Hello everyone,
I've completed the crossover upgrade for all three speakers (SVS Ultra center and bookshelf speakers). Is the upgrade worth the effort? Absolutely! My results, of course at this point, are anecdotal based on a couple hours of listening. Yesterday, I had the center and right bookshelf completed. I listened to a variety of very familiar SACD classical & heavy bass jazz (multi 5.0) music. I was impressed with the vocals from the center and right compared to the left channel. Today, all three speakers are completed and listened to the same music. Vocals, again, are the standout improvement, which is great for me, as I listen to a lot of chorus and soloist music. Interestingly, and completely unexplainable, I had to reduce both of my subwoofers 2db (Audyssey is OFF, maybe that's why). What next? Run Audyssey (using the app) tomorrow morning while everyone is asleep. After a few days of "burn in", run REW.
What's involved?
Danny has a lot of videos on his YouTube channel going over every aspect of speaker work.
1. Install no-rez to limit cabinet resonance. Toughest aspect is cutting the stuff. If you have a workshop with a bandsaw, you are in better shape than me.
2. Cut wood to hold the crossovers.
3. Lay out the crossover parts per the diagram (this took some thinking but I eventually got it). You can email a photo of the completed crossover to Danny for his approval.
4. Drill holes in wood and to use zip ties to hold parts on to board.
5. Measure, cut & strip positive and negative wires.
6. Wire everything together.
7. Start soldering! Don't forget heat shrink.
8. Install crossover in to speaker cabinets.
9. Use polyfill or insulation inside cabinets.
10. Solder wires to speakers and rear tube connectors (will accommodate banana plugs).
The work is not difficult but tedious and time consuming. If your hands are old like mine, they may cramp up. Bottom line for me: I'm retired now so I had the time. I can't afford new speakers, for instance the Concept 500 at $6K a pair or Danny's open baffle speakers at $3K a pair. The entire SVS Ultra system is $2,500 (including the surrounds). Reviews of the speakers are very positive, but we all realize that they are a $2,500 speaker system. I've been very happy with the SVS system up until now (about 6 or 7 years). The upgrade made complete sense to me. Breath new life in to my speaker system. Several months ago, I completed the SVS amplifier upgrade for my SB 13 Ultra subwoofers. That was a great upgrade too. So now, I'm set (until my hearing goes out, LOL). Oh yeah, my wife is very happy I am finally done with all these upgrades.
Once I complete burn in, Audyssey, REW, and lots more listening, I'll add additional thoughts.
