I have Forte 1's and they have tons of bass. I am running them with a Denon avr 2805. If you are using an AVR receiver and a subwoofer it could be a subwoofer phase problem. If you are using a HT system and no subwoofer make sure the HT settings show no sub.If it thinks there is one it may send all low frequency (depending on the settings) below 120 hz to the sub eliminating all the bass from your Forte's. Since you have a HT receiver, it will most likely default to expecting a sub and you would need to disable it in the programming if don't have one. I am just speculating, not assuming that you didn't already do this. To the rest of us here, I installed the Crites Titanium tweeter diaphragms last night. It took about 30 minutes to complete both speakers. There is a much enhanced upper range with better clarity. As the forum has indicated, it was likely the biggest bang for the buck with improvement. Thank you all who have posted your upgrades successes.
