A sub with L & R RCA inputs???

These are great responses..Many thanks Nsgarch..I have since moved and have not updated my pictures and have a totally different arrangement. The Woodmere's are now in a room with more breathing room and have fully opened up. But since the Coda Csi hd this capability I thought it wouldn't hurt to put this out for some opinions. The bass is even deeper in the new enviroment and I couldn't be happier (I think)...Since the Coda has been a blessing to the Woodmere's I wonder what the Sub would add if anything.

Shakedown, the "subwoofer" main outputs on the back of your Coda are exact duplicates of the "preamp" main outputs. Just different labels. In theory, the Woodmeres should give you all the low frequency bass you need. In pactice though, as things are now, it won't be well controlled low bass (good damping), unless you get the amp(s) next to the speaker(s). If you keep the Coda near your listening chair, you'll be running rather long speaker cables, which ruin good bass transient response. If you put the Coda between the speakers, that's a little bit better solution for good bass control, but incovenient from a user standpoint.

All this is a good argument for separate components over integrateds, which IMO are best reserved for bedroom systems. In your situation, you'd get a lot better performance out of your main speakers by using a pair of monoblock amps next to the speakers, and preamp and sources next to your listening position. A preamp preferably with balanced outputs to drive longer cables to the monoblock amps (although with well designed/shielded single-ended cables, you can go up to 40 ft with no problem.) As things are now, adding a subwoofer won't do anything to improve the (somewhat less than optimum) performance of your Tylers. So I'd work toward improving the relationship between your main speakers and the amp(s) that drive them.

Nsg....hmmm...Well I am quite impressed with the Coda and its driving capabilities...I have completely removed my Modwright 9.0 from my system and I would love to bring it back from time to time for the love of tubes...Any suggestions on some good monoblocks then that might mate well with my Modwright...I did send it back to Dan for the upgraded rectified power supply when I recently had it overhauled before I stored it...wish to bring it back soon...Right now the distance between my speakers is 16 ft.

" Right now the distance between my speakers is 16 ft."

That's quite far apart . . . do you mean the distance from your speakers to your listening position?

If you like tubes, then the best place to reap their benefit(s) is in a device that actually amplifies the signal. That would be amplifiers (obviously;~), phonoamps, and microphone amps. Preamplifiers are basically source selectors and volume/balance controllers. They don't really do any 'amplifying'. What we want in a preamp is QUIET! Before a signal gets to the main amplifier, having tubes in the signal path only adds "tube hiss" and who needs that? We do put up with a little tube hiss from phonoamps b/c you get great phono amplification (bang for the buck) with tubes. Not to say there aren't some really great ss phonoamps, but they all start a ten times the price of a similarly great sounding tube phonoamp -- of course you don't play vinyl, so none of that concerns you -- but I'm just saying ;~)

If you want a great sounding system starting from where you are now, you should think about a nice pair of tube monblocks for your Tylers. I think the Woodmeres are fairly efficient (the website no longer lists the specs for them) so you wouldn't need a super powerful amp; but more important, if you want to use tubes to enjoy the quality of all the Woodmeres' Scan-Speak drivers, both bass and mids, then you want to preserve all the damping ability that a tube amp can muster -- which means keeping speaker cables as short as possible. Thus the recommendation for monoblocks. If you want to use a ss amp, it could practically be in the garage as long as the speaker cables' conductors are big enough (10AWG). But tube amplification would be delicious with those speakers. And some day, if you want to bi-amp them, and get a couple of modest ss amps just for the woofers, you'd be way ahead (sonically) for the money, than you would be just throwing a sub into the current mix (even though Tyler makes some nice subs ;~)
