For EQ they do, for time alignment, not at at all IMO. They will time delay to mic placement position. Which will try to get the center of the stage right in front of your face. An RTA and a good set of ears is the best starting point. I'm big on using an RTA to get a baseline to fine tune off of.

For time alignment it's almost voodoo science in a car as every cars shape and materials and speaker placement all play roles. If you're using a 2 way setup with passive crossovers with the woofers in the doors and tweeters in the a-pillars, you can't do all that much in terms of fine tuning T/A.

Some good points.

'Warm sound' as I have heard refered too many times, such as tube driver amplifiers also could be focusing more on the tonals of midrange, being a broad spectrum. I think the JVC wood cones would definately have a hard time reproducing the string tones though they could be more subtle.

I am trying to focus on realism in this thread.

I have no experiance with tube driver amplifiers or time alignment. Sound reflection and absorbtion in the automobile interior are subtle factors no doubt. Neither do I have experiance with time alignment, though speaker placement is certainly a factor.

Thanks for the comments...

Putting it all together and making it work funtionally takes some practise and work and sharing of thought.

^ Agreed. 'Warm' generally is synonymous with 'no highs'

Mohawk, have u heard the JVC woodcone system? They were designed for accurate reproduction of acoustic instruments and vocals. Why are most instruments are still made out of wood instead of synthetics? I would guess their tonal qualities and resonance. When manufacturing, the original test and tune was with a violinist that played a track and then had her input as to the realism of the sound.

I haven't heard the automotive version, but if anything like the home audio version they would be fantastic. The woodcones went into production after over 20 years of R&D. I'd guess they didnt want to put out anything less than "perfect". For the right listener anyway.

I have not...

HOWEVER.... Most instruments being made of wood offer their own resonant characteristics to the sound of the strings. Something captured in the recording itself (hopefully). Wood speakers would then add their own resonances to the recording. Not to mention that wood is extremely inconsistent in strength from tree to tree, relative humidity etc. I'm going to call Esoteric Gimmick on this one

Mr.DatSubishi

^I doubt a company would waste 20 years and a whole lot of money in man hours and tooling on a gimmick. They are particular about the wood they choose, grain pattern etc and each speaker does sound slightly different. That's why they're tuned as a pair before packing. The wood is treated after pressing to maintain a consistent sound over the years. Find any info u can through reviews, personal use and see what people have to say.

Our company has sold many of these sets the the Victoria Symphony and their members say these are the most realistic sounding speakers for what they do. Again, personal preference and music style come into play, but most of these people have been playing instruments their whole lives and probably have a pretty good grasp on what they should sound like.

Not to beat a dead horse. but how can something so inconsistent be so natural?. I can understand slight variances, but wood as a whole is far too inconsistent. I've heard a great deal many of "the best new thing you'll ever hear" materials and technologies over the years. Best overall as far as midrange or full range drivers go seems to consitantly always be paper or wood pulp. I'm with you on the wood here... just not unprocessed grainy wood.

No I cannot really let this go... vinyl has a much poorer frequency response, CD's do a better job at the frequency extremes and also tend to be much more linear. The performance will vary from each pressing to the next, and on the quality of the vinyl it is pressed on. The performance will also vary due to the mechanical to electrical interface (the stylus does add quite a bit of variation to the performance) and dont forget the phono amplification stage can be a source of distortion too (my Krell sounds a little thin/ minimalist while my CJ sounded full an rich).

Having said all of that I have often found that records can get me awfully close to the musical event... but so can a CD

Mr.DatSubishi

Recordings on vinyl can range any where between 8hz to 30khz. That's pretty broad. Yes, there is a lot of rumble in the low end and some equipment will not do super high frequencies. But they can. There is different variables in home theatre equipment as in car. And you can pay $100 for a turntable and accessories. Or you could pay $10,000. Which is gonna sound better?

JohnVroom

... your not letting the reality of the record playing experience alter your theory eh? those low frequencies are probably not music but rumble (I have had LF vinyl and the SIZE of the track on the record is amazing and most of my cartridges wouldn't track it and I couldn't hear it (LF roll-off of my speakers and my ears)) as for the 30K responce I dont recall a manufacturer of a phono cartridge ever calling THAT out, I am pretty sure the mold for the vinyl cant be done that accurately. I would add a record IS capable of a lot of memory storage the weak links are pressing of the record (and shipping and storing as all could cause the warping I have on so many mass produced albums), accurate table speed, the cartridge and the interconnect to the preamp. I dont think $ is an accurate measurement of performance, it is an indicator but as someone who is not afraid to spend stupid money for items I listen first and then price after the fact assured in the knowledge I got the best bargain because I purchased the best product


I guess I should find some time and get ahold of MoFi and see what their tech says eh? My info is predominantly second hand so..
