks for the holiday wishes. Indeed,.. Merry Christmas and Happy New Year to you guys. 2026 is gonna be an interesting year for me, 2027 even more interesting. Just uploaded my 33rd YouTube episode for the whole &quo...

...Jigsaw and orbital sander is being Considered too... Me personally, if tools were budget dependent, I'd choose a router and circle jig over jigsaw and sander. With the wood you have, an old school sanding block will be more than sufficient to deal with any sanding needs. Router with a flush cut ...
