Introducing: The Pit Vipers (Ooh Yeah!!!)

[Paul K.]

Very nice Paul!
Very curious to see the folded TL that Paul K and you have been discussing.

Me, too!

Monkey coffins are just fine with me, I remember seeing the huge Cerwin Vega's growing up and wishing I had a pair in my bedroom. The Pit Vipers look great!

That's going to take a VERY powerful amplifier

You might want to edit your crossover schematic. It shows the red and black speaker terminals shorted together

I noticed that also. The crossover part is where I have the most trouble understanding. The simpler and most detailed it can be, the easier it is for me to figure out.

Wonderfully done sir !!!
This is the speaker I'm building !
Would you possibly be able to post a BOM, including values and part numbers fir the crossover components please ? These are the parts I have the most trouble with.

Thank you again for sharing your designs with us.

Nicely done, Sir Carmody!

I love big speakers . . .

:D

Sounds fantastic Paul.
I'm looking forward to traveling on this journey.
As before, if you need something made, just let me know and I'll try to help.

Here's where my thoughts are at right now.

What I have right now is a damn good party speaker. In fact, it's so much better than just a party speaker. The imaging and overall timbre in the midrange and treble sounds "like me" and as with most of my designs, sounds good even with less-than-good recordings. The bass I'm still playing with; it's in "party speaker" mode right now, so there's a push of a few dB around 55 Hz. I want to experiment with tuning it lower and also checking how it sounds sealed, but haven't gotten around to it yet. (part of the problem is that when a speaker sounds really fun, you just kind of want to listen to it, and not mess with it) Also, Paul K and I have been discussing a folded TL, which would require a slightly deeper cabinet, but would probably offer a smoother bass response for the more "serious" listeners. So that may be a smart option as well.

Also, I still do want to try the Dayton GF midwoofers, but don't know when I"ll get around to it. Maybe I'll hit up someone with a CNC in the next few months, I dunno.

So....

What I'm thinking is publishing this, the party speaker version, as Version 1.0. And if people want to take advantage of the summer weather and build a pair, they can join in the fun! Then, as time goes on, I can work on adapting it--or opening it up to suggestions. It's like... I think about popular software platforms like Minecraft or whatever; and it's like sometimes you just gotta put it out there so people can enjoy it, and then tweak as time goes on. What good does it do if it's just sitting on the developer's hard drive, and no one gets to enjoy it?

So I'm going to work on doing a quick and dirty writeup for my site, and put it out there. And as the saying goes: "we'll go from there."

[Serenitynow]

Any more updates Paul ?

Yeah I could really use a CNC guy right now. Where are you located?

[Serenitynow]

I have what I think is a really good crossover going on right now. I'm holding off on making it public because I'm still curious to try it with the Dayton GF180-4. I decided to go ahead and buy a pair of the GF180-4, so they're waiting in my garage. But first I need to buy more wood for the baffles. And since the panels are so big, I need to basically buy the MDF uncut. So that means I gotta bring the minivan. And that means getting my kids' crap out of there... And so on, with more excuses.

Anyway, as far as the sound they're putting out, they're really just so pleasing to listen to. I am so happy with the Peerless D27. its response doesn't look that great, but in terms of how it sounds, it's fantastic. The imaging so SO GOOD. And at least on paper, it looks like it can handle a lot of power; so I definitely think it was the right choice in this speaker.

The other thing I'm really enjoying is that same phenomenon I had with the Tarkus: low frequency separation. That is, when you have a really large woofer to offload the low frequency musical information from the mids, it creates a sense of separation in the low-frequencies. Like bass guitar and bass drum are clearly two separate entities. And even with the bass drum, you don't just get the attack of the bass drum; you get that big, low timbre as well.

As it is, though it's just a really good speaker that like I could easily enjoy for years in my own home, despite its goofy looks. When I started this project, I expected that it would find purpose as a "party" speaker. But it's really better than that. If it was just a party speaker, it wouldn't be so enjoyable across such a wide spectrum of music. And at such a variety of listening levels.

Anyway, so far so good, and I really hope you guys like the end result!

Thank you for the update Paul.

I'd like to offer my CNC services for anything that may be useful. I understand that shipping may be cost prohibitive, but just in case, I'd like to help if I can.

How do these compare to the Tarkus ?? Was always wanting to build those, but alot of the components are now really hard to come by.

Thanks again for everything you do for us mere mortals 😁
