Woofer-Assisted Wide Band
@erik_squires i use assistant woofer and also assistant supertweeter in all my models bacheaudio to help wide band driver, Adding subwoofer is not help to cover 150 -350 hz. All wide diver and some woofers also got poor ability to reproduce this freg, I dont understand why so many audiophile like full range drivers , No punch, Thin sound |
mijostyn4,935 posts08-20-2021 12:47pmMiddle C is 256 Hz. 400 Hz is smack in the middle of the midrange. What you describe is a two way speaker. The only viable full range speaker that just needs a subwoofer is an ESL. Mozartfan, I am left speachless. ~~~~~~~~~~~~~~~~~ We could discuss this subject for,,well til the end of time.\ I am aware the commiment audiophiles possess (are possessed) by the woofer/midrange/tweeter,,or really if you look at Troels designs, most are midwoofers + tweeter. This concept will not work for my classical music. I need rich, complex, details, with a sensitivity greater than 91db IMHO woofers should be dedicated to voice the 30hz-say,,,200 hz range, well lets go 300hz. Thats it. I am not looking for a ~~midrange~ + woofer combination. The db sens is too low to do justice to the 300hz-say, 2khz range. at 87db-say 90db, Its not ~~quality mids. The driver is attempting to perform 2 tasks, same cycle, bass+ midrange. Seas and Scann speaks have made some incredible attempts at bridging these 2 feats all into 1 driver. But when you place a high quality wide band up next to a midwoofer,,,you will understand, as i understand the issues involved. Then we have the ~~Midrange~~ tweeter, = midtweet. Again, nice try, but no cigar. The tiny 3/4 inch dome tweet is making attempts to voice both mids and highs,,but in the end,,No Cigar. What everyone should do, is what I did,. Start buying wide bands, take out your tweet, and listen to how the new rick detailed mids come through. I am not looking for a wide band to carry anything other thahn say 100hz- 10khz. I can find woofers and tweets to voice the lows/highs. The W18's will stay to give a padding to kettle drums, bouble bass, low cello notes. I have them xossing at 1200ish..?? At 87db, and near field listening, you really dont get much bang. Anyway. I could never go back to midwofers/tweeter things. That is history. |

All wide diver and some woofers also got poor ability to reproduce this freg, I dont understand why so many audiophile like full range drivers , No punch, Thin sound ~~~~~~~~~~~~~~ I have not heard the AER's which from what I;'ve read , are the finest wide bands in production...But wayyyyy out my budget, So I'll never owna pair. The Voxativ AC1A's. were a **dud**. No bass, none, nada comming from the super thin papyrus paper cone. I wont even go into the midrange and highs comming from that driver. This design employs a series of neodymium magnets , like 8, placed along the motor. Perhaps the origi9nal magnet design is superior,. I have no idea. I am not interested. Again at $2300+++ a pair, I am not interested. I've found the DavidLouis wide band at very reasonable price and am quite happy what i am hearing I have another pair arriving next week. WE will see how that one performa snext to the 6.5 DL wide band. I am planing to run both, stacked. My speaker system will be a pair of 6.5's + 8's + The Thors. I really believe this will give me a classical orchestra experience that I've always been looking for. Its all about experiementation. But to answer your Q, sure the older designs, from Lowther, Fostex, had isssues. With these DavidLouis, I think some of these issues are dealt with. The lil 6.5 davidLouis (yellow cone) has OK bass, good clean mids, highs that do not roll off too early= a success. As I say I have the bass and highs already covered. I can see what Wilson was up to in their designs, packing the cabinet with all sorts of drivers. Trying to make the thing sound huge dynamic, full bodied, = Best Bang. Throwing a bunch of drivers in a cabinet is risky, somehwere there is going to be distortion, coloration which may result in listeners fatigue. I think Erik's OP offers the best option for acheiving full range/wide band fq's. The speaker's main driver is the wide band. With a woofer padding the lows, and a tweet padding the highs. The main dominate voice is from the wide band at a true 91+ db sensitivity. I am having spectacular results. AS it is, makes this speaker a winner. But there was another DL wide band that caught my attention, and we will see how this driver holds up against the 6.5's. |
Having owned and heard 2 of the worlds finest ever made tweeters Seas Millennium Seas Crescendo and the worlds finest ever made midwoofer Seas EXCEL W18E001 Based on this experience, I look at tweeters, midwoofers as ~~nothing more~~~ than helpers, supporters, offering augmentation for the wonder-full, incredible, fantastic, stunning ~~wide bands. That is to say, non-wide band drivers, really dont interest me in the least. Thats is to say, I'd never buy a Wilson, nor a Vandersteen. To me ears they all sound the same, fatiguing, when pushed to their limits. |
