Aerial 10t bases w/ B&W 705 uppers - Mismatched, Advise Needed

Hey guys,

I just got a set of Aerial 10t bases(uppers were lost) and a set of B&W 705 speakers that I want to use as uppers. What is the best way to wire them together? Can I expect to have good results with them wired in parallel via front L and R power amp outs? Or should I try to run everything into the 10T and use the upper out terminals to power the B&Ws? The Aerial cabs have a crossover circuit inside that can feed the uppers. Im just looking for any experience or suggestions at this point before I make my first pass at wiring them up for a test drive!

Thanks :)

I am glad you're trying to keep these, didn't I see these for sale??

I would think you're fine using the Aerial crossover circuit, tho I am sure others will chime in.

I was trying to sell them for a friend but we were able to work out a trade so I ended up with them. Im super excited to have them.
 
Here are the terminal out connections for the uppers. Any idea what connector this uses? Pics attached.

They are banana connectors, one for the midrange and one for the tweeter. I don’t know which is which though.
 
If you are going to use the Aerial’s x-over, won’t you need to eliminate the x-over in the B&Ws?
 
Without knowing the nominal impedance of each section in addition to the crossover points you're wasting your time. The chances of the two sections matching are extremely slim to non-existent.

I went ahead and just wired the uppers and lowers in parallel it sounds pretty amazing so I think Ill run it like this for a while.

I like it, nice, simple fix.

F1nut does speak true, tho. I'm thinking that some of the gurus here might be able to help you with a crossover modification that would make these play together even better.

Glad you're enjoying them !!
 
How were the 10t Heads wired to the bass towers? Was there a connection at the top, or did a cable extend from those double banana jacks? More curious than anything. But, I'd also try using the internal Aerial crossover. That would provide a high pass connection to the B&W's, which would limit the amount of bass the B&W's see. It could clean up the midrange performance. Especially, if you like to crank a bit? And if the balance of the 2 speakers sounds good at present, using a high pass connection shouldn't hurt anything.

I do wonder though, do you know what happened to the Aerial uppers? I hope it's not a sad story...! :eek::(

No clue what happened to the uppers. They got disposed of or lost at some point. There used to be a pigtail of sorts I presume. I may attempt to bi-amp these and I can put an HPF on the uppers in the preamp stage. Then Ill drive the lowers with another channel.
 
Feel free to call the guys at Aerial and ask for advice. They are right around the corner from me in Wilmington, MA. They all came from ADS/Braun and have a HUGE wealth of knowledge on speaker design. Nice guys.
 
So last night I ran a dedicated speaker cable for the lowers and Ive got my receiver in bi-amp stereo mode with the lowers and uppers on separate power amp outs and there is an 80hz crossover as well which is configurable in 20hz increments up or down. It sounds much more balanced now. Definitely a big improvement over running them off one channel.

Awesome. That's probably the best you can hope for, considering the Franken-Speaker nature of the set up. Well done. :thumbsup:

You cannot bi-amp with an AVR, period.

Bi-amping involves 2 separate amplifiers meaning completely separate power supplies not a shared supply. In addition and extremely important it requires the use of active crossovers. Anything else isn't bi-amping.

I don't think he said anything about an AVR. :idea:

And you can bi-amp using passive crossovers, it's called passive biamping.

What else would it be!?!

It's still not real bi-amping.

F1nut, Im using a Pioneer VSX-50 AVR. They have what they call a bi-amp mode which supports two sets of cables for the fronts and a configurable crossover. Maybe its not real bi-amping since I assume its the same power amp unless there is more than one in the device. Perhaps its just a separate preamp stage more than anything else. None the less it sounds way better than running them in parallel on the same stereo power amp out. I think the crossover helps a lot.
