Is the Denon AVR987 powerfull enough to power upgraded speakers?

Hello forum!!! My first post..yahooo!!


I currently have a Denon 987 and want to know if this receiver can handle bigger speakers such as the TSi series or the Monitor series or even larger. My main purpose of this setup will be for movies(7.1) and music occasionally. I have an open floor plan. Really hard to describe the layout as the system will be on one end... and to the left will be the rest of the house(approx 500sq feet) but the main area where the setting will be is approx 75sq feet.

The Denon AVR987 specs(from excerpt on the web):
The AVR987 is a real workhorse, featuring high quality, wideband audio amplification, providing 110 watts of power output (8 ohms, 20Hz-20kHz, 0.05 percent THD) for each of its seven main channels. A large capacity power supply includes a high current power transformer along with discrete power output devices on all seven amplifier channels for the highest dynamic range and superb reproduction clarity. The power amp circuits of the AVR987 have been meticulously designed to reproduce exceptionally high sound quality with a wide frequency response from 10 Hz to 100 kHz. The AVR987 is equipped with a total of 7 power amps including two for the Surround Back channel speakers.

The Denon is currently powering my Onkyo HTIB 7.1 system speakers..specs are below
HTIB Specs
Powered Subwoofer (SKW-530)
■ Center Speaker (SKC-530C)
2 Way Bass-reflex 8 Ω 110 W
86 dB/W/m
2 Way Bass-reflex 8 Ω 110 W
86 dB
■ Front Speaker (SKF-530F)
■ Surround Speaker (SKM-530S/SKB-530)
2 Way Bass-reflex 8 Ω 110 W
86 dB/

I am really favoring the Polk TSi 400's fronts, CS10 center and the PSW111 sub. But would appreciate any inputs as I am just a Noob wanna be and do not want to invest on speakers that my system may not be able to handle.

Welcome to Club Polk!

You're fine with that AVR. And it's a "nice" one. I ought to know because I have its sister unit the AVR 2807 (more or less the same unit, cosmetic differences). This is before Denon started to cheap out the series and add tons of features at the expense of "build" quality in the lower to mid units.

I've run some TSI-300s on the Denon as well as my M-70s at one point. Definitely powerful enough for the size room you have. And, what's good is that this unit and yours has Pre-outs. So if you want to pump it up you can add a power amp into the mix.

My M-70s really opened up when I put an Adcom GFA-555 on the Denon. But that was mostly for two channel. You won't have to worry about HT performance in such a small space.

In any case. TSI-400s, no problem! You're good!

Newbee, welcome to Club Polk. You've already gotten good advice and I'll go into a little more detail why you should have no concern. New listeners(and some not-so-new)often assume that a bigger speaker enclosure with more speaker drivers in it calls for more power, but frequently although not always, the opposite is true. Often the bigger speaker is more efficient than the small one in its use of power, and actually needs less than the small one at given sound levels. This is the case in your situation, since your HTIB speakers yield an 86dB sound level(quite loud)for 1 watt of input power, while the TSI-400s have a significantly higher 91dB rating for 1 watt. Simply put, this means that the TSI-400s use a bit less than half the power at a given sound level.

The TSI-400s are excellent, and you'll be able to enjoy great sound through them for many years to come.
