And, I was surprised to find that when the monoblocks were in play, even lower volumes sounded more filled out.
sorry for the double posts, but I'm kind of a slow thinker.

B&W Matrix 800: Bi-amping thoughts?
One of these days I'll be able to unpack and set up the B&W Matrix 800's my pop left me. Our current home just isn't the place for them but we'll be taking care of that in the not too distant future.

Anyways, pop was using Jadis electronics with them and they were heavenly. However while the Defy7 at 100WPC worked well, I've been thinking bi-amping and powering the woofers with a SS amp of similar caliber and power instead. My thinking is to enjoy the air and musicality for mid's and tweeters that the tubes render but to have the bottom end punch and extension that SS seems to provide for those four 12" polymer woofers.
So my question is, what might be an appropriate SS amplifier for this set up?
The preamp will be a Jadis JP80 MC. Thanks much and...
Happy listening.

@knotscott You said: "From what I can find, the woofer crosses over to the midbass at around 300hz". Would you direct me to where you found that please? Thank you.
Happy listening. |
@musicfan2349 It was initially Meta AI. The B&W Matrix 800 speakers have separate crossovers housed in the three separate cabinets. Each woofer enclosure has a low-pass crossover dedicated to the driver inside, and the central cabinet houses the mid/high crossover boards. The crossover points are approximately at ¹:
It’s worth noting that some users have modified their B&W Matrix 800 speakers to use active crossovers, allowing for bi-amping. One option for this modification is the KBX crossover designed by Dan D’Agostino, which includes custom crossover points and a bass alignment filter ² ³." I found that Aurel Hifi as well as hifiwiki.com called them "transitional ranges" of 300hz and 3,000hz. https://hifi-wiki.com/index.php/B%26W_Matrix_800 I also saw another AI blurb on Google that stated 380hz and 3,000hz that referenced DIYAudio.com and Stereophile.

Wow lots of people to respond to! I appreciate your inputs. @knotscott Ah right, I’ve read that article. In fact I bookmarked it for the tweeter manufacturer in case I need to replace the OEM components. As they will have been silent for almost 30 years by the time I set them up, I’m desparately hoping the ferro fluid in the tweeters is still viable. And thank you for the info on the cross over points. Never having bi-amped anything before, don’t the amplifiers need to be of similar wattages? I’d thought about using the Defy7 for up top and the ML-335 for the woofers but would be concerned with the greater output from the ML-335 that it would over power the Defy7’s output. @68pete It’s been a couple of years since I took the system down and packed it for transport. And as I was limited on time, I didn’t make a good inventory of things like cables of which there was a dizzying array. I swear he kept every set of cables he ever bought. When I do unpack it all, it’s going to be like an audiophile’s Christmas for me! Happy listening.
