Default Problems with HT speaker setup

Hi all,
I am stuck in a mess and was hoping I would get some ideas here.
I have made an MTM with Vifa TC18WG49-08 and D27TG-05-06. Now I use the speakers with a DIY 70W amplifier. It sounds good with that amp. I am now setting up my home theatre system. But the MTM does not sound so good with my Denon AVR1403 receiver. The output is rather less and I have to pump up the volume. The receiver heats up too much if I use the MTM with it and the sound is not so good. The receiver plays better with 8 ohm speakers. So obviously my Denon does not handle 4 ohms very well.
What I thought was to break up the MTM and make front TM speakers with TC18 and D27 and use the other two TC18s for a centre channel speaker.
Alternately, I could buy a pair of Vifa P17WJ and use it with the D27 to build a TM front tower. Anyway the P17WJ midbasses are also better than the TC18 and could be used for music also.
What do you guys think?

Cheers,
Vivek

Going 8ohms will make it easier for the receiver but if it is anything like the AVR1702,then you have to turn the volume knob pretty far to the right to get a decent sound level.

Has the reciever got preouts so as you can use your diyamp to drive your MTMs?

cheers arthur

jaudio,
You are right. Turning up the volume too much will be pushing the limits of the receiver. That is something I do not want to do, right?

Arthur,
The receiver does not have pre outs for the 5 channels. It has only tape out and vcr line level outputs. I tried hooking up the tape out/ vcr to the external amp but it works only in the case of tuner/ CD/ auxiliary inputs. By doing this the fronts are not controlled by the master volume on the receiver.

You can always get a line level signal from your receiver using a dividing network or there are some commercial ones you can buy.

Not the best solution but it would work for HT and please read the notes on grounding as it can end in tears.

The best option is dedicated speakers for HT and music.

But how would small bookshelves with the TC18 and D27 for the front and surrounds work out?

You could also try using the headphone out on your Denon for your diyamp. Again not the ideal solution but might be a decent short term solution.

I could use the headphone out but it will not be effective when I am using a 5.1 setup, will it?

If your receiver allows you to power your speakers and your headphones at the same time you can use the reciever to power your center and surrounds and use your diyamp to power your mains. Plus your headphone jack is controlled by the master volume.

I had a similar setup for awhile so I could use my NAD 304 to power my mains until I found a technics ac-sh300 surround processor.

Sadly, it does not. I get the headphone output only when front speakers A and B are switched off.
