How loud do you want to play music? Do you want to go over about 90dB?
Can we get a closeup of the woofer where it is recessed into the box? Do you want to have the grills off on occasion? I would. If you do, I think both drivers should be identical, even if you make one a midrange.
I'm sure it's a 2.5 way.
Yeah they're nice, they have a really good WAF to my surprize as I thought they would be 'too big'. We A/B'd them to the PSB we normally have and both agreed that the Advent were lacking. I've moved these Advent to our music area and the PSB to the HT so I could get that hooked up. I was listening again to the Advent last night, and was thinking the same thing as you about a xover.
When we did a critical listening with music, I thought the PSB were rich and balanced, just about perfect overall except for a small lack of low end. The Advent seemed thinner by comparison, and had a hasher midrange especially in the vocals and electric guitars. I've heard people say these Advents "actually have a pretty good tweeter". The Advent actually sound pretty good in the HT, but I think its becaused of the pronounced mids.
Last night we were playing Wii, and I noticed that they were very clear overall, had a nice bottom end at times (but could/should be vastly improved for 8" big cabs) though the content was lacking there, and the tweeter really were very nice. If the cab was ported, and the mids could be changed via crossover, cabinet braced, etc it could make a huge difference. That said, I'm not sure if the lows and mids could be fixed without a driver change.
-Yes I have the grills off now and prefer it, although i'm not thrilled about the rather large grill guide cups. I would also prefer both drivers to be the same just for aesthetics alone.
-Not sure if I could make any kid of schematic, I can barely read one myself without much pain and research. LOL I took that closeup pic, and can supply more and try to read whats on everything.
-I can take any pics that would be helpful. I'll take out the driver and take some of the driver and the inside of the cab as well as the driver recess.
-I don't have a great sense of what 90dB is, but we don't really listen to this stereo very loud. When we do it's more for room filling rather than cranking if that makes sense. Loudest it would ever go is where you'd have to talk very loud for someone to hear you. My truck stereo is the cranker. I've got Morel MDT 12>Vifa TG>Dayton RS180 and an Illusion Audio reverse voice coil (extremely shallow) carbon fiber 12" sub. Each driver has a separate channel from two Helix amps with built-in xovers. All in a tiny mid-sized CREWcab truck. It has the massive limitations of a vehicle environment, but even without having my dash pods done yet, it has been so good as to give me that audiogeek warm fuzzy.
