Let me clarify, I am currently using the stock Ascend Acoustics Sierra-1's. Sometime in the next couple of months, Dave is going to upgrade the tweeters to the RAAL and modify the crossover to work with that particular tweeter, BUT, that is irrelevant! The little 5.25 woofer may indeed go down to 50hz but I want to make the front mains, LCR's, full range instead of dropping off at 50hz to 60hz. Even if they go down lower, they do not have much output at all, plus the mid-bass is weak. I want to make the front end have a full sound that is capable of doing 40hz to 60hz and up with some decent output and to fill in the gaps below. I will also likely convert these to running active or quasi-active at some point during this.
Right now I am thinking about using either the JBL 2226j or various woofers from the likes of B&C or Dayton. I can get the JBL-2226j for under $150 bucks each, not sure about the Daytons or B&C. And yes, I want to make these sound as good as a capable 3-way. I do not want to run my existing subs to 100hz or above, what I want to do is have them cover only around 60hz and below, then use these new woofers to cover the upper end of the low frequencys and the lower end of the mid-bass.
Any suggestions on woofers, enclosure, crossovers, ect...would be greatly appreciated!
P.S.- I need the most help with figuring out the best way to implement this setup. I am probably going to go active with this and use a 10 x 10 advanced plug-in MiniDsp, but would definitely consider other options. I have a several amps laying around. (ie Behringer EP4,000, (3 x )Behringer EP1,500, Peavey IPR, (2 x) Adcom GFA-545, and a couple of older Parasound amps, not sure of the models.
