DIY floor drainers with kicker components sorry

These speakers were my uncles built years ago and lately the sound is I. And out of them. They almost sound mono at times and stereo at times . He had them custom built back in the 90’s . I’m not sure if it’s the crossover or it’s the receiver cause they’re both old as dirt. The receiver is one I picked up from good will actually and this is the first time I’ve had any listening problems with speakers

DIY 4 inch Speaker Setup in Theatre Black Box: Cable Recommendations

Hello there,

I'm building 10 DIY speakers using 4" full-range speaker cones for a theatre show. We plan to hang them from LX bars above the stage. I’ve measured everything and I need around 450 metre of cables.

I'm looking for a reliable and affordable 16AWG speaker cable that doesn’t burst the budget given. Any recommendations?

Thank you in advance!

Repair, Replace, or Hybrid?

Hello,

I have a large garage and the below equipment. I am looking for a system that would be good for large parties and playing music when I workout. No DJing, just from playlists. Garage is 20' x 40'. Location is USA.

Some of the drivers on the Pioneer box possibly damaged. Music sounds just ok, but I know it can be better. Bass and high ranges are the real issues holding this back

AV Receiver: Kenwood KR-V8070 (20+years old possibly)

Towers 1 & 2: Pioneer CS-F9900 (Also old, some speakers cracked and replaced, some damaged?). Frequency range is 32-20,000 Hz, Impedance is 8 Oh, and max power is 150W

Subwoofer: RBH 9" (?) externally powered.

The subwoofer has a blown out sound no matter what I set the power level or crossover to.

Questions:

Would it be better to replace all the drivers in the pioneer box with something new? If so, any good recommendations?

Does my receiver need an upgrade to where I can control the drivers better?

Is the subwoofer worth keeping or should I rely on the bass from the two tower speakers for everything?

Thanks for any thoughts.

USB 2.0 speakers

Hello all, Looking at making a 2.0 USB speaker as a little project. I’ve created 2.0 and 2.1 systems before using Dayton audio amps. Although, I’m wondering if it’s possible to create a 2.0 with an amp which uses signal input through usb and powered by the usb. It’ll be for the Mrs who isn’t a fan of blasting music so power provided from the usb would be fine. Any thoughts let me know!

Is my JBL 10" sub blown (vid)

Hi

Is my sub blown ? It Sounds like air escaping or a high pitch rattle/vibration.

It's a JBL soundbar with 10inch wireless subwoofer.

Have a friend with same sub so after checking everything in the box etc to find the issue I removed the speaker and installed on my friends JBL sub box and confirmed the noise is definitely coming from inside sub/speaker itself.

Attached is a vid

Any help/advice is appreciated.

Dead bose soundtouch 20, can I use external fosi amp to power?

As the title says, I've bose soundtouch 20 speaker. It's dead, and I'm from India (not much scope of getting it fixed) I've successfully opened it up, I love the sound quality of st20 so was thinking to have it saved by powering it using external amp from fosi audio. Is the idea good? Also, bose doesn't mention wattage specs of speakers, of the idea is good, how much power of amp should I go for? Ps, I've external active sub also, hence subout port is necessary for me to have which fosi is giving in few options of their amps. Im already excited that if it works, I'll finally have losless audio on st20 speakers. Thanks in advance dear audiophiles

DIY class-D amp build - need confirmation: too many Amperes not an issue, correct?

building a dual-mono to drive a pair of Magnepan LRS - ordered a dual-TPA3255 board ("SAMP-200" advertised @ 1200w) and now sourcing a switching power supply. Found a 40V 30A unit that should do the trick as I've read of some frying said board @ 48V.

appreciate any and all comments and direction, this will be my first build.

What are this plugs in my amp?

I just bought an amplifier (Wuzhi audio ZK-HT21 2.1 ch 160W X2 + 220W. I have bought a lower powered version before and it didn't had this plugs, also, in the pictures I found on the internet they don't have them either, so what are they for? One of them says "subwoofer audio output" but there's already the outputs from the back and this one's have 3 pins!?

Can you turn mono speaker to stereo?

hi, i am not at all into audio or anything like that, but i just wanna ask some more experienced people about the speakers i just bought for my laptop setup recently.

so its a cheap speaker, and it comes in to channel making it 2.0 (i think?) so my first thought was that it would be a stereo speaker but after testing it with those L R speaker test on yt, apparently its not stereo(?) it turns out that it always plays the same audio from left and right speaker, even after i tweaked with my windows settings..

now my question is can you make a mono speaker, stereo?

Need help improving first speaker design

Yet another newb here. I'm building two sealed enclosures for full range speaker drivers for my desktop gaming PC. I've designed and built a prototype for my very first DIY speaker which sounds pretty amazing if I don't say so myself (compared to my old ones anyways). My second design fits my speaker driver specs for physical volume by <1% error. I'm very happy with it but I think it can be improved. For that I have a few areas for questions, things I don't understand yet.

  1. Should I mount the speaker on the outside or inside of the front panel? Does it matter and why?
  2. When designing an enclosure, should the driver's physical volume be considered?
  3. Are thicker sides always better or are there downsides? I think the rule of thumb was 2cm.
  4. If my enclosure volume is precise, do I need stuffing? Is furniture stuffing the same as speaker stuffing?
  5. I am using shielded cables but since I am DIY'ing my enclosure, should I shield the inside of the enclosure too? Does it have to completely enclose the speaker driver to be effective? Does shielding do anything if it isn't connected to ground?

I know it's a lot so feel free to answer some or all of my questions. Any other tips or improvements are welcome too. Thank you! Here's a picture of my enclosure design:

Do I need two amps separate or dedicated for each speaker type?

Currently our home amp is 600Watts per channel class A/B.
Specifications:

  • Power: 600W x 2
  • Frequency Range: 5Hz to 100kHz
  • Load Impedance: 4-16
  • Input Impedance: 10K-22K
  • Input Sensitivity: 350mv
  • Total Harmonic Distortion: < 0.1%
  • Signal-to-noise ratio: 80dB 
  • Power Supply: AC 220V 50-60Hz

All of the output channels have been occupied both A+B sides by the speakers we have

Our subs are 2x 8ohms per channel in parallel making it 4ohms (200 watts per woofer, 400 watts per channel). I have also connected a small box that contains the mids and highs.

Should I get a 2nd amp meant only for the mids and highs? (combined power of 200 watts with mids + highs per channel)

I know this amp we bought is way too powerful for our current system

Also we usually use about 1/8th of the power most of the time as it really powerful

Help with 2 in-celing speaker in house I bought

Hi everyone,

Sorry flair is wrong, didn't find one for recessed speakers.
I bought a house, and it turns out there are 2 in-ceiling speakers in the kitchen. I finally found where to wires come out of and made sure they connect to these speakers using a battery.

I want to find and suitable small bluetooth amp to drive them but I'm a bit lost with power wattage necessary. I unmounter one of the speakers to find RMS info, but only got brand part number.

It's paradigm, part No: 2010901020. (See image, sorry it might be a bit distorted)

I tried searching a bit, but I'm mostly getting results for ebay listing of paradigm studio 100 V3, or CR-60, that seem to be tower speakers, without all the info I thought I needed. For the CR-60 it looks like it says suitable power 15-80W (if it even is that speaker). Would I need an amp with twice that (for 2 speakers)? How much would I really need in terms of power?.

I though maybe someone here could help me with that.

Thank you.

Edit: Added the extra info on what I found so far.

I’m using a crossover (Monaco’s DNH-185) as a tweeter high pass filter at 5.5kHz. What could I add to either make the crossover frequency higher at 6.5kHz or make the slope steaper. Currently the tweeter also get some signal at 4-5kHz which I don’t want.

TPA6130A2 performance with high impedance headphones

Hi, I'm currently in the design phase of a device that needs an headphone amp. I wonder how the TPA6130A2 performs with higher impedance headphones, as it is feature wise exactly what I was looking for. Unfortunately the datasheet doesn't provide performance characteristics above 32 Ohms, however the output voltage seems to be more than high enough.

Whats your experience/thoughts on this amp?

Highest Fidelity Transducer for Bone Conduction Headphones DIY

I am looking to DIY some BT bone conduction headphones in a Dirt Bike helmet so I can listen to music while I ride but still hear my surroundings/radio.

Ideally, I would have some transducers in cutouts in the helmet padding and then have the amplifier, battery etc outside the helmet.

Obviously this is not going to be an audiophile grade setup but I would love to get a fidelity level that is acceptable for music. Are there any transducers out there that can produce that quality?

I have also looked into getting a pair of Shokz and disassembling/repurposing but havent been able to find much. Has anyone tried this route?

Help Needed - Setting Up Indoor & Outdoor Speakers for My Shop – Advice Appreciated

Hello r/diysound,

I'm hoping some of you can help me out since this isn't my area of expertise—I usually stick to telecom and networking, but I’m always up for a challenge. I have a 30x30 shop where I want to install speakers (hardwired is fine), and I’d also like to add outdoor speakers for a hangout area, mounted on the exterior of the shop.

I figured having two speakers inside the shop and maybe two speakers on the exterior are more than enough for what I am looking for but you will know better than me.

Ideally, I'd like to have the option to control the indoor and outdoor speakers separately, so I can turn off one set while keeping the other on, and vice versa. I don’t need anything extremely loud, but I do want clear sound with decent quality. Heavy bass isn’t a priority for me.

As for the budget, I’d like to stay under $1,500-$2,000 if possible, but I’m open to adjusting it based on what this project might require. Any advice or recommendations on the amplifiers and speakers would be much appreciated!

Does this make sense- Repairing powered shelf speakers

I have a set of well loved Behringer Studio50/USB speakers in which the amp was drastically killed from an electrical surge- Scorch marks on the PCB & completely exploded components... However the drivers & enclosures are great.

I'm looking into resurrecting them with a Fosi Audio TB10A, or maybe spend even more time and integrate a Dayton KAB-2150

I figure it's going to take me $USD 50-100 and at least couple of hours to get it all built and dialed in, and I've done plenty of electrical work so I know what I'm getting into. (not to mention feature creep-itis)

On the other hand, I can pick up a set of Amazon specials (like the Edifier R1280T or the Swans OS-10) for around $100-$150 and they would suit my needs OK, but without the time outlay.

What would you do?
