I started another thread earlier discussing my efforts to design proportional-looking columns to house the HT-8. My problem was that the supplied SEOS waveguide (10") forced a wider than appealing column width. Dejected, I began to consider the Volt 8's as a possible replacement, but not without some pain given the general consensus that the HT-8 are simply a better surround speaker than the Volt's After the post, I began wondering at the various sizes of the SEOS waveguide and found a smaller version at the DIYSG website: https://www.diysoundgroup.com/seos-8-tweeter.html I am not a speaker designer, but I am wondering how the HT-8 response would be affected if I swapped the SEOS 10 for a SEOS 8...? If the performance is in the ballpark (still better than the Volt 8's) I could build a narrower box and have genuine love for my svelte theater columns! Thanks !
