Re: Modifying an existing 800Hz crossover to 1000Hz

Often what you hear as distortion is actually something rattling in the box. Get it "distorting", then start putting pressure on the various components - you might be surprised what it loose and rattling. It's certainly worth a try before spending money or digging into the electronics. OK...

Re: Modifying an existing 800Hz crossover to 1000Hz

I wonder why Eminence would say that the LA8 is a midrange if it's not a midrange. They don't. The call it a mid/bass, which means good from 100Hz. Midrange drivers are generally good only to 400Hz, and have higher sensitivity and midrange extension than mid/bass drivers. I went with the LA8 becaus...

Re: Modifying an existing 800Hz crossover to 1000Hz

Is the LA8 not a dedicated mid? It is not. We use them in DR200 for full range operation. The Alpha 8 MRA is a dedicated midrange driver. I'm hearing a bit of distortion coming from the midrange when playing the lower notes on the E string. You shouldn't, not even with a 300Hz high pass. Is the dri...

Re: Modifying an existing 800Hz crossover to 1000Hz

The knee is where the response rolls off, it looks like a knee. Check your xover for loose connections, and that it's securely held. Experience of other users found what you're describing coming from a solder joint, board rattling in the box, or midrange not sealed tightly to the cab. OK I'll check...

Re: Modifying an existing 800Hz crossover to 1000Hz

What about just putting another cap in series with the midrange, between the crossover's output and the speaker? What about the woofer? Its low pass frequency must also be raised. Besides, going from 800 to 1kHz will have only a slight effect. I don't know why you think there's too much low end in ...

Re: Modifying an existing 800Hz crossover to 1000Hz

The problem is that you have to change all of the components, on both the high and low pass sections. In other words, an entirely new crossover. OK thanks. I thought it might be easier than that. What about just putting another cap in series with the midrange, between the crossover's output and the...

Modifying an existing 800Hz crossover to 1000Hz

I built a bass cabinet using an Eminence Kappalite 3015LF Neo 15" Driver and an Eminence LA8-CNMBA Neo 8" Midrange crossed over at 800Hz with an Eminence PXB2:800 2-Way Crossover Board 800 Hz. I first tried the cab crossover at 500Hz but too much bottom end was getting to the mid. I find t...
