They will sound fine passively with the Avondale’s; I started off with an original set of M130 monoblocks 16 years ago.
Thanks for the extra info. I had someone else tell me privately that the Hiquphon's I would need were the OW4, so if I go this route I'll have to double check all that.Hi Mike,
From the POV of being fully clued up before making a decision, the tweeters will be Hiquphon OW1-92 (92mm to fit the Linn cutout) and circa $US 290. a pair.
Also, DMS with single XLR sockets will have 2 x 3-way crossovers within each enclosure, with these mounted on the sidewalls within the isobaric enclosure between the KEF B139 bass drivers. Each PCB has 6 x axial caps, any number of which may have gone off by now.
Another thing worth considering is that although these were spec'd at 88lb, they feel more like 120. (you are not getting any younger, you know ).
It looks like the OW4 is higher sensitivity, which affect the crossover circuit. If the OW1 is considered to be the correct match, then I would go with that.All the hyquphon tweeters are basically the same, the difference between them is the coating used.
OW1 is the nearest stock but you may prefer one of the others.
I hadn't paid much attention to the age of the cross-over components. That's certainly a concern, making it more likely that I would have to go active.
They're a bit more expensive than that, and likely needing tweeters. There's a difference, though: Here in Canada they don't come up very often, so I'm less hopeful that a better pair will appear tomorrow for less money.given that your 2 tweeters are going to cost over £300 you need to define "paltry " if they are close to £700 then I would give them a miss as you can get a good pair for under £1000. If they are very cheap then there is no better way to experience a wall of sound with bass that goes subsonic. I have experienced organ recitals with fundamentals lower than 20Hz ( only on vinyl ) on a pair and it was like being in a room with a jet engine but no sound, I've never heard true bass like bricks with any other speaker that I have listened to and they were passive.
I had 2 pairs and it is difficult to have more fun for as little money these days.
Each amp channel has at least a 400VA transformer, so lots of juice.What power supply do you plan to use with the NCC300?
Thanks for the dissenting view. I hear what you're saying. What I have now sounds very realistic, but it doesn't sound BIG. I guess I'm yearning for a hyperbolic, larger-than-life experience.Should I Buy These Isobariks?
I say no.
My best mate has a mint pair.
He’s spent a load of time and money getting them right - and drives them with a fortune’s worth of late model NAIM gear.
They have their own sound, which some enjoy.
My view is that the design is way too convoluted to deliver truly coherent and palpable replay.
The big LINNs don’t sound terrible, but less complex speaker designs with simple crossovers seem to deliver far more realistic sound, to my ears.
Just one opinion. Sorry to be a detractor, but you asked the question.
