For those of you who have read my recent post about my new Coincident Dynamo SET amplifier with 300B's, you're aware of a controversial situation where the pairing of this amp with Zu Omen Dirty Weekend speakers sounds great with acoustic music, and not so great with electric. It isn't a problem for me, as I'm more than happy to play only acoustic music on that bedroom system. However, I'd be interested, and even curious to figure out if this is due more to the amp's or the speakers' character. The only way to find out, I guess, is to hear the amp with different speakers. Now, the Zu's are full-range + super-tweeter. I would like to try another pair of full-range single-driver speakers that have NO super-tweeter. They need to be at least 94 dB efficient, and have bass extension to at least 40 Hz, preferably to about 35-36 Hz (I hate sub-woofers, and will not use one). Also, they need to be front- or bottom-ported (or sealed, if those are even made). No rear porting - they are for a small 11 x 11 bedroom. No horns - horns need a bigger room. Obviously, they also need to be fairly compact, given the size of my room, so no Cornwall suggestions, please. And last, but not least - they need to be sanely priced, so - no $12,000 DeVore suggestions, please. I paid $1,200 for my Zu's ($200 for better finish), so, ideally, I'd like to stay within the same range, plus or minus a few (hundred) bucks. Preferably new, but I can consider used, if they come from an audiophile home and are well-kept. I know AN UK makes some "affordable" models, but there are no prices published, so I'm not sure what their definition of affordable is. I am aware of Omega, but they won't do because of rear porting - my bedroom is rather small, and I cannot bring the speakers out from the wall. I also know of Blumenstein - the only model of theirs I would consider also has the super-tweeter, so it's a no go. So, I'm looking for your suggestions for something I don't already know, given the parameters described above. First-hand opinions of people who run low-power SET amps are especially sought. Thanks in advance.
