WILL THE NEW 60,000 AVALON ISIS BE THE BEST YET?

Or you can buy Accuton based kits from the likes of W.A.R.

Using a kit would be a pre-requisite first step, for anyone wishing to build an Accuton based speaker (unless one is very experienced. I, for one, am not).
They are very difficult drivers and designing a system from scratch (even with the help of a dsp) would be extremely difficult IMO.
And expensive, too. At the price level of Accuton, one may find happiness with the likes of Supravox, Phy, Lowther, Fostex... (many others)

U do have a pt Jtgofish. If I knew how and do it well at that, then yes your'e right. But the problems is most of us and certainly I do not have ability to what you are suggesting.

Buy a kit based on a tried design by a confirmed engineer (often the same engineers who design spkrs for commercial manufacturers). You'll get the mechanical design for the cabinet, the electronic parts, matls... Spend a WE assembling it -- and you'll nejoy yourself immensely!

Getting back to thw ISIS,for a moment,as I just spoke to the folks at Avalon,it seems that the ISIS is a ported design.Though I'm sure it IS superb,the porting(regardless of mfgr claims)is NOT as accurate in the midbass and bass as a sealed enclosure.I have never heard a ported box that did not have a signature sound.I have heard ALL contenders,like the big JM Labs,biggest NOLA Exotica(deep bass,discontinuous),Wilsons etc.If you have heard a really great sealed enclosure you know what I mean(provided it does the rest of the musical spectrum well).

I have a friend who has held onto his old Infinity RS-1b's,and "mega modded" them.These are sealed box speakers,and when you hear the pitch definition in the lower octaves,that they possess,you are simply bowled over.I really believe,due to the shift in the speaker design industry,to ports which satisfy the average consumer,that it will be an educational experience for any of us to hear a great sealed box design.Sorry for the run-on sentence!

BTW-If I ever own the ISIS,Id happily rationalize these comments!!

Best!

I want to confirm Sirspeedy about adding subwoofer to Avalon speakers. It is an awesome system. I use Avalon Avatar with Martin Logan Depth sub-woofer. It takes me year to make them seamless blend together. But when you achieve this stage, you got big reward. One key is to use inconnection cable of subwoofer as same quality as your main interconnection cable. Most people just use inferior interconnection cable because it is for subwoofer, it is not full bandwidth. I went to listen to Avalon Indra. I still prefer my Avalon Avatar with subwoofer. The mid base is died for. However when I listened to Avalon Eidolon Diamond. It is different story. It made me paid deposit to dealer at those day. Now I'm waiting for Eidolon Diamonds to be delivered to my house and be played with my system.
