Yes, oops
As i remember now, I wanted to pass the link on to a biker friend at work, and I couldn't re-find it on here. At least I know where it is now !

I can't remember where I first saw this - apologies if it was on this forum !
I couldn't find it again until another search today.
Very amusing :

How was the sound in the room , Dave ?
Nick's phono showing well ?

Very good point by Chris there ! :idea: One of the main issues with getting bass to sound 'fast' or timing to be quick and crisp, is phase shift ie. group delay from the loading method. The age-old conundrum is that enclosures that give best bass extension from moderate-sized drivers also tend to be...

This kind of integration problem crops up with every really great driver unit. If you're running a ribbon, or a compression driver/horn for upper mids ; or ESL panels ; the big task is how to get the next driver down ( in freq ) to match up . It's the tonal/transient qualities that are really hard t...

Thanks for the spreadsheet , Scott. Have been running off a few examples today in gaps between work :D Charlie - been reading the blog a bit more - great work there , such a lot of detail goes into those ESLs, you must have put in some hours there ! The TL bass solution is inspired . It may just giv...

As Alex suggests, I'm very sceptical about those interstage specifications - even with bifilar winding ; not that anyone really needs 2mHz anyway !

Ooooh , those are interesting . Must be fairly local to you then ?
I wonder how the bass is done .... did you notice what sort of vent ( and where ) there was on the cabinets ?
Paul and Chris V would like the ion tweeter .

Hi Charlie - I've just started at : http://jazzman-esl-page.blogspot.co.uk/2007/01/speaker-cables.html - Can you tell us a little bit more about these speakers, especially ( for my purposes ) the TL section ? I've just started to explore the pages, but you could point us to the best postings a bit m...

I think there's a lot of useful experimentation to be done with cables. I just took the short cut and paid out a load of money about 2 years ago ... but for years I would have never thought I could go much further than the litz+cotton home-brew cables Bud Purvine made for me. I very much like those ...

Having looked at that design, simmed on Hornresp , and checked out also my first stab at a TL for the Audax PR240Z0 , I noticed something interesting . The WoofTl seems to use a very large start to vent area ratio, around 10:1 . This seems to extend the bass response lower - I could get to 20Hz with...

Sounds like what we all need ! I just realised the WoofTL you have is a TL, not a TQWT ! :) I was wondering..."howcome the vent is at the small end".. then it twigged ! There's is a clue in the name, of course. So, do you have the vent facing forward ? ( I've been struggling to find the pi...

I think we value oddness here on this forum, don't we Chris ?
Seems like a worthwhile question to ask for someone who is exploring the forum having landed recently .

Top notch ! I know Nick has been building a fair few of these , obviously for good reason .
