Would you mind expanding on that a little? Like what type of horn/driver you're using, and what you're looking to improve by going 3-way. Are you keeping the horns?

And I'm interested in the how well the B&C's handled midrange detail.


I had the 6ndl38's crossed from 80hz-1.6k initially with Bms 4540nd drivers on a set of ID mini horn bodies. I then swapped the 4540's for a pair of 4552nd's and dropped the mid/horn xo down to 1k.

Detail of the B&C's wasn't bad. They're a bit on the warm side of things. They'll play up to about 3k without any major problems but I preferred to keep them at 1k or below since they seemed to lose a bit of detail crossed over higher.

Still going to use the horns in the current install. I'll be using a set of ID full size bodies with the same 4552nd drivers although I may switch back to the mini bodies since they seemed to sound a bit better unless I can find a pair of straight entry illusion or veritas bodies. My main goals for going 3-way this time is to have more midbass output and a little more output capability overall. I'll be using a set of B&C 8ndl51's for midbass duties.

when I asked a shop owner I know, he was willing to sell me a bnew pair of the 6.5's for approx US$122. not sure about the exact SRP.

I heard a friend's car having two of those in each door and they do play loud and sound good. don't know how much EQ'ing he did but he didn't use an outboard processor. just an Alpine full active capable HU then to the amps. although I think you would need an 8" for those to blend nicely to most car subs. They can blend OK without a midbass but I prefer them with midbasses.

Thanks for the input guys. It will be a little while before I can persue this experiment, and it will be fairly low-budget.

I can get what I want out of lower efficiency drivers I already have. But, I'm bored and want to experiment with stuff i've overlooked in the past. This will probably be an exercise in driver mods and getting the most out of inexpensive drivers.

Any further suggestions are appreciated.


djQ, those Powerbass still look good. Midbass is not an issue, as i have several 6-7-8" woofers to choose from already in the shop . The mid/tweets will be evaluated by themselves first.



ca90, thanks for the details. I'll eventually be going 3-way, too. But for now, I just want to evaluate the horn option as opposed to a two-way on the dash instead. The horns will need to go down to about 1kHz to merit the change. At least, I think so. And your compression drivers are better than mine!



tinitus, the difference between the Eminence A/C is the impedance. Simply by price default, they may win. I was hoping for more choices, but the budget is getting contsricted.
The Eighteensound that you and ca90ss suggested look nice, I have no idea what they cost yet.

If anyone is interested, I'll post the subjective results of my foolishness when it happens.

The Eighteen Sound drivers are probably a bit more than the B&C's and will be a little harder to find.

Fwiw this guy used the Eminence Alpha's and seemed to like them.

US Speaker, 129USD fore the 18sound

The thing I like about the Beta8 is that the new model has the dustcap from the popular Alpha6, and cone looks very much like whats used in a couple of both 18sound and B&C, and ofcourse the good sensitivity...havent heard them though

About difference of Alpha-6A and 6C
Well, its surely much more than just impedance
Totally different response curves
All specs are slightly different too
Alpha-6C is a much later model, so probably improved, but not seen in EU yet
