Re: GM70 PP

You'll need a shipping crate twice the size for those Tannoys :-)

Re: yet another boring one trick pony turntable build

It is. But lessons like last night are good reminders to keep things in perspective! Interestingly I've just tried Logical Song and Dreamer on the Squeezebox from a ripped greatest hit cd. Logical Song is way better than the LP version I have. Way way better. Dreamer is on a par with Logical Song, m...

Re: yet another boring one trick pony turntable build

VPI something or other. Had it years but only just recently used it. Having tried wet cleaning in the past with disappointing results I like the vacuum as at least there isn't any crackle left from air drying. The dynamic range on the Supertramp album was quite an ear opener. We tried a few other al...

Riiiiiight, okay. I hadn't appreciated it was isobarik-like. This makes a lot more sense now.

Just to be clear.....the woofers are in phase accoustically, but out of phase electronically.
Can't quite get my head round this - what would be the practical difference? How is this done? Must be having end of the week brain fade.

Re: Ali Bastanis OB testing & results

I’ve seen on Vic’s Lencoheaven thread that there is no movement of the drivers’ baskets until he feeds them a 5hz tone. I can certainly vouch for there being no movement whilst I was listening- and some of that was at high SPL’s, certainly a fair bit higher than I would normally listen. With the dr...

I had to double check there, I thought that was Mark posting for a mo ;-)

Re: Ali Bastanis OB testing & results

It's a good question Ray. My gut feel was/is they would decouple the drivers from their supports - rigid supports will couple the drivers to whatever support arrangement more. Whether this is significant is another matter, but Vic's and Clive's experience perhaps suggests the lack of rigid coupling ...

Re: Ali Bastanis OB testing & results

Ah right, I'd entirely missed the suspension mechanism when I flicked through on my phone. Looking again on a computer it's far from trivial! A 3 wire cradle supported from two basket fixing holes and something around the magnet, suspended from above would probably be easiest, if there's enough sens...

Re: Ali Bastanis OB testing & results

Yes, I'm interested in the drivers being out of phase, and how that works without a lot of cancellation, but thought one step at a time. I get the equal weight distribution/simplified centre of gravity of a pair, but supporting a single driver should be a reasonably simple structural problem, especi...

Re: Ali Bastanis OB testing & results

In a small room I think a single UM18 will be fine. There is definitely something magical about the UM vs the RSS390 15" I was using before and feel a 1 x 18" UM18 would give a better result than 2 x 15" That's good news! But I need to reread the thread again as I thought much of the magic was from...

Re: Ali Bastanis OB testing & results

The benefit of the Behringers is the in built DSP I suppose, noting comments that Vic doesn't actually use any. Are there any decent, affordable standalone DSP options if required?

Are you thinking of more of the same 18"ers Ali, or swapping to the Daytons?
