For sale, a fantastic pair of Helicon 800's in piano cherry. They are in superb condition throughout. Grilles are perfect and the bi-wire links are installed. Rare speakers in even rarer condition.
Any demo welcome and I can possibly help with transport if needed (by arrangement) to keep them fresh. No boxes so it's strictly no 3rd party couriers for these.
The phone pictures don't do them justice. The cabinet finish is superb.
I think there is some confusion here. Times 1 is the benchmark time to write 150K Bytes of data to the disk. With improvements of CD Speed control, Laser Power and Sensitivity to light it possible to push the speed up to x52 etc. .Due to the age of the HHB recorders (which are very good) just basically buy CD-R's at the lowest speed (1 to 16) and dont pay a premium for high speed disks as the transport will not be able to make use of the faster CD-R.The writing software in the CD recorder sets the speed to a fixed value. (x1, X2 etc)
I do agree that pro-recorders can use standard computer disks, where as consumer machines require "Audio" which are formatted to designate they are audio, and in some countries carry extra tax for copyright reasons.
And yes you must run the finalize routine if you want to play the disks on a non-cd recorder.
Some CD players struggle with CD-R as the light coming back from the disk, is less than a pre-recorded CD.Sometimes a laser clean/replace and/or re-alignment can help.
Your speakers look awesome David, extremely professional!
Thank you for sharing although the embedded images aren't working for me.
The DIY examples collection is brilliant too!!!! It's a shame pinterest only let you see a section of the images if you don't have an account.
It is another compromise as I do love revealing speakers. I really thought a flat response at 1m was going to sound overly bright but it didn't, it sounded a touch bright in my room. I can't imagine that I'm gong to make many major improvements here given the length of time that my recent listening sessions have gone on for. I am desperate to get working on phase adjustments though. I can't wait to hear all the drivers properly aligned.
I'm a big believer in the benefits of correct alignment and speaker positioning although my recent toe-in change is producing bass imaging that I've simply never experienced before. In all the systems I've heard before (even stereo subs and large speakers) I've never been able to pin point where the bass is coming from. The best I've heard is when you can close your eyes and point in the rough direction where the bass is coming from, I assumed this was probably just from ques given by the higher frequencies. These are now producing what I'd consider pretty accurate stereo bass imaging.
On top of that; it would be pointless doing things like timing the drivers down to fractions of a millisecond if I were just going to plonk the speakers down somewhere that just sounds ok.
