That´s why the Bliesma M142-6. I do not have the dome profile. Here is the comparison of the Bliesma Be-tweeter with an ideal tweeter (normalized to on-axis FR): Up to 8kHz the T25B-6 shows ideal piston-like behavior and above 8kHz there are only minor deviations. The T34 tweeter. Resulting loudspeaker sensitivity is dictated by the response of the woofer after baffle step. As a far comparison, the Audax TW034 is "ok", but it sounds like sandpaper on concrete compared to the Seas T35. Wishlist Compare CA$456. 5" in Ported Underseat Enclosures. Add to Wishlist . 83 - 8 Volt were carried out with High Pass Filter "on" (2nd order Butterworth type, 800 Hz cutoff, HPF2-800) The THD measurements at distance of 315 mm and. HighlightsWelcome to BlieSMa. This experience also led to use LR4 for Shamal project (22W Rev, MW16TX, T25B in WG) and yes, crossover is really. I would consider also tweeters with plastic, removable faceplate.

The transducers are the 15 inch Acoustic Elegance TD15H-8 as woofer, the 8 inch Acoustic Elegance TD8M-8 as lo-midrange, the 3 inch dome Bliesma M74B-6 as hi-midrange and the Bliesma T25B-6 1 inch dome tweeter. AudioTechnology 18H521706SD-4. . A dome midrange has 180 degrees dispersion at the crossover frequency. However, IMO the BlieSMa T25B-6 Beryillium tweeters are far better if you want the ultimate in detail and resolution. SS - 5,4g membrane weight. I'm looking to try something different. Remarks : Internal thread M3 (fixing tweeter) and M4 (fixing support Comet) are to be carried out by.
