Given the large volume of your overall room, I think subs could be helpful. But also, have you tested to make sure that the roofers were not wired out of phase on your speakers? Since the problem occurred in your old room, and this room, it was carried over with the system. there is a test you can do with a 9 V battery which you hook up to the speaker leads, and feel which way the woofer moves, inward or outward. It should be the same on both speakers if you wire at the same way. You might need to research this test.
Help. System sounds thin and bright or harsh
Hope this isn't redundant tried to post in Tech Talk
Just moved my system to a new home/sound room and it still sounds harsh and a bit thin despite supposedly "warm" sounding Harbeth 30.1 speakers. This issue is not new and I had put the blame on the old listening room. Can't figure out what the problem is. I listen loud at 80dcbl or higher and sit nearfield about 8 feet from the speaker plane. (sound is thin and bright from afar as well) I have experimented in both homes with speaker placement, toe-in and the like. Speakers are placed a lil over 3 feet from the rear wall and about two and a half feet from side walls. I feel something is off. Perhaps a component or two that is known to be tipped up in the highs and a lil bass shy?? Also, I leave all solid state components fully powered up 24/7. (not the tubes)
System:
Modwright/Oppo BDP 105 disc player (all mods with tubed power supply and pricey NOS tube upgrades throughout) Looking to replace once the harshness/bright issue is nailed down.
Parasound JC2 Preamp
Pass Labs X250.5 Amp
Harbeth 30.1 stand mount speakers
Puritan Labs PSM 156 power conditioner. (less "edgy" sound with it in system)
System is run all balanced with fairly costly Cardas interconnects.
All input is welcome. Thanks in advance.
Happy listening.
