Desert Noises Posted December 7, 2021 Share Posted December 7, 2021 I have a 1988 pair of La Scalas with two problems I'm trying to solve:boxy/stuffy bass and harsh midrange. Here's how they are configured: Type A/4500 crossovers from Crites CT120 Tweeters from Crites Stock K-401 mid horn with the A-55-G drivers Stock K-33-E woofers (also tried the Eminence Kappa 15C) Room size is 16'x20' with high vaulted ceiling, floor carpeted, with La Scalas in corners along the 16' wall, toed in approx 20 deg. SVS SB2000 sub crossed at 80 Hz near the right speaker Amplification is from a fully restored/recapped Pioneer SX-1250 DAC for digital music is a Schiit Modi Uber Turntable is Kenwood KD-750 with Audio-Technica VM540ML cartridge My woes with the La Scalas are as follows: 1) The upper bass sounds boxy, nasal-y and stuffy. 2) The midrange at higher volume (~90 dB) is just plain harsh and unpleasant. I reduce the 100 Hz tone control a bit and that alleviates the boxy/stuffiness to a degree. Meanwhile, I connect my home-built Cornwalls (Clonewalls) with B2 crossovers, K-55 mid, K-77 tweet, and Kappa 15C, and they sound amazing with no fatigue, even at higher volumes. Plus I get bass! Classical music commands a lifelike presence. I used to love the La Scalas before my recently built Cornwalls. Now that I can compare between the two, I vastly prefer the sound of the Cornwall. Am I missing something, or has anyone else had the same experience? I've been considering dropping the mid down 3 dB and changing the capacitor to 6.8 uF. Is there anything else I can try short of doing anything drastic like cutting wood? 1 Quote Link to comment Share on other sites More sharing options...
