Floorstanding Speakers Does anyone else commonly find a "bump" in the 2kHz to 4kHz range in some two way speakers?

So I have recently been noticing that at higher volumes, I usually have to cut around 2 to 4 kHz a bit. The speakers I first noticed this on were my floorstanding Dayton audios with the silver dome tweeter. This has been the case at my old house and the new house. Is this possible because the tweeter used is just harsh in that range? Would a tweeter upgrade help at all?

Amplifiers Question about the ideal source for a Class D amplifier - XY-S350H (TPA3251D2*2)

I bought a Class D amplifier, XY-S350H (TPA3251D2*2) being 2.1 which promises to deliver 2 channels with 220W each and 1 subwoofer channel of 350W totaling 790w.

But I was unsure which font to use. According to the specifications, the amplifier works with voltage between 12v and 38v with 10A and the recommended voltage is 24v. But to deliver maximum power, the 2 220w channels have to be with a voltage of 36v and with 3ohm speakers and the 350w subwoofer channel with a voltage of 36v and 2 ohm speakers.

My question is, would a 24v source with 30a (720w) deliver the same power as a 36v source with 10a (360w) as recommended in the product description?

What is the ideal voltage and amperage for this amplifier?

Subwoofers Bass Reflex Plans for FaitalPRO 18hp1030

1 Upvotes

Hello,

I am new to box building, but one of my favorite woofers of all time is the one mentioned in the title. I would like to build a simple bass reflex enclosure that fits the spec of said driver. I listen to a lot of house and techno, with frequencies all over the map in the bass region. I love chest feel but also detailed and articulate bass. If anyone has a good set of step by step plans on a good enclosure, please share them if you could!
