The Accutons have very wide dispersion which makes it pointless in most situations to optimize the on-axis sound at the cost of the off-axis sound. I went with a Butterworth crossover, because it produces a "flat total power" output response rather than the L-R "flat on-axis" response. The other aspect to consider is the type of crossover. Ie: I made it totally flat and accurate and for some it's still too bright. This is after I used an L-pad that muted the tweeter by a few dB to compensate for driver sensitivity, impedance, and parasitic coil resistance in the woofer's crossover section. The Accutons have wide dispersion, so consequently people are hearing a lot more treble than they're used to. They're used to silk dome tweeters that project their limited 91dB/W output in a narrow spotlight-beam straight ahead and a lot of music is mixed with such speakers in mind. Some people can never get used to the sound of my C23 tweeters. If I had made active 4th-order crossovers with notch filters, that would be even better IMO. Cone breakup isn't actually bad at all, especially as I made the crossover 3rd-order at 2.75kHz. The same goes for enclosures.Ĭlick to expand. But remember, expensive capacitors and inductors a good crossover do not make design made well and chosen parts for wise reasons do a good crossover make. You'll need to design the crossovers and enclosures to much higher standards than is necessary with most speakers. What are your past diy experiences? I made a 2.1-way system with the C23 and the C94 speakers, and that was tough work. That way the monitors can be kept down to a reasonable size without too many sacrifices. Just an idea: for a small room you might want a mono "centre woofer" for the bass: crossed over at ~300Hz and playing down to whatever low frequency it can handle. Its frequency response goes low enough to be able to use a large-ish woofer for all of the bass, rather than a premium midwoofer + subwoofer. When I make my next pair of speakers (I keep saying that I will, but I'll get around to it one day), I intend to use the C79 for the midrange. Looking at the specs, the C44 is practically a second tweeter rather than a midrange. ![]()
