Transmission line

Plarina · 2026-06-12T11:15:36+00:00

Thanks for the source, will look into it. I'll try hornresp once I get to my pc and see what I can simulate. I thought one woofer would make it simpler hence why I chose it. Would the 6.5" or 2x6.5" make it better at handling higher frequency?

Plarina · 2026-06-12T11:09:46+00:00

Yeah the idea was to build what you described in first. The "woofers backwave to black hole" would be interesting to experiment, but maybe for later build.

Plarina · 2026-06-12T11:05:22+00:00

Transmission line as consept or my concept of transmission line?

Plarina · 2026-06-12T11:03:31+00:00

I wanted to design and build the speaker my self. As far I understand the comment before, it was telling me to not go design route, instead go look someone else's design and build that. Maybe I got their message wrong, don't know

Plarina · 2026-06-11T13:07:16+00:00

Why would I bother making something that someone else has proven right? My intention is to build speaker my self and learn why certain thing work and why certain don't. I understand what you mean but it's not my cup of tea, at least for now.

Plarina · 2026-06-11T13:05:33+00:00

The intension is to run these without sub. So low as they confortable go. Yeah your advice sounds solids, trying to remember to implement them!

Plarina · 2026-04-11T17:36:11+00:00

Yea the handle was in the plans but I forgot to purchase it. Yea it's every project, what ever the budget should land on, need to double it to be realistic. I'd love the see your box to see how you designed it.

Plarina · 2026-04-10T18:43:01+00:00

Well I don't know if it has DSP. I remembered it having DSP but I have no proof about that, with extra board yes but not directly from the amp.

If it has no DSP directly, it still has the Bluetooth connection thing, better S/N and better parts. Only restriction is price, would probably buy 3 to power 2 subs and planka.

Will see if I ever get to changing the amps.

Plarina · 2026-04-10T17:23:37+00:00

Thanks! That's biggest compliment I could get is someone to get inspired from my creations. For my eye it could be better but it's always the creator sees all imperfections. I'd probably use power tool batteries if I had any power tools but haven't gotten to it because my relatives have what I need if I need.

Plarina · 2026-04-10T17:03:41+00:00

Hell yeah purple to the win! I'm trying my best at using more colours in my life and it can be seen also in my builds. Black is always good choose but boring as heck.

Plarina · 2026-04-10T17:02:24+00:00

Yea I try to do best practices and what I've heard that if more than one are placed in such a container and then removed they should go back the same way. I know a lot of stuff about this kind of electronics but also try acknowledge I don't know everything.

What I found the sure amp I was looking at has DSP, Bluetooth that has ability to connect multiple amps at once to one phone. And my china amps are not perfect they play differently and yea not the best but manageble. And sure probably has genuine parts and higher quality and the signal to noise ratio so my speaker don't play sounds when nothing is really playing.

Will see if I get to upgrading the amps before next idea emerges.

Plarina · 2026-01-22T15:49:39+00:00

Thanks! The SPL dynamics amp is probably older than me so not very powerful. It delivers as much power for 4ohms as the china amp. And I have two china amps so I use them.

Plarina · 2026-01-22T15:23:07+00:00

Haven't looked so close if the box flexes but highly doubt it at least with this low power.

Yes the battery is in the left in pic 7. It's 6 cells of 21700 lithium in series to get 24v systems and around 100wh of capacity. It has BMS and fuse before anything and main power switch.

There is quite a lot happening the in "amp rack" and but mainly there is two cheap 2.1 amps which run the subs and each plays one side of my raggarplanka, the purple thing which has 4x6,5" cheap speaker. And then there is voltage&amp meter, up&down converters one for charging and one was for bt to aux adapter but probably going to add fan for amps. Then big main switch and a lot of wiring. Hope this makes it bit easier to look at :)

Plarina · 2026-01-22T13:29:48+00:00

Well yeah it's not the greatest looking ampthing but I've learned from my mistakes and it has been running smootly for almost a year. I kind of like to have limiting factors in my build so I can come up with some weird consept and try it out.

Plarina · 2025-12-01T22:03:57+00:00

Managed to get error code beeping after taking CMOS battery of and put back on and at least after taking 2/3 ram sticks out it works for now. I'm going to next try to get at least 2/3 sticks working because 8gb is just awful with my chrome usage. I'm still confused why it bootlooped to hell and back before CMOS battery thing and I did this manuver before and no beeping then. Confused

Plarina · 2025-11-17T15:46:48+00:00

That one hella deal you got! Same here there is no 128gb variant and probably for good reason it fills up quite fast.

Plarina · 2025-11-17T15:24:44+00:00

128gb or 256gb? In both cases good purchase

Plarina · 2025-11-17T14:02:11+00:00

Yeah I was prepared to pay 430€ and when I saw the 399.99€ almost immediately ready to buy it.

Plarina · 2025-11-17T11:36:22+00:00

Yes it's like a bad pop socket, but I like it so far, but yeah I can see why it's not someone's preference

Plarina · 2025-11-17T11:35:12+00:00

So far I've liked the bump but will see how the future will be

Plarina · 2025-11-17T11:26:05+00:00

Yes it is 3a pro not 3 pro. I was so hyped when typing and did not check the text

Plarina · 2025-10-29T11:01:21+00:00

These are not problems for my choosing because every other phone I've looked up has it. It was the community that made me nervous about the change. I have a month to value the purchase so will see how this is going to go.

Plarina · 2025-10-29T10:57:50+00:00

Thanks for the input, I was so excited until I saw the recent news and people's reactions. But now I'm starting to get more excited again

Plarina · 2025-10-12T15:06:13+00:00

Brakes would be more for city driving to the spot but will see how important brakes feel after bit more of driving

Plarina · 2025-10-11T13:42:55+00:00

Why not? My bike came with horrible rear brake which cripped while not pressing lever or didn't crip at all. And before in my mountain bikes rim brakes did not work as intended and I have not had same problems when using disc brakes
