Speaker placement within your room will have a substantial effect on the bass response you get from just about any speaker. Not knowing the specifics of what placement limitations you may have, it's hard to say what would work best in your situation. I can say that you can usually squeeze out another 10HZ or so of usuable bass response from the manufacturers specs if you have the room to move your speakers around. How much effect this has on the other frequencies is pretty much a trial and error thing within your own room.

Perhaps the safest play would be to buy the speakers that sound the best with your gear and within the design limits and simply add a sub for the low frequencies. PSB makes some fine subs for not much money and to the best of my knowledge, they all have a variable crossover so you shouldn't have to worry too much about upsetting the balance of your midrange...once you have found the speakers that satisfy you from about 80HZ on up.

I know exactly where your coming from in regards to trying to duplicate what you hear in your car. My car system can cause the mirrors to bounce with every drum hit. The problem is that ina car your sitting in very close proximity to the speakers and you have a ton of "room gain". BTW, I did notice that when I sit within 3 feet of my home speakers I can nearly duplicate what I hear in my car so I believe that proximity is a big part of why car systems have so much pop. To bad it's not proctical for normal listening.

Now, how to duplicate this in the home. I think that you'll be looking for large, and expensive, speakers like the high end Klipschhorns, OR using a system suplemented with some extras. First, start looking for a subwoofer that can be adjusted to blend well with you choice for primary speakers. Second, you may want to hit Ebay and look for a DBX 3BX II or DBX 3BX DS. Normally they sell for around 250 USD (the 5BX can hit over 600 USD). The DBX 3BX is a 3 band dynamic range expander and the model II and DS both had a special circuit that increases the "hit" for things like drums. DBX called this DAIR (I believe it stands for Dynamic Audio Impact Recovery) and it's actually pretty effective at making drum sounds really pop. Unfortunately, DBX got so fed up with dealing with consumer retailers that they pulled out of consumer electronics and you can only find the 3BX on the used market. BTW, DBX didn't offer DAIR on the early versions on the 3BX, only the later versions. If you can't find a later 3BX, the 4BX and 5BX expanders also incorporated the DAIR circuit and so did their DX3 and DX5 CD players. Just be careful with your volume levels when using these units, crank it up too much and you'll find yourself blowing up woofers in short order. That DAIR circuit can make a woofer dance like nothing else and at high volumes you'll find the woofer hitting it's excursion limits quite quickly.

If you like the sound of the Klipschhorns, Listen to a pair of Klipsch Heresys, or LaScalas. I have lived with both of these models and find them very usable for all kinds of music including rock. You get a lot of slam for the watt. You save money on the Amplifier because of the high efficency. These have been very popular for many years and so there are usually very good examples available used.

id do have to agree with the klipsch-these babys rock, ac dc, judas priest- primus

I would suggest a pair of Gallos Reference 3.1's. But not with the amplification you're currently running. However, I've heard the Gallos do what you want with far less intrusive sound than the Klipsch can manage. The Gallos can play exceptionally loud while maintaining a very high quality of reproduction. Using their "subwoofer" amplifier to drive the second voice coil of the low frequency unit, you can tune the speaker to achieve almost any degree of "slam" you desire. They are also very easy to place in a room and have a wide dispersion pattern that minimizes sweet spot listening positions. However, to get the sort of bass you want, you are going to have to include room treatments also or you will forever run into muddy bass due to the simple physics of the situation.
