Popular Post wgscott Posted August 5, 2018 Popular Post Share Posted August 5, 2018 Since this is CA, why not go all in on computer-controlled audio? Active full-range speakers like the top-of-the-line Dynaudio (or better options, if they exist), digital programmable crossovers, room/speaker correction to give a perfect room response, etc. Take the computer part of computer audio to its unapologetic extreme. It's your brand, after all! mitchco, jhwalker, esldude and 4 others 6 1 Link to comment

That would have been my suggestion as well. Go active. From your other comments I took it that you didn't want to go in that direction. Sal's suggestion is a good one, the JBL M2's. They have a dedicated amp, but can be used with other amps. It is a complete system however that includes their amp, their DSP, and speakers. Should one suggest a 5 channel system has some advantages since there is streaming of multi-channel recordings available? And always keep in mind: Cognitive biases, like seeing optical illusions are a sign of a normally functioning brain. We all have them, it’s nothing to be ashamed about, but it is something that affects our objective evaluation of reality. Link to comment

With their unique connection method directly from your amplifier, their there to extend those few low end Hz your speakers can't do. Essential just pressurizing your room. Whatever you choose for speakers will be great, this is just an add on feature to any speaker system. Plus, you know where to get them locally. If you want to borrow my subwoofer to try it out, your welcome to it. Good luck +1 Chris--your original post calls for full range speakers--it all depends on how you define "full". As Shawn suggests, I'm not sure there is such a thing without a sub. RELs are super, as are the new B&W DB series. Link to comment

Yes, Bill is right on the money. Really hard to beat an all in one active solution with on-board DSP. - the DSP is so good now it can control the overall directivity of the loudspeaker - typically a cardioid response to avoid the inevitable speaker boundary interference issues that we all face in our rooms. - modern waveguide technology to avoid the ever narrowing response in the top octave (10 kHz to 20 kHz) See link SBIR link above and scroll down to the "bookshelf" speaker response to show both speaker boundary interference patterns and narrowing HF directivity at 12 kHz. - linear phase response or time aligned, so that all direct sound arrives at ones ear at the same time. - response to 20 Hz in a small package - some would argue no sub required. - the on board ability to tune the tone to one's preferred frequency response. Here is a quick snapshot of one of those "all in one" speakers frequency and phase response measured in-room 1 meter away, with the back of the speaker close (40 cm) to the front wall: Full range response from 20 Hz to 24 kHz. Fat phase response down to my rooms standing wave at 31 Hz. No SBIR issues. These are largish bookshelf speakers on 24" stands. Analog and digital in, pro or consumer switchable sensitivity with simple room boundary and tone controls that are effective. Took me about 10 minutes to dial it in to my preferred tonal response using those two controls... Sounds as good as it measures ? Passive speakers won't be able to get by the SBIR, letalone the other benefits listed... PS Review coming on this speaker....

The Computer Audiophile Posted August 5, 2018 Author Share Posted August 5, 2018 Now I feel like I need two systems! i love DACs, but an active system with DSP makes a traditional DAC irrelevant. Given how many people still rely on traditional DACs there’s no way I can have a single active system and still write about external DACs. Ahhhhhhhh. First world problems. Would love it if I could find a way to do this. Hugo9000 1 Founder of Audiophile Style | My Audio Systems Link to comment
wgscott Posted August 5, 2018 Share Posted August 5, 2018 Sorry I don't have anything more specific to suggest, but if the commercial offerings for active speakers are a compromise, why not commission your favorite boutique speaker builder to make you something really innovative, i.e, better than the current state-of-the-art? I wonder if you could even have speakers with a push-button switch to allow you to toggle between passive and active crossovers? The Computer Audiophile 1 Link to comment

I suppose you could have a really fine active system as your main, and a very good headphone system as a secondary, which could be used for evaluating DACs.

Popular Post rando Posted August 6, 2018 Popular Post Share Posted August 6, 2018 I'll come out against an active system. You could replace it in Germany every year for the foreseeable future.

Given all the options available and the knowledge of members of the CA Community, I’m asking for help and opinions. I have an an idea what I want but I won’t say because I don’t want to steer the conversation. - I need a full range speaker - Compatible with a range of amplifiers - Dont get hung up on price when offering opinions. I'd honestly love to hear from as many people as possible and hear why they say what they say. Thanks in advance! Estelon .. oh wait, not compatible with any amplifier...

Interestingly, the published specs have been changed from 20hz at the low end to "only" 30hz. But the Kiis without the BXT have been measured as "full range". You do need the BTX if you want to play very loudly or to fill a large room. It also adds a significant amount to the maximum SPL output of the system. I'm sure dynamics for something like an orchestral piece are improved with the added bass module, and bass distortion at low frequencies/high output is surely reduced. Apparently the modules also further reduce various room interactions (ceiling and floor).
