First look at Punktkilde – New hifi drivers
There’s a new name in HiFi drivers – Punktkilde. Although, you may not have heard of them, you may have heard of their sister company, Scan-Speak. Scan-speak, often referred to as some of the highest quality HiFi drivers one can buy, designed every one of these Punktkilde drivers that I recently received for review. Once…
Powered Voxel Sub
Not too long ago I had a patreon giveaway. The winner won a custom speaker designed by me. Once the winner was chosen he wanted a custom subwoofer that would match his already built soundbar. Since he did an amazing job, I knew I to give him something that would at least match the quality. …
The Best Amplifier Under $150? SMSL SA300
The SMSL SA300 is loaded with features and customization. Could this be the best amplifier under $150? The amplifier itself came with a few pamphlets and a user manual. Although the user manual looks small, it was quite thorough on the operation of the amplifier and remote control. The box also contained a USB cord for the DAC, a massive power supply that is capable of outputting 162 watts, a Bluetooth antenna and a remote control.
Building a HiFi Test Amplifier
Today I am going to be teaching you how to build a HiFi testing amplifier. The first thing you need to do is figure out what amplifier to use. You and I may love curves, but not on our frequency response. For this you want a flat smooth response, so you hear exactly what is…
If I need to change the tweeter can anyone help with pointing me in the right direction to the Faital Pro 6fe200 4 ohm ZMA and FRD files so I can redesign the crossover?
If you wanted to change the compressions driver, I would encourage you to build the Cinema 6 instead. If still uses the same mids, but changes the compression driver to the de250-8. If you want to design it from scratch with all new drivers, I would recommend picking up Dats and a calibrated microphone. and posting your graphs. That way we can help you design it from scratch. Those would be the best options. If you happen to be in the UK, then I would suggest checking to see what Sound Imports has.

KL-250?
What do you think of making a much smaller unit, say with a pair of PC68-4 and the PTMini-6, for a small viewing space? You could get up into the mid to high 90 dB range for about 15-20 watts / speaker, and the cost would be around $230-$300 for 5 passive speakers (x-over included, depending on how crazy you go and what it would actually measure in box). and whichever sub you would make, 5-1/4″ to say a 8″, might only tack on anywhere from $20 to $60 more. (for ~$28, the Peerless GBS-135F25AL02-04 models near a 0.5CuFt box with an F3 of around 36 Hz. Low profile and inexpensive.) And if you go shopping on Ali Express, you could do 5.1 decoding and amplification for inexpensive. Somewhere between $400-$500 for a plug and play system (depending on wood prices).
Only issue I see with the PC68 is that no matter what box type you use, they tend toward a large hump in the 150 Hz area. At least that’s what WinISD shows. I wouldn’t know for sure unless it was measured as such.
trying to find the build plans for KL-650 copies – they dont appear on your shop?
also to note, when i follow the link from youtube, its a dead (404 error) link.
pls advise, thx
Hi, Is this plan still available or buyable ?
Thank You, Etienne
These were a great project, and the sound is exactly what was needed. Clear, rich mids… Speaker building as a hobby didn’t stick, but building these, along with the subs, was definitely the way to go. Thanks!
