Hello. I decided to release this video in the format how was my work day or just a video for a cup of coffee. It does not carry any semantic load in itself, just sharing a certain chronology of processes among the past days. By the way, if you come up with this format, please write about this in the comments.
Little by little I’ll cover what is currently being worked on. Before putting up for sale sets of HF boxes, which were previously lit in the test with 8 tweeters on my channel, I decided to put together a three-way speaker, within which I could describe in more detail to the potential buyer the sound quality of the finished products. The column, of course, turned out to be thermonuclear.
Woofer delivered from cheap acoustics Pioneer CS-5030, which, by the way, was my first home acoustics in my school years after the music center. The diameter of the emitter is 20 cm, the case used by Fostex FF225WK for 45 liters. I plugged a bass reflex in front, and installed two pipes in the back, which, by the way, are absolutely not matched to the Pioneer speaker. I don’t even know at what frequency the pipes are tuned.
Since I do not have midrange speakers, I used the driver from the JBL L300 speaker, however, I was too lazy to hang the lens until it did. The filter was assembled "on the knee", the details are not the simplest and cheapest, by the way, they will also need to be selected, while only trying to match the low and mid frequencies on the frequency response from the first attempt. The midrange plays up to 10 kHz, for coordination with the tweeters for tests, I will cut off the driver with a second-order filter in the region of 5-6 kHz. The woofer and driver are cut in second order. Let's probably listen to the column in this version.
Yes, to bring the sound to the desired condition, there is still a lot of work to be done. I don’t know if you are interested in such a continuation, you can try to squeeze music out of such a set. In school years, it was my dream to carry out such an upgrade: to buy a driver with a horn, and even one, and it’s already wildly improve the sound quality ... True, I still did not understand what a rhythm was, I just wanted the bass more and the plates brighter. By the way, I’m just now thinking that instead of a JBL driver, you can pick up a TAD driver, it just plays smash. And since such a booze went, why not also drive the FOSTEX FF225WK with all the drivers? In general, here I shift the responsibility to you, dear viewers, if there is activity in the comments on this subject, I am ready to provide you with material for review.
So, let's listen to something else, for example, Sarah K.
Yes, of course, the sound is dirty, sluggish. I completely forgot that the Sony kit plays, also visited the set in my videos. Therefore, such a sound. Even after our upgrade, he is not able to play music recklessly, articulated. Of course, in the factory condition, it does not represent more value than a box for bolts and nails.
Well, it's time to say goodbye. In the next video, I will finish the filter, maybe we will pick up with you the best option for the nominal values around the already set ones, thereby adjusting the tempo and rhythm, we will pick up the phase inverter. Yes, we need to return the endings in the sound: pay attention, they are not now, the sound is ragged. Using the links in the description, you can download several excerpts from the sound of the column in this state.
In parting, as always, I wish you a clean sound and a desire to force yourself to understand why monotonous and amorphous musical noise cannot be called music, even if you have a system at the cost of a spaceship! Everything needs to be coordinated and correctly tuned, collecting natural sound bit by bit nuances and subtleties. Bye everyone!
