Good luck.
Okay sounds good, I was just doing some quick math and it seems like an 8" x 11" crossover would take up most of the middle chamber in the 1099, where as most pictures I have seen the crossover doesnt take up much space at all. I am building the crossovers before I build the cabinets so I dont want to realize after I finish the crossovers that they dont fit.

Yes the board will take up a lot of the space in the mid section. But you could create 2 boards one for the woofs and another for the mid and high. I didn't go that route but it could be done. Also remember the mid chamber is a sealed section , so any holes you drill through for the wiring , will need to be sealed after wire is run though .Another thing is once your mid section is complete and the crossover board installed, you can fill poly over the crossover board.

If it was me(and was me last year)I would send Erich a message and change my order to the pre built crossovers.

I have 2 weeks to build the crossovers so I can figure something out.

Hey 1099 owners, what frequency is Audyssey crossing your 1099’s? Hopefully there are multiple replies so I can get an average. Thanks

I don't recall exactly but thinking it was 40 or 60hz. I bump them all to 80hz.

Audyssey sets my towers to 40Hz.

60hz, but my enclosure is slightly smaller which takes a little off the low end according to tux.

Mine were set to 40 Hz but I bumped them to 80.

Hi all,

Looking for some info and figured I'd post here vs creating a new thread.

Playing around a bit to figure out where to set the crossover for these. I'm crossing them to a pair midbass modules that are LPF'd at 150hz (an IB fills in below 60hz). Hoping to learn a bit about power handling on these as it relates to frequencies. Anyone able to shed some light on if raising the crossover above 80hz is recommended outside of just reading the response charts in REW?

For additional context, they currently have about 100w available to each for power. So nothing earth shattering.

With 100 watts, you won't hurt them regardless of crossover frequency (or even full range, but they won't sound great). Try different frequencies until you find what you think sounds best.

I have mine crossed at 120, but they're sitting on top of VBSS subs that are more than capable of providing that midbass slam.

Yep, I'm not worried about hurting them. I'm more interested in learning about how the crossover frequency will affect the wattage they require fro high SPL levels. I assume if I have them crossed lower, it'll take more power and therefore I'll lose some clarity/dynamics given that I only have ~100w to them. (I should note I'm well aware they play damn loud with 100w, but just looking for additional understanding and clarity). I'm not familiar with these Eminence woofers to know where they require the most power in the frequency range given the port tuning.

I'm just curious to know if anyone is able to shed some light on that @tuxedocivic , is this something you can answer?
