been looking at the rr2150 for about a year,was impressed with the retro look and all the features, so i ordered one, loved it except for one major detail, compared to my other recievers.carver 752,carver mx 130 marantz 2220b ,kenwood kr 7600 and a gte/sylvania 2400 the rr2150 was lacking on tonal punch on every other recievier i mentioned with bass and treble set at flat ingageing the loudness switch and adding the bass control produced lots of bass punch with th rr2150 it just wasnt there even with everything upall the way,yes i had the cross over on back set to bypass aftera week of compareing against above mentioned recievers i was about to pack it up and thought maybe its the amp section that didnt have the punch so i tried it in preamp mode against my parasound 850 pre with a 205wpc parasound amp and klipschorn apkrs .....same thing no bass punch with tone controls cranked full blast so sadly i returned it

Im not a tech or a engineer so my question is what determins the amount or level of bass or treble is it the pots themselves or is it in the circuitry. ?

In most cases it is a combination of what is available in the material and the capability of the speakers in your system to reproduce the sound. Many of us have speakers which go down to the 30-40 hz range but require a lot of power to do so. Many of us also have subwoofers dedicated to just those frequencies so we can supply more power to the mains at frequencies above the crossover. If I were in your shoes I would check the capabilities of your speakers and adjust your crossover such that it kicks in just slightly above the lowest range for your mains and let the subwoofer do the rest above the crossover point. Remember that although the 2150 comes with bass and treble adjustments it is set up originally for neutral use and to accurately reproduce the material being played. I would not expect you to have to crank the bass controls way up to get good response. Perhaps you got a defective unit or perhaps you are a bassaholic and need a bigger fix.

My speakers sre klipshorns, i was told by outlaw that returnds are given upon delivery and that it would take up two weeks till bench tested that was over a month ago no word if the unit was defective,and i specificly told them that if it was i want a nother unit

This has nothing to do with spkrs ! I compared this rr2150 against all the above mentioned recievers and the unit i recieved came up short on bass punch i even compared it in pre amp mode..same issue

Hi Cogin,

Apologies if there was any miscommunication. Two days after receiving the RR2150 at our facilities, you were issued a credit. Normally, after returning a unit, there is no follow up. Although that is usually the case, our notes do indicate we were to give you a call if we found any issues with your RR2150, so we could discuss getting you a replacement unit; we found there was no issue with the unit.

Once again, we apologize if there was any miscommunication or misunderstanding. If you do have any further concerns, please feel free to contact us, Monday - Friday 9:00am - 5:00pm EST, at (866) OUTLAWS.

Ok so we both have. Klipsch speakers. Do you have a subwoofer connected?

No sub

Like i said at top of page with all those comparable recievers,i could not turn the tone controls all the way up without over doing it but with the rr2150 tone controls maxed out it was lacking bass responce

It may be that the other receivers have more gain on the controls than the 2150. I would expect that you would get better performance from any setup using a sub to do the low freq stuff. Even bass capable speakers like the Klipsch can benefit because of the additional headroom available when the sub takes on the heavy stuff. I suspect that when Outlaw designed the 2150 they had the use of a sub in mind with a set of bookshelf speakers and didn't expect someone to crank the tone controls all the way up to get as much bass as you want.
