I think going with the KEF LS50 is my best option. Is there a way I can add some crossover components to the LS50 OUTSIDE the enclosure? Not a dsp or Rca crossover. Id like to be able to power the whole setup with one amplifier. It looks all of these outboard crossover options will require two amplifiers.

While a passive crossover likely could be designed to roll off the KEF's and cross to the additional drivers, likely this will not be optimal, cost effective or keep the singular amplifier happy. ( load )


Your best chance for success is either a single amplifier module with two channels for each speaker, so two such amplifier modules ( 4 channels total ) with DSP integrated, or an outboard DSP unit with plural amplifiers.

Sounds like a job for a conjugate filter (if indeed necessary).

passive circuits interact. so if they have an unknown passive filter built in adding blindly in front of it is not a good approach. active and bi-amp is the easiest route to take.

Again, thank you guys for all of the help. Much appreciated.. I apologize for getting ahead of myself. I still have a lot to learn.

I think I’ll probably buy something like the Parasound P6 that has bass management and just build those cabinets for the 2 10” woofers. This might yield me some good results without too much stress. A good first project.

One of you suggested going with 8” drivers instead of 10”s. My goal has always been to have a coaxial that has a large sound and can reach down into the 20s with authority with a little EQing, but I think my max volume for the two woofers is about 2.75 cubic feet if I want to keep the appearance I am aiming at. Am I better off giving a pair of 8’s some extra room in that enclosure, or. since I am bi-amping and am going to be using a little bit of bass boost am I better off with the 10’s?

Just saw your thread. Im interested in chatting with you about the build. I have designed speakers commercially and as a hobbyist for decades...and I'm in New Jersey. Ive worked on several coaxial designs and have experience with 10" woofers. PM me if you wish and I'll forward my number.

"As I said, I have a very good idea of what I want to build. 6-1/2 coaxial in a sealed enclosure with 2 10inch woofers below it in a separate sealed enclosure."

In the Beginning...... the OP planned to use the 6.5" Tang Band W6-2313 coaxial speaker on top of two 10" woofers. A couple pic's for anyone following this thead for that first design... price range.

Recap: Building a sealed 2x10" cabinet to put underneath a pair of KEF LS50s.



So I was looking at the Parasound P6 and Emotiva XSP-1 because they have bass management, but the crossovers only go to 140hz and 250hz, respectively. Will this be high enough to crossover to the KEF LS50's?



If not I only see two other options, which is going with an outboard crossover like the Rolls SX45, or going with the passive Harrison Labs RCA crossovers that they sell on Parts Express. I could buy several different RCA crossovers and find one that works best.



Thoughts?

You can try the Mini-DSP 2x4 HD. Its a great development tool and totally flexible. Has Eq functionality which may be helpful for your 2x10 cabinets
