Loudspeakers that go LOUD?

I hope that beemerrider does not ignore the Tyler bass units by labeling them subwoofers. They will fit right under your monitors and make them real full range speakers all the while giving you the volume that you seek. They will not take up more floor space or other wise, ugly up, the room. Aesthetically ideal and below budget!
The concern about the monitors droping below 4 ohms in the bass range would be negated by the bass units taking over the bass duties. I feel the aesthetic concern is a major one. We don't want to spend the hugh amounts of money and time that we invest in creating our home enviornments just to throw it all away in search of an audio parameter. In this case extra volume or as beemerrider sees it, adequate volume. It's a valid goal but not one where you would sacrifice the overall aesthetic of the room. That's why I belive that the Tyler bass units would accomplish his goals without degrading the aesthetic of the room.

To add to Robertson35's comments/recommendations.........

Apart from amplifier considerations, one of the benefits of the added bass unit which might be overlooked and is pertinent to Beemeriders concerns......By adding the bass unit which crosses out the main speakers well above 100 hz you effectively reduce the demands on the main units mid range drivers - this will result in a much purer tone, especially at 'increased' volume levels.

FWIW.

I've come to believe that the use of high efficiency speakers is the key. Consider a pair of Zu Druids. At 101 db efficiency, they will deliver much more SPL than you will require in that room without any breakup using your present amplification. Zu is known for playing loud while remaining exceptionally coherent. They will really boogie.

Rather than GO loud I think you should pay attention to "sound good loud". A lot of speakers change their response curves at different volumes - will sound flat at low volume - and screechy, harsh or compressed at high volumes - so there is only a small range in the middle that sounds just right.

Revel claims they make sure the response is flat across all volumes. And my Joseph Audios seem to do this right also - its easy to turn them up loud and not realize it because they do not get harsh at loud volumes. Coincidentally both these speakers use very sharp crossover slopes.

As things stand, you'll either add that "bass unit" (i.e. not a subwoof) -- or you'll have to purchase new, fullish range speakers & a new amp. Indeed, if you keep the speakers you'll probably need a higher powered amp anyway (unfortunately): that's judging from your quick description up top.

A side clarification for our Seas afficionado: Seas happens to be in Norway -- not Denmark.
