I find that Dianna Krall CDs are good for checking to see if the speakers are too sibilant. I don't think the recordings are, but if I push the tweeter... -
When you measure, look closely at the woofer response from 300hz to 10k. There can be small problems that hide when the tweeter response masks what's...Leave a comment:

If you are irritated about something, nothing will sound right. I listen for overall tonal balance first. If that's off, I make x-over changes. I have...Leave a comment:

If you make the high-pass 2nd order, the lower end of the mid response will come up quite a bit. It might not add well with the woofer though. Try adding...Leave a comment:

Here's the values entered into PCD. The resistors that are .3 ohms are estimates for the coil dcr. The 12 ohm resistor may be the wrong value. I couldn't...

Measure the response with a mid reversed. It would be interesting to see some measurements if you are set up to take accurate ones....Leave a comment:

Check the wiring for polarity errors.
Switch polarity on the mid, and remeasure. It should have nulls at the x-over points. Don't forget...Leave a comment:

I'm just curious. Is there any reason your friend wants these close to original? Were they his originally, or did he buy them used for the cabinets? Would...Leave a comment:

The offset would affect where the nulls are, and very little more. Using a reasonable estimate is more expedient than spending 2 days trying to pin it...Leave a comment:

Well, I hope he's not still wasting time on that....Leave a comment:

No, I've only used PCD. The filter I posted is a traditional 4th order with a couple of added resistors on the capacitor legs. The Impedance file is one...Leave a comment:

Like this. (Note.... wrong zma file )

I'd start with the woofer. Set a target response in PCD, and try to match it. Go ahead, and speculate on how much baffle step compensation you want. The...Leave a comment:

I can't recommend any designs, but based on what you seem to be looking for, I'd build something with a good 10" or 12" woofer. I built a 10"...Leave a comment:

I have a couple of projectors. I have a Sony blu-ray player / streamer for my source. I run HDMI to the projector, and use the digital out for sound....Leave a comment:

I think others have given you good general advice. I've not heard any of the mentioned speakers though. My advice is a little different. Forget kits....Leave a comment:

It looks like your roll-offs might not be optimized to blend together. Also, when you cross that high, the offsets are more critical. A while back, I...Leave a comment:

How much is the impedance flattened in a typical TL? I have a sealed box with a 6.5" driver that I'd like to cross at 300hz, or so. The impedance...Leave a comment:

Thanks for the sim! How critical is the driver location? The depth seems rather shallow. I'm really looking for mid-range quality improvement more than...Leave a comment:
