It does apply. It's critical with tweeters, not so much with woofers. But the flip will put the woofers closer together, which will improve the results when stacked.

The only way to know for sure if there's a placement issue is to measure the result, which is easy enough using a phone RTA app or REW software. You could aim it down, but that would require using at least 12 inch legs. As to the other question: https://www.harborfreight.com/8-piece-right-angle-scre...

You can find on line charts that compare different Q values. I prefer somewhat higher than the 0.7 of Butterworth.

It's not a textbook crossover. I adjusted it to give the best results. There are only a few textbook crossovers, identifiable by their Q. Simple calculators only offer the usual Q choices, to keep things simple. You don't need to use a given Q, you can use your own. It's like speaker modeling softwa...

A pair of NSD 2005-16 can be wired parallel for an 8 ohm crossover. Double the capacitor values, halve the inductor value. The low pass filter is unchanged.

Any driver with comparable specs to the F151, including size and weight, will do. Don't rely on catalog descriptions, look at the data sheets. That automatically excludes cheap drivers that have no data sheets.

They retailed for $180 USD.

If it doesn't do it on one string and does on another it's the bass.

Word: Mancave.

Above or below doesn't matter, or even somewhat to one side, which mine is. Being visually oriented creatures our eyes tell us where the sound is coming from, over-riding the audio directional cues. You would only locate it with your ears if your eyes were closed.

I wouldn't dismiss going higher out of hand. My 55" comes within 8 inches of my 8 foot ceiling. Sitting on my recliner or my reclining sofa the angle is perfect, and that's with only a moderate recline angle. As for the window it should be draped anyway.

It will keep up, the only reason to change is if you want to go lower for HT low frequency effects.

It's not so much about louder as it is sound quality. SLA Pro isn't hi-fi, it's not supposed to be. It's a lot better than the average woofer/horn plastic PA cab, but it's not what I'd want for home theater.

DuraTex is no johnny-come-lately. I started using it after seeing it was used by Carvin on their pro-sound cabinets, which must have been 20 odd years ago. AFAIK I was the first to recommend it for the DIY community, it's since become a go-to source.

Why SLA Pro?
