I recently built two Fusion-6 Vibe speakers to extend my diy setup. I had great success building an SI18/iNuke configuration last fall, but my current project is not going as well. In short, The speakers sound like a giant midrange driver with muffled lows and highs.
I'm expecting to hear significant mid-bass producing sounds and high-hat sizzles from vocalists. The drivers have great reviews. Other owners testify they are able to produce vibrant and relatively full range sounds. No dance parties here. Michael Jackson sounds dull.
My AVR setup works great. For reference, I'm using a Yamaha RVX661 along with a set of Polk TSI200s. They play loud, have crisp highs and good mid-low end bass. For objective listening tests, I'm able to quickly change audio inputs between the vibes and the TSI200s using the AVR built-in a/b channels . I double checked by wiring and cross-over polarity and also unplugged the TSI200s while active to reuse the same output wiring and rule out any signal bias. All to no avail.
Maybe I expecting too much from this particular diy speaker? I can overlook some of bass output provided by the Polks two twin 5.25' woofers ported. But that doesn't explain the deficiency on the high-end. I keep reading about efficient this compression driver is.
I don't want to sound negative or unthankful, but the vibes sound no better than my Bose Acoustimass 7 (5.2). This can't surely be the case. Based on my reasoning, I must have defective speakers, crossover components or a crossover design that no longer applies to this particular speaker configuration. As the site says, the crossover component layout is relatively clean and straightforward. I was able to memorize the layout, in short order well before assembly. I also double checked the schema after soldering.
I certainly want to confirm the crossover design with another user. I emailed Erich for support, but not sure when he will respond. Due to copyright, I cannot publicly post or share it.
