Hi Everyone,
I have questions regarding the next project I'd like to undertake, and I'm hoping you all can shed some light on them. I want to design a 5.1 HT setup for my living room to replace the Aperion Audio Intimus 5T towers and 5C center channel that I have currently. There's nothing inherently wrong with these speakers, except that I didn't build them! Of course, I can't resist the urge to make these dual purpose and make sure the L and R towers can sing in 2 channel stereo listening too!
My early questions are around arrangements of drivers and choices of driver sensitivity. My goal is to have > 90 dB of system sensitivity for these towers, and I'd like to use a MTMWW array to accomplish this (with a matching MTM... or WMTMW arranged center channel for the dialogue/home theater aspect). Assumed baffle width is 7 or 8 inches at this point. Looking for a modest size system that won't overwhelm the living room when non-speaker savvy friends / family visit!
The biggest point of confusion is this. How should I arrange my driver sensitivities for the easiest XO design and baffle step compensation? Based on early research, I should aim for the WW section to have around 3 dB of efficiency more than my mid and tweeter. The logic here being that baffle step losses will "pad" the bass response down to match the mids and highs better, resulting in LESS required padding on the mids and highs to reach an even response. Does that make sense?
I've gone through a preliminary round of sensitivity studies with the RS series of drivers from Dayton Audio. I looked at various combinations of 4 ohm series and 8 ohm parallel for the woofer and mid sections. The tweeter section is generally settled, as I picked up 3 of the newly released RST28F tweeters that I'd like to use. My general selection matrix is attached below. I am not 100% committed to using the RS drivers only, but these were the easiest entry point to the thought exercise. I also like some of the SB acoustics stuff available elsewhere, and some of the Tang Band W4 drivers available from Parts Express for mids.
So... how would you guys choose the starting sensitivity ranges for your 3-way tower designs? Am I on the right track by choosing a more efficient woofer section and counting on baffle step from a ~7-8 inch wide baffle to knock me down a few dB?
Thanks!
Keith
