Here is an update on the Sony speaker project. A few days ago the receiver was being run at high volume when I noticed distortion in the high end. After playing with the volume a while it was obvious the little mylar dome tweeter can not handle the extra watts the new crossovers throws at it ( crossover went from about 16,000 hz to 3000 hz). So while it sounds fine at normal volume, cranking it up causes the tweeter to fail long before the 5.25" woofer.
So, time to upgrade the tweeter. Need one that will fit in the same footprint of the Sony tweeter (about 2.75 " diameter) because real estate on the front of the speaker enclosure is limited. The tweeter needs to handle maybe 30 or 40 watts and I want one that has a nice flat frequency response. Also, I don't want to spend too much (remember these Sonys only cost $55/pair new). Lots of reading and searches led me to the usual brands like HiVi, Dayton and Goldwood. Then I found the Tang Band 25-302SH 1" FABRIC DOME / NEODYMIUM Tweeters that have a fantastic frequency range and flat as a pancake too!
These typically sell for $22 a piece, but I was able to find a site that sells a pair for $25!
These will be coming this week, and I can't wait to get them installed.
So far, the speaker project expense sheet is as follows for one speaker:
- Sony SSB1000 ($55.00 a pair) $27.50 each
- Infinity Crossover $4.75 each (ebay)
- Acoustic Foam $0.00 (free - already had from another project)
- Tang Band Tweeter $12.50 eachTotal each speaker $44.75
Hope they sound good, the TB tweeter got good reviews. Besides, what can you get for $44.75 a piece that sounds OK?
The small (6 11/16 x 10 1/16 x 7 1/16") MDF cabinet, (about 1/6th cu/ft, is probably worth the initial investment alone! LOL!
I know what will happen next... I will find fault with the 5.25" HOP woofer and start looking for a better replacement.
