Crescendo: Eureka! 100db from a 30L Cabinet - 65hz to 25khz

I also don't have a trained ear and know little about hifi except for hearing tunes from my Roksan Caspian integrated / Roksan floor standing speakers as a comparison. So how did it sound to me?

The Crescendos go loud. Very loud. The acoustic instruments sounded real and very lively. Regardless of which pre-amp it was paired with (I tried both the Tram2 and the TVC Django), there was good transparency and separation between the different sounds whether it be voice or instruments. There was something quite 'authentic' and 'real' about the sound. Once again, I don't know enough about high end systems to comment with authority, but I did like very much what I heard.

Lucky me - I live in HK and hence the DIY workshop is only 45 minutes drive away. I was disappointed I could only audition one speaker.. But even with one speaker I could hear good separation. I listened to Alison Krauss Live - very nice. Andrea Bocelli - for the first time I realized that his talent includes suddenly altering his voice an extra couple of db to extend it even further!

I don't think I can comment further unless I listen to those speakers again. Actually I was in the workshop to audition the Lux91 monos and Tram2 / Django rather than the speakers. I've since placed an order for the Lux and Django and they should be delivered next week! Can't wait. I just hope my existing Roksan floor standers don't compromise the ability of the pre-amp / power amp too much!

Hi HKL, welcome to the forum and I wish you many hours of pleasure with your system. Also I wish you get the chance to hear the stereo setup with crescendo speakers and report again.

Cheers

Hi there,

I have the luck to be in HK recently. I listened to the speakers and I am still very pleased with the sound I heard. The only issue for me is the cabinet, I do not like the current material and finish, it is not in line with the sound the speaker gives.

Is there someone who has an example of a nice cabinet with this speaker combination? It would be nice to get some inspiration.

The Cabinets are cheap prototype cabinets that where based on drawings that make it easy to DIY using minimal tools and wood pre-cut at large building markets etc. and paint finished.

There are no limits to ingenuity regarding the way the cabinets may be made and the materials they can be made from.

When my laptop was nicked a few weeks I lost the drawings I had made for a set of stone enclosure sets for the Crescendo Grande that where to be made from Indian "Black Galaxy Granite":



The basic design was borrowed somewhat from the YG Acoustics Kipod/Studio", but with more or less inverted colour scheme:



Now of course I have to re-do all the drawings.

Does anyone happen to have a recommendation for a very easy to use/learn drawing program that can produce 3D Renders with surface options, output 2D technical drawings with measurements and easily create exploded assembly drawings?

Cost?

It would likely be several 1000 Euro (still working on the pricing) plus shipping several 100Kg from Hong Kong. It is really only viable for local clients.

You can have a look around for a local shop in Toronto that works with stone.

I will make the plans available once everything done.

The top section will be basically precisely the Crescendo as per plans, the Woofer section will mainly be re-shaped. Oh and of course 25mm Stone instead of 18mm Plywood.

The woofer section can be shaped very freely as long net volume (without port) and port length and crossection are observed.

Hi,

Is there still a chance for the youtube video on crescendos in action?

Well, at least in DIY, the sky is the limit (and somewhat - your wallet) Set your imagination free!

Thorsten,

I think Google Sketchup: Google SketchUp
is easy enough to learn fast, but I don't know if it fulfills all your demands
Use tutorial videos... it saves time.

Best, Ivica

bump. just curious to see if anyone have built those?
I plan on building those later this year but would love to know what people thinks of the performance...

Goodness those ribbons are large!

I bet these are incredible sounding.
