People complain about lack of bass, not enough mid range. Solution?

I finally got my best bass response. Running full range speaker t s and 4 subs

Yes, multi-subs along with bass traps and absorption of the strong early reflections are the best way to tame the acoustics. This done properly will essentially remove the damaging effects of an untreated room and allow you to hear the acoustics of the venue. Dialing this in with a microphone and measurement system is the fastest and easiest way to get the best result. Waterfall plots will reveal the RT60 and indicate the problem areas.

Lately I have been wiring my Cornwall 4's with 10 gauge "western electric" cloth covered cable to the lower speaker taps and and then using jumpers to the allegedly "treble" taps on the Cornwalls with 16 gauge of the same vintage wire. Technically, the current going to the tweeters is overridden by what is going to the woofers, so it should make no difference. However, I am noticing that with this arrangement it is easier to further manage the potential brightness of the horn tweeter signal. The REL active subs with the "high level" connections also further provide playing room.

Also, a further variable is to switch up cabling to the Audion monoblocs. Most of the system is power cabled by Shunyata Delta NR v2's connected to an old Shunyata Hydra, but the monoblocs are powered from an old Shunyata "Cyclops" power conditioner with Anticables Level 3 power cables juicing the monoblocs. Routing the Anticables from the Cyclops to the Audions gives a slightly softer presentation with a very sight reduction in dynamics. Plugging the Anticables directly into the wall outlets (Hubble outlets,dedicated line) gives slightly more treble energy and more bass impact at the same time. Since the Audions are already very dynamic the slight loss of dynamics can be a welcome thing.

The Audions are still breaking in - so is the Holo Serene pre which is just starting to sound more "liquid" as forecast by reviewers, so things are changing for the better on a daily basis. The more I get into this hobby the more I feel like a hot-rodder tinkering with iron and rubber in the driveway while the rest of the family looks on with bemusement.
